Your provider cannot give you a dose of vaccine that does not follow its specific vaccine product guidelines and requirements. All COVID-19 vaccine providers in the United States must be enrolled in the CDC COVID-19 Vaccination Program. To participate in this program, vaccine providers sign an agreement that states they will only administer COVID-19 vaccines in accordance with program requirements and recommendations including those of CDC, the Advisory Committee on Immunization Practices (ACIP), and the U.S. Food and Drug Administration (FDA). Your provider can refer to the CDC Interim Clinical Considerations for Use of COVID-19 Vaccines in the United States for specific information on administration of COVID-19 vaccines. These guidelines are based on safety and efficacy data and are updated as new information becomes available.
