The correct answer is: They should get the flu vaccine because viruses mutate.
Doctors recommend people get the flu vaccine every year rather than every few years because viruses that cause the flu can mutate. Influenza viruses constantly change and evolve, resulting in new strains of the virus emerging each year. The flu vaccine is designed to protect against the specific strains of the virus that are expected to circulate in a given flu season. By getting vaccinated annually, individuals can ensure they have protection against the most current and potentially dangerous strains of the flu.
