It was during our teenage years that all girls had to have the rubella vaccine. A note was sent home for parents to sign and I recall that most of us ended up having it done.
The process involved a test done with about 6 needles, in the shape of a circle, in our forearm. Two weeks later, if there was no reaction we had to endure a vaccination. The few who showed a nasty sore in the area which had been stabbed with needles a fortnight earlier were apparently ‘immune’, and were therefore spared the injection.
