I’m still trying to understand all that.He's got that pretty much backwards. ADE results from inefficient antibodies that can bind to a virus but not inactivate it. The antibody coating shields the virus somewhat from other aspects of the immune system and the cells that engulf the bound virus, expecting it to be incapacitated, serve as another pathway for viral replication that is underneath the radar
Using only select fragments from the spike protein, as the mRNA vaccine does, is thought to make antibodies that are ineffective against the live virus MORE likely
This stuff gets confusing.
