Jul 28, 2023 · Respiratory viruses like influenza virus (flu), SARS-CoV-2 (which causes COVID) and respiratory syncytial virus (RSV) can make us sick by infecting our respiratory system, including the nose,...

Jan 23, 2018 · Scientists only recently discovered that humans naturally generate anti-HA stem antibodies in response to flu infection, and this is the first study of its kind to evaluate pre-existing levels of these specific antibodies as a predictor of protection against influenza.
Immune responses to natural infection with influenza virus in humans are relatively broad and long-lived, but influenza viruses can escape from these responses over time owing to their high mutation rates and antigenic flexibility.
