What if my baby doesn't get shots when he or she should?

If your baby has missed a shot in a series (such as the DTaP vaccine) because of illness or another reason, don't worry. Your doctor will continue to administer the series by picking up where you left off, usually at the next well-child checkup. Some doctors will have you schedule an in-between visit with a nurse for shots to catch up. (The doctor's office keeps careful records, but it's also a good idea for you to do the same.) Be sure to remind your doctor of any missed shots.

Are there times when my baby shouldn't get a shot?

Yes, although most of the time when your baby has a low fever or a mild cold, it's still safe and effective for him or her to get the vaccine. Get your doctor's advice if your baby has:

• A high fever or a new illness.
• An immune disorder or deficiency or takes medicine that interferes with his or her immune system.
• Epilepsy.
• Had nonfebrile convulsions.
• Been given high doses of oral steroids for more than two weeks in the past three months.
• Had a severe reaction to a previous shot, such as a temperature of 105 degrees Fahrenheit (40.5 degrees Celsius) or higher, convulsions, inconsolable crying, or collapse.

What if my baby was born prematurely?

Premature babies and babies with a low birth weight (less than 5 pounds, 8 ounces or 2.5 kilograms) should follow the same schedule for immunizations as full-term infants, unless your doctor suggests otherwise.
