No wonder we're all a little baffled. But swine flu isn't that hard to understand; it's a lot like seasonal flu. It has similar symptoms, such as fever, cough, sore throat, stuffy nose, body aches, headache, chills, and fatigue. As a matter of fact, it's hard to tell swine flu from seasonal flu without a lab test. To learn more about...

Flu viruses change from year to year. So each year, manufacturers develop a new vaccine based on predictions of what strains of influenza viruses will be around during flu season. In the spring of 2009, the H1N1 virus spread to the U.S. too late to be included in the regular “seasonal vaccine.” So a separate vaccine - the H1N1 flu vaccine -- was developed.

Flu Vaccines: Shots and Mists

The best way to protect yourself against the flu is to get vaccinated, say the experts at the CDC. That means getting a flu shot or the nasal-spray flu vaccine, preferably between October and November.

Flu Shots FAQ

Won't the flu vaccine make me sick?
Have no fear, getting vaccinated against the flu won't give you influenza. The flu shot is made of killed virus; the mist is made of live, but weakened virus. Both vaccines may produce mild symptoms like muscle aches and a runny nose, but these symptoms are brief and far less severe than the actual flu itself.

I'm pregnant. Should I get the flu shot?
Pregnant women can be particularly vulnerable to flu complications, which include pneumonia, hospitalization, and death.

If you'll be pregnant during flu season, the CDC recommends getting vaccinated. The nasal spray flu vaccine is not recommended for pregnant women.
