Babies are born with a natural immunity or resistance to disease. It's nature's way of starting them off on the right track. Unfortunately, that natural immunity doesn't last forever. You need to have your baby immunized to protect against such diseases as measles, rubella, diphtheria, tetanus, pertussis, polio, hepatitis B and Haemophilus influenzae type b. Parents are advised to talk with their child's health care provider about which vaccines are recommended and at what ages. Changes in recommended immunizations occur each year, so it is important to talk with your child's health care provider. Keep your child's immunization record current and in a safe place, as it may be required later for childcare, military service, college or travel. For more information, call your city or county health department, or the Missouri Department of Health and Senior Services Immunization program at 573-751-6124.
