The goal of the Arizona Healthcare, Emergency Response, and Other Essential Workers Surveillance (AZ HEROES) Study is to enhance our knowledge of the epidemiologic and immunologic characteristics of novel COVID-19 infection and reinfection among high-exposure individuals who provide critical services to our communities.

We are now enrolling children ages 4 months – 17 years into the AZ HEROES Kids Study. This CDC-funded ancillary study will help researchers learn more about SARS-CoV-2 infection in children and teenagers and how well the COVID-19 vaccine protects from infection.
