Covid-19: Infections fell by 65% after first dose of AstraZeneca or Pfizer vaccine, data show
Infections of SARS-CoV-2 fell by 65% after a first dose of the Oxford-AstraZeneca or Pfizer-BioNTech vaccines, preliminary results from a large UK surveillance study indicate.
Reductions increased to 70% after a second dose of the Pfizer vaccine, data from the UK Covid-19 Infection Survey show. Not enough people had yet received two doses of the AstraZeneca vaccine to assess this.
