Many of these side effects will dissipate after a day or two, but exertion could make them worse.
Purvi Parikh, an immunologist and allergist with Allergy & Asthma Network, told POPSUGAR exercise increases blood flow, which could, in turn, increase inflammation.
Dr Parikh said: “Exercise should be avoided after the vaccine and can resume when feeling back to normal the next day or day after.”
She added: “The next day if you’re feeling well, you can go back to your exercise routine.”
