The CDC on Thursday reported that the 2012 flu vaccine is 62 percent effective -- meaning that nearly 40 percent of people who got the flu shot will still wind up getting sick.

It turns out, however, that the 62 percent rate falls right in the middle of expected effectiveness for flu vaccines, which the CDC says traditionally is in the 50 percent to 70 percent range.

Still, the CDC recommends a flu shot for everyone over the age of six months.

Seasonal flu vaccines are designed to protect against the three influenza viruses. The viruses are selected based on international surveillance and scientists estimations about which types and strains of viruses will circulate in a given year.

The vaccine won't fully protect you until 2 weeks after vaccination, when antibodies that provide protection against the influenza viruses in the vaccine have developed in the body.

Still looking to get a shot, here's a website that shows you where to go.
