Prevent the Flu: Boost Your Immune System

Do Lifestyle Changes Help? continued...

Exercise also helps your immune system perform at a high level.

These tactics alsobump up your levels of IgA, a protein in your immune system that fights infections. It helps keep threats out of your body -- and zaps any that do get in.

Finally, make good hygiene a habit. Nothing beats the power of frequent hand washing to keep germs at bay. Wash them for as long as it takes you to sing “Happy Birthday” twice.

What Vaccines Should I Get?

Almost all adults and children should get a pneumonia vaccine and a flu shot, especially seniors and anyone whose immune system is weakened by a disease like HIV or cancer. Babies under 6 months don’t get one.

Update your tetanus vaccine once every 10 years. If you have a high-risk job (like hospital worker) get vaccines for hepatitis A and B.

Children and teens need these:

The CDC says all children ages 11 to 12 need a vaccine for meningitis with a booster at ages 16 to 18. Also get one if you’re traveling to countries with high rates of meningococcal disease.
