AstraZeneca Coronavirus Trial Promises 'Highly Effective' New Vaccine-NPR

U.K.-based pharmaceutical company AstraZeneca has developed a vaccine that initial results show to be "highly effective in preventing" COVID-19, the company announced Monday. The vaccine, developed with the University of Oxford, showed an average efficacy of 70% in preventing the coronavirus, according to the company. However, that is an average of two dosing regimens — one involving two full doses at least a month apart that proved to be 62% effective. A second regimen, involving a half dose followed by a full dose at least one month later was 90% effective, the company said. NPR, 11/23/2020
