Immunization Schedule for Infants and Young Children

According to the Centers for Disease Control and Prevention (CDC), vaccine-preventable childhood diseases in the United States are near an all-time low. But, some viruses and bacteria are still active and can cause serious illness.

It is important that all children, especially infants and young children, receive recommended immunizations on time. In other countries, many vaccine-preventable diseases are relatively common. Because of travel, these diseases could return to the US, resulting in increased, and unnecessary, illness, disability, and death among children.
