People who have been vaccinated against coronavirus, if they do become infected, have milder Covid-19 illness than unvaccinated people, a new US Centers for Disease Control and Prevention study shows.
A BBC report states the study, which looked at more than 3,900 essential workers, shows fully vaccinated people are more than 90% protected against infection. Even partially vaccinated people are 81% less likely to become infected than people who haven’t had been inoculated, according to the ongoing study.
“This adds to the growing body of real-world evidence of their effectiveness,” the CDC said Monday in a statement.
The study of health care staff, first responders and other frontline essential workers who have been tested weekly since December showed that so far 5% have tested positive for coronavirus. Only 16 of the 204 people who became infected had been vaccinated.
