Get emergency medical help if your child has signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Keep track of any and all side effects your child has after receiving this vaccine. When the child receives a booster dose, you will need to tell the doctor if the previous shot caused any side effects.

• seizure (blackout-out or convulsions); or

• fussiness, irritability, crying for an hour or longer.

Common side effects may include:

• mild fussiness or crying;

• drowsiness; or
