Getting a Flu Vaccination

Flu Facts The flu vaccine will not give you the flu. The flu is caused by a virus. It can’t be treated with antibiotics. The flu can be life-threatening, especially for people in high-risk groups. About 36,000 people die of complications from the flu each year. Influenza is not the same as “stomach flu,” the 24-hour bug that causes vomiting and diarrhea. This is most likely due to a GI (gastrointestinal) infection—not the flu.

Flu Symptoms

Flu symptoms tend to come on quickly. Fever, headache, fatigue, cough, sore throat, runny nose, and muscle aches are symptoms of the flu. Children may have upset stomach or vomiting, but adults usually don’t. Some symptoms, such as fatigue and cough, can last a few weeks.

How a Flu Vaccine Protects You

There are many strains (types) of flu viruses. Medical experts predict which 3 strains are most likely to make people sick each year. Flu vaccines are made from these strains. With the shot, inactivated (“killed”) flu viruses are injected into your body. With the nasal spray, live and weakened viruses are sprayed into your nose. The viruses in both vaccines cannot make you sick. But they do prompt the body to make antibodies to fight these flu strains. If you’re exposed to the same strains later in the flu season, the antibodies will fight off the virus. Your healthcare provider can tell you which type of flu vaccine is right for you.

Who Should Get the Flu Vaccination?

Almost anyone can (and should) get vaccinated, especially people in the following high-risk groups:
