Most Americans are now eligible for the COVID vaccine and are probably also aware by now that there are a number of side effects that may be due to the shot. Fortunately, the Centers for Disease Control and Prevention (CDC) ensures that these side effects are a normal response to your body-building immunity, but they can still be unpleasant and nervous ̵
A study published in Journal of the American Academy of Dermatology on April 7 looked at 414 patients who reported one or more skin reactions after receiving an mRNA COVID vaccine between December 2020 and February 2021. The most common skin side effects included delayed major local reactions, local injection site reactions, urticaria outbreaks) and morbilliforms rash, which is a rash all over the body that looks almost like measles.
“People can get rashes all over their bodies and it can be surprising and a little scary,” Esther Freeman, MD, the study’s senior author and director of global health dermatology at Massachusetts General Hospital, told USA today. And for more vaccine guidance, this common medication may make your vaccine less effective, the study says.
As long as you experience a rash at least four hours after your vaccine, you should be fine. Any faster than that and you may experience a severe or immediate allergic reaction to the COVID vaccine, as the CDC says, should be examined immediately by a doctor. According to the study, delayed skin reactions typically start a day or so after vaccination, but can also be delayed until seven or eight days later.
“For people whose rash started four or more hours after receiving the vaccine, zero percent of them continued with anaphylaxis or other serious reactions,” Freeman explained. She added that the people who got rashes all over their bodies “did extremely well” and “recovered.”
Importantly, cutaneous allergic symptoms reported in this study, such as urticaria, angioedema and / or morbilliform outbreaks, may not be due to allergy to the vaccine, but rather related to the host immune response or an immunological response to non-steroidal anti-inflammatory drugs commonly taken. for pain and fever after vaccination, “the researchers explained in the study.

According to the study, several people experienced a rash all over their body after the first dose of the vaccine. Of the patients who reported skin reactions following the Moderna vaccine, morbilliform was the fourth most common skin reaction occurring in 11 patients after the first dose and in seven after the second. For those receiving Pfizer, morbilliform was the third most common skin reaction that occurred in six patients after the first dose and in three after the second. And for more on the different reactions between doses, doctors warn you to be “prepared” for this after your second dose.
If you experience a skin reaction – even a rash all over your body – after the first dose, do not let it deter you from the second dose. Freeman noted that those who experienced rashes throughout the body “were able to go back and get their second dose.”
“People may feel reassured about getting the second dose of their vaccine,” she said. “Even if you have a pretty impressive rash after the vaccine, as long as it did not start within four hours of the vaccination, you should feel comfortable getting the second dose.”
According to the CDC, you should only receive the second dose of COVID vaccine in a two-dose series if you have a severe allergic reaction or an immediate allergic reaction – regardless of the severity – of the first dose. “An immediate allergic reaction occurs within four hours of vaccination and may include symptoms such as hives, swelling and wheezing (difficulty breathing),” the CDC notes. And if you want more advice on vaccine reactions, you can do this after your vaccine makes side effects worse, doctors say.
