I see 2 separate theories; (1) It was created at the lab and was released. (2) It was a natural occurring virus being studied in the lab and was released. I see many providing evidence that it was not created and that if true makes theory (1) unlikely. Is there any info that refutes the possibility of theory (2) that it was a natural virus being studied in the Wuhan lab and somehow got released?
Look at my previous post on covid-19 which includes more info
Watch the video interview with Prof Petrovsky an Australian virus expert who has been funded extensively over many years by the USA NIH and developed successsful vaccines for Ebola, MERSs and animal SARs.
His covid-19 vaccine research indicates covid-19 looks too well adapted to human transmission to be a natural virus and it is unusual it has no better animal host prior to arriving at the human stage.
In any event you will see he says that the way many leading researchers have said it is impossible that covid-19 to be man made or man enhanced is strange and disregards lab recombination methods that are well known and leave little or no trace of human intervention
The video interview is a good summary of the facts about covid-19
Its worth reading the text related to the youtube video interview with Prof Petrovsky (much more than is quoted below)
Professor Petrovsky, who is the Chairman and Research Director of Vaxine Pty Ltd, said COVID-19 has genetic elements similar to bat coronaviruses as well as other coronaviruses.
Flinders University Professor Nikolai Petrovsky has completed a scientific study, currently undergoing peer review, in conjunction with La Trobe University in Victoria, which found COVID-19 was uniquely adapted for transmission to humans, far more than any other animal, including bats.
Professor Petrovsky, from the College of Medicine and Public Health at Flinders University who has spent the past 20 years developing vaccines against pandemic influenza, Ebola and animal SARS, said this highly unusual finding left open the possibility that the virus leaked from a laboratory.
“It was like it was designed to infect humans,” he said.
“One of the possibilities is that an animal host was infected by two coronaviruses at the same time and COVID-19 is the progeny of that interaction between the two viruses.
“The same process can happen in a petri-dish. If you have cells in culture and you have human cells in that culture which the viruses are infecting, then if there are two viruses in that dish, they can swap genetic information and you can accidentally or deliberately create a whole third new virus out of that system.
“In other words COVID-19 could have been created from that recombination event in an animal host or it could have occurred in a cell-culture experiment.”
Professor Petrovsky was originally modelling the virus in January to prepare a vaccine candidate. He then turned his attention to “explore what animal species might have been involved in the transmission to humans” to understand the origins of the virus - and had a “surprising” result when none were well-adapted.
“We found that the COVID-19 virus was particularly well-adapted to bind to human cells and that was far superior to its ability to bind to the cells of any other animal species which is quite unusual because typically when a virus is well-adapted to an animal and then it by chance crosses to a human, typically, you would expect it to have lower-binding to human cells than to the original host animal. We found the opposite so that was a big surprise,” he said.
