Covid

The Prime Minister’s roadmap rules would logically dictate not moving to stage four of lockdown easing on 21 June, but delaying by two or four weeks – because the increase in the R transmission rate to more than one is driven in part by the stage two and stage three easings and not just by the greater transmissibility of the Delta variant. As Nadhim Zahawi said on the Peston show last Wednesday, the more significant characteristic of the Delta variant is that one vaccine dose is not terribly effective against it, though two doses provides decent protection. And that good protection kicks in two or three weeks after the second dose.

Should the NHS be mixing vaccines for better effect, or at least offering people who have had one dose of the AstraZeneca vaccine the choice of having the Pfizer vaccine for their second shot?  The question arises because that is exactly the regime which has been followed in Germany since the risk of clotting from the AstraZeneca vaccine became evident. When the German authorities made the decision to administer the Pfizer vaccine in place of a second shot of AstraZeneca there was not much evidence as to whether this would be an effective strategy.  But a study from a group of hospitals in Berlin suggests that a shot of AstraZeneca followed by Pfizer is at least as good as two shots of Pfizer and may even be slightly better at producing immunity.

In recent days, it has been striking how many people in Westminster and Whitehall now think the lab leak theory is the most plausible explanation of Covid’s origins. China’s apparent success last year at stamping out the virus at home — with technological competence and sheer brutality — while cases spiked in the West, created a fear that the future belonged to Beijing.  But, as I say in the magazine this week, the growing plausibility that the virus leaked from a lab highlights the Achilles’ heel of the Chinese system: its lack of a mechanism for error correction. It is not that a lab leak couldn’t have happened in the democratic world, but it is far harder to imagine it being covered up here.

Amidst the drama of Dominic Cummings's appearance in front of MPs last week, perhaps the most important thing the PM's former adviser said was almost entirely ignored. As well as slating his former boss, Cummings criticised the UK’s disaster planning. The pandemic has shifted attention to how Britain would deal in the future with another respiratory virus, but arguably a bigger threat to this country – and, indeed, the world – has been forgotten. When it comes to dealing with solar flares, Cummings's said, ‘the current Government plan is completely hopeless. If that happens then we’re all going to be in a worse situation than Covid’.

Did Matt Hancock’s negligence lead to Covid seeding into care homes because patients were not tested before being discharged? This was one of Dominic Cummings’s more potent charges  and it brings back memories for me because I spent a chunk of last summer looking into this. In my line of work, the success rate for stories is quite low: investigate five avenues and you’re likely to find four dead ends. So you end up with a lot of data and research that’s never used, because the original premise doesn’t hold up. I was (and remain) critical of much of government policy on Covid response: it seemed horribly plausible to me that panicked NHS discharges were behind the staggering care home death count.

It is hard to remember a time when the daily drip of Covid statistics was not part of our lives. Since March 2020, we have been greeted every afternoon with a stream of government released data filling us in on the number of infections, hospitalisations and deaths. But how necessary is it today? With a current seven-day average of only seven Covid deaths a day, the lowest level since 15 March 2020, what do we stand to gain by continuing with this current approach? It is becoming increasingly apparent that the Indian variant is not going to swamp hospitals – and that concerns about fully unlocking on 21 June are over-egged. Even if this particular variant does prove to be more transmissible, the effectiveness of the vaccines prevents it from being of much concern.
