A sore arm is common with vaccination, but COVID arm is not

As COVID vaccination increases, it is important to recognize and understand the potential side effects. For the Moderna vaccine, there have been reports of skin reactions at the site of the injection. This is called “COVID arm.” This delayed reaction is different from local pain, redness, and swelling, which are common a day after either dose and last 2 to 3 days.

Instead, COVID arm usually starts 2-12 days after the first dose. It is characterized by redness, itching, swelling, and tenderness. The reaction lasts an average of 5 days, but can last up to 3 weeks. The cause appears to be a sensitivity reaction to the Moderna vaccine. Having COVID arm after the first injection does not protect against it happening again with the second dose. Treatments include steroid creams, oral antihistamines (such as allergy medicine), and cool compresses (such as an ice pack or cool washcloth).

Don’t delay the second injection

COVID arm with the Moderna vaccine is not linked to any other serious vaccine reactions. Having COVID arm after the first injection should not discourage people from having the second one.
