I’m don’t buy that vaccines don’t work for any virus.
As for coronavirus we haven’t had a successful vaccine.
Now look at the childhood immunization schedule. None of the vaccines are against a coronavirus.
As for other viruses such as polio and smallpox viruses the vaccines have worked well.
And there have been successes in other animals such as the feline leukemia virus vaccine.
Some medicines work some don’t. The Covid vaccines have been a failure but other vaccines clearly prevent disease.
This is due to the fact that these viruses mutate constantly.
Smallpox, polio. These do not significantly mutate and have been targeted by effective vaccines.
Add in the fact that the definition of Virus was changed twice after the Covid shots were created, in order to lower the expectations of a vaccine in order to place the Covid shot in the “Vaccine” category, and you would think this would be a red flag to any person who understands what vaccines are supposed to be.
