Every day's a school day ,didn't know thatThe BCG is/was given in a different manner to other vaccinations...its injected under the skin and not into muscle...to deliberately leave a scar. The scar denotes you have had the BCG and if the scar is at least a minimum size it suggests you are immune to TB.
Thankfully due to the TB/BCG vaccination program, most youngsters no longer need it as its pretty much been eradicated....although there was a slight increase a few years ago....but back under control
