* For individuals younger than five years of age and individuals with moderately to severely immunocompromising conditions who have already received previous vaccine doses, recommendations on updated vaccine doses depend on the number of prior vaccines received. If they have received at least three mRNA vaccine doses, the updated vaccine should be given at least eight weeks after the most recent dose. Refer to other UpToDate content for details.
¶ Although the FDA authorized intervals for the second doses of the Moderna, Novavax, and Pfizer COVID-19 vaccines are four, three, and three weeks after the first dose, respectively, the CDC suggests an interval up to eight weeks. Extending the interval to eight weeks between vaccine doses may be preferable for those (especially males aged 12 to 39 years) who have no major comorbidities and do not need to maximize protection within a shorter period of time; longer intervals may be associated with a lower risk of myocarditis and slightly improved effectiveness.[5]
Δ If the patient was previously vaccinated with other formulations, give the first 2024-2025 Formula vaccine dose at least 8 weeks after the last vaccine.
◊ Children who turn five years of age during the series should receive all three doses with the formulation and dose recommended for children six months through four years.
§ If the only prior COVID-19 vaccine dose was a single Novavax COVID-19 vaccine, a 2024-2025 Formula vaccine dose can be given at least 3 to 8 weeks after that dose.
