The Moderna Booster has been recommended, this is NOT the same as approved. The recommendation by the FDA panel is just the first step in the approval process.
As soon as it is fully approved, we will let people know how and when they can book appointments.
A Booster Dose is different from a Third Dose. It is likely that if/when approved the Moderna Booster will be half the dosage of the first two shots, while the third dose which is only for the immunocompromised, is the full dosage, the same as the first two shots.
