Vaccination with the influenza vaccine confers lifelong immunity to influenza virus.

Question

Quizplus · Accepted Answer

Vaccination with the influenza vaccine does not confer lifelong immunity to influenza virus. The influenza virus undergoes frequent mutations, which require new vaccines to be developed every year to provide protection against the most current strains of the virus. Vaccination provides immunity against these specific strains for a finite period of time, but it may not protect against new strains that emerge later.
