The Health Secretary claims that vaccines have prevented more infections than there have ever been in the pandemic
Health Secretary Sajid Javid recently made the claim that 24 million infections, 82,000 hospitalisations and 95,000 deaths had been prevented by the vaccination programme. The press picked up on the first figure with front page headlines claiming 100,000 lives had been saved. Let’s leave aside the question of how there could be more deaths saved than reduced hospitalisations of the at risk age group, and focus on the 24 million figure.
These are English figures and there are only 56 million people in England. By May 2020 it was estimated that 7%, or 4 million had been infected. Based on ONS data, and assuming positivity lasts on average two weeks, a total of at least 11 million people in England have been infected since and have protection from natural immunity. NHS England states that as of 26 August, 500k under 18 year olds had been vaccinated. A further 11 million under 18s are therefore unvaccinated. Therefore there are 26 million people in England who could not have benefitted from vaccination.
|56 million||Whole population of England|
|4 million||Number infected by May 2020|
|11 million||Number infected since|
|11 million||Number of unvaccinated under 18 year olds|
|26 million||Number who could not have been protected by vaccination|
That leaves 30 million. Of these there will be some who are unvaccinated but there is no data on the proportion of the unvaccinated who have had a previous infection so the following assumptions are based on the full figure of 30 million — assuming they have all been vaccinated.
Sajid Javid suggests that 80% of this population would have been infected if it were not for vaccinations. A claim of this magnitude shows quite some Chutzpah, especially as data from Israel seems to be indicating that the current crop of vaccines don’t seem to be particularly good at preventing infection.
Let’s add some context. According to the ONS, in the first year from March 2020 until the end of February 2021, 12 million people in England had been infected. For his conclusion to be true, there would have to have been more than twice as many infections in the last 6 months as we had in the first whole year of the pandemic. There would have had to be more infections every day than any day thus far, in fact an average of 150,000 infections a day, every day, for the whole 6 months. Add in the fact that the last 6 months were outside of the normal respiratory virus seasons and the claim is even more preposterous.
The original trials showed that between 78 and 119 people needed to be vaccinated to prevent a single case. The best vaccine, by this measure, required 78 people to be vaccinated. The follow up for the 78 estimate lasted 3 months. Assuming that the effectiveness can be extrapolated, then every 3 months one case would be prevented for every 78 people vaccinated. Therefore over a 6 month period the number needed to vaccinate to prevent a single case would be 39. To prevent 24 million infections over a 6 month period would therefore require nearly 1 billion people to be vaccinated. It is arguable that the number needed to treat to prevent a case will be lower during high prevalence periods when more people are at risk, than low prevalence ones. The prevalence during the Astrazeneca trial was high at 1.9%, so the 78 figure should apply during high prevalence periods. Sajid Javid’s claim is that over 6 months the number needed to vaccinate to prevent one case was nowhere near 39 and closer to only 1.
If he really believed this is true, then he must also conclude what follows: there are only 6 million adults still susceptible to infection because the rest are protected by vaccine or previous infection. Even chicken pox, which is much more infectious than SARS-CoV-2, cannot spread once 90% of the population have immunity. If he was right then the pandemic is behind us, as Neil Ferguson recently claimed.
Back in the real world, there will be deaths this winter from respiratory viruses and it is highly likely that the predominant respiratory virus this winter will continue to be SARS-CoV-2. HM Government knows this. That is why they are seeding thoughts of another lockdown when deaths reach 1,000 per week. Apart from there (still) being no scientific or moral justification for locking down, this is a disastrous measure to use: the ONS reports that winter deaths ‘from respiratory disease’ (i.e. due to the respiratory virus which happens to predominate that winter) usually peak at between 2,500 and 3,500 per week.
Unless stopped by democratic means, then, HART fears that HM Government will likely continue with its “discuss, deny, deploy” modus operandi, implementing lockdown suddenly before people get a chance to protest. Never has it been more important to lobby your MP and to encourage your friends and family to do the same.
