Vaccines appear to cut Covid transmissions and infections by two-thirds according to the first “real world data” examining their impact, The Telegraph can disclose.
Key data being handed to Boris Johnson as he finalises a roadmap out of lockdown shows that just one dose of either the Oxford or Pfizer vaccines has such an effect on all age groups.
Mr Johnson and his scientific advisers are expected to examine key findings showing the impact of the jabs on transmission, infection, hospitalisations and deaths.
Whitehall sources said the studies would be a crucial part of deliberations over Britain’s route out of lockdown and that all the findings so far were “very encouraging”.
Separate data shows that Covid cases are falling most rapidly among the oldest, with care home outbreaks almost halving in a week.
The statistics appear to vindicate Britain’s strategy of vaccinating by age order, with cases among those over the age of 80 falling by 38 per cent in seven days.
