New analysis runs counter to earlier study which suggested one dose may not give adequate protection
One dose of the Pfizer/BioNTech vaccine gives people about 90% protection from Covid by 21 days, according to an analysis of Israel’s mass vaccination programme.
The data analysis, carried out by researchers from the University of East Anglia with UK government funding, runs counter to an earlier study from Israel which suggested that one dose may not give adequate protection.
