The vaccination campaign will last six to twelve months. Therefore it is irrelevant who starts 14 days earlier or later.

In the meantime we can already start thinking about the next vaccination season. Will the Covid-19 vaccination replace the flu vaccination in importance? Especially since the distance rules will probably remain in part. There was no recognizable flu wave this winter.
