Research from Israel lends support to UK’s decision to increase dosing gap to 12 weeks
A single dose of the Pfizer/BioNTech vaccine gives people 85% protection from Covid-19, according to a study from Israel.
Pfizer has consistently said that two doses of the vaccine are needed for high efficacy. In clinical trials, it reported efficacy of 52.4% after one dose, but 95% after two doses.
