National Infant Immunization Week (NIIW) is an annual observance to highlight the importance of protecting infants from vaccine-preventable diseases and to celebrate the achievements of immunization programs in promoting healthy communities throughout the United States. This year, NIIW will be April 27-May 4, 2019.

  • In 2019, we are celebrating the 25th anniversary of NIIW. When the NIIW observance was established 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.

Vaccines are among the most successful and cost-effective public health tools available for preventing disease and death. They not only help protect vaccinated individuals, but also help protect entire communities by preventing and reducing the spread of infectious diseases. Among children born during 1994-2018, vaccination will prevent an estimated 419 million illnesses, 26.8 million hospitalizations, and 936,000 deaths over the course of their lifetimes.

NIIW provided an opportunity to draw attention to these issues and to focus on solutions. Communities have continued to use the week each year to raise awareness about the importance of ensuring all children are fully protected from vaccine preventable diseases through vaccination. Today, many immunization programs, partners and communities can celebrate high infant vaccination rates.
