and there is a level of vaccine envy. it's kind of a race at this point between the vaccinations and the increase in cases at the moment. figures from the office for national statistics suggest that one in 540 people across the uk would test positive for covid. that is up — not hugely, about 10% on the week before. this vaccine push comes as public health england says 99% of the cases it's checking are now the delta variant. and since february, 806 people with it have needed hospital treatment, but only 84 of them were double vaccinated. and there's good news, too, about the impact of a single jab — if you've had two doses of either of these vaccines, you're more or less guaranteed not to end up in hospital. your chances of ending up in hospital are reduced by more than 20 times. and even one dose, once you've had a chance to make an immune response to it, will very substantially reduce the risk of ending up in hospital. just lift your sleeve for me, please. with just 31 days
