The correct answer is: "They should get the flu vaccine because viruses mutate."
Viruses, including the flu virus, are constantly evolving and mutating. This means that the strains of the virus circulating in one year may be different from those in the next year. As a result, the flu vaccine needs to be updated annually to provide protection against the most current strains of the virus. Getting the flu vaccine every year helps ensure that individuals have the best possible protection against the flu.
