Inoculate has an immediate effect. So it would be more inline with bleed or force vote and should not be grouped with clear mind or jail who’s effects only happen at the start of the night.
In particular since innoculate has an effect before the start of the night (deflecting a bleed) which both has feedback and changes the result of an interaction it would not be cancelable.
Clear mind on the other hand blocks conversion which can only happen at night. If day conversions were a thing then your point would be valid. But they aren’t so it’s not.
