How Do Public Health Strategies Address Antigenic Variability?

Public health strategies to address antigenic variability involve continuous surveillance, vaccine development, and antiviral drug use. Surveillance programs monitor circulating strains of pathogens to detect changes in antigenicity. This information is crucial for updating vaccines and informing public health responses. Additionally, antiviral drugs can be used to reduce the burden of disease, although the emergence of drug resistance due to antigenic variability remains a concern.
