National Infant Immunization Week (NIIW) is an annual observance to highlight the importance of protecting infants from vaccine-preventable diseases and celebrate the achievements of immunization programs and their partners in promoting healthy communities.

Since 1994, hundreds of communities across the United States have joined together to celebrate the critical role vaccination plays in protecting our children, communities, and public health.

NIIW 2018 is April 21-28, 2018.
