I'm sold! Is it too late to get the vaccine?

In one word: no. Keep in mind that it takes about two weeks for antibodies to develop in your body and provide protection against the virus, the CDC says.

How can I avoid getting the flu in the first place?

It's disturbing to think about, but flu germs can spread up to 6 feet through coughs and sneezes. They can also live on surfaces for up to eight hours.

Dr. Jennifer Shu, a pediatrician and mother of two, recommends practicing good "social distancing." This means canceling parties or dates if someone is sick and avoiding large crowds (like at the movies or going out to dinner) if your community has been hit hard by the virus.

It's also a good idea to practice proper hand-washing -- for at least 20 seconds several times a day. And wiping handles, counters and remotes daily with hot soapy water or disinfectant will kill any germs that linger.
