International scientists renew call to investigate source of coronavirus, this time with Plan B

Thirty-one international scientists signed an open letter on June 28, reiterating their call for a “comprehensive investigation into the origin of the coronavirus” and asking the Chinese government to participate in the investigation. The open letter suggests that without the cooperation of Beijing authorities, the source of the coronavirus Covid-19 could be found through a science-based alternative plan (Plan B).

The open letter was published by French newspaper Le Figaro on June 28. The scientists stridently called for a thorough investigation into the source of the coronavirus and said, “if possible, with the involvement of the Chinese government.”

In the open letter, the scientists specifically asked for unrestricted access to all relevant documents, samples and personnel in China and, if necessary, elsewhere, according to Le Parisien.

The letter also states that they note that the so-called WHO “investigation” in China earlier this year was neither led by WHO nor was it positioned as an investigation.

Plan B

This is not the first time that scientists have publicly called for a full traceability investigation of coronavirus (Covid-19), but unlike other open letters, this one proposes a “Plan B” that says that some sort of science-based “alternative” could be developed without the cooperation of the Chinese authorities. “In fact, the letter was signed by a number of people who had been involved in the virus.

In fact, the scientists who signed the open letter believe that it is possible to bypass the Chinese authorities by examining “a large amount of highly relevant information” outside of China.

According to Virginie Courtier, a genetic evolutionary geneticist at the French Academy of Sciences (CNRS) and one of the signatories of the open letter, “what needs to be done is to thoroughly check all international databases for original or deleted virus sequences, and not just to look for them in the databases owned by China. “Contrary to the claims of many in the scientific community, we believe that a thorough examination of the origins has a good chance of success”, she said.

S protein

Ms. Cour-Thier told French journalist Yang Mei on June 29 that what struck her as most bizarre was that much of the important information had not been released to the public. For example, the S protein entry point, Wuhan virus laboratory likely already knew, but why not announced to the public? And they deliberately kept the news about the entry point in the announcement.”


On June 12, 2021, Dr. Tedros Adhanom Ghebreyesus, director general of the WHO (World Health Organization), said that the families of the millions of people who died from coronavirus (COVID-19) “should know the source of this virus so that we can prevent it from happening again,” according to Le Figaro.

In line with this desire, the G7 leaders issued a joint statement the day after Tandse’s speech calling for a transparent, timely, expert-led, science-based phase II study on the origin of coronavirus COVID-19, convened by WHO and conducted in China as recommended by the expert report, the newspaper said.
