New research released by the Centers for Disease Control and Prevention on Friday shows that effectiveness of the Moderna vaccine is staying particularly strong.
Over the course of five months of research, from March to August, the effectiveness of all the vaccines at keeping people out of the hospital due to COVID among people without compromising conditions was highest for Moderna recipients, at 93%. Pfizer’s effectiveness was overall 88% and Johnson & Johnson’s was 71%.
Pfizer’s effectiveness decreased after 120 days of the study period, from 91% to 77%, while Moderna’s effectiveness did not see a similar decline. Initial effectiveness of 93% only declined to 92% with Moderna.
“Although these real-world data suggest some variation in levels of protection by vaccine, all FDA-approved or authorized COVID-19 vaccines provide substantial protection against COVID-19 hospitalization,” researchers concluded.
