COVID-19 Vaccine Scheduling

Mercy’s Vaccine Clinic is providing:

• Pediatric Pfizer -BioNTech COVID-19 vaccine for children age 5-11 years
• Pfizer -BioNTech COVID-19 vaccine for individuals age 12+ years
• Janssen (Johnson & Johnson) and Moderna COVID-19 vaccine for individuals age 18+ years

The Pfizer vaccine series consists of two doses administered 21 days apart. The Moderna vaccine series is administered 28 days apart. While you should schedule your second dose to ensure the doses are administered as close to 21 days/28 days as possible, they do not need to be exact to the day. The Johnson & Johnson second dose can be administered no earlier than two months after the first dose.

Second doses administered within a grace period of ≤4 days from the recommended date for the second dose are considered valid; however, doses administered earlier do not need to be repeated. The second dose should be administered as close to the recommended interval as possible. There is no maximum interval between the first and second dose for either vaccine.

According to the CDC, high-risk individuals eligible for a third dose of Pfizer/BioNTech or Moderna are those who are 28 days past their second dose and have:

• Been receiving active cancer treatment for tumors or cancers of the blood
• Received an organ transplant and are taking medicine to suppress the immune system
• Received a stem cell transplant within the last two years or are taking medicine to suppress the immune system
• Moderate or severe primary immunodeficiency (such as DiGeorge syndrome or Wiskott-Aldrich syndrome)
• Advanced or untreated HIV infection
• Active treatment with high-dose corticosteroids or other drugs that may suppress your immune system

Per the CDC, patients will need to self-attest that they are severely to moderately immunocompromised, but proof of their condition is not required. Please bring your COVID-19 vaccination record card to your appointment; this shows when you received your COVID-19 vaccines and the type of vaccine that you received. Must be six months after the second dose of a series of two doses. For Johnson & Johnson one-dose series, you must be at least two months after the initial dose.
