Oxford-AstraZeneca Vaccine Effective Against Severe Covid-19, New Trial in US Confirms

News 18  

A large trial in the US and two South American countries of the Oxford-AstraZeneca vaccine has shown 79 per cent efficacy rate at preventing symptomatic COVID-19 and 100 per cent effectiveness in stopping severe disease and hospitalisation, the biotech firm said on Monday. The vaccine’s efficacy was consistent across ethnicity and age, and in participants aged 65 years and over, its effectiveness was 80 per cent. In the trial, which recruited over 32,000 volunteers across all age groups, the participants received either two standard doses of the Oxford-AstraZeneca vaccine or a placebo vaccine, at a four-week interval. In many different countries and across age groups, the vaccine is providing a high level of protection against COVID-19 and we hope this will lead to even more widespread use of the vaccine in the global attempts to bring the pandemic to an end, said Sarah Gilbert, Professor of Vaccinology, and co-designer of the ChAdOx1 nCov-19 coronavirus vaccine named AZD1222 by AstraZeneca.
