My 11 year old GD had the BCG injection (TB) as a very young baby as she was born in East London, where there is still a high risk of getting TB. My GS, aged 7, was born in Hertfordshire and hasn't had the innoculation.
All four of us siblings were innoculated at age 13. We lived in Inner London but I believe it was fairly routine in most parts of the country at that time. It seems that nowadays it is only given routinely if there is a higher incidence of TB in the area.
