AS TCW reported yesterday, the regulator MHRA has approved the Pfizer Covid vaccine for children as young as 12. Originally, it was argued that vaccines were needed to protect children against severe Covid. However, even the most ardent pro-vaxxers now recognise that the illness poses only a tiny risk to children, so they’ve adopted a new strategy: they claim that we must vaccinate children to achieve herd immunity against SARS-CoV-2. This claim reveals a shocking ignorance about the virus.
Here’s the simple fact: we will never achieve full herd immunity against SARS-CoV-2.
The most important thing to remember is that none of the present vaccines confers sterilising immunity; in other words they do not prevent infection or the ability to transmit the virus; they only protect against severe cases. Both the regulatory agencies and the vaccine manufacturers admit this. This is because the vaccines do not produce mucosal antibody responses in the airways. Thus, we have a significant number of ‘breakthrough cases’ in double-vaxxed subjects, including seven members of the New York Yankees who recently tested positive after being fully vaccinated.
Thus, even if we vaccinated everyone on earth with the present Covid vaccines, we would not achieve full herd immunity. The virus would still spread between people, and those with weak immune systems, including the elderly and those with comorbidities, would continue to develop covid from time to time.
But let’s imagine that scientists developed a vaccine that did confer something like full sterilising immunity. We might be able to hunt down human clusters of Covid, but what are we going to do with the animal reservoirs of SARS-CoV-2? According to the US Centers for Disease Control (CDC), the following animals can be infected with the virus: cats, dogs, voles, ferrets, fruit bats, hamsters, mink, pigs, rabbits, raccoon dogs, tree shrews and white-tailed deer. So, are we going chase down all the domestic and wild animals around us and vaccinate them?
Smallpox is the only virus that humanity has fully eliminated from the world. We were able to do this because it infects only humans (i.e. it has no animal reservoir), and we have a smallpox vaccine that confers full sterilising immunity. We have not been able to eliminate any of the other viruses for which we receive regular vaccinations. Even polio still exists, despite a 32-year vaccination campaign, despite a nearly perfect vaccine, and despite the fact that polio does not infect other animals.
So let’s face it: complete herd immunity is a pipe dream. So is ‘zero Covid’ or full elimination of the virus. Any attempts to achieve these things will cause massive economic harm and involve severe violations of human rights and individual freedoms. And they will fail.
