There is not an “enormous majority”, even in the relatively vaccine-hesitant US, that opposes vaccine mandates; there is, on recent polls, within the MoE of 50% that opposes a general adult mandate, and only a minority that opposes slightly narrower mandates attached to participation in most significant public activities.
In Germany, the subject of the story, support for a general mandate was in the high 50s a month ago and around 70% now. Opposition is a rapidly shrinking minority.
