This has nothing to do with the corona virus strains we are currently dealing with, and more importantly, there has never been any credible research proving that Covid was made in a lab. The only paper that got any traction suggested it was non-manipulation based gain of function research, but that was disproved only a few weeks after the paper's release as well. I know we all want to know where it came from, but the odds against us ever having actual evidence of it being from a lab are virtually zero. And no, rejected research proposals do not constitute proof of anything.
There is only circumstancial evidence for it, but it is reasonable to suspect COVID-19 is the result of a researcher getting infected, not noticing, and introducing the virus to the human population. There is no evidence for, and it is very unreasonable to believe it was created in a lab.
