COVID fatigue is the biggest challenge, according to health experts and frontline healthcare workers. Expect to hear more calls to MaskUp! in the days ahead, and please set good examples for others around you by covering your face, giving others space, and cleaning hands frequently.
Pfizer released final data early Wednesday from its COVID-19 vaccine trial, and the results are beyond anyone’s expectations. There were 170 confirmed cases of COVID-19 in the 8,000 person data set that was evaluated. Of those, 162 infections were in the placebo group and 8 who received the active vaccine - meaning 95% efficacy, the company said.
Only one of the eight cases among the vaccine group was serious, which suggests that the vaccine may reduce severity even if it does not thwart infection.
Moderna’s final results should follow soon.
Pfizer says it will request FDA clearance for its vaccine “within days.”
