My upper left arm scar wasn't made by TB vaccine though, it was Rubella vaccine. I didn't associate it with aftereffects of the vaccine itself, it was the unique method of delivery - an airgun instead of a needle. Never seen that before or since.

The MMR vaccine doesn’t cause that type of scar. I’ve found nothing saying air vaccination guns do either.

Smallpox and TB vaccines both do though.

Perhaps you got a combo?

They made a big deal of it, our entire elementary school got it at the same time. And they specifically said it was for German Measles, I don't think MMR had been invented yet. This would have been before 1970.

If pre 1970, you almost certainly got the smallpox vaccine too. At that time it was still an active problem and working to be actively eradicated.

As far as I can tell, German measles vaccine doesn’t cause a scar anymore than MMR (it’s a sub component).

I don't know why they would have hidden the fact that smallpox was included, anti-vax wasn't a thing at the time. But I'll admit the possibility.
