Single AstraZeneca Vaccine Dose Highly Effective Against Delta Variant, Study Says
Canadian researchers found that one dose of the AstraZeneca’s COVID-19 vaccine, Vaxzevria, was highly effective at preventing hospitalization or death caused by the Delta variant.
A single dose was found to be 87 percent effective against the Delta variant, 90 percent effective against the Alpha variant and 82 percent effective against the Gamma/Beta variant, said researchers from the Canadian Immunization Research Network.
The analysis comprised nearly 70,000 individuals who contracted the SARS-CoV-2 virus from December 2020 to May 2021 in the province of Ontario. The non-peer-reviewed results were posted online on medRxiv.
