This is a comment from a blog post here - https://respectfulinsolence.com/2021/08/11/physicians-who-promote-covid-19-and-antivaccine-misinformation-should-lose-their-medical-license/ it contains a list of references on the origins of SARS-CoV-2, probably leaning towards supporting a natural origin Joel A. Harrison, PhD, MPHsays: August 12, 2021 at 2:46 pm @ Kay West You write: “would you buy a car that only worked 42% of the time (or have an airbag or seat belt that worked 42% of the time).” Actually seatbelts only prevent deaths and serious injury by approximately 50%, so a bit better than 42%. And seatbelts and airbags have caused some injuries, e.g., burst bladders, bruised kidneys, and at least one death, belt twisted and sliced into driver. So, only 50% and small but real risk of serious adverse events. I guess you would recommend against mandatory seatbelt laws and even advise against using them? As for the origin of COVID, not really important, given the huge diversity of coronaviruses in bats, some genetically close to SARS. The evidence is quite strong not from lab; but whether from lab or nature, the world and especially the U.S. were poorly prepared and some nations, especially the U.S. did a poor job of acting. And several reviews tell us that if another, perhaps more dangerous virus emerges, we are still ill-prepared. And by the way, there have been numerous leaks of gain-of-function viruses from U.S. labs, including, you guessed it, a couple of leaks of corona viruses. I realize that nothing will change what you choose to believe; but below is a partial list of the articles I downloaded and read on origins of COVID.
