National Infant Immunization Week (NIIW) is April 21 through 28. It's 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.
According to the Centers for Disease Control and Prevention, vaccines are among the most successful and cost-effective public health tools available for preventing disease and death. When CDC established NIIW in 1994, immunization programs were facing significant challenges. The nation was in the midst of a serious measles outbreak and communities across the U.S. were seeing decreasing immunization rates among children.
NIIW provided an opportunity to draw attention to these issues and to focus on solutions. During the last week in April, hundreds of communities across the United States join those in countries around the world to celebrate the critical role vaccination plays in protecting the health of our children, families, and communities.
