The correct response is: Viruses mutate to attack the vaccine molecules so new ones must be continually produced.
Viruses are known to mutate rapidly, which can affect how effective a vaccine is. This constant change necessitates the development of new vaccines or updates to existing vaccines to ensure they continue to provide protection against evolving viral strains.
