In the case of COVID19/SARS2, it looks very likely that a whole lot of 'unprotected science' has been taking place that could have promoted the outbreak. See this long May 5th article in the Bulletin of the Atomic Scientists for a close and careful review of the evidence pointing to the origin of the virus: https://thebulletin.org/2021/05/the-origin-of-covid-did-people-or-nature-open-pandoras-box-at-wuhan/.
For those who may not be aware of this helpful bit of knowledge already, the chemical activity of furin — the human enzyme specifically discussed in the Bulletin of the Atomic Scientists’s article cited here and the enzyme that COVID19/SARS2 virus employs to have its way with your human cells — is very strongly chemically inhibited by chelated zinc and copper.2
