There is a lot of nonsense about Zero Covid being an extreme position, only possible in repressive states (er..S Korea, Taiwan, Thailand, Norway, Finland, NZ??) and our UK strategy reflects a more sensible centrist view. So compare the UK with successful countries...(1)
In fact we had a clear statement for proper public health control of the epidemic from WHO on Jan 29 2020, and the China Report from WHO on Feb 24 2020. All measures were not controversial and not based on rocket science or modelling. (2)
A new paper from Anhui province (pop 64 million, almost same as UK) in China shows how control was achieved without any severe or prolonged lockdown. sciencedirect.com/science/articl… (3)
The devolved administration identified 991 cases in January and February last year. They also tracked down 29,399 contacts through local community based workers. Note the ratio: they detected 30 contacts for every case, far higher than in the UK. (4)
Now read the interventions they arranged within a week of identifying the first case. Then read it again and consider how many we did here in the first wave, and how many we are doing now a year later? Yes, its embarrassing.(5)
Now look at the outcomes in Anhui province, the same size as the UK. They achieved elimination of new cases in six weeks. (6)
The UK wasted £22 billion on a system not run by public health experts. We had to borrow £373 billion even before the second surge. The loss of GDP and future unemployment suggest the impact of the pandemic could cost us a sum of more than a trillion pounds. (7)
We could have done what they did in one province of China (which is much poorer than us) if we had invested in strong public health, included independent PH advisers on SAGE, and mobilised districts and communities. We still aren't doing it. (8)
We halved all public health funding between 2012 and 2020, to a paltry £3 billion per year, even though a pandemic has consistently been the biggest threat to the country, higher even than war. We spend 13 times more on defence than PH. And 400x more than on infection control (9)
And the decision of our PM not to attend the first five meetings of the main COBR committee to tackle a pandemic we knew about on January 30, a delay of five weeks, was an act of omission beyond comprehension. (10)
The reliance on vaccines alone as a strategy for control while transmission remains high, and isolation of cases and contacts is an expensive joke, is incredibly risky. The threat of vaccine resistance remains high. (11)
Journalists, MPs and the public should ask daily why the public measures implemented by countries and provinces (like Anhui) which eliminated Covid from their territories, are not being implemented in the UK (12).

Today we lost 1820 of our citizens. Many of these deaths could have been prevented. I plead with our Secretary of State @MattHancock and @CMO_England to make changes to our community protective shield as follows: (1)
Face the data with humility. Latest data show only 32% of in-person test results were received within 24 hours...Way too slow. For all routes combined, 18.3% of tests from all test sites were received within 24 hours of a test. (2)
Since Test and Trace launched, 97.8% of all contacts managed by local health protection teams have been successfully reached. Performance of call centres is much worse. The % reached within 24h of the case that reported them reaching the contact tracing system fell to 67.7%. (3)
SAGE Minutes Dec 22: "It is highly unlikely that measures with stringency + adherence in line with the measures in England in November (i.e. with schools open) wd be sufficient to maintain R below 1 in the presence of the new variant. R would be lower with schools closed"
SAGE Minutes Dec 22 "It is not known whether measures with similar stringency and adherence as Spring, with both primary and secondary schools closed, would be sufficient to bring R below 1 in the presence of the new variant." google.com/search?client=…
SAGE Minutes Dec 22 "ACTION: PHE to share information on new variant and South Africa variant with policymakers and ministers for consideration of action".
The PM says all frontline workers, people aged 70+ and people with serious underlying conditions will be vaccinated by mid-February. That’s 13 million, so 2 million per week. Potentially doable if GPs are supported with staff, volunteers funding and supplies. (1)
We must see a generous allowance funded by Treasury for isolation when infected or a contact. Without it, transmission will remain high increasing the risk of vaccine resistance. If not, could be the costliest mistake of the whole pandemic. (2)
Border screening must be made much tighter. Especially to identify new aggressive strains from other countries. (3)
Modellers believe that spreading out our limited supply of vaccine as single doses for 3 months will save up to 6000 lives. One concern though is whether single doses might lead to 'vaccine resistance' through virus mutation. (1)
If we assume that over the next 12 weeks 12-20 million people get one dose of a vaccine and are told or believe it gives 90% protection what % will actually go for a second jab? We might assume second dose coverage is at best 70%. (2)
That means between 4 and 6.7 million people might have fading protection. Will the risk of creating a vaccine resistant mutant in this group of people, which could spread rapidly to 7 billion people around the world, outweigh the benefits of 6000 deaths prevented. (3)
We need more information on the immunisation plan. In the two weeks from Dec 8-20 we immunised 616,000 people, say 52,000 per day. With the new Covid variant we might assume up to 70% coverage to achieve herd immunity (1).
70% of 68 million people = 48 million people who need 2 doses one month apart. That is 96 million doses.
If we just vaccinate the over 65s (12m), front line workers (2m) and people with underlying conditions (8m) we shall need 22 million x 2 = 44 million doses. (2)
At current rates it will take 846 days to fully vaccinate 22 million people + 1846 days to achieve herd immunity. WAY TOO LONG! So how many jabs per day to vaccinate high risk 22 million people in say 3 months (13 weeks)? Answer: 484,000 doses per day, working 7 days per week.(3)
Scientific models vary according to the assumptions made. Compare here the projections for Covid19 deaths under four different epidemiological models (Imperial, LSHTM, Warwick, and Public Health England/Cambridge) and the dynamic causal model of Professor Karl Friston. (1)
Here are the four epidemiology scenario models which all show much higher daily death rates than the 'first wave' (dotted line). These informed government policy. (2)
This slide shown to COBR shows the steady rise in death rates up to the first wave peak in about one month's time. (3)
