NIAID Director Anthony S. Fauci, M.D., gets a seasonal influenza vaccine every year. In a new video, he explains why getting the flu shot is so important for individual health and to prevent the spread of influenza virus. Dr. Fauci also discusses other tips for avoiding the flu this winter, such as staying away from crowded areas and washing hands frequently.

Women tend to have greater immune responses to influenza (flu) vaccines than men, and younger people tend to have stronger immune responses to vaccines than the elderly. Previous studies have linked levels of the sex steroid hormones estrogen and testosterone to altered immune function that occurs with age.

See new infographics from the Centers of Excellences for Influenza Research and Surveillance (CEIRS) network. NIAID established the CEIRS network in 2007 to continue and expand the fight against emerging and developing strains of flu. CEIRS now helps provide information and public health tools to control the threats of both epidemic and pandemic influenza.

The seasonal influenza (flu) vaccine is recommended for all pregnant women to protect them and their newborn infants from illness. It also reduces the risk of pregnancy complications such as premature birth and low birthweight that can result in short- and long-term health problems for the child.

Differences in disease severity between females and males have been described for several pulmonary (lung) infections, including influenza (flu). In influenza infections, studies have shown that females have more inflammation in the lungs and overall have a more severe outcome compared to males, despite having comparable levels of flu virus in the body. This suggests that the worse outcome in females may result from an inability to resolve inflammation rather than a failure in controlling viral replication.

Pregnant women are known to be more susceptible to infectious and non-infectious respiratory disease compared to non-pregnant women. Infection with influenza A (flu) viruses (IAV) in pregnant women results in more severe disease, especially in the third trimester of pregnancy, when pregnant women are more likely to be hospitalized and twice as likely to die from influenza-associated disease. Pregnancy is known to induce both anatomic and functional changes in pulmonary (lung) physiology, but little is known about how these changes affect the course of respiratory diseases.

Estrogens are reproductive hormones that influence a range of processes in both females and males. Estriol (E3), one of three forms of estrogen that females produce, has wide-ranging activity in diverse tissue types. Because E3 has relatively weak effects on breast and uterine tissues, treating women with E3 is associated with a lower risk of breast and uterine cancer compared with other forms of estrogen. E3 also has anti-inflammatory effects and can reduce the severity of autoimmune diseases such as multiple sclerosis.

A person’s sex has been shown to affect immune responses, including the response to both influenza virus infection and vaccination. Women have consistently stronger immune responses compared with men, including higher antibody responses to viruses like influenza, hepatitis B, herpes virus, and others.

Curious about where challenge trials take place on the NIH campus? Dr. Matthew Memoli led a livestreamed “virtual tour” of the Special Clinical Studies Unit, where Ebola patients were cared for and where participants in challenge trials of influenza, RSV, and other pathogens stay while they are infectious.

Could an influenza virus like the one which caused the 1918 pandemic emerge today? If it did, could we stop it? In a short video, NIAID experts discuss how seasonal and pandemic influenzas change over time, and how researchers are working to improve influenza vaccines.
October 30, 2018
In this short video, NIAID experts describe why the 1918 influenza was the most deadly pandemic in all recorded history, and how scientists are still studying it today.

Video: NIAID scientist Dr. Jeffery Taubenberger talks about his research on 1918 flu.

The annual NIH Research Festival showcases research by scientists who work in the 27 Institutes and Centers of the National Institutes of Health. This year’s event featured talks by NIAID’s Director, Anthony S. Fauci, M.D., and four of our intramural researchers.

Each year, NIAID-funded scientists visit the beaches of Delaware Bay to test shorebirds for avian flu viruses. A video from NIAID Now profiles their work.

Dr. David M. Morens delivered the 2018 John R. LaMontagne Memorial Lecture about the deadliest pandemic of all time.

NIAID makes many resources available to researchers, such as reagents, model organisms, and tissue samples. Now it’s even easier to find these resources on our site using the Resources for Researchers feature.

A new study suggests that influenza infection may enhance some white blood cells’ ability to defend against secondary bacterial infections.
Feeling Fluish: Large International Trial Compares Multidrug and Single Drug Treatments for Influenza
September 27, 2017
The fever, fatigue, muscle and headache caused by influenza (flu) can make even the healthiest person feel miserable for days. For more vulnerable people, such as the very young or the elderly, flu can be fatal. Although vaccination is recommended and can help protect against flu infection, there is a need for effective therapies to combat illness caused by the flu virus.
August 25, 2017
In a new study, researchers describe immune profiles measured prior to vaccination that may predict a person’s antibody response to the seasonal flu vaccine. Their findings also indicate that immune states that predict good vaccine responses in young adults may be associated with poorer responses in older people.

Each May, NIAID-funded researchers descend on the beaches of Delaware Bay in New Jersey to screen migratory shorebirds for the flu. Through this work, they are learning more about how influenza viruses spread and evolve.
