COVID ARM: A NEWLY REPORTED DELAYED REACTION RASH
Common reactions after receiving the Moderna vaccine include injection site soreness, general fatigue and headache. These symptoms usually resolved within 2 to 3 days.
A delayed reaction that appears as a red, often times bumpy rash on the arm of people who have received the Moderna COVID-19 vaccine has recently been reported in the NEJM. This bumpy rash may be limited to the arm or extend onto the torso. This reaction is occurring near the injection site 4 to 11 days after the first dose and after the initial local and systemic symptoms associated with vaccination have resolved.
Exactly why this is occurring with the Moderna vaccine is uncertain and experts say it is certainly NOT a reason to avoid getting vaccinated, with the Moderna vaccine or any other COVID vaccine approved for emergency use, for that matter.
Several patients who have experienced this rash have been successfully treated with over-the-counter anti-histamines, topical and oral corticosteroids.
