Researchers from the Universities of Edinburgh and Strathclyde, as nicely as Public Health Scotland, identified that the Pfizer vaccine provided 92% protection against the alpha variant and 79% against the delta one 14 days soon after the second dose. That compared with 73% and 60% protection for the Astra vaccine. The authors warned that the vaccine comparison should really be interpreted with caution due to the observational nature of the information.
The study covered a demographic distribution of instances in Scotland from April 1 to June 6. Researchers mentioned a more full evaluation from these outcomes would be made as soon as it was combined with comparable research from the U.K. and elsewhere.
