Mass infection prevention and mass vaccination with leaky Covid-19 vaccines in the midst of the pandemic can only breed highly infectious variants.

Key document on mass vaccination and immune escape. Response to critics. Why do mass vaccination campaigns promote dominance of selective immune escape variants? I repeat with utmost urgency my call for a public scientific debate with the WHO, qualified experts and authorities worldwide. 

First, do no harm




Geert Vanden Bossche (DVM, PhD)

Geert Vanden Bossche received his DVM from the University of Ghent, Belgium, and his PhD degree in Virology from the University of Hohenheim, Germany. He held adjunct faculty appointments at universities in Belgium and Germany. After his career in Academia, Geert joined several vaccine companies (GSK Biologicals, Novartis Vaccines, Solvay Biologicals) to serve various roles in vaccine R&D as well as in late vaccine development. Geert then moved on to join the Bill & Melinda Gates Foundation’s Global Health Discovery team in Seattle (USA) as Senior Program Officer; he then worked with the Global Alliance for Vaccines and Immunization (GAVI) in Geneva as Senior Ebola Program Manager. At GAVI he tracked efforts to develop an Ebola vaccine. He also represented GAVI in fora with other partners, including WHO, to review progress on the fight against Ebola and to build plans for global pandemic preparedness. Back in 2015, Geert scrutinized and questioned the safety of the Ebola vaccine that was used in ring vaccination trials conducted by WHO in Guinea. His critical scientific analysis and report on the data published by WHO in the Lancet in 2015 was sent to all international health and regulatory authorities involved in the Ebola vaccination program. After working for GAVI, Geert joined the German Center for Infection Research in Cologne as Head of the Vaccine Development Office. He is at present primarily serving as a Biotech/ Vaccine consultant while also conducting his own research on Natural Killer cell-based vaccines.

I only take responsibility for the statements and scientific papers that I have published myself. I have noticed these are occasionally being recovered, without my approval or knowledge, by untrustworthy sources with their own agendas or ideologies, both left- and right-wing, by provaxxers and antivaxxers, conspiracy theorists and uninformed and unqualified individuals who are convinced by their own right. I strongly distance myself from this and would like to emphasize that what I am trying to convey goes beyond these beliefs and opinions. They are irrelevant to what concerns us as humans. In fact, they are an obstacle. Above all I want to safeguard my integrity and insist on absolute independence. The response to my appeal should remain only and purely scientific and in no occasion ever be used or abused by any non-scientific rhetoric.  

I would also like to reiterate that I cannot respond to the many questions from people who are hesitant about whether or not they should get the vaccine or the second shot thereof. As far as the vaccines themselves are concerned, I will continue to refrain from making any specific judgement or comparison of those. None of this is part of my ‘mission’.
