Hi, I have older and younger kids. I remember clearly getting reminder letters for immunisations when my older kids were little. It seemed to stop about 15 years ago. Is it just my health authority? We have headlines all the time about low take up of childhood vaccination, surely reminders are a no brainer. I just booked my 4 year olds preschool booster and wonder what the rates of take up are given parents have to remember/ know in the first place?
