The Pfizer trial for the Omicron variant vaccine looks like it's not required for the unvaccinated. The trial is:
Once enrolled, they will receive either one dose of the omicron-focused vaccine, two doses four weeks apart from each other, or a third dose. Additionally, researchers will also recruit up to 600 people who received three doses of the current vaccine 3-6 months ago. These subjects will receive either one dose of the omicron jab, or a fourth dose of the current shot.
