Devastating New Data From PHE Shows Vaccine Effectiveness Down to 17% and No Reduction in Infectiousness – But Mortality Cut by 77%

PHE's latest technical briefing on the variants of concern has some key data on the performance of the vaccines.

6 min read

Public Health England yesterday released their latest technical briefing on the variants of concern, number 20, and it has some illuminating data.

It provides us with the infection, hospitalisation and death rates for the Delta variant, broken down by vaccination status and age. This allows us to do a calculation of the real-world vaccine effectiveness in the over-50s during the Delta surge, albeit a rough one without any adjustments.

The latest report has data up to August 2nd. If we substract from these values the data in Briefing 17 (up to June 21st) then we get the data covering the period June 22nd to August 2nd, which broadly corresponds to the bulk of the Delta surge in the U.K. The vaccine rollout to the over-50s was basically complete by this point, having stabilised according to PHE at around 88% double vaccinated and 10% unvaccinated (the other two per cent remaining single vaccinated, perhaps due to a bad reaction to the first dose).

In this period the PHE data tells us there were 2,464 Delta cases in the unvaccinated over-50s and 17,926 in the fully vaccinated over-50s. From this we can estimate the vaccine effectiveness against infection in the over-50s during the Delta surge as 17% (1-[(17,926/88%)/(2,464/10%)]). This confirms using additional data the estimate I made last week.

We can make a similarly rough calculation of the vaccine effectiveness against death. Between June 22nd and August 2nd, PHE reports that among the over-50s there were 339 deaths with the Delta variant in the double vaccinated and 167 in the unvaccinated. Using the same proportions vaccinated and unvaccinated as above, this gives a vaccine effectiveness against death in the over-50s during the Delta surge of 77% (1-[(339/88%)/(167/10%)]). Interestingly, this is very similar to the latest estimate of vaccine effectiveness against serious disease from Israel, which is around 80%. This is a decent level of protection and helps explain why the Delta surge had proportionally fewer hospitalisations and deaths, but it is well below the levels suggested by earlier studies and quoted by PHE, which are north of 95%.

Another noteworthy point from the briefing is that the secondary attack rate (SAR, the proportion of contacts that an infected person infects) of the Delta variant has continued to decline as the surge exhausts itself. The household SAR is now at 10.8%, down from a high of 13.5% on May 4th. This means nearly 90% of the people who live with someone infected with the ‘highly transmissible’ Delta variant do not contract the virus, an indication of widespread (and growing) immunity to the variant. Note that this is well below the 15.5% ‘direct contact’ SAR of the Alpha variant in the middle of December, giving the lie to the oft-repeated claim that Delta is intrinsically more infectious than Alpha.

Notes: 1. Study period start date is January 5th except for values between April 28th and June 1st when it was March 29th (this is why the Alpha line deviates from trend for this period). 2. Up to January 10th the value shown is the SAR of ‘direct contacts’. Between March 7th and May 5th it is the overall SAR (a lower quantity than the direct SAR). From May 19th it is the SAR of ‘household contacts’ (a higher quantity than the overall SAR and similar to the direct SAR). These parameters have been chosen from the data provided as a best fit to allow comparison given data for which the parameters presented vary from report to report.

A final point is that the briefing includes for the first time important analysis showing the vaccines are unlikely to do much in the way of reducing how infectious a person is. The researchers found that samples from vaccinated and unvaccinated infected people had similar average cycle threshold (Ct) values, meaning they had similar viral loads, suggesting a comparable level of infectiousness. The authors write:

In the NHS Test and Trace (NHSTT) case data, the mean and median lowest Ct values for all cases with Delta, where Ct data are available, since the 14 June 2021 are similar, with a median of 17.8 for unvaccinated and 18.0 for those with 2 vaccine doses. This means that whilst vaccination may reduce an individual’s overall risk of becoming infected, once they are infected there is limited difference in viral load (and Ct values) between those who are vaccinated and unvaccinated. Given they have similar Ct values, this suggests limited difference in infectiousness. To note, this analysis is undertaken on case data and are not age-stratified. Findings can be influenced by test-seeking behaviour, as well as true changes in the data, for example the age distribution of cases, which can also influence Ct values.

Average daily lowest Ct values for vaccinated vs. unvaccinated cases, by variant from NHSTT data from 1 September 2020 until 25 July 2021. Notes: This Figure shows the Ct values (higher count for lower viral loads) in people who catch the Alpha variant (referred to as SGTF, shown in red, yellow and brown), or Delta variant (Delta compatible referred to as All3P or S+, shown in green, blue and purple). For each variant, a comparison is shown between Ct values of unvaccinated cases, cases with 1 vaccination dose more than 21 days ago, and cases with 2 vaccination doses more than 21 days ago. Since May 2021 the average Ct values for Delta cases overall in the NHSTT case data (using the S gene as a proxy), have decreased (meaning average viral loads have become higher), which is a known pattern in an increasing epidemic (and was previously seen when the original ‘wild type’ virus was no longer prevalent).

This new data from PHE is in line with the latest findings from Israel, where the SAR was no lower among the vaccinated, and from the U.S. CDC, which found no difference in average Ct values between vaccinated and unvaccinated people.

Many news outlets have picked up this story, but few have drawn the obvious conclusion: that this further undermines the case for vaccine passports as it suggests vaccinated people are no less likely to pass on the virus than unvaccinated people. When added to the very low vaccine effectiveness against infection it’s hard to see how there is any case for vaccine passports left at all, even on their own terms, quite apart from any considerations of freedom and non-discrimination.

This latest data reinforces the picture that had been emerging in recent months of vaccines which do little to prevent infection or transmission (and thus to prevent or stop outbreaks) but which do reduce severe disease and death in the vaccinated, albeit not by as much as was originally claimed. This confirms that vaccination may be a good way of a person at high risk from the disease reducing their personal risk, but it has almost no value as a way of protecting others, so there is no benefit in vaccinating children, introducing vaccine passports domestically or internationally, or coercing young people to get a vaccine which to them is almost all risk and no benefit.

If you are comparing deaths in a group of under-50s and over-50s, then there are going to be more deaths in the over-50s simply due to age.

How do you correct for this in the stats?

If the vaccinated are 17% less likely to get infected, they are also 17% less likely to pass on the infection. So there is your demanded “reduction in infectiousness”. 17% is greater than zero for sure. But of course, on this very “sceptical” site it apparently does not matter to lie right there through the headline.

Well, this data shows that vaccine passports may still be required to protect all those old idiots who did not vaccinate from themselves.

Actually, this was my assumed justification all along, and I found it very idiotic for media to spin it into direction of “unvaccinated being the danger”. The truth is, everyone is a danger, and the unvaccinated will be just sacrificed to reopen businesses (but it’s hard to sell to public that way).

Again, when I look at the figures for Report 20 and Report 17, what I see is that in the over 50s the vaccine seems more effective on the face of it. 1.89% of those over 50 who have received 2 doses and who caught Covid then went on to die. In the unvaccinated over 50s who caught Covid, 6.78% went on to die. That is obviously a major improvement, but its still somewhat concerning that 1.89% of double vaccinated people went on to die. It must also be balanced against the level of side effects.

When I look at the figures between report 20 and report 17, what I see is that 0.06% of double vaccinated people under 50 who got Covid went on to die. 0.04% of unvaccinated people under 50 who got Covid went on to die. On the face of it, given the uncertainties around how much the vaccine reduces transmission, and the unknown side effects, this does not seem a great advert for extending vaccination to the under 50s.

Someone I know was terribly ill yesterday for no reason at all – out of the blue she suddenly felt sick, threw up, fever, chills, aches and pains – had to leave work early – I said it was probably something she had eaten – food poisoning maybe? But she dismissed that. Shes better today though – so she could have caught a bug.

I didn’t mention the vaccine but she has had both jabs.

Quite a few people I know who have had the jabs are coming down with kinds of weird bugs, illnesses, infections – not mention headaches and bouts of migraine …. one person I know complains of a terrible pain behind one eye for about a week now which she is taking paracetomol for – all very odd symptoms going around.

Just a thought. The lockdowns prevent people going outdoors, pretty much. Thus people’s vitamin d levels drop and their ability to fight infection drops significantly. The government and their advisors know this. Yet still they have plans to do this again. When combined with a complete failure to encourage people to take vitamin d supplements it seems like a deliberate action on the government’s part.

As viruses mutate they become less deadly and less virulent. This is standard happening. The claim that the experimental jab has anything to do with this has no provable basis in fact.

Willie still playing with government toys regarding the same-iants, I see.

Assumptions about mortality being related to the vaccine are mickey-mouse in the extreme. The most probable explanation is the growing (and expected) lessening of virulence of the virus, and growing general immunity.

Viruses do mutate. Normally this isn’t an issue but the Covid ‘vaccines’ only focus on a very narrow target. Mutations which alter the S1 sub-unit of the spike protein could result in immune escape – or worse – ADE.

I suspect we just have a situation in which vaccine immunity is waning. We could confirm this by comparing infection rate in those who were vaccinated early with those who have been vaccinated more recently.

Sorry Will, but this is all a nonsense. For some time now, we’ve known these are not ‘vaccines’ in any sense of the word, so their ‘effectiveness’ has always been moot. And as for mortality being ‘cut’, well, it’s summer.

Well, I think most people’s default understanding of vaccines is that once you’ve had one, you’re immune to the thing it is vaccinating you against. Meaning you won’t get it and you can’t spread it. That’s not the case with covid vaccines. I accept that’s not the case with flu vaccines either, but I think they are a category apart and most people’s assumption was that once they had been jabbed, that was it.

That is a very misleading analysis. All last year, Thailand had very few cases and very few deaths, making the government complacent about vaccines.

In April this year, Delta hit, the cases and deaths went up rapidly, and the government belatedly started a mass vaccination program in June which has still only reached a small fraction of the population, with civil servants and health officials getting priority.

It is quite incorrect to suggest that vaccination is the cause of the vastly higher death numbers, if that is what you were suggesting.

The mortality rate has indeed fallen over time, from 1.85% to 0.81%. But the massive increase in case numbers has caused a rise in deaths from a very low starting point.

I call bullshit. This news report from Israel states that it is the vaccinated who are filling up the hospitals.

“95% of the severe patients are vaccinated”.
“85-90% of the hospitalizations are in Fully vaccinated people.”
“We are opening more and more COVID wards.”
“The effectiveness of the vaccine is waning/fading out”

These figures just relate to a general hospital in Jerusalem not Israel as a whole.Last night in the the whole of Israel about 1/3 is unvaccinated in ICU and not only 5 % as in the Jerusalem hospital as reported in IsraelTV.The interesting thing though is that Jerusalem is the worst vaccinated part of Israel with only about 45% vaccination uptake but have this astonishing figure in the ICU as reported 95% vaccinated.

Covid Pass Exemption

It is not mandatory for an individual to wear a visual cue to outline they are exempt.

You should not ask these individuals to demonstrate their COVID-19 status through the NHS App.

So, if this was really about health and medicine, stop calling these drugs vaccines, stick to offering them to the vulnerable, but do so worldwide, and stop the coercion and discrimination campaign against the unvaxxed and the lies they are based upon, and abolish any vaxx passports, testing or qurantine requirements, especially and immediately those for the unvaxxed only, for good.
An apology would also be in order and appreciated. For a start.

Any “rational” argument for Vaccine Passports is now blown out of the water. The numbers in the last 4 briefings are consistent.

Given 95% of deaths are in people with 1 or more underlying health conditions I see no argument for vaccinating any other individuals.

The Cycle Threshold graphs were very interesting too. It’s the first time I’ve noticed such data.

All things being equal, is it not the case, if we go along with the new virus narrative, even though it’s provably bullshit, because we all have prior immunity, but are we not at the stage where “the virus” has run out of its core susceptible targets, so all that’s left is people with natural immunity? Until the ADE kicks in that is. As an aside, it would be great the see some DS coverage of ADE considering it’s the DS core readership ie unvaccinated people who could be in the firing line as an excuse for it and also considering that we might be about to witness something like 30% of our fellow countrymen die, backed up by hardcore science. It is time for the wider world to know about ADE, sooner rather than later, otherwise you are just making life easy for the lying deceiving pieces of human filth who are running this crap on us.

I hope you’re right about the reduction in deaths for the 50+, however I’m skeptical.
First Pfizer own study showed no statistical difference. Yes it was small but if the signal was as big as 77% it should be easily visible. Maybe age of the test participants can explain this, I don’t know.
Second, all cause excess deaths have been below baseline since march for UK. This suggests to me lot of 50+ “dry wood” was spent in the peak around January.
3rd, this is summer and excess deaths shows not much going on really. I think we have to wait until fall/winter when the level of susceptible are back up to normal levels and a proper “wave” before we see what actual protection these vaccines have.

Note: I’m also starting to wonder what these PCR tests actually test for. The virus mutates from a fall/spring loving variant, to a traditional winter variant to a summer variant?? And this story about the “virus haven’t been properly isolated” which I dismissed at first seem more and more real. Are there more than one virus we’re seeing? Is this another HIV/Aids PCR fiasco? (Or on purpose..)

There’s a very important caveat – deaths within 14 days of the first injection won’t count as vaxxed, yes? So if the vaxxing roll out during this period is increasing deaths, as we know they did in the elderly, they will be counted as deaths and proof of efficacy. Please point out if I am wrong.

If that’s true, it just does (partially) what it says on the tin. The fact that many politicians pretend that it does something brilliant, and are attempting to abuse the methodology in various ways is a different story. That said, I used the term ‘partially’, ‘cos I suspect it doesn’t express the whole truth on the ‘tin’ at all. Probably wouldn’t stand up in court, for that reason.

Would be interesting to see the age profile of the 339 / 167 vaxed/unvaxed deaths.

eg. if the unvaxed average age of death is significantly higher, then old-age will be a bigger factor rather than any alleged protective effect from the vaxes.

Also, I wonder how deaths due to the vax are classified? eg. if you fall ill and die within a few days of having the vax, how is this counted?

Another confounding factor is the PHE claim that 88% of over 50s are vaxed. We know that the actual UK population is 10-20% higher than official government figures which will further dilute the claimed vax effectiveness.

I still think there’s more conclusions that can be drawn from this graph… Take last month – why do all the alpha infections have a ct value of 18-20 – indicating that they are likely genuine infectious cases.
But the Delta infections have a ct value of 30-32 – past the point of clinical significance?
Am I missing something?

And if these ct values are available to PHE then why aren’t they reported to healthcare providers?

Eradication of Covid Is a Dangerous and Expensive Fantasy It seemed to work in New Zealand and Australia, but now ruinous, oppressive lockdowns are back.
Much of the pathology underlying Covid policy arises from the fantasy that it is possible to eradicate the virus. Capitalizing on pandemic panic, governments and compliant media have used the lure of zero-Covid to induce obedience to harsh and arbitrary lockdown policies and associated violations of civil liberties.
