I realize this is old but people could always use the info.
Standard health vaccines are recommended through health canada, many people find vaccines controversial usually because they know someone who had an adverse reaction or heard it 2nd,3rd,4th or 5th hand. Vaccines are drugs and all drugs have adverse effects.
So it is up to you to make an informed decision if the risks outweigh the benefits. Please remember that because you saw 1 person online or a newspaper story on it, it does not mean that it is common as 100's of millions (potentially billions) of people take certain vaccines and their reactions may not be even related.
Anyways here is the info: Immunization Schedules - Public Health Agency of Canada
Table 5 is likely what you want to know about boosters
Table 6 is what you may want to know if you are at a higher risk (most RS population wouldn't be)
Costs depend on where you go to get it:
Clinics = variable
Doctor = expensive
Pharmacy = less expensive
Travel vaccinations I usually go to International Travel Health and Vaccination Clinic, they give you a good idea of what you need WRT vaccinations, drugs and non-drug measures when travelling. As a tip, make sure you have tons of questions before you go so that you get what you pay for. Costs of Vaccines are here
Ask away if you have more questions.
