With respect to the last paragraph, vaccination is a sticky topic, because the vaccine protects both you and those around you. Vaccines are not 100% effective, don't convey permanent immunity, and not everyone can be vaccinated due to various health restrictions. As a result, if you voluntarily choose not to be immunized when you could otherwise have been, you are voluntarily exposing some people you come into contact with to potential harm. It's up to you whether that falls within your definition of "violence", but some would say so.
