[Verified Answer]: A patient asks

A patient asks. “Why do I need a yearly flu vaccination?” What response should the nurse provide to best address the patient’s question? “The body can’t tolerate the change required to allow for permanent protection.” “The vaccination is only effective for 10 to 12 months.” “The virus changes from year to year so the vaccine must be updated to effective.” “It’s likely that permanent protection will be available in just a few years.”
