Can you train before the COVID vaccine?

Amina Abdeldaim, MD, MPH, medical director of the Picnic Allergy Treatment brand and a clinical assistant professor at the NYU Grossman School of Medicine, told POPSUGAR that if you have had a severe allergic reaction (anaphylaxis) in the past, it would be a good idea to ” put low “before your vaccine, which means” you may not have to push it with exercise. ” This is because exercise (as well as alcohol) increases your blood flow and potentially lowers your threshold for an allergic reaction. Exercise, she noted, “dilates the blood vessels in your body, leading to more allergens entering your body.” This is the same reason why some experts warn against exercising right after the vaccine.

The bottom line, however, is that severe allergic reactions are rare (anaphylaxis will typically occur within 15 to 30 minutes, and non-severe immediate allergic reactions – with symptoms such as hives, swelling and wheezing – may occur up to four hours post-vaccination) . Training before the COVID-19 vaccine should be fine, said Purvi Parikh, MD, an immunologist and allergist with the Allergy & Asthma Network. Dr. Abdeldaim agreed, and Sofija Volertas, MD, assistant professor in the UNC’s Department of Rheumatology, Allergy and Immunology, added that allergists do not have a definitive answer that someone is 100 percent ready to develop pre-vaccine.

For people who want to exercise pre-vaccination because they think it will boost their immune response, it will not necessarily do so. We know that there is some evidence that staying active overtime can benefit this answer when we talk about other vaccines. A small study published last year showed evidence of higher antibody and immune cell levels in elite athletes after flu shots compared to other healthy young people, although no “boost” was found from exercise two hours before the vaccine in a follow-up study. . Verywell points out that there are no specific data on how exercise may affect the immune response specifically to the COVID-19 vaccine.

Apart from the COVID-19 vaccine, there are some cases where allergists recommend that people not exercise before certain injections. This is the case, Dr. Volertas for POPSUGAR, for those who get allergic shots. By an abundance of caution, these people are told to “avoid having substantial exercise two to three hours before or after because we give them something we know they are allergic to.”

So you can have a sweating session before your COVID-19 vaccine, but if you are in doubt – especially if you have had anaphylaxis before – contact your doctor to see what they recommend in terms of exercise. (Note: The CDC recommends that those who have previously had severe allergic reactions, other than immediate allergic reactions to other vaccines, still be vaccinated.)
