Influenza vaccination is one of the most effective public health tools to reduce the burden of seasonal flu outbreaks, protect vulnerable populations, and prevent healthcare system overload.
The influenza virus is classified into types A, B, C, and D, with types A and B causing most human illnesses. Because of frequent genetic mutations in the virus — a phenomenon known as "antigenic drift" — the flu vaccine must be reformulated every year to match the circulating strains. The World Health Organization (WHO) collaborates with research centers worldwide to monitor flu activity and recommend the most appropriate strains for inclusion…
