Former Chief Science Officer Professor Sir Mark Walport has revealed that the number of people hospitalized with COVID is increasing, but not with the intensity of previous waves.
This is the key metric we’ve been waiting for – to see if the increase in cases, driven by the Delta variant, translates into more people falling seriously ill.
“Unfortunately, we are in the early stages of a third wave of the virus and it is this Delta variant, the so-called Indian variant, which has a very significant transmission advantage over the previous Alpha variant, the so- saying Kent variant – it’s about 60% more transmissible, ”Sir Mark told BBC Radio 4’s Today program.
“We currently have 7,000 cases on average per day and a doubling time which is about a week.
“Over 90% of new infections in the UK are of this variant, and it is increasing in most parts of the country, but not all.
“The good news is that we would be in real trouble without the huge success of the immunization program, so we have 75% of all adults who received the first dose and 50% who received a second dose. “
He added: “This variant shows some partial escape, especially from the first dose – so the first dose of vaccine is around 30% effective compared to 50% with the previous variant.
“We are starting to see the number of hospitals increase, but fortunately without anything comparable to the intensity that we have seen before. ”
