Question: 

when I was a child in grade school 1960s nurses came to the school and gave every child a vaccine. It was a circle of needles and it left a big scab and scar for life what was it

Answer: 

In BC, there are 2 live vaccines that you may have received in the past where a scab would form after vaccine being given and leave a scar at the injection site.

Smallpox [Vaccinia] Vaccine: After smallpox was eliminated from the world, routine vaccination against smallpox was stopped because it was no longer needed.  In BC, we stopped giving smallpox vaccine in 1980. The smallpox vaccine was given by a special technique that caused a blister which formed a scab and when the scab fell off, it left a scar (usually in the deltoid area of the upper arm).

Bacille Calmette-Guérin (BCG) Vaccine: The BCG vaccine is not currently recommended for routine use in any Canadian population. In BC, the BCG vaccine was discontinued for health care workers in the 1970s and in 2003 the program was discontinued in BC First Nations communities.The BCG vaccine is given intradermally (under the superficial layers of the skin) that forms a papule (small raised swelling) or ulceration (sore on the skin in 50% of people) that leads to a scar (usually in the deltoid area of the upper arm).
