Why Are New Flu Vaccinations Required for Each New Flu

question 60

Multiple Choice

Why are new flu vaccinations required for each new flu season instead of developing a universal flu vaccine?

• A) The vaccination cannot contain enough preservatives to last in the body longer than a year.
• B) The flu virus mutates frequently enough that last year's vaccination will no longer target currently circulating flu strains.
• C) The flu virus can become latent, meaning it can hide from the immune system within the body, so new vaccinations are important to allow for continuing immunity.
• D) The vaccination does not contain enough antigens to create a lasting immune response, so boosters are required every year.
