Get an Annual Flu Vaccination
There is a highly recommended flu vaccination that should be taken at least every year. The predominant circulating flu virus changes from year to year, so you’ll need to update your vaccination each year. Your doctor will tell you that it takes about two weeks for the vaccine to be effective. If you get the flu after a vaccination, the shot may reduce the severity and duration of your illness.
Due to the high risk of complications in people over the age of 65, you should get your flu vaccination early in the season, at least by late October. Talk to your doctor about getting a high-dose or adjuvant vaccine [4] (Fluzone or FLUAD). Both are designed specifically for people ages 65 and older.
A high-dose vaccine contains about four times the amount of antigen as a regular flu shot. An adjuvant vaccine contains a chemical that stimulates the immune system. These shots are able to build a stronger immune response to vaccination. In addition to getting your annual flu shot, ask your doctor about the pneumococcal vaccinations. These protect against pneumonia [5], meningitis [6], and other bloodstream infections.
