National Infant Immunization Week
National Infant Immunization Week (NIIW) is April 27 - May 4, 2019. NIIW is an annual observance to highlight the importance of protecting infants from vaccine-preventable diseases and to celebrate the achievements of immunization programs and their partners in promoting healthy communities.
In 2019, we are celebrating the 25th anniversary of NIIW. Since 1994, hundreds of communities across the United States have joined to celebrate the critical role vaccination plays in protecting our children, communities, and public health.
