The Pfizer-BioNTech and Moderna COVID-19 vaccines were found to be 94 percent effective in health care workers, according to the Centers for Disease Control and Prevention’s (CDC) ongoing largest effectiveness study.

The researchers estimated that those who were fully vaccinated were 94 percent less likely to develop symptomatic COVID-19, while people who were partially vaccinated were 82 percent less likely.

The CDC highlighted that the sample size reached a broader geographic area than the clinical trials, providing more evidence for the effectiveness. 

“This report provided the most compelling information to date that COVID-19 vaccines were performing as expected in the real world,” Director Rochelle Walensky 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 research involved 1,843 health care professionals between January and March of this year after most workers in the field were given priority to get the vaccine early in the country’s rollout. The data came from a network covering health care workers in 33 sites across 25 states.  ...
