Q: What are the normal side effects of the Moderna vaccine?

A: From the Washington state Department of Health website: “Like some routine vaccines, the most common side effects are a sore arm, tiredness, headache, and muscle pain. These symptoms are a sign that the vaccine is prompting an immune response.

“For most people, these side effects occurred within two days of getting the vaccine and lasted about a day. Side effects were more common after the second dose than the first dose.

“You may see some rumors about untrue side effects online or on social media. Make sure any time you see a claim about a side effect that you check the source of that claim. This video can teach you more about how to figure out if a claim online is true or not.”
