How the COVID-19 Vaccine Affects Acne Cortisone Shots
Cortisone shots are administered by dermatologists to help heal deep, cystic pimples, reduce swelling, and speed up the recovery process of the zit. Though the risk of getting a cortisone shot around the same time as your COVID-19 vaccine is very small, there's still one thing to consider.
"A potential problem with getting a cortisone shot in a pimple around the time you are getting your COVID-19 vaccine is a decreased immune response, which could reduce vaccine efficacy," Anna Karp, DO, board-certified dermatologist at the Skin Institute of New York Dermatology, told POPSUGAR.
Again, this is a minor risk because only a very small amount of cortisone is typically injected into pimples, but if you want to be extra cautious, Dr. Karp recommended waiting "at least a week before and a week after" getting vaccinated before doing a steroid injection.
