Immunization Information: Infants & Young Children 

Infants and children ages 0 to 6 years need immunizations (vaccines) to protect them from dangerous infectious diseases.  These diseases can cause serious complications and death in babies and children who are not

Thanks to vaccines, many infectious diseases that were once common in the United States have been controlled.  Recent outbreaks of pertussis and measles show that vaccines are still important. Today, immunized infants and children are much less likely to experience serious diseases such as polio, measles, pertussis (whooping cough), rubella, mumps, tetanus, and varicella (chicken pox).

Vaccines help prevent infectious diseases and save lives.  By immunizing on time, you can protect your baby or child and also protect others at home, school, or daycare.

Information about Individual Vaccines

Vaccine Information Statements (VISs) are information sheets produced by the Centers for Disease Control and Prevention (CDC). VISs explain both the benefits and risks of a vaccine. Prior to vaccine administration, a VIS must be provided for all vaccines identified by Federal law.

The most up-to-date collection of VISs is available at:

Vaccine Safety

Research has demonstrated that the childhood vaccine schedule and combination of vaccines are safe and effective.  Vaccines are held to the highest standard of safety.  The United States currently has the safest, most effective vaccine supply in history.  There is no scientific evidence that childhood immunizations cause autism or that giving multiple shots can harm or “overload” the immune system of infants or children.  Side effects can occur with any medicine, including vaccines.  Slight discomfort (such as pain at the injection site) is a common, non-serious side effect.  Serious reactions to vaccines are very rare.  Anyone who receives a vaccine should be informed about both the benefits and risks of vaccination.  More information on vaccine safety is available at:

If your child has a reaction following a vaccination, you can report it to a national vaccine safety surveillance program—the Vaccine Adverse Event Reporting System (VAERS):

Thinking about Waiting to Vaccinate or Not Vaccinating?

Parents who choose not to vaccinate their children on time increase the risk of disease and death not only for their children, but also for other children and adults throughout the entire community. 

Any questions or concerns should be discussed with a health care provider.
