Omicron = endemic COVID?

[nzoomed]

This presentation includes some potentially good news regarding the COVID19 Omicron variant:

This confirms what many have been already saying, covid19 is now endemic and is just going to become your new strain of the regular common cold.
It will still be worse than the common cold, but with each mutation its only going to get weaker and weaker, while at the same time becoming more contagious.
This is what the experts were even saying right back near the start of the pandemic. This can be seen with the spanish flu, its still in circulation (albeit a weaker strain) to this very day and likely most of us have had it at some point in our life.

I'm a bit dubious about "Dr" John Campbell...

So am I.    More than dubious.   From Wikipedia:

"In November 2021, Campbell said in a video that ivermectin might have been responsible for a sudden decline in COVID-19 cases in Japan. However, the drug had never been officially authorised for such use in the country—its use was merely promoted by the chair of a non-governmental medical association in Tokyo, and it has no established benefit as a COVID-19 treatment.[3] Meaghan Kall, the lead epidemiologist for COVID-19 at the UK Health Security Agency, said that Campbell was confusing causation and correlation. Further, Kall said that there was no evidence of ivermectin being used in large numbers in Japan; rather, she said it "appears this was based on anecdata on social media driving wildly damaging misinformation".[3]"

Note he said "might", I dont think that can equate to him saying it was the reason.
He also did a video about a mutation to the virus discovered in Japan that was affecting the viruses ability to reproduce effectively.
He has always provided sources to all the material he discusses on his channel.
