Vaccinations and Spread: The Dangerous Myth That Vaccinated People Don’t Spread Covid-19

Confirmation of reality: Extensive spread even if vaccinated.

A new study shows the Delta Covid-19 variant produced similar amounts of virus in vaccinated and unvaccinated people if they get infected.

CNN Health: July 2021

Note that once infected, the amount of virus is similar. This does not mean that spread is necessarily the same within a vaccinated group as within an unvaccinated group, as depending on how the ambiguous ‘infected’ is interpreted, there may be less risk of being ‘infected’ when vaccinated, and it is also possible that similar amounts of virus many not result is similar infectivity.

It is still most likely that being vaccinated reduces spread, but what is becoming clear is that reduction of spread appears far from elimination of spread. Given the delta strain is twice as infectious as the original, then unless being vaccinated means less than half the risk of spread following vaccination, a fully vaccinated population would experience as much spread of Covid-19 delta variant, as occurred within unvaccinated populations and the original virus.

People should still get vaccinated as it will massively reduce their own risk, and it still will like reduce the risk of spread to others, but being vaccinated is not a panacea or reason to abandon other measures.

We Know Elimination of Spread is a myth, but many pretend or even lie anyway.

There Is Clear Data on Spread Amongst Vaccinated.

While it is only recently we have studies showing just how infectious vaccinated people can be, it has long been clear that being vaccinated will not necessarily block infection. Examples of people being aware of the reality include the case of the UK health secretary, who under the rules for the UK went into lockdown despite having tested positive to Covid-19 despite being fully vaccinated. Note that the UK prime minister Boris Johnson, initially was going to not isolate despite being a close contact of the health minister because Boris Johnson is not only fully vaccinated but has also famously been previously infected, but Boris Johnson was forced to ‘backflip’ and go into isolation as scientific advice was that he could still not only be infected but also spread the virus.

Yet there are commercial interests that promote the fairy tale that “vaccinated people won’t spread the virus” because it can allow commercial activities that clearly, when facing reality, are life threatening if allowed on a large scale. Vaccine passports promoted as suggesting holders need not quarantine is just one example.

No Where has Herd Immunity been Achieved, despite vaccinations and case numbers.

Government Policy Based On Myths Could Be Tragic.

The Dangers of Subscribing To The Myth.

Unlike the myth of Santa Claus, where it can be said that telling people things you know are not true can be benign and yet make them happy, this myth is definitely dangerous.

The national news program last night declared that Australia would require 80% of the entire population to be vaccinated in order for life to be able to return to normal with the delta variant of Covid-19. The problem is, the data presented clearly completely unreal, and seems to assume zero fully vaccinated people become infected. So what is the reality? The reality is there will be no herd immunity at 80% vaccination levels, just reduced hospitalisations as a result of the vaccinations. Policy tells the population one thing, when reality is another. One people are convinced they cannot spread Covid-19 following vaccination, their behaviour is likely to be reckless. Unlike the Santa myth that is used to encourage good behaviour, this myth can also encourage bad behaviour.

Grattan Institute Report: Simplistic Statistical Lies.

It can seem simple. If in an unvaccinated population the virus spread to 5 people, once 80% (4 in 5) are vaccinated, then the spread will be to 1 person or less. ‘Herd Immunity’. Except this only works if vaccinated people cannot spread the virus. You would think, just weeks after the fully vaccinated UK health minister tested positive and need to in isolation, and his close contact, previously infected and vaccinated Prime Minister Boris Johnson went into lockdown, that thinktanks advising the Australian government would not the vaccinated people can be infected and potentially spread the disease.

In fact, with the UK at around 80% immunity levels once the effects of vaccinations and prior infections are both taken into account, guesswork is not required to see that infection numbers do rise even with 80% immunity, as it is happening in Britain. Herd immunity is not achieved, and the hope is that with sufficient people vaccinated, deaths will be low. However, deaths in Britain with 80% immunity are currently at around 100 per day, so the question as to whether that is ‘low enough’ and other consequences can be tolerated is still to be determine. However, but the time Australia does reach 80% immunity, then there will be more data.

Theoretical model that conflicts with real world data from the UK.

The question is how a group who advise government can predict that 80% will actually provide herd immunity, and that if there are outbreaks, as shown in the news article on 29 July 2021 on abc news, these outbreak would produce only around 10 deaths per outbreak is frightening. The UK has proven that as fully vaccinated people can still spread the virus, herd immunity is not achieved, and case numbers continue with deaths at levels many times those the models being used project.

No more lockdowns, no more capacity limits on venues, and that is the point as well when we can start opening up international borders.

Danielle Wood, Grattan Institute, on ABC news July 29, 2021.

This is a cause for concern, but at least the advice is not to open up before 80% levels, and hopefully by that time wise heads will prevail.

Update 17th August: Finally, Now the ABC also reports Herd Immunity does not appear possible.

Implications for Living With Covid-19.

There are choices as to what future countries aim for:

The problem created by the myth, is that if living with Covid-19 there will be very low rates of infection as everyone is vaccinated. The reality is that all evidence suggests that spread among vaccinated people of the delta strain is at least as prevalent as spread with unvaccinated people of the original Covid-19 virus.

Given that everyone locked down before hospitals overloaded with the original strain, the lower hospitalisation rate means we can expect the delta virus to spread to unprecedented levels with a vaccinated community. The positive news is that the chance of being hospitalised may be reduced by 90% to 95% as a result of being vaccinated.

However, as with the vaccinated health secretary, this ‘immunisation’ is against serious disease, not all disease. So over time, it seems certain everyone will have the disease ten or even twenty times. Which means, back to be hospitalised, although perhaps only after a year or two instead of first time around.

Conclusion.

Sorry, but like the pandemic, it is not over. But I will be trying to add a conclusion to this page soon,
