The CDC recognizes that the best, most up-to-date health information is meaningless unless it is available to the people it is meant to serve. By working with public health and grassroots partners, and by leveraging the voices of the Internet and communication media, the CDC ensures the best health and safety information is accessible to everyone who needs it.

The National Immunization Program (NIP) is a part of the Centers for Disease Control and Prevention (CDC), located in Atlanta, Georgia. A disease-prevention program, the NIP provides leadership for the planning, coordination, and implementation of immunization activities nationwide.
