Same as washing hands (Score 1)

For those who work dealing with public directly or indirectly (ex.: preparing/serving food), vaccination should be seen as a health precaution like washing hands. It is not an option, it should be mandatory. Mary Mallon (1869-1938) was a cooker and typhoid carrier. She killed 53 people with typhoid just by preparing their food. Nowadays, vaccinated cookers doesn't represent this kind of threat.
