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").
Interesting that this is essentially a 100% copy of the hoax malware popups that claim huge numbers of viruses on your PC to try and entice you to pay for and download a 'cure' that in reality is even nastier malware, typically ransomware.
100% chance that the 'you NEED these vaccines URGENTLY' is just as malicious a payload, and will also be an ongoing extortion effort.
