Researchers studied more than 3,000 people hospitalized between March and August. And found the Moderna vaccine was 93% effective at keeping people out the hospital and that protection appears to be holding steady.

The Pfizer vaccine’s protection fell from 91% effective to 77%. The Johnson and Johnson vaccine was 71% effective.

The researchers speculated the Moderna vaccine may be the best because it uses a strong dose and spaced out the two shots a week longer.

The FDA is weighing whether to approve a booster for the Pfizer vaccine.
