Vaccine mandates for COVID-19

Consider recent vaccine mandates for COVID-19 (for employees in general, healthcare workers, and/or students in public schools or universities) and what issues of social and distributive justice might underlie or challenge these mandates. Under what circumstances can the government implement regulations on different health behaviors? Do you think these are acceptable and legitimate for a government to implement? On what grounds? Is COVID a unique case or no? Why or why not? Apply AT LEAST one ethical theory or moral principle to your argument.
