National Infant Immunization Week – April 21-28, 2025

This year, National Infant Immunization Week is from April 21 to April 28 in the United States. Did you know that, in 2019, 14 million infants were not reached by vaccination services? National Infant Immunization Week is observed annually and highlights the need for protecting children of ages two years and under from vaccine-preventable diseases. 

History of National Infant Immunization Week

Every year, National Infant Immunization Week is observed to protect small children from vaccine-preventable diseases. It is essential to make sure that the families stay on track with their children’s vaccination.

The first National Infant Immunization Week (NIIW) was observed in 1994 with the support of the Center for Disease Control and Prevention. NIIW was created to increase the profile of infant immunization programs in the United States.

Immunization saves millions of lives every year but, still, there are more than 19 million under-vaccinated people. National Infant Immunization Week promotes immunization programs and increases awareness thereof.

Before, children were not protected through immunizations, which put them at risk of fatal diseases. But today, children can be protected from 14 serious diseases. Yes, the shots might hurt a little but the diseases that they protect the infants from are much more dangerous. It is better to keep your children protected from infectious diseases.
