Researchers from the Universities of Edinburgh and Strathclyde, in addition to Public Well being Scotland, discovered that the Pfizer vaccine supplied 92% safety in opposition to the alpha variant and 79% in opposition to the delta one 14 days after the second dose. That in contrast with 73% and 60% safety for the Astra vaccine. The authors warned that the vaccine comparability must be interpreted with warning as a result of observational nature of the information.
The research lined a demographic distribution of circumstances in Scotland from April 1 to June 6. Researchers stated a extra full evaluation from these outcomes can be made as soon as it was mixed with related research from the U.Ok. and elsewhere.
