Science has not proven that the virus exists. They also have not proven that it doesn't exist, e.g. By finding that there were other causes for the COVID claimed deaths. We do know for certain that:

1. We cannot count cases [PCR is known to be inaccurate]

NYT: 90% of ALL people who have been labeled “COVID cases” are not COVID cases

2. There is no proof of the virus - And if you haven't proven the existence of the virus: How can you test for it? How can you vaccinate for it?

They didn’t isolate the virus

So far, Science has not proven that the virus exists, and even If they do, they do not know how many people have or had it.
