Vaxi
Someone advocating for, or imposing, vaccination or biosecurity measures in a coercive or totalitarian fashion, i.e. in a style reminiscent of a Nazi. Plural: Vaxis.
Calling them 'anti-vaxxers' is a Vaxi move. They just don't want this vaccine.

Looks like the Vaxis have taken over media AND government!

The Vaxis don't care about informed consent and will remove freedoms to enforce the experimental therapy.
