Hello,    My daughter had hers done two weeks ago at 13 months (having waited like you due to the shortage). Was advised that they are being far more flexible on the 1 year window following the shortage.     I would persist with weekly phone calls to your Health visitor until it becomes available. For what it is worth, I did a fair bit of research on this and its value and think it is worthwhile. It is offered in specific areas for a reason and you really cannot predict when or where your little one may come into contact with somebody else with TB.    cONGRATULATIONS ON YOUR NEWBORN BY THE WAY!
