Delta variant will lead to increase in breakthrough Covid infections among vaccinated, Moderna says
The highly contagious delta variant will lead to an increase in breakthrough infections among the fully vaccinated as people begin moving indoors after the summer, Moderna said Thursday.
While Moderna’s two-dose vaccine remains “durable” six months after the second shot, immunity against the coronavirus will continue to wane and eventually diminish vaccine efficacy, the company said in slides that accompanied its second-quarter earnings report.
The company said its vaccine is 93% effective six months after the second dose. By comparison, Pfizer and BioNTech said their vaccine efficacy declined to around 84% after six months.
“Given this intersection, we believe dose 3 booster will likely be necessary prior to the winter season,” Moderna wrote.
