NIIW (National Infant Immunization Week)

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 — even during 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 even during the pandemic.  As in-person learning and play become more common, on-time vaccination is even more urgent to help provide immunity against 14 serious diseases.

NIIW 2021 is April 24 – May 1, 2021.
