More on vaccine efficacy

In a Swedish study, the results of which are about to be published in the Lancet, vaccine effectiveness against COVID infection has been found to wane over 6 months. It is not obvious that there is any effect against infection beyond 6 months from date of full vaccination. Meanwhile, effectiveness against severe outcomes was found to wane over 9 months for men, older people and those with co-morbidities. The report is available here.

The search for the case for mandatory vaccination

Extraordinary claims require extraordinary evidence. Employment termination for not being vaccinated is surely sufficiently extraordinary to warrant demonstrable justification. If there is a case to justify firing an employee, then the data would support it. Right?

I can’t find any Australian data to support the mandate. Instead, I can see case numbers, deaths and vaccination rates. Take the following graphic from The Australian as typical. The curious reader might want to know if the increase in average daily new cases is different between the vaccinated and the unvaccinated, particularly among the ages of the workforce. I can’t find that breakdown in official data, although of course it will exist.

If the case numbers were much higher among the unvaccinated compared to the vaccinated, that would be helpful data to convince the public of the need for vaccination. If any readers know of the split, I’d appreciate a pointer to the data in the comments. Why the Australian state governments do not publish this is a mystery to me. Unless Occam’s Razor strikes again.

However, the UK health authority does publish its data.


This monthly snapshot shows infection rates split by age band and by vaccination status. Look at the last two columns. This is unlikely to convince the remaining unvaccinated to get vaccinated. Maybe a breakdown of deaths by age band and vaccination status would help? Again, this data will exist in Australia but I can’t find it. Thanks again to UK Health, here it is for the same monthly snapshot:

UK Health, ibid

Is the Australian data similar to this? Someone clearly knows. The UK experience shows a couple of things:

  1. The vaccines do not prevent infection. The case rate among the vaccinated vs unvaccinated was around 50% in the above UK data. Removing the under 18s from the rate sees it change such that the unvaccinated represented 16% of the cases. (The under 18 data is highly skewed to the unvaccinated and is therefore less reliable in this analysis.)
  2. The mortality differences between the vaccinated and unvaccinated are negligible until after the age of 50. The survival rate for unvaccinated people in the 50-59 age band is 99.99%. This reduces to 99.94% for 70-79 year olds. Even above age 80, which includes those who have already lived beyond current life expectancy, the survival rate is 85% for the unvaccinated.
  3. The virus continues to be an old person’s disease. Youth and the workforce are largely unaffected by being infected.

There is no case for mandatory vaccination presented here. Any business that terminates an employee for not being vaccinated risks a serious legal backlash down the road. If that were not the case, then the data to support such actions would be in the public domain.

COVID vaccine efficacy

The public policy response to COVID19 in most countries includes these two axioms – 1) mass vaccination is essential to end the pandemic, and 2) the vaccines do not prevent the transmission of the virus but they do result in a substantially lower seriousness of the illness in those that catch it.

So it is useful to interrogate these axioms by checking the actual data.

Here is how a small sample of countries is doing with vaccinations.

Israel did remarkably well to get above 50% over 6 months ago. Canada lagged but its vaccine roll out was then rapid. The UK and US are broadly similar. From this chart, the narrative would have you believe that the number of new COVID cases this year should have been highest in Canada, lowest in Israel with the UK and US in between. (Ignore Australia – there is insufficient data yet and it being a closed island creates a mismatch in comparisons to other countries; but I’ll leave the data as a sidenote.)

Here is the chart of new cases:

This chart shows the actual result to be opposite to the expected. Israel is suffering the most new cases, Canada the least and the UK, US in between.

What about the reduction in seriousness of the illness? Here is the case fatality rate:

Israel’s case fatality rate (CFR) has been very stable, showing some reduction this month. There is no obvious associated reduction in CFR with rising vaccination penetration.

Canada’s CFR dropped rapidly during the first half of this year while the vaccine penetration was only around 5% of the population. As the vaccine penetration rapidly increased, the CFR remained stable, with some reduction emerging just recently.

The CFR in the US is similar in pattern to Israel. The UK has seen a reduction in CFR in the last three months which roughly coincides with its increase in case numbers. Overall, the proposition that illness severity is reduced is not compelling.

There is enough evidence to conclude that mass vaccination is not going to end the pandemic. What is missing in this analysis is the effect of naturally acquired immunity relative to vaccine induced immunity. Could it be that a rapid vaccine rollout put a ceiling on natural immunity arising from cases of acquired COVID? I think that would be plausible. If so, an explanation for the actual data is that naturally acquired immunity is more effective than vaccine induced immunity.

We’ve been here before, right?

In the 1930s, the authoritarian forces of Nazism, Fascism and Communism were in the ascendency in Europe. A doctrine that became common to all of the architects and proponents of these ideologies was that the state must not be bound by the law. The rule of law neccessarily meant that the state was unfree. Giacomo Perticone put it this way in 1931: “During the whole of the evolution of judicial thought, one was led to the conclusion that a regime of law was one in which the State was a prisoner of the law, and as a consequence incapable of action, of will, of power, a State indecisive, emasculated and all that which follows.” It followed that a State bound by the rule of law was unfree and to be free to act justly it must not be subject to the obligation to follow the law. In other words, the State should be able to treat citizens exactly as it pleased. [Ref FA Hayek, The Constitution of Liberty]

The proponents and leaders of these totalitarian forces thus justified their right to ignore the concept of the rule of law. At a basic level, the rule of law can be considered as a legal system in which everyone is treated equally before the law, whether it be statute or common. The totalitarians devised their own justification for doing exactly the opposite. Orwell’s oft-quoted sentence from Animal Farm reads: “All animals are equal, but some animals are more equal than others.” The sentence captured both the concept of differing treatment and the abuse of language to maintain a power hierarchy and authority to coerce others.

A better roadmap

The Prime Minister's roadmap out of COVID19 and back to normal has been framed within a pretense of knowledge: that governments know best. It clearly foresees the continued use of coercive powers over citizens. This will be counterproductive and extend Australia's misery.

If the World Health Organisation had not changed its definition of pandemic in 2009, COVID19 would no longer be classified as such. Hence, national emergency powers would have been rescinded. The change in definition allowed emergency powers to be maintained, not on the basis of what actually was happening with infections, illness and mortality but on the basis of what might happen. The end result is what we see in Australia right now - 15 million or more people in lockdown in the face of how many actual deaths this year? The answer is twenty one.
An effective roadmap back to normal would begin today with the declaration that the pandemic is over and responsibility for personal health is now handed back to individual people. There is ample knowledge and good sense in the community. People are smart enough to make their own risk-adjusted decisions and mitigations. The real roadmap starts with this acknowledgement. 

Vaccinations do not prevent virus transmission – according to the CDC

The director of the US Centre for Disease Control has confirmed on CNN that vaccines do not prevent the vaccinated from being infected and spreading COVID19.

See this short clip from the interview.

Which means that as a strategy to suppress or eliminate the virus, vaccinations don’t work. Further, vaccination passports and similar restrictions on the unvaccinated would be unnecessary and unjust discrimination.

Truman’s attitude has infected current political leaders to the point of madness

The buck stops here.

President Truman’s sign on his desk. He meant that he was responsible for the decisions and if things went wrong he couldn’t blame anyone else. (What a fantastic film emulsion. I wonder if that photo was shot on the famous Ferrania P30 film? The emulsion is back in production and I have some on order. ISO 80. Classic Italian film look. But, I digress…)

It’s a sentiment that is admirable in times of national emergency. But nearly two years down the track after COVID19 first emerged, there is no longer a national emergency. Or international emergency.

Responsibility for keeping the noses of the public clean should now be handed back to the individual owner of each nose. It is no longer a matter for any politician. Anywhere.

Targeted Risk Mitigation

I am unaware of any country other than Sweden that has taken a targeted risk mitigation strategy to deal with SARS-COV-2. It appears to me that the citizens of other countries have been treated as amorphous, to be pummelled towards the impossible goal of virus elimination. “We had to destroy the village in order to save it.” That cliched quotation, supposedly from a US army general in Vietnam, may be a myth, but it does describe the apparent attitude of most governments in response to COVID19.

Risk mitigation has costs. Therefore, mitigation techniques should be applied only where they are needed and only if they can be reasonably expected to work.

Using Europe as an example, here is the median age data by country:

Across the continent, the median age is less than 44. (It has created up to around 46 in some countries.) That means more than half the European population is aged less than 44.

With that in mind, consider the mortality experience of the last 5 years up to the end of 2020, plus year to date 2021. This comes from the European Mortality Monitoring study that collects data from 29 participating countries. The following chart shows excess deaths (ie different from normal, where normal is based on continuous mortality investigations) for ages up to 44. Each line represents a calendar year of data, split by weeks 1 to 52. I have deliberately withheld the legend so that the lines are not identifiable as any particular year. Your challenge is to guess which coloured lines represent 2020 and 2021.

This analysis ought to inform policy response and mitigation targets. More than half the population is being hammered financially, psychologically and socially unnecessarily.

The panicked Australian political leaders and public health experts (sic)

Most of the population of Australia remains in a COVID19-related lockdown that is unjustifiable by any measure. I wonder if any of those people bring facts into their thinking process? To give an update, here are three charts. I have shown data for Australia, UK and US.

First, the number of new cases:

Next, the proportion of those new cases that are of the Delta variant:

Finally, the numbers of deaths:

The increase in new cases in the UK and US winter of 2020/21 also resulted in an increase in deaths. But the increase in the current northern hemisphere summer has resulted in no increase in US deaths and a marginal increase in UK deaths. What changed? Delta. Virtually 100% of the current new cases is Delta. Last northern winter, virtually none of the new cases were Delta. Delta is more transmissible (apparently) but dramatically less deadly.

Meanwhile, Australia locks everyone up.
