What's a Normal Reaction to a Shot?

I had two shots yesterday and now the places around where the vaccine was injected are swollen and itchy. Am I OK?

It's very common to have some redness, tenderness, and swelling in the area where you had a shot. This kind of reaction should get better in a day or so. If you notice it getting worse, see your doctor.
