Whether you get reimbursement for preventative vaccinations depends on the cover you have chosen:
You trip and fall on your face. A piece of your tooth breaks off. The dentist suggests putting a crown on the broken tooth. This costs €695. If you have Comfort cover and no excess, you will receive a reimbursement of €475.
You have yourself vaccinated against the flu. This flu jab costs €20. If you have Comfort cover and no excess, you will receive a reimbursement for the total costs.
