Cases of ‘COVID arm’ following vaccination being documented by dermatologists

Some COVID-19 vaccine recipients may develop swollen, red patches at the injection site

Cases of so-called "COVID arm" are seemingly on the rise, with some experiencing red, swollen skin days after receiving the COVID-19 vaccine.

The American Academy of Dermatology Association has opened a registry for health care providers to report such reactions in their patients in an effort to better understand the "dermatologic manifestations" of the coronavirus vaccine, they said.

Dr. Elizabeth Houshmand, a board-certified dermatologist in Texas, told local news station KXAS-TV that the swollen, red patches some may see on their arm days after receiving the vaccine indicate a "mounting immune response." 

"It's uncomfortable but I wouldn’t let it stop you from getting the vaccine," she said.

On its website, the Centers for Disease Control and Prevention (CDC) states that common side effects of the COVID-19 vaccine include pain and swelling at the injection site. Some may also experience fever, chills, fatigue, or a headache.

Those who experience an increase of redness or tenderness at the injection site  24 hours after receiving the vaccine or have any "worrying" side effects that don’t subside after a few days should speak to their doctor, the CDC says.
