The recommended schedules for COVID-19 vaccines, beginning at age 6 months, vary by brand, age group, and by the presence of moderate or severe immunocompromise. Please refer to CDC’s Interim COVID-19 Immunization Schedule for Persons 6 Months of Age and Older www.cdc.gov/vaccines/covid-19/downloads/COVID-19-immunization-schedule-ages-6months-older.pdf.
There is a delay between the public announcement of a change in recommendations and the release of updated CDC guidance documents. Information is generally updated first on the CDC web page: Use of COVID-19 Vaccines in the United States (www.cdc.gov/vaccines/covid-19/clinical-considerations/covid-19-vaccines-us.html). Check the date of the schedule you are using to see if it predates a change in recommendation. Periodically verify whether you are using the most current available documents by checking Immunize.org’s regularly updated Checklist of Current Versions of U.S. COVID-19 Vaccination Guidance and Clinic Support Tools: www.immunize.org/catg.d/p3130.pdf.
