We're quickly coming up on flu season and in the midst of the pandemic, getting a flu vaccine may be more important this year than in the past. Click here to see the page from the CDC on flu vaccines. Flu vaccines are available at most pharmacies as well as doctors' offices. Although the CDC doesn't recommend one vaccine over another, they do encourage people to get the vaccine early in the fall, before flu season gets underway. Remember that it takes two weeks from receiving the vaccine until it is fully activated.
