Important thread to understand. The only way to prevent infection + transmission of this family of viruses is at level of mucosal immune system. Serum antibody levels are meaningless in this context.

Theoretically, the one workable design for a sterilizing vx Warp Speed should have pushed is a live attenuated virus in a nasal spray…but here’s the kicker, live attenuated virus is very tricky because it can deattenuate and lead to the very infection you’re trying to prevent.
In fact, as @Harvard2H has posited, the very source of Covid may have been the LAV SARS1 vx that UNC was working on that the PLA stole and then botched implementation of.
Covid index case was no later than spring 2019 but possibly even was occurring in 2018, but went largely unnoticed because the attenuated live virus was in the process of mutating itself back to its original form.
You see, attenuated viruses carry the genetic memory of their previous form and attempt to regain their former power. I think this is urge in people too.
