Moderna vaccinations are effective longer than both the Pfizer BioNTech and Johnson & Johnson COVID-19 vaccines, NPR reported Friday.
According to the outlet, the Johnson and Johnson vaccine, the only single-dose COVID-19 vaccine approved for use in the U.S., has the least effective protection over time. Researchers have stressed that all three vaccines can reliably prevent severe illness and hospitalizations.
More than 3,000 people hospitalized between March and August were part of the study. Moderna vaccinations, which are approved for emergency use by the U.S. Food and Drug Administration, have proved to be 93 percent effective at a steady rate. Over time the effectiveness of the Pfizer vaccine dropped from 91 percent to 77 percent and the Johnson & Johnson vaccine was 71 percent effective.
Moderna may have more long-lasting protection because it uses a string dose of mRNA vaccine spaced out over a longer period of time than the Pfizer vaccine.
Pfizer, developer of the only fully FDA-approved COVID-19 vaccine, has developed a third booster shot. However, the FDA Friday announced it would only recommend boosters for people aged 65 and older or those at high-risk for dangerous infection.
