COVID-19 Vaccine

Vaccines help your body build up the ability to fight off a virus. A vaccine may not prevent you from getting the COVID-19 virus. But if you do get it, the vaccination may keep you from becoming seriously ill. Or it may keep you from developing complications due to the illness.


Community Education

Due to the overwhelmingly positive response to Mayo Clinic Health System's community forum on Sept. 10, we will welcome back Greg Poland, M.D., director of the Mayo Clinic Vaccine Research Center for a Q&A session.

Dr. Poland is a leading voice on the scientific evidence supporting the benefit of COVID-19 vaccines. He has been closely involved in vaccine decision-making at the federal level, and he is a much sought-after speaker on the many complicated issues in play during the COVID-19 pandemic. He will answer your questions about boosters, variants, vaccines for kids, and COVID-19 myths and truths.

Register in advance. After registering, you will receive a confirmation email containing a Zoom link. You should check your junk mail if you don't receive this email.
