Unraveling the origin of SARS-CoV-2 with the scientific method
Although the SARS-CoV-2 coronavirus may originate from zoonosis in the wild, there is also a possibility it began with a lab accident in Wuhan. It is crucial to investigate the exact origin of this virus, in order to make all efforts for such pandemics not to happen again.

Letter to the European Commision
We wrote to the European Commission in March 2022 to suggest three series of actions regarding COVID-19 origin. First, the European Commission could create a commission on COVID-19 origin. Second, it could establish a transparency framework relative to documents and items of information related to the origin of the pandemic within all plausible hypotheses, including research-related and research-unrelated ones. Third, it could encourage research on the first COVID-19 patients in Europe.

Rebuttal Letters challenging the exclusive focus on the zoonosis hypothesis
Several researchers sent letters to various journals to alert that the origin of the coronavirus was not definitively proven to be zoonotic and that a laboratory accident was a plausible hypothesis that should be investigated. Some of these letters are listed in this PDF. None of them was published in a scientific journal, either because they were explicitly rejected, or because they were not considered for publication.
Correspondence to Pr. Shi Zheng-Li
On 11 June 2021, I emailed Zheng-Li Shi with a list of scientific questions. As of 28 Feb 2022, she has not replied. Mentioned by RFI (article in Chinese).
