Top Russian expert has claimed that scientists at Wuhan laboratory did 'absolutely crazy things' to alter the coronavirus and enabled it to target humans.
Professor Petr Chumakov, considered an expert in the field, said that the Wuhan Laboratory team was actively involved in the development of various coronavirus variants for more than 10 years, possibly in the name of HIV vaccine research.
He, however, said that their only aim was to study the pathogenicity of the virus and that there was no malicious intent behind the study.
Prof. Chumakov said that in his opinion they did crazy things like inserting in the genome, which enabled the virus to infect human cells.
'There are several inserts, that is, substitutions of the natural sequence of the genome, which gave it special properties,' he said adding that it was interesting that the Chinese and Americans who worked with them published all their works in the open scientific press.
