Covid-19 result of crazy experiments at Wuhan: Russian scientist

In an interview to Russian daily Moskovsky Komsomolets, translated in a report by the UK-based Daily Mail, noted scientist Professor Peter Chumakov said, "They did absolutely crazy things, in my opinion."

He said the Chinese scientists created "variants of the virus without malicious intent", possibly aiming for an HIV vaccine.

The statement comes even as Russian President Vladimir Putin's government has been warning against conspiracy theories which claim that coronavirus is laboratory-engineered.

Chief researcher at the Engelhardt Institute of Molecular Biology in Moscow, Chumakov in the interview, however, said that the picture of the possible creation of the current coronavirus is slowly emerging.

Scientists at the Wuhan Laboratory, he said, have been actively involved in the development of various coronavirus variants for over 10 years.

"Moreover, they did this, supposedly not with the aim of creating pathogenic variants, but to study their pathogenicity," he said.

According to the microbiologist, there are "several inserts, that is, substitutions of the natural sequence of the genome, which gave it special properties."

"For example, inserts in the genome, which gave the virus the ability to infect human cells. Now all this has been analysed... The Chinese and Americans who worked with them published all their works in the open (scientific) press," Chumakov said.

However, the academic, who is also connected to Russia's Federal Research Centre for Research and Development of Immunobiological Preparations, said it was too early to blame anyone.

After an investigation is initiated, new rules will be developed that regulate the work with the genomes of such dangerous viruses, he said.

Earlier, Veronika Skvortsova, head of Russia's Federal Medical-Biological Agency (FMBA), and Putin's ex-health minister, was asked on Russia's Channel One if the pandemic virus could be manmade.

"This question is not that easy. It demands a very thorough study. None of the versions can be ruled out," she had responded, adding, "We can see that a fairly large number of fragments distinguishes this virus from its very close relative, SARS. They are approximately 94 per cent similar, the rest is different. I think that we must conduct a very serious research."
