National Infant Immunization Week (NIIW)

National Infant Immunization Week

National Infant Immunization Week (NIIW) is a yearly observance highlighting the importance of protecting children two years and younger from vaccine-preventable diseases (VPDs). This year, in particular, it’s critical to ensure that families stay on track for children’s routine checkups and recommended vaccinations following disruptions from COVID-19.

CDC report released in May 2020 found a troubling drop in routine childhood vaccination as a result of families staying at home. CDC and the American Academy of Pediatrics (AAP) recommend that children stay on track with their well-child appointments and routine vaccinations. On-time vaccination is critical to provide protection against potentially life-threatening diseases.

NIIW 2022 is April 24 – 30, 2022.
