Getting COVID-19 can cause all manner of odd skin reactions. A new study finds some of them, including COVID toes, a measles-like rash and shingles also can be rare, and thankfully brief, side effects of getting the Pfizer-BioNTech or Moderna vaccines.

The minor, though sometimes itchy and annoying, reactions were seen in a database of 414 cases of delayed skin problems linked to the vaccines and reported to health care professionals. The cases were collected between December and February before the Johnson & Johnson vaccine had been authorized, so it was not included.

None caused a life-threatening reaction, a finding the study's senior author Dr. Esther Freeman found reassuring.

“People can get full-body rashes, and that can be surprising and a little scary, but these patients did extremely well, recovered and were able to go back and get their second dose,” said Freeman, director of global health dermatology at Massachusetts General Hospital.
