- Description: He spent decades as a scientist and executive at Pfizer, only later realising that vaccines are a moneymaking scam, that everything he thought he knew was a lie, and that he'd been working inside the belly of the beast. He regrets all of it.

[Mike Yeadon](https://drmikeyeadon.substack.com/) is a former Vice President and Chief Scientific Officer for allergy and respiratory research at Pfizer, where he spent 16 years developing new medicines before founding his own biotech company, Ziarco. 

With a PhD in pharmacology and over 30 years in pharmaceutical research, Mike became one of the most prominent voices challenging the official Covid narrative.

He was amongst the first credentialed scientists to call out the government's "lethally incompetent" scientific advice, arguing that lockdowns were based on flawed PCR testing that produced massive numbers of false positives. 

[How the whole world fell for the Covid PCR fraudPCR was never designed to test for viruses or diagnose disease, yet everyone, everywhere, fell for it. The man behind it was Christian Drosten — he designed the protocol the whole world adopted, got rich, and is now living the high life.![](https://storage.ghost.io/c/c7/82/c7826764-1091-409a-ac4a-3cdf32a7a528/content/images/icon/Grungy-logo-small-32f9a54b-f38d-4308-b8a3-3da6fb5aa802.png)Jerm WarfareJerm![](https://storage.ghost.io/c/c7/82/c7826764-1091-409a-ac4a-3cdf32a7a528/content/images/thumbnail/drosten-87cb08e9-45db-4add-8cac-fceb94da0489.jpg)](https://www.jermwarfare.com/how-the-whole-world-fell-for-the-covid-pcr-fraud/)

Mike consistently warned that the so-called "second wave" was fabricated through dodgy testing protocols, pointing out that respiratory deaths in late 2020 were actually lower than in previous years. His outspoken criticism of the experimental Covid injections—which he argued were "toxic by design" and failed to prevent illness or transmission—led to widespread censorship across social media platforms.

Mike has a [Substack page](https://drmikeyeadon.substack.com/p/transmission-failure) where he includes the last two centuries of failed clinical attempts to show human-to-human transmission of any pathogen. It's worth a look.
