Are there any age related issues with getting the flu shot? I have heard that in some people it can actually make you sicker. My parents are in their late seventies.
Yes, it is important to get the flu shot at this time. (the flu peaks between Jan and March). If your parents do not have a true allergy to eggs, or had Guillan-Barre Syndrome , then there should not be a problem of the getting their flu shots.
