You Won’t Catch the Flu From a Flu Shot
Contrary to popular belief, you can’t get the flu from the flu shot. Influenza viruses cause the flu. And the flu shot is made with an influenza virus that has been killed or inactivated so that it can’t possibly cause the disease. Some people think they have the flu after getting the shot because they feel under the weather for a few days. They are experiencing side effects of the vaccine, like a headache or low fever that disappear after a day or two.
By comparison, the flu will make you absolutely miserable for days or weeks. While the flu might not seem like a big deal, it kills around 400,000 people each year and hospitalizes millions. Vaccination reduces your risk of getting the flu and the severity of your illness if you do get sick. Even if you’re not at high risk of getting seriously ill from the flu, chances are that someone you care about is. The flu shot protects you and young children and people who are elderly, pregnant, or immunocompromised people.
