Interestingly, Moderna's booster dose is reduced to 25mcg per 0.5mL, but Pfizer is sticking with another 30mcg per 0.3mL shot.
I wonder if Moderna's will become the vaccine of choice given HC just authorized a two-month shelf life extension for it. |
minor correction
Moderna booster is 0.25 mL volume, 50ug RNA. Exactly half the normal Moderna dose
