A new study has found that people who received the Moderna COVID-19 mRNA vaccine are less likely to experience breakthrough infections compared to those who received the Pfizer-BioNTech mRNA shot.
The study, led by researchers out of Cleveland’s Case Western Reserve University, also found that people who received the Moderna jab were less likely to be hospitalized following a breakthrough infection than Pfizer vaccine recipients.
The findings were published Thursday, in the peer-reviewed Journal of the American Medical Association.
A breakthrough infection is when an individual tests positive for COVID-19 more than 14 days after completing the recommended series of a two-dose COVID-19 vaccine.
According to the study, researchers examined the electronic health records of more than 637,000 fully vaccinated patients from 63 healthcare organizations across the U.S., analyzing breakthrough COVID-19 infections, hospitalizations, and death rates between July and November 2021, when the Delta variant was the dominant virus strain circulating in communities.
