> I tend to group those vaccines that confer herd immunity and “others”

A little ironic after making a plea that the world is “filled with shades of grey”

> ought not be the same as the word for those that are intended to confer herd immunity.

> If we used two words, the problem of anti vaxx would be partially ameliorated it seems.

Doubt it. Even after Covid the major anti vaxx issue remains childhood vaccines such as MMR.
