In the first half of the video, Tom Cowan explains the basics of the current PCR bogus "test" and then explains what they are replacing it with. The second half of the video is Q&A on a variety of topics, not about PCR but still interesting.
Bottom line: First generation of bogus tests claimed to find a specific genetic sequence, which was never proven to come from any "virus," and then PCR was used to multiply the material to claim positive/negative. Completely, 100% bogus.
The second generation of bogus tests is going to pretend to find MULTIPLE "viruses" in anyone, and then they will claim that the person needs multiple vaccines for each of those fake pathogens (none of which were ever found in any real "virus").
I didn't watch the video but something Dave on X22 makes me wonder about...
He mentions with some regularity about a new test out in December and it'll show it's been the flu all along loosely implying game over.
I believe a new test, but don't believe it will be any better for humanity.
Regardless, I've had one test my Dr requested before prescribing me an antibiotic for my almost seasonal sore throat last year. That will also be my last.
