The Department of Public Health and Social Services (DPHSS) is notifying the public that the U.S. Centers for Disease Control and Prevention (CDC) will be conducting the 2024 National Immunization Survey (NIS) in Guam, starting in April 2024.

The survey is expected to be ongoing for several months or until the CDC collects their data.

CDC’s contractor, National Opinion Research Center (NORC) at the University of Chicago, will administer the Guam NIS. This survey is intended to help assess immunization coverage among children 19 to 35 months of age, and adolescents between the ages of 13 to 17 years old.

DPHSS Chief Medical Officer and Pediatrician Dr. Robert Leon Guerrero said, “We ask the public that if you are called to please cooperate, as the information collected is important.”

There are no-charge, off-island telephone numbers available and are as follows: 

  • (404) 809-2644
  • (404) 809-2195
  • (404) 806-4810
  • (404) 806-4811
  • (404) 806-4812

The National Immunization Survey is a random digital-dial telephone survey used to find households with children between the ages of 19 – 35 months or 13 – 17 years of age living in the home. Parents or guardians will be asked to provide information on the date and type of vaccinations given to their children. 

At the end of the interview, authorization to contact their child's vaccination provider will be requested from the parent or guardian.

All data collected will be sent to the CDC for analysis and then provided to the DPHSS Immunization Program to compare Guam’s vaccination rates with those of other states and territories.

If you have any questions concerning the NIS, please contact the DPHSS Immunization Program, at (671) 735-7143/148/160.
