Time for My Booster Shot Dr. Francis Collins 2 years ago I got my booster shot last week. The process was extremely quick and easy, and I felt great afterwards. I received my first dose of the Moderna vaccine in December 2020 and the second dose in January 2021. So, it was definitely time for me to get my Moderna booster. If you haven’t already, please consider getting a COVID-19 booster shot to protect your health entering the winter holiday season. Credit: NIH Share this:
