Monitoring the antigenic drift of viruses in global populations is essential for optimal selection of component strains for the annually updated trivalent influenza vaccine. (cdc.gov)
Depends on the match of the strains in the vaccine with circulating strains, the age of the individual and whether they have any underlying medical conditions. (health.govt.nz)
However, due to antigenic drift in influenza viruses, vaccines need to be updated every year to protect against the circulating strains of the virus. (researchsquare.com)
Antigenic drift involves small mutations in the genes of influenza viruses that lead to changes in HA and NA that accumulate over time, resulting in the emergence of novel strains that the human immune system may not recognize. (cdc.gov)
These novel strains are the influenza virus's evolutionary adaptations to a strong population-wide immune response. (cdc.gov)
