US CDC certifies Pfizer, Moderna vaccines 94% effective

The US Center for Disease Control and Prevention (CDC) has said that the Pfizer-BioNTech and Moderna Covid-19 vaccines have been found to be 94% effective in health care workers.

The confirmation of the vaccines follows the conduct of studies with a larger sample size from across a wider geographical area than in the clinical trials.

This disclosure is contained in a statement issued by CDC on Friday, stating that mRNA vaccines (Pfizer-BioNTech and Moderna) were found to reduce the risk of getting sick with Covid-19 by 94% among Health Care Personnel (HCP) who were fully vaccinated.

The preliminary study results released on Friday further supported previous data on the effectiveness of the two vaccines, which use mRNA technology and have been widely administered in the U.S.

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