Dr. Peter Marks, FDA about who should get updated COVID vaccine

- For unvaccinated individuals 6 months through 4 years of age, they're eligible to receive 3 doses of the updated authorized Pfizer-BioNTech COVID-19 vaccine or 2 doses of the updated authorized Moderna COVID-19 vaccine; individuals 6 months through 4 years of age who have previously been vaccinated against COVID-19 are eligible to receive one or 2 doses of the updated authorized Moderna or Pfizer-BioNTech COVID-19 vaccines. And the timing and number of doses to administer depends on the previous COVID-19 vaccine received.
- Individuals 5 years through 11 years of age regardless of previous vaccination status are eligible to receive a single dose of the updated authorized Moderna or Pfizer-BioNTech COVID-19 vaccines and if previously vaccinated, the doses administered at least 2 months after the last dose of any COVID-19 vaccine.
- Older children and adults, individuals 12 years of age and older are eligible to receive a single dose of the updated approved Comirnaty or the updated approved Spikevax vaccines and if previously vaccinated the doses administered again at least 2 months since the last dose of any COVID-19 vaccine-

Finally additional doses are authorized for certain immunocompromised individuals as described in the Moderna or Pfizer BioNTech vaccine fact sheets.
Based on the available evidence it's expected that the updated vaccines will provide good protection against COVID-19 from the currently circulating variants as we transition into fall and head into 2025.
