Coronavirus vaccines developed on an mRNA technology, like those from Pfizer and Moderna, are "highly effective," in tamping down infections, including asymptomatic cases, according to findings posted Monday by the Centers for Disease Control and Prevention.
The federal health agency examined results from a real-world vaccine rollout among nearly 4,000 at-risk essential workers, like health care staff and first responders, across six states from Dec. 14 to March 13, 2021.
Results indicated a 90% drop in infection risk after participants were fully vaccinated, or in other words, two weeks after they received second jabs developed by Pfizer or Moderna. The findings also underscored a high level of protection after just a single dose; participants’ risk of infection was cut by 80% two weeks after their initial vaccination.
