But Dr. Barron says we need to think about more than our personal risks. and last updated 2021-05-14 13:31:30-04 COLORADO SPRINGS â Earlier this week - on Wednesday May 12 th - I was able to speak with Dr. Michelle Barron, the senior medical director of infection prevention at UCHealth, about vaccine dosing and how a vaccine works differently in the body than medication. I also happened to ask Dr. Barron her thoughts about wearing a mask, or not wearing a mask, after someone is vaccinated, from a strictly medical perspective.
