One of the victims was 40 year old John Heathco, a computer engineer by trade who was identified by Geert Vanden Bossche as "my right-hand man in all my writing about the evolutionary dynamics of the SARS-CoV-2 pandemic."

The Doomsday Prophecy of Dr. Geert Vanden Bossche

A Belgian virus expert has scared the Internet by claiming the COVID-19 vaccines will doom humanity. No need to panic.

Dr. Geert Vanden Bossche is a veterinary doctor who also has a Ph.D. in virology. His LinkedIn profile lists several jobs in upper management positions, including a three-year stint as the senior program officer for vaccine discovery at the Bill and Melinda Gates Foundation. He is no stranger to vaccines. His academic publications essentially stop in 1995, except for one 2017 article about his natural killer cell vaccine idea published in a journal belonging to a publishing group, OMICS Group Inc, that has been called “predatory” and was sued by the Federal Trade Commission for deceptive practices.

Geert Vanden Bossche Stokes Fear of COVID-19 Vaccine To Promote His Own Flawed ‘Solution’

Perhaps no more tired a trope exists in the world of faux cures than the "I have found a problem that no other scientist in the world has thought of and only my untested and unproven cure can stop it" gambit. Vanden Bossche has been able to avoid allegations of peddling such a cure — at least in the credulous anti-vaccine community — because his resume legitimately includes stints at companies or initiatives involved in vaccine development, including The Bill and Melinda Gates Foundation. Since 2014, however, he has been trying (apparently unsuccessfully) to develop his so-called universal vaccine. A company claiming to develop such a product is currently registered to an address identified on Yelp as his veterinary practice.

Vanden Bossche's scientific argument in broad terms is that the current COVID-19 vaccines, through a mechanism analogous to antibiotic resistance, will create mutant variants of the virus that escape the protection of those vaccines. This problem will be exacerbated, he claims, because people who have been vaccinated (and/or social distancing and staying inside during the pandemic) will be less capable of fighting off those strains than someone who has not been vaccinated. As we explain below, this scenario is speculative, scientifically flawed, logically inconsistent, and belied by actual data.

Looks like Vanden Bossche's assessment was spot on.
