AstraZeneca: Vaccine Provides ‘100% Efficacy’ Against Severe, Critical COVID-19 Disease

AstraZeneca said Monday that the results of its COVID-19 vaccine trials provide evidence that its shot provides “100% efficacy against severe or critical disease and hospitalization.”  AstraZeneca said in a statement that the safety and efficacy analysis was based on 32,449 participants in U.S. trials. “Vaccine efficacy was consistent across ethnicity and age. Notably, in participants aged 65 years and over, vaccine efficacy was 80%,” the statement said.  “The vaccine was well tolerated, and the independent data safety monitoring board (DSMB) identified no safety concerns related to the vaccine,” AstraZeneca said.  The U.S. trials also show the AstraZeneca COVID shot is safe and 79% effective against preventing symptomatic coronavirus, according to Britain’s University of Oxford, the developers of the pharmaceutical company’s vaccine.  Several European countries had recently stopped use of the AstraZeneca vaccine because of reports that it was associated with blood clots in recipients. The European Medicines Agency (EMA), however, said the vaccine is safe and does not raise the overall risk of blood clots.Last week, France, Germany and Italy resumed use of the vaccine.FILE – A member of the medical staff holds a vial of the AstraZeneca-Oxford COVID-19 vaccine at the South Ile-de-France Hospital Group in Melun, in the outskirts of Paris, Feb. 8, 2021.The World Health Organization (WHO) has subsequently recommended the use of the AstraZeneca vaccine against variants of the coronavirus.
