The National Immunization Program is a government-led initiative that aims to promote vaccination and make vaccines accessible to everyone in the United States. The program is responsible for developing and implementing policies related to vaccine administration, conducting research on vaccine efficacy and safety, and coordinating with health care providers to ensure the availability and appropriate administration of vaccines.

Through this program, millions of people have been protected from serious diseases such as measles, polio and influenza. Vaccines are considered one of the most effective public health interventions available, and the National Immunization Program plays an important role in ensuring everyone has access to these life-saving tools.
