HIV/AIDS News Releases

HIV Vaccine Awareness Day 2019
May 18, 2019

Since the first cases of what would become known as HIV/AIDS were initially reported in 1981, scientists and public health officials have been working to better understand HIV, develop strategies to effectively treat and prevent infection, and bring about an end to the pandemic. This effort remains a critical focus globally and for the United States.

NIH Trial Evaluates Long-acting HIV Medication in People Unable to Adhere to Strict Daily Regimens
May 9, 2019

A clinical trial to evaluate long-acting antiretroviral therapy (ART) for maintaining HIV suppression in people for whom adhering to conventional daily oral ART has been a challenge has begun at research sites across the United States. The study, called Long-Acting Therapy to Improve Treatment Success in Daily Life, or LATITUDE, will help determine whether a combination of two experimental injectable formulations of ART are superior to conventional oral ART in managing HIV infection in this population.

In Rare Cases, Immune System Fails Despite HIV Suppression
April 18, 2019

Antiretroviral therapy (ART) is usually very effective at suppressing HIV in the body, allowing a person’s immune system to recover by preventing the virus from destroying CD4+ T cells. Scientists have now identified a rare, paradoxical response to ART known as extreme immune decline, or EXID.

Novel Antibody May Suppress HIV for Up to Four Months
April 17, 2019

Regular infusions of an antibody that blocks the HIV binding site on human immune cells may have suppressed levels of HIV for up to four months in people undergoing a short-term pause in their antiretroviral therapy (ART) regimens, according to a report published online today in The New England Journal of Medicine. Results of the Phase 2, open-label study indicate the antibody, known as UB-421, was safe and did not induce the production of antibody-resistant HIV.

Researchers Report High Rate of Viral Suppression Among People New to HIV Care
March 7, 2019

Eighty-six percent of individuals who entered HIV care soon after diagnosis maintained viral suppression after 48 weeks during a clinical trial conducted at four National Institutes of Health (NIH)-funded Centers for AIDS Research (CFARs) across the United States. Participants in the clinical trial, called iENGAGE, achieved viral suppression in an average of just 63 days.

Tuberculosis Diagnosis in People with HIV Increases Risk of Death Within 10 Years
March 6, 2019

Among people with HIV in Latin America, those diagnosed with tuberculosis (TB) at an initial clinic visit were about twice as likely to die within 10 years as people not initially diagnosed with TB, according to findings from a large observational study. This increased risk persisted despite the availability of TB treatment and mirrored patterns seen previously in HIV-negative populations, according to research supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

HIV Prevention Study Finds Universal "Test and Treat" Approach Can Reduce New HIV Infections
March 4, 2019

New HIV infections declined by 30 percent in southern African communities where health workers conducted house-to-house voluntary HIV testing, referred people who tested positive to begin HIV treatment according to local guidelines, and offered other proven HIV prevention measures to those who tested negative. Local guidelines evolved during the study from offering HIV treatment based on immune health to offering immediate treatment for all. 

NIH Clinical Trial to Track Outcomes of Liver Transplantation from HIV-Positive Donors to HIV-Positive Recipients
February 14, 2019

The first large-scale clinical trial to study liver transplantation between people with HIV has begun at clinical centers across the United States. The HOPE in Action Multicenter Liver Study will determine the safety of this practice by evaluating liver recipients for potential transplant-related and HIV-related complications following surgery. The study is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and follows the 2018 launch of a similar study evaluating kidney transplantation between people with HIV.

Study of PrEP and Vaginal Ring for HIV Prevention Begins in Girls and Young Women
February 7, 2019

A clinical trial has begun to examine the safety and use of two HIV prevention tools—oral pre-exposure prophylaxis (PrEP) and a vaginal ring—in adolescent girls and young women in southern Africa. Funded by the National Institutes of Health, the trial is designed to contribute to the delivery of safe, effective and desirable choices of HIV prevention methods for adolescent girls and young women, who are disproportionately affected by the HIV epidemic.

NIH-Supported Scientists Develop Tool to Measure Success of HIV Cure Strategies
January 30, 2019

Scientists funded by the National Institutes of Health have developed a new assay to accurately and easily count the cells that comprise the HIV reservoir, the stubborn obstacle to an HIV cure. This advance will enable researchers who are trying to eliminate the HIV reservoir to clearly understand whether their strategies are working. The research was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of NIH.

The Science Is Clear: With HIV, Undetectable Equals Untransmittable
January 10, 2019

In recent years, an overwhelming body of clinical evidence has firmly established the HIV Undetectable = Untransmittable (U=U) concept as scientifically sound, say officials from the National Institutes of Health. U=U means that people living with HIV who achieve and maintain an undetectable viral load—the amount of HIV in the blood—by taking and adhering to antiretroviral therapy (ART) as prescribed cannot sexually transmit the virus to others.

NIH to Fund HIV Care and Prevention Research in Vulnerable Southern U.S. Communities
December 11, 2018

The National Institute of Allergy and Infectious Diseases will fund a series of collaborations with medical research institutions in the southern United States to test new ways of implementing HIV treatment and prevention tools in counties with some of the highest rates of new HIV cases nationwide. The U.S. South overall has the highest rates of new HIV diagnoses, people living with HIV, and HIV-related deaths of any U.S. region. 

NIH Statement on World AIDS Day, December 1, 2018
November 30, 2018

Each year on World AIDS Day, we reflect on the remarkable progress that has been made against HIV. Indeed, we have come a long way since the disease now known as AIDS was first reported in 1981. 

Meeting the Challenge of Engaging Men in HIV Prevention and Treatment
November 29, 2018

A new commentary from National Institutes of Health scientists asserts that engaging men in HIV prevention and care is essential to the goal of ending the HIV pandemic. The article by Adeola Adeyeye, M.D., M.P.A., and David Burns, M.D., M.P.H., of the National Institute of Allergy and Infectious Diseases (NIAID) and Michael Stirratt, Ph.D., of the National Institute of Mental Health (NIMH) also discusses potential solutions.

Combination HIV Antibody Infusions Safely Maintain Viral Suppression in Select Individuals
September 26, 2018

A small group of people living with HIV sensitive to two potent anti-HIV broadly neutralizing antibodies (bNAbs)—3BNC117 and 10-1074—tolerated multiple infusions of the antibodies and suppressed HIV for more than 15 weeks after stopping antiretroviral therapy (ART). The new findings, from a pilot clinical trial supported by the National Institutes of Health (NIH), the Bill & Melinda Gates Foundation and others, are reported today in Nature.

NIH Launches Study to Test Combination Antibody Treatment for HIV Infection
September 20, 2018

A clinical trial testing infusions of combination antibodies in people living with HIV has begun at the National Institutes of Health. The early-phase clinical trial will evaluate whether periodic infusions of two highly potent, HIV-specific, broadly neutralizing antibodies (bNAbs)—3BNC117 and 10-1074—are safe in people living with HIV. The study also will gather preliminary data on how effectively the bNAb infusions, delivered together every two to four weeks, suppress HIV following discontinuation of antiretroviral therapy (ART). 

Novel Intervention Halves Rate of Death Among People Living with HIV Who Inject Drugs
August 30, 2018

An intervention designed to facilitate treatment for HIV and substance use was associated with a 50 percent reduction in mortality for people living with HIV who inject illicit drugs, a study has found. In addition, the people who received the intervention were nearly twice as likely to report being in treatment for HIV and substance use after one year as those who received their national standard of care. They also were about twice as likely to have suppressed their HIV to undetectable levels after one year.

HIV/AIDS Research Yields Dividends Across Medical Fields
August 28, 2018

Since the first cases of AIDS were reported in the United States 37 years ago, the National Institutes of Health has invested more than $69 billion in the understanding, treatment and prevention of HIV/AIDS. Beyond the development of life-saving medications and innovative prevention modalities, such research has led to numerous advances outside the HIV field, according to a new commentary from experts at NIH’s National Institute of Allergy and Infectious Diseases (NIAID). 

NIH Officials: Closing Treatment Gaps Critical to Ending the U.S. HIV Epidemic
August 20, 2018

Daily antiretroviral therapy (ART) that suppresses HIV to levels undetectable by standard blood tests is lifesaving for individuals living with HIV and prevents sexual transmission of the virus to others. The public health community must use targeted interventions, however, to do a better job of reaching populations with low levels of viral suppression, according to experts from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. 

During HIV Infection, Antibody Can Block B Cells from Fighting Pathogens
August 13, 2018

For the first time, scientists have shown that in certain people living with HIV, a type of antibody called immunoglobulin G3 (IgG3) stops the immune system’s B cells from doing their normal job of fighting pathogens. This phenomenon appears to be one way the body tries to reduce the potentially damaging effects of immune-system hyperactivity caused by the presence of HIV, according to the investigators, but in so doing, it also impairs normal immune function. 

Fauci: HIV Remission Free of Antiretroviral Therapy Is a Feasible Goal
July 25, 2018

Long-lasting control of HIV infection without antiretroviral therapy (ART) is a feasible goal that deserves vigorous pursuit, Anthony S. Fauci, M.D., will assert during a lecture on Wednesday, July 25 at the 22nd International AIDS Conference (AIDS 2018) in Amsterdam. Dr. Fauci directs the National Institute of Allergy and Infectious Diseases (NIAID), part of the U.S. National Institutes of Health. His lecture is titled, “Durable Control of HIV Infection in the Absence of Antiretroviral Therapy: Opportunities and Challenges.”

Multi-Disease Health Fairs, Universal "Test and Treat" Help East African Communities Achieve HIV Benchmarks
July 25, 2018

People living with HIV in rural East African communities that hosted annual community health campaigns initiated antiretroviral therapy (ART) earlier and had higher levels of overall survival and viral suppression than communities receiving standard HIV care, according to study data presented today at a press conference at the 22nd International AIDS Conference (AIDS 2018) in Amsterdam.

Imaging Technique Illuminates Immune Status of Monkeys with HIV-Like Virus
July 12, 2018

Findings from an animal study suggest that a non-invasive imaging technique could, with further development, become a useful tool to assess immune system recovery in people receiving treatment for HIV infection. Researchers used single-photon emission computed tomography (SPECT) and a CD4-specific imaging probe to assess immune system changes throughout the bodies of macaques infected with SIV, a simian form of HIV, following initiation and interruption of antiretroviral therapy (ART).

HIV Vaccine Elicits Antibodies in Animals that Neutralize Dozens of HIV Strains
June 4, 2018

An experimental vaccine regimen based on the structure of a vulnerable site on HIV elicited antibodies in mice, guinea pigs and monkeys that neutralize dozens of HIV strains from around the world. The findings were reported today in the journal Nature Medicine by researchers at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and their colleagues. 

NIH Statement on HIV Vaccine Awareness Day, May 18, 2018
May 18, 2018

As a result of the many scientific research advances over 37 years, we now have highly effective methods of HIV treatment and prevention. These tools have allowed us to make important strides in reducing the burden of HIV in the United States and globally.

NIH Clinical Trial to Track Outcomes of Kidney Transplantation From HIV-Positive Donors to HIV-Positive Recipients
May 7, 2018

The first large-scale clinical trial to study kidney transplantations between people with HIV has begun at clinical centers across the United States. The HOPE in Action Multicenter Kidney Study will determine the safety of this practice by evaluating kidney recipients for potential transplant-related and HIV-related complications following surgery. The study is sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Genetically Altered Broadly Neutralizing Antibodies Protect Monkeys from HIV-Like Virus
April 16, 2018

Two genetically modified broadly neutralizing antibodies (bNAbs) protected rhesus macaques from an HIV-like virus, report scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. After introducing genetic mutations into two potent HIV bNAbs, researchers prepared intravenous infusions of two bNAbs known as 3BNC117-LS and 10-1074-LS.

High Uptake and Use of Vaginal Ring for HIV Prevention Observed in Open-Label Study
March 6, 2018

Nearly 90 percent of participants in an open-label study of a vaginal ring infused with a drug to prevent HIV are using the monthly ring at least some of the time, according to an interim analysis of study data. In addition, the rate of HIV infection among participants in the open-label study, which has no placebo arm for comparison, is half of what might be expected in the absence of the ring, according to mathematical modeling that has significant limitations. 

One-Month Tuberculosis Prophylaxis as Effective as Nine-Month Regimen for People Living with HIV
March 5, 2018

A one-month antibiotic regimen to prevent active tuberculosis (TB) disease was at least as safe and effective as the standard nine-month therapy for people living with HIV, according to the results of a large international clinical trial. Adults and adolescents in the trial were more likely to complete the short-course regimen—consisting of daily doses of the antibiotics rifapentine and isoniazid for four weeks—than the standard nine-month regimen of daily isoniazid.

Broadly Neutralizing Antibody Treatment May Target Viral Reservoir in Monkeys
March 4, 2018

After receiving a course of antiretroviral therapy for their HIV-like infection, approximately half of a group of monkeys infused with a broadly neutralizing antibody to HIV combined with an immune stimulatory compound suppressed the virus for six months without additional treatment, according to scientists supported in part by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.

Study Links Gut-Homing Protein Levels with HIV Infection Risk, Disease Progression
January 24, 2018

For the first time, scientists have shown a relationship between the proportion of key immune cells that display high levels of a gut-homing protein called alpha-4 beta-7 at the time of HIV infection and health outcomes. Previous research illustrated this relationship in monkeys infected with a simian form of HIV. 

15 Years Later, PEPFAR Continues to Save Lives
January 24, 2018

Experts from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, have penned a New England Journal of Medicine perspective recognizing the United States President’s Emergency Plan for AIDS Relief (PEPFAR) for 15 years of implementing an innovative program to prevent, treat, and care for persons living with HIV and AIDS. The authors stress that continued support for the U.S.

NIH Begins Large HIV Treatment Study in Pregnant Women
January 24, 2018

The National Institutes of Health has launched a large international study to compare the safety and efficacy of three antiretroviral treatment regimens for pregnant women living with HIV and the safety of these regimens for their infants. The study will evaluate the current preferred first-line regimen for pregnant women recommended by the World Health Organization (WHO) and two regimens containing newer antiretroviral drugs that are becoming more widely used.

NIH Study Supports Use of Short-Term HIV Treatment Interruption in Clinical Trials
January 11, 2018

A short-term pause in HIV treatment during a carefully monitored clinical trial does not lead to lasting expansion of the HIV reservoir nor cause irreversible damage to the immune system, new findings suggest.

NIH Launches HIV Prevention Trial of Long-Acting Injectable Medication in Sexually Active Women
November 30, 2017

The first large-scale clinical trial of a long-acting injectable medication for HIV prevention in sexually active women has begun. The study in southern and eastern Africa will examine whether a long-acting form of the investigational anti-HIV drug cabotegravir injected once every eight weeks can safely protect women at risk for HIV infection. The only drug regimen currently licensed for HIV pre-exposure prophylaxis, or PrEP, is the anti-HIV medication Truvada taken daily as an oral tablet. The U.S.

NIH and Partners Launch HIV Vaccine Efficacy Study
November 30, 2017

The National Institutes of Health and partners have launched a large clinical trial to assess whether an experimental HIV vaccine regimen is safe and able to prevent HIV infection. The new Phase 2b proof-of-concept study, called Imbokodo, aims to enroll 2,600 HIV-negative women in sub-Saharan Africa. Of 1.8 million new HIV infections worldwide in 2016, 43 percent occurred in eastern and southern Africa, with women and girls disproportionately affected.

Combination HIV Prevention Reduces New Infections by 42 Percent in Ugandan District
November 29, 2017

A study published today in the New England Journal of Medicine provides real-world evidence that implementing a combination of proven HIV prevention measures across communities can substantially reduce new HIV infections in a population.

Investigators found that HIV incidence dropped by 42 percent among nearly 18,000 people in Rakai District, Uganda, during a seven-year period in which the rates of HIV treatment and voluntary medical male circumcision increased significantly.

Durable End to the HIV/AIDS Pandemic Likely Will Require an HIV Vaccine
October 9, 2017

Despite remarkable gains in the treatment and prevention of HIV infection, development of an effective HIV vaccine likely will be necessary to achieve a durable end to the HIV/AIDS pandemic, according to a new commentary from Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. 

Three-in-One Antibody Protects Monkeys from HIV-Like Virus
September 20, 2017

A three-pronged antibody made in the laboratory protected monkeys from infection with two strains of SHIV, a monkey form of HIV, better than individual natural antibodies from which the engineered antibody is derived, researchers report in Science today.

NIAID Scientists Illuminate Mechanism of Increased Cardiovascular Risks with HIV
August 30, 2017

Scientists at the National Institutes of Health have expanded the understanding of how chronic inflammation and persistent immune activation associated with HIV infection drive cardiovascular disease risk in people living with HIV. People living with HIV are up to twice as likely to experience heart attacks, strokes and other forms of cardiovascular disease as people who do not have the virus, even when HIV infection is well-controlled with the use of antiretroviral therapy. 

In Adolescents, Oral Truvada and Vaginal Ring for HIV Prevention Are Safe, Acceptable
July 25, 2017

A monthly vaginal ring and a daily oral tablet, both containing anti-HIV drugs, were safe and acceptable in studies of adolescents, two teams of investigators reported today at the 9th IAS Conference on HIV Science in Paris. The experimental ring is designed for HIV prevention and the oral tablet is already used for this purpose in adults. Adherence to the ring was high, while adherence to the tablet was moderate and diminished substantially when study visits became less frequent.

Drug Interaction Concerns May Negatively Affect HIV Treatment Adherence Among Transgender Women
July 24, 2017

Transgender women—people whose birth certificates indicate or once indicated male sex but who identify as women—are at high risk of HIV acquisition, and thus are a key population for HIV prevention and treatment efforts.

Child Living with HIV Maintains Remission Without Drugs Since 2008
July 24, 2017

A nine-year-old South African child who was diagnosed with HIV infection at one month of age and received anti-HIV treatment during infancy has suppressed the virus without anti-HIV drugs for eight and a half years, scientists reported today at the 9th IAS Conference on HIV Science in Paris. This case appears to be the third reported instance of sustained HIV remission in a child after early, limited anti-HIV treatment. 

Experimental HIV Vaccine Regimen Is Well-Tolerated, Elicits Immune Responses
July 24, 2017

Results from an early-stage clinical trial called APPROACH show that an investigational HIV vaccine regimen was well-tolerated and generated immune responses against HIV in healthy adults. The APPROACH findings, as well as results expected in late 2017 from another early-stage clinical trial called TRAVERSE, will form the basis of the decision whether to move forward with a larger trial in southern Africa to evaluate vaccine safety and efficacy among women at risk of acquiring HIV.

NIH-Supported Scientists Elicit Broadly Neutralizing Antibodies to HIV in Calves
July 20, 2017

Scientists supported by the National Institutes of Health have achieved a significant step forward, eliciting broadly neutralizing antibodies (bNAbs) to HIV by immunizing calves. The findings offer insights for HIV vaccine design, and support further study of modified bovine antibodies as HIV therapeutics or prevention tools in humans, scientists reported in a paper published online today in Nature.

Monkeys Suppress HIV-Like Virus for Extended Period after Dual-Antibody Treatment
March 13, 2017

Giving monkeys two powerful anti-HIV antibodies immediately after infection with an HIV-like virus enabled the immune systems of some of the animals to control the virus long after the antibodies were gone, scientists at the National Institutes of Health and The Rockefeller University have found.  

NIH Research Helps Explain How Antibody Treatment Led to Sustained Remission of HIV-Like Virus
February 15, 2017

Scientists at the National Institutes of Health have found that the presence of the protein alpha-4 beta-7 integrin on the surface of HIV and its monkey equivalent—simian immunodeficiency virus, or SIV—may help explain why an antibody protected monkeys from SIV in previous experiments. 

NIH Launches First Large Trial of a Long-Acting Injectable Drug for HIV Prevention
December 20, 2016

The first large-scale clinical trial of a long-acting injectable drug for HIV prevention began today. The study, sponsored by the National Institutes of Health, will examine whether a long-acting form of the investigational anti-HIV drug cabotegravir injected once every 8 weeks can safely protect men and transgender women from HIV infection at least as well as the anti-HIV medication Truvada taken daily as an oral tablet.

First New HIV Vaccine Efficacy Study in Seven Years Has Begun
November 27, 2016

The first HIV vaccine efficacy study to launch anywhere in seven years is now testing whether an experimental vaccine regimen safely prevents HIV infection among South African adults. The study, called HVTN 702, involves a new version of the only HIV vaccine candidate ever shown to provide some protection against the virus. HVTN 702 aims to enroll 5,400 men and women, making it the largest and most advanced HIV vaccine clinical trial to take place in South Africa, where more than 1,000 people become infected with HIV every day. 

NIH Scientists Identify Potent Antibody that Neutralizes Nearly All HIV Strains
November 15, 2016

Scientists from the National Institutes of Health have identified an antibody from an HIV-infected person that potently neutralized 98 percent of HIV isolates tested, including 16 of 20 strains resistant to other antibodies of the same class. The remarkable breadth and potency of this antibody, named N6, make it an attractive candidate for further development to potentially treat or prevent HIV infection, say the researchers.

Antibody VRC01 Safe, Only Modest Effect in Controlling HIV Without Antiretroviral Therapy
November 9, 2016

Infusions of an anti-HIV antibody known as VRC01 were shown to be safe and maintained intended antibody concentrations in the blood of people living with HIV, according to two related studies by scientists at the National Institutes of Health (NIH) and the AIDS Clinical Trials Group (ACTG). The antibody modestly suppressed blood levels of HIV in people who stopped taking antiretroviral therapy (ART), but the delay in the reappearance of virus was not clinically significant.

Large Increases in HIV Suppression Needed to Reduce New Infections in Critical Population
October 19, 2016

Achieving moderate reduction of new HIV infections among men who have sex with men (MSM) will depend on significantly increasing the percentage of HIV-infected MSM whose viral load is suppressed to undetectable levels, according to a new mathematical model based on data from Baltimore. Access and adherence to antiretroviral therapy are key to sustained HIV suppression, which dramatically reduces the risk of transmitting HIV to others.

Women Report Vaginal Ring for Preventing HIV Had Little Effect on Sexual Intercourse
October 18, 2016

Most women who used an experimental vaginal ring for HIV prevention report that the physical act of sex was largely unaffected by using the product, which is inserted monthly for continuous wear. This finding is among several insights gleaned about experiences of women who used the ring during the ASPIRE study, also known as MTN-020, announced today at the HIV Research for Prevention (HIVR4P) meeting in Chicago.

Scientists at NIH and Emory Achieve Sustained SIV Remission in Monkeys
October 13, 2016

Scientists at the National Institutes of Health (NIH) and Emory University have experimentally induced sustained remission of SIV, the simian form of HIV, in infected monkeys. The animals’ immune systems have been suppressing the virus to undetectable levels for as long as 23 months since the monkeys completed an investigational treatment regimen. In addition, the regimen has led to the near-complete replenishment of key immune cells that SIV had destroyed, something unachievable with antiretroviral therapy (ART) alone. The findings will be published in the Oct.

NIH-Funded Scientists Identify Immunological Profiles of People Who Make Powerful HIV Antibodies
July 29, 2016

People living with HIV who naturally produce broadly neutralizing antibodies (bNAbs) that may help suppress the virus have different immunological profiles than people who do not, researchers report. While bNAbs cannot completely clear HIV infections in people who have already acquired the virus, many scientists believe a successful preventive HIV vaccine must induce bNAbs

Immune-Enhancing Treatment May Destabilize HIV Reservoirs
July 21, 2016

Although antiretroviral therapy (ART) can reduce the amount of HIV in the blood to an undetectable level in most chronically infected people, it cannot eliminate reservoirs of HIV that persist in latently infected immune cells.

NIH Scientists Discover that Defective HIV DNA Can Encode HIV-Related Proteins
July 18, 2016

Investigators from the National Institutes of Health have discovered that cells from HIV-infected people whose virus is suppressed with treatment harbor defective HIV DNA that can nevertheless be transcribed into a template for producing HIV-related proteins.

HIV Therapy for Breastfeeding Mothers Can Virtually Eliminate Transmission to Babies
July 18, 2016

For HIV-infected mothers whose immune system is in good health, taking a three-drug antiretroviral regimen during breastfeeding essentially eliminates HIV transmission by breast milk to their infants, according to results from a large clinical trial conducted in sub-Saharan Africa and India.

Vaginal Ring May Cut HIV Infection Risk if Used Consistently
July 18, 2016

A new exploratory analysis of data from the ASPIRE study has found that using a drug-infused vaginal ring most or all of the time reduced the risk of HIV infection in women by at least 56 percent. This finding is being reported today at a press briefing at the 21st International AIDS Conference (AIDS 2016) in Durban, South Africa, and will be presented in more detail tomorrow in a lecture at the conference.

NIH Expands Investment in HIV Cure Research
July 13, 2016

The National Institutes of Health has awarded approximately $30 million in annual funding over the next five years to six research collaborations working to advance basic medical science toward an HIV cure.

HIV Vaccine Research Requires Unprecedented Path
July 12, 2016

The development of an effective vaccine to prevent HIV infections would represent a critical step toward ending the HIV/AIDS pandemic. Thus far, the only large clinical trial for an HIV vaccine to show promise was the RV144 study conducted in Thailand in 2009, which resulted in a modest 31 percent reduction in infection. Researchers are working to improve on the results of RV144 and also have launched efforts to create vaccines that induce broadly neutralizing antibodies that can block a wide range of HIV variants.

NIH Statement on HIV Vaccine Awareness Day 2016
May 18, 2016

NIH-Led Team Discovers New HIV Vaccine Target
May 12, 2016

A team led by scientists at the National Institutes of Health (NIH) has reported a research trifecta. They discovered a new vulnerable site on HIV for a vaccine to target, a broadly neutralizing antibody that binds to that target site, and how the antibody stops the virus from infecting a cell.

AIDS-Kaposi’s Sarcoma Study Ended
May 5, 2016

Enrollment into a clinical trial funded by the National Institute of Allergy and Infectious Diseases (NIAID) investigating two different strategies to treat limited-stage AIDS-related Kaposi’s sarcoma was stopped due to futility—if continued, the study would be unlikely to detect a difference between the two study arms.

Single Antibody Infusions Provide Durable Protection Against HIV-Like Virus in Monkeys
April 27, 2016

A single antibody infusion can protect monkeys against infection with an HIV-like virus for up to 23 weeks, researchers have found. The study, published in Nature, was led by scientists at the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, and The Rockefeller University.

Animal Study Paints Picture of the Earliest Immune Responses to HIV
April 13, 2016

New research in monkeys exposed to SIV, the monkey equivalent of HIV, suggests that the virus spreads rapidly in the body and triggers early host responses that suppress antiviral immunity, thus promoting viral replication. The study, published in Cell, provides a detailed view of the period between initial mucosal exposure to the virus and the point at which it becomes detectable in the blood.

NIH Launches Large Clinical Trials of Antibody-Based HIV Prevention
April 7, 2016

Enrollment has begun in the first of two multinational clinical trials of an intravenously delivered investigational antibody for preventing HIV infection. Known as the AMP Studies, for antibody-mediated prevention, the trials will test whether giving people an investigational anti-HIV antibody called VRC01 as an intravenous infusion every 8 weeks is safe, tolerable and effective at preventing HIV infection.

AIDS-Kaposi’s Sarcoma Study Changed Due to Drug Underperformance
March 18, 2016

A clinical trial funded by the National Institute of Allergy and Infectious Diseases (NIAID) comparing three advanced Kaposi’s sarcoma chemotherapy regimens in combination with antiretroviral treatment (ART) for patients with AIDS will no longer enroll participants in the study arm testing the oral chemotherapy drug etoposide.

Antibodies from Unconventional B Cells Less Likely to Neutralize HIV, NIH Study Finds
March 17, 2016

Antibodies derived from a type of immune cell found in unusually high numbers in HIV-infected individuals with chronically uncontrolled virus levels are less effective at neutralizing HIV than antibodies derived from a different type of immune cell more common in people without HIV, scientists report. 

Maraviroc-Containing Regimens Safe, Tolerable When Taken for HIV Prevention
February 24, 2016

Maraviroc, an oral drug used to treat HIV infection, is safe and well-tolerated when taken daily as pre-exposure prophylaxis (PrEP) to prevent HIV infection by HIV-uninfected men who have sex with men (MSM) at increased risk for acquiring HIV.

NIH-Funded Study Finds Critical Population Adheres to PrEP with Coordinated Care
February 24, 2016

New findings suggest that black men who have sex with men (BMSM) with access to a novel coordinated care program can adhere to pre-exposure prophylaxis (PrEP), a medication regimen that helps prevent HIV infection in uninfected individuals.

Experimental Ebola Vaccines Well Tolerated, Immunogenic in Phase 2 Study
February 23, 2016
