Hepatitis B and C—A Closer Look at NIAID Research to Accelerate Elimination
Viral hepatitis is an inflammatory liver disease caused by infection with any of the known hepatitis viruses—A, B, C, D, and E. Most of the global viral hepatitis burden is from hepatitis B and C, which affect 354 million people and result in 1.1 million deaths annually. The Centers for Disease Control and Prevention estimates that in 2020 there were 14,000 and 50,300 new acute infections of...

Assessment of PrEP Eligibility Tool Among the General Population in Uganda
To reduce the spread of HIV infection, the World Health Organization (WHO) recommends pre-exposure prophylaxis (PrEP) in populations with an annual HIV infection incidence greater than 3%. Given that the annual HIV incidence in Uganda is estimated at 0.40% (0.46% among females and 0.35% among males), there are people who may have a higher HIV risk and may benefit from PrEP but are not targeted for...

Maternal HIV Drug Resistance Is Associated with Mother-to-Child Transmission
Antiretroviral therapy of pregnant women and antiretroviral treatment of infants have greatly reduced the rate of mother-to-child HIV transmission, also referred to as vertical transmission. Nevertheless, although these improved rates have occurred in some countries, vertical transmission rates remain relatively high in others. This may be due to multiple factors, including access to testing, care...
The 2001 International Maternal Pediatric Adolescent AIDS Clinical Trial Network (IMPAACT) Study on Rifapentine and Isoniazid for Tuberculosis Prevention in Pregnant Women
Tuberculosis (TB) has a significant impact on maternal and infant health and is one of the leading causes of maternal death worldwide. Pregnant and postpartum women with latent TB are at a higher risk of developing active TB and pregnancy complications due to TB infection can result in babies with low birth weight, premature birth, and stillbirth. Additionally, maternal TB more than doubles the...
Two HIV Treatment Drugs Tested in Pregnant and Postpartum Women with HIV
For pregnant women living with HIV, antiretroviral treatment (ART) is recommended to treat the infection in the mother and prevent mother-to-child HIV transmission. However, pregnancy may affect the way antiretroviral drugs are metabolized and may result in rendering the drug less effective. Studies that address the pharmacokinetics (rates of distribution, absorption, metabolism, and excretion) of...
NIAID Observes HIV Vaccine Awareness Day 2021
While implementation of highly effective HIV treatment and prevention tools has reduced the HIV pandemic worldwide, development of a safe and even modestly effective vaccine would hasten progress toward a durable end of the HIV pandemic. Today, on HIV Vaccine Awareness Day, NIAID acknowledges both the progress that has been made in HIV vaccine development and the challenges that remain. We also reflect on how advances in HIV vaccinology paved the way for COVID-19 vaccine development.
Efficacy and Safety of Three Different ART Regimens during Pregnancy
Viral suppression of HIV during pregnancy is important for both maternal health and prevention of mother-to-child transmission. Antiretroviral therapy (ART) is an effective method to manage HIV, but rigorous studies on the safety and efficacy of different ART regimens in pregnant women have been limited. To address this, a recent phase 3 trial was conducted to compare three ART regimens...

HIV Prevention Study Conducted in Different Geographic Regions Among At-risk Women, Men, and Transgender People
Although the spread of HIV has slowed down thanks to risk-reduction measures, prevention efforts, and oral antiretroviral preexposure prophylaxis (PrEP), there are more than 1.5 million new cases of the human immunodeficiency virus (HIV) each year worldwide. The Antibody Mediated Prevention trials included two clinical trial cohorts, to test the ability of the monoclonal antibody VRC01 to prevent...

Lower Incidence of HIV Infection among Women in Epidemic Settings with Initiation and Flexible Access to PrEP
Despite major advances in testing and treating HIV, including highly effective oral pre-exposure prophylaxis, there were 1.7 million new cases of HIV in 2019. Fifty-nine percent of these occurred in sub-Saharan Africa, where a high proportion of newly infected individuals are women. In order to see if facilitating PrEP delivery decreased HIV transmission in these areas, a flexible care delivery...
