I'll bring a witness who will video the situation.

I say I've changed my mind, and say "I do not consent."

Then I'll faint.

Witness keeps shooting video.

Legally they cannot vaccinate an unconscious person, esp. with video-witness present.

Keep repeating this every time you are called in.

Wait till the madness passes over and vaccine passport are overruled in courts or people start reacting en masse to given vaxx and they are recalled.

Just play time.

Or admit you for mental illness and pump you full of drugs because you're a ward of the state.

Plus the worst part of this scenario... Is what would they do with those poor goats?
