Get emergency medical help if your child has signs of an allergic reaction: hives, rash, dizziness, weakness, fast heartbeats, difficult breathing, swelling of the face, lips, tongue, or throat.

The vaccination provider may want to watch your child for a short time after the shot, to make sure your child does not have an allergic reaction. Your child will be treated quickly if there is a reaction right after receiving the vaccine.

Your child should not receive this vaccine if the first shot of COVID-19 vaccine caused an allergic reaction. The doctor or vaccination provider will determine if your child can safely receive this vaccine.
