Medical groups have issued guidelines for vaccinations. The goal is to clarify information about flu and COVID-19 shots. These groups want to help people understand the importance of getting vaccinated.

The Food and Drug Administration has approved updated versions of COVID-19 shots, which are starting to arrive. Flu vaccinations are also beginning. Further details about who should get vaccinated and when are typically provided by the Centers for Disease Control and Prevention, but more information can be found through other sources.
