The aim of the study was to assess barriers to Vaccines for Children (VFC) provider practices participating in the COVID-19 Vaccination Program and intentions to offer COVID-19 vaccination to children aged <5 years. We invited a random sample of 15 000 VFC provider practices in the United States to complete an online survey during February 28 to March 11, 2022. Of 2809 practices that completed the survey, 2246 (80.0%) were enrolled in the COVID-19 Vaccination Program. Concerns around staff resources, vaccine and supply storage space, and vaccine wastage from multidose vials were the most frequently reported program-enrollment barriers. Among enrolled practices that have decided whether to offer COVID-19 vaccination to the children aged <5 years, 1641 (88.8% of 1848) reported likely offering it to current patients, and 1165 reported likely offering it to children who are not current patients. Addressing participation barriers and encouraging active promotion may increase COVID-19 vaccination coverage of children.
