Moderna’s COVID-19 vaccine is slightly more effective than Pfizer or Johnson & Johnson’s at preventing hospital stays, although the gap widens significantly four months after vaccination, the CDC said on Friday.
The report comes just as the FDA is debating whether to endorse a controversial plan to introduce booster vaccinations for fully vaccinated people.
The data, collected over a five-month period from nearly 3,700 people in 21 hospitals in 18 states (including Montefiore in the Bronx), adds to growing evidence that all vaccines work well, but the Moderna shot works in the Remains most effective over time.

Overall, the study found, the Moderna vaccine was 93% effective in preventing hospitalization for COVID in American adults without compromised immune systems. During the same study period (March 11 to August 15), the Pfizer vaccine was 88% effective and the J&J vaccine was 71% effective.
But those were totals. The study also found efficacy, also known as VE, for the period of 14-120 days after vaccination and after the 120-day mark. There the numbers diverged even more clearly.
The Moderna vaccine remained 92% effective against hospital admissions after 120 days, while the Pfizer vaccine decreased to 77%. (There was no similar calculation for the J&J vaccine, although the CDC found that effectiveness decreased to 68% more than 28 days after vaccination.)
“Understanding the differences in VE across vaccine products can guide individual decisions and policy recommendations regarding vaccine boosters. All FDA cleared or cleared COVID-19 vaccines provide significant protection against COVID-19
Hospitalization, “write the study authors.
