Jan 17, 2019 The CDC recommends vaccination for the flu through January or even later. We can expect the flu to stick around through February and into March of this year, meaning there’s still time for anyone who hasn’t gotten vaccinated yet to do so — though ideally, do so sooner rather than later, since it takes about two weeks to build up immunity following your shot. The CDC last week also released mid-season estimates of the flu’s toll, the first time the agency has done so while the season is still underway. So far, about 6 to 7 million people have come down with the flu, and approximately 70,000 to 80,000 people have been hospitalized since October. The Faculty and Staff Clinic still has flu shots available so please call us at 256-824-2100 to get your shot!
