The risk of suffering a breakthrough COVID-19 infection with the delta variant after being fully vaccinated with the Moderna vaccine may be much lower than the risk for those who received the Pfizer vaccine, according to a new Mayo Clinic study that is awaiting a full review.
The study found that in July in Florida, where COVID cases are at an all-time high and the delta variant is prevalent, the risk of a breakthrough case was 60% lower for Moderna recipients as compared to Pfizer recipients.
Similarly, in Minnesota last month, the authors found that the Moderna vaccine (also known as mRNA-1273) was 76% effective at preventing infection, but the Pfizer vaccine (known as BNT162b2) was 42% effective.
"Comparing rates of infection between matched individuals fully vaccinated with mRNA-1273 versus BNT162b2 across Mayo Clinic Health System sites in multiple states (Minnesota, Wisconsin, Arizona, Florida, and Iowa), mRNA-1273 conferred a two-fold risk reduction against breakthrough infection compared to BNT162b2," the authors wrote in their abstract.
