children do get Prevnar (pneumococcal vaccine). I think it's free now in Ontario. Check your child's vaccination record if he has already had it when he is young (2 month, 4 month, 6 month and at 12 month)
It is free in BC too but actually I am now in HK and want to know if 肺炎鏈球菌針 means pneumococcal vaccine, if yes, then i dont have to worry about that because both of my kids were already had it.
