My patient takes high dose steroids and received a single dose of Janssen COVID-19 Vaccine (Johnson & Johnson) in 2021. He has had no doses since. He fits the definition for moderate or severe immunocompromise. What do I do now?

Primary vaccination with the Janssen COVID-19 Vaccine requires only a single dose. People who received the Janssen COVID-19 Vaccine primary dose require only one updated (2023–2024 Formula) dose by Moderna, Pfizer-BioNTech, or Novavax to be up to date. People who are moderately or severely immunocompromised have the option to receive 1 additional updated 2023–2024 Formula COVID-19 vaccine dose at least 2 months later. Further additional dose(s) may be administered, informed by the clinical judgment of a healthcare provider and personal preference and circumstances. Any further additional doses should be administered at least 2 months after the last 2023–2024 Formula COVID-19 vaccine dose.

For all vaccination schedule options, refer to the printable interim COVID-19 vaccination schedules document from CDC: www.cdc.gov/vaccines/covid-19/downloads/COVID-19-immunization-schedule-ages-6months-older.pdf.
