The vaccines produced by Pfizer Inc. and AstraZeneca have proven to be highly effective at preventing the hospitalization of those infected with the new delta variant. This underscores the urgency of getting people fully protected, according to health authorities in England.
The Pfizer and BioNTech SE shot has an efficacy rate of 96% against hospitalization after two doses. In comparison, the AstraZeneca and University of Oxford Covid inoculation have an efficacy rate of 92%, according to an analysis announced on June 14th by Public Health England. These results are comparable with the protection offered against the alpha variant, which first emerged in Britain, the data revealed.
“The vaccines are the most important tool we have against COVID-19,” Mary Ramsay, Public Health England’s Head of Immunization, said in a statement. “It is absolutely vital to get both doses as soon as they are offered to you, to gain maximum protection against all existing and emerging variants.”
