But the risk of dying from Covid-19 is extraordinarily dependent on age: it halves for each six to seven year age gap. This means that someone aged 80 who is fully vaccinated essentially takes on the risk of an unvaccinated person of around 50 – much lower, but still not nothing, and so we can expect some deaths. The PHE report also reveals that nearly a third of deaths from the Delta variant are of unvaccinated people over 50, which may be surprising given high vaccine coverage; for example, OpenSAFELY estimates more than 93% among the 65-69s. But there are lower rates in deprived areas and for some ethnicities and communities with limited coverage will continue to experience more than their fair share of loss.
