Considerations for Minimum Intervals for COVID-19 Vaccine Doses

The minimum interval between the first and second doses continues to be recommended for:

• People who are moderately or severely immunocompromised
• People ages 65 years and older receiving Novavax vaccine
• Situations when the fullest possible protection needs to be achieved sooner (e.g., increased concern about an individual's higher risk for severe disease)
