You Can Get the Flu from a Flu Shot
Vaccinations are misunderstood because they're created from the offending viruses themselves. But when you get a flu shot, you're not being injected with a whole virus -- you're receiving an inactivated, or dead, virus. That means the part of the virus that can infect you and make you sick is turned off, but the part of the virus that stimulates your body to create antibodies is still on. The body's antibodies will kill the flu virus should you come into contact with it later. Even pregnant women are advised to get flu vaccinations, so you know they're safe. The only people who should avoid them are those who have severe allergies to eggs, because eggs are used to create the vaccines. No vaccine is 100-percent effective, so there is still a chance you can get the flu after receiving the shot, but that doesn't mean the vaccination gave it to you.
