Another result was that she (Mary Mallon) was imprisoned/quarantined for the remainder of her life (after being released from her first quarantine and being told not to work as a cook, changing her name, working as a cook, causing more outbreaks and deaths). 23 years...

She refused medical procedures that could have removed the infection (removal of gall bladder) and as such died in imprisonment/confinement.

I'm not suggesting we should lock up anti-vaxxers, but if there is an outbreak of polio then those people who refuse to be vaccinated put at risk those who cannot be vaccinated.
