Refer to Table 34 for the age-appropriate primary series dosing.
Individuals 12 years of age and older who have partially completed the primary series should receive a single dose of the most current COMIRNATY presentation available.
Individuals who have previously completed a primary series with a COVID-19 vaccine: Individuals 6 months of age and older who have previously completed a primary series should receive a single dose with the most current COMIRNATY presentation at least 3 months after the previous dose.
Individuals may not be protected until 7 days after they have completed their dosing recommendations as noted in Table 34 (see Pharmacology: Pharmacodynamics under Actions).

Interchangeability with other COVID-19 vaccines: The interchangeability of COMIRNATY with other COVID-19 vaccines has not been established.
Paediatric population: The safety and efficacy of COMIRNATY in paediatric participants aged less than 6 months have not yet been established. Limited data are available.
Elderly population: No dosage adjustment is required in elderly individuals ≥65 years of age.

The effectiveness of a booster dose of COMIRNATY in individuals 65 years of age and older is based on effectiveness data in 306 booster dose recipients 18 through 55 years of age in Study 2, and an efficacy analysis from participants 16 years of age and older in 9,945 participants in Study 4.
