If you kill somebody you will be charged for involuntary manslaughter or constructive manslaughter depending on what speed limit was but if I sit next to you unvaccinated in a waiting room should I be charged as well?
Are you comfortable endangering those around you because protecting them is an inconvenient imposition on your freedom? That's an entirely different issue.
I'm not against vaccination I'm against mandatory vaccination and limiting my human rights if I don't vaccinate. Nobody will prevent you from visiting a country if you don't use glasses, take antibiotics or anything else you mentioned.
I never visited Africa but I heard there are some security measures regarding Malaria but c'mon forbidding someone to work or travel only because he or she didn't get vaccinated against 1 pathogen is over the top.
