Novel Indicator of Influenza Immunity Identified

Investigators found that people with higher levels of HA stem antibodies at the start of the study were less likely to become infected with influenza. The findings suggest that the level of HA stem antibodies can be used as an indicator, or correlate, of protection against influenza virus infection. The study provides data to support the development of novel vaccine candidates targeting the HA stem, according to the researchers. Scientists hope such vaccine candidates will induce broader and more durable protection against influenza than current vaccines. The authors note that future studies should examine the role of HA stem antibodies for various strains of influenza virus. https://www.technologynetworks.com/tn/news/novel-indicator-of-influenza-immunity-identified-320170?utm_campaign=NEWSLETTER_TN_Breaking%20Science%20News&utm_source=hs_email&utm_medium=email&utm_content=73324746&_hsenc=p2ANqtz-8_-PZ-u-FiHB5BOfx2KhPlBhUKbt8cVM_7xUjArlpI3k9V2XqiOLx8yuh7l0CZg0n7nbrzB4xj5DrnfkDBCmSujDfhew&_hsmi=73324746
