Moderna's current vaccine shot is a 100-microgram dose, compared with Pfizer's 30-microgram dose. Cutting the Moderna doses in half could help reduce the risks of side effects from the booster. It would provide more doses of the COVID-19 vaccine to help more people get the booster when it's their turn.

Also, Moderna has been shown to be more effective than Pfizer at preventing hospitalizations, so the FDA believes a half dose could be effective in keeping protection intact, according to reports.
