I have a new baby at home who isn't old enough to get a flu shot. By me getting a shot I am also protecting him to some degree.
Excellent. They call this "herd immunity" - if a sufficient number of people in a large group are immunized, then it can break the cycle of infection, providing protection to even those who do not (or cannot) get immunized. Oppositely, if enough people fail to be immunized, then a disease can make a comeback, such as whooping cough.
