If vaccinated and booster, Arwady says testing likely isn't necessary several days following exposure as you likely aren't contagious. But Hay cautions there is considerable variation in the studies because of small sample sizes, differing populations, how the rapid tests are done, the vaccination status of who's being tested and how healthy they are, among other factors. But because we are still in the midst of a pandemic, it's a good idea to take a test to help rule out COVID-19 first, even if you may just be dealing with seasonal allergies.
