New Vaccine Side Effect "COVID Arm" Striking Patients, Say Doctors
While the COVID-19 vaccine has been deemed safe and effective by the CDC and FDA, there are a few side effects being reported by those who have already been injected. One of them? COVID arm, which seems to be attracting a lot of attention, likely due to its dramatic sounding nature. What is it exactly and how concerned should you be about the scary sounding symptom? Eat This, Not That! asked Yale Medicine dermatologist and assistant professor at Yale School of Medicine Alicia Little, MD, Ph.D. to reveal everything there is to know about it. Read on to learn about COVID arm—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had Coronavirus.
What Is COVID Arm?
COVID arm, which should be more accurately referred to as "COVID vaccine arm" per Dr. Little, is a delayed hypersensitivity reaction to a component of the COVID vaccine. "It is a red, sometimes itchy or tender localized reaction near the vaccine injection site that occurs most frequently about 7 days after the vaccine, though it can occur as late as two weeks post-vaccine," she explains. It usually lasts around fives days, though sometimes it may last a shorter or longer time, and most reports have been in response to the Moderna COVID vaccine.
Why Does it Happen?
Dr. Little explains that COVID arm is an immune reaction to a component of the vaccine. However, experts still aren't sure which component it is reacting to. "The reaction is most likely caused by the T-cells in the immune system, which may take several days to initially get activated, but can respond to the same trigger more quickly the second time around," she says. Because vaccines are supposed to activate the immune system, "it's possible the condition may be related to the immune response we are trying to generate to the COVID spike protein, or it may be an immune response that is not directly related to developing immunity to COVID," she continues.
What Should You Do If You Experience COVID Arm?
Per Dr. Little, COVID vaccine arm is NOT something to be worried about. "People who experience COVID arm can and should get their second dose of vaccine," she affirms. However, it may help to get the second dose in the opposite arm, and if the rash is very itchy or tender, it may help to use topical steroids like hydrocortisone or to speak with your doctor.
When COVID Arm Occurs
And, Dr. Little notes that of her patients, at least half of the people who had COVID vaccine arm to the first vaccine dose get it again the second time, "but the second COVID vaccine arm reaction usually occurs sooner than the first reaction and lasts a shorter period of time," she says."Importantly, this reaction is not a sign of a worrisome allergy and it is not a reason to not get your second vaccine dose," she reminds.
What to Do if You Get COVID Arm and Other Side Effects
