Public Health England estimates around 84,600 deaths and 23 million infections have been prevented as a result of the COVID-19 vaccination programme in England so far.
Professor Tim Spector, lead investigator on the Zoe Covid Study app behind he research, said: “Waning protection is to be expected and is not a reason to not get vaccinated.
“Vaccines still provide high levels of protection for the majority of the population, especially against the Delta variant, so we still need as many people as possible to get fully vaccinated.”
He also estimates protection against infection could drop to 50 percent by winter and that booster shots will be needed.
