COVID arm describes the redness and swelling, sometimes over a large area, that can affect the arm where the vaccine has been injected after receiving an mRNA vaccine. If these reactions occur around the injection site, in most cases it’s a week or so after the vaccination. They have been observed more frequently after vaccination with the Moderna vaccine. According to the latest findings, these reactions occur in around 8 in 1,000 people after the first dose of vaccine. They occur in around 2 out of 1,000 vaccinated people after the second dose.
If the reactions occur after the first dose of vaccine, there is no reason not to have the second dose. Neither does it mean that you will also experience the reaction with the second dose. It’s important to have the second vaccination. Only then are you as well protected as possible from the coronavirus. If you experience reactions after the first dose, it’s probably best to have the second dose of vaccine injected into your other arm.
