Fully vaccinated workers were 94 percent less likely to develop symptomatic COVID-19 and people partially vaccinated were 82 percent less likely.
The study’s sample size covered a broader geographic area than the vaccines’ clinical trials, providing further evidence of their effectiveness, according to The Hill.
“This report provided the most compelling information to date that COVID-19 vaccines were performing as expected in the real world,” CDC director Rochelle Walensky, MD, said in a statement. “This study, added to the many studies that preceded it, was pivotal to CDC changing its recommendations for those who are fully vaccinated against COVID-19.”
The study included 1,843 healthcare workers and took place between January and March of this year at 33 sites across 25 states.
