Unfortunately not really, I am working on a paper I hope to send off for peer review by June. A search of glycoprotein 41 and 120 for both HIV and separate search for Covid will be pretty illuminating. The last 20 years or so they have been developing vaccines to target those two envelopes because they are so unique and site specific to the virus as a means of creating a vaccine. It wouldn't just appear in nature like that especially on the same parts of the virus. But yeah a lot of our vaccine research and tax payer dollars has gone to vaccines that target those two specific GP's and what do you know happens to be on the brand new"zoonotic" virus.
