I leave vaccination up to the parent and the doctor. At the same time I do ask parents to let me know if there is anything different about which ones they are not giving or if they changing the schedule so I can be more aware of letting them know things their child might have come into contact with. The MMR is one that concerns me because of the danger to my other parents that might become pregnant should this child get Rubella. But at the same time I delayed many for my own kids based on the different schedules between provinces and the rationale for them. I always opted for the older age when possible giving the system longer to mature before injecting extra things to deal with so it was MMR at 15 m not 12m for instance. Most of the extra things either didn't exist when mine were little or were so new I didn't feel comfortable with them and obviously used to cost back then since they weren't part of the routine.
