Nongermetic Covid vaccines cause the virus to evolve
The nongermetic vaccine is unable to stop circulation of virus,
but it does reduce severe scenarios, some researchers believe.
But back in 2015, molecular biologists uncovered a disturbing
phenomenon. Some low-quality vaccines, including most
veterinary flu vaccines, not only fail to help the body cope with
pathogenic viruses, but also contribute to the evolution of their
more dangerous forms, according to an article published in the
journal PLOS Biology (

The most contagious strains of avian influenza that mow down
entire poultry farms around the world today can kill an unvaccinated
bird in as little as three days. In the United States and Europe,
infected birds are destroyed, and the virus cannot continue to
evolve. Southeast Asians are instead vaccinating birds with
low-quality vaccines, which could help evolve the flu into more
deadly forms, said Andrew Reed of Pennsylvania State University
in Philadelphia.
Reed and his colleagues found the first confirmation of the highly
controversial and popular among opponents of vaccination idea
that such drugs can accelerate the evolution of disease-causing
viruses in an attempt to uncover the roots of the mysterious
epidemic, the so-called Marek's disease, on chicken farms in the
United States.
This disease, caused by the herpes virus, was a fairly rare guest
on poultry farms until recently, and its appearance did not lead
to massive deaths of birds. Today it is even less common due to
vaccination, which began in the 70s of the last century, but the
virus has become much more dangerous and infection of
unvaccinated birds usually leads to their death 10 days after the
onset of infection. The main feature of the vaccine that farmers
use to protect birds from the virus is that the immunity it produces
is not complete; it does not prevent the spread of the virus from
a protected birds to other chickens.
Such conditions, as scientists said, contribute to the evolution of
extremely dangerous and pathogenic strains of the virus that could
not survive in an unprotected population of birds, as they would
kill them too quickly to effectively spread across the planet.
Reed's group tested this hypothesis by comparing what happened
to the most infectious strains of Marek's virus in vaccinated and
unvaccinated birds. As shown by these observations, the vaccinated
birds released into the environment a large number of viral
particles, which were able to enter the body of chickens from the
control group living in cages nearby, and infect and kill them.
When scientists infected unvaccinated birds with this virus, they
died too quickly for their bodies to begin shedding Marek's virus
into the environment, thereby preventing further spread of the
infection and the development of the virus. This, according to
scientists, shows in practice that poor-quality vaccination not only
does not restrain the spread of infection, but also allows it to
become more dangerous and infectious than is possible under
normal conditions. Thus, mass vaccination with nongermetic vaccines
against Covid-19 contributes to the spread of more and more new
strains of Covid-19.
