I read the question of why vaccination with the COVID-19 vaccine is not made obligatory. I think this would be different if fewer people were willing to take the vaccine. Or would this still be the case if virtually nobody was willing to take it? Would governmental measures have been taken to make people go and get one? Is there an objective set of rules what a politician should do in this case?
More generally, if a government announces that measurements (like the possibility to be vaccinated) have been taken for the people's own good and these measurements don't have the effect a government wants (like 70% being vaccinated), can it be made obligatory to comply with the measurements (like making it obligatory to be vaccinated)? Can a new law be introduced in a short term?
