I believe that there should be no obligation (in Maximum America mode that'd imply SWAT kicking in doors, restraining and injecting people), but society and state always manages to provide incentives to do things. Be it making things opt-out (possibly with a small fee), forbidding entry to institutions (e.g. only vaccinated people in schools), or just good ol' looking down on parents who don't vaccinate. For example, in my country there are mandatory check-ups for children every couple years, which include a baseline of vaccination unless opted out. There are also mandatory check-ups conducted in schools (IIRC teeth and also vaccination - interdisciplinary, so to speak).
