ontario, canada is free of charge. my daughter had this in grade 7 or 8 (can't remember). if the girls are not taking this shot at school at that time, then if they want to have this later, they will need to pay for the charges.
i had asked recommendations from family doctor and my sister-in-law (reg. nurse in hk), she said it is good for her (she talked with many doctors in her hospital for this before informing me).
