Twice as many Americans die from the flu every year as die from AIDS, breast cancer, or prostate cancer. Because the flu virus changes, at least one of the vaccine's viruses must be replaced with a newer one every year, so the shot only lasts about a year. Protection develops one or two weeks after you get your flu shot. Anyone over 6 months old who wants or needs to reduce their chance of getting the flu. Between September and mid-November.
Flu vaccines contain no live virus, so it's impossible to get the flu from a flu shot.
If you do manage to get the flu, it will be a milder case if you've gotten the shot. You are invited to join our mailing list and receive monthly issues of our chapter's newsletter via E-mail.
