They speculate on the delivery mechanism in this whole series, but the notion that they are, in some manner or another, giving people synthetic venom peptides, has not been debunked in the least. In fact, the instant and seemingly artificial backlash and outrage against Peters makes me think he's onto something. I think this is exactly what the "vaccine" is, a mixture that makes humans create venom-like peptides, which they can then also shed.

The "he's giving <invented label for your perceived in-group> a bad name" comes across as a new form of SJW "how dare you" outrage.
