According to the CDC, high levels of flu activity are expected to continue for the next several weeks. So if you haven't gotten your vaccination yet, get one now.
A lot of people don't know this, but even though flu season is already underway, you should still get that vaccine if you haven't done it yet. As long as the virus is circulating, the CDC recommends you go get the shot. Flu season is unpredictable, but it could last until May and it takes two to three weeks for the antibodies to build up in your system to protect you.
