The immunological response to influenza vaccine and/or natural infection is evaluated by serological techniques, the most common being hemagglutination inhibition (HI), single radial hemolysis (SRH), and virus neutralization assays, which is commonly used in a micro‐neutralization (MN) format. ELISA is not officially required; however, this assay is able to measure different class‐specific antibodies. The four assays identify different sets or subsets of antibodies.
