Listen here you little shit.

🤔 Yeah, there's also the concerns about making following comments not make sense or appearing to have hidden evidence that I was ever wrong. But a strikethrough can avoid those issues.

BCG definitely did leave a scar. We all had to get vaccinated again (the entire school) when my GCSE art teacher got TB and coughed all over everyone instead of staying at home. I had the skin test that showed I already had immunity, when most of the others had to have the BCG. I remember the nurse making me go behind a screen to take off my shirt so she could check for my BCG scar.

I don't have the scar anymore. But it was there during my younger years.

That's the version that killed smallpox too. Earlier vaccines against it were worse, including some that could give you smallpox, even fatally (but you were less likely to get sick from it than from exposure, and you were less likely to get as sick if you got it from the vaccine than naturally catching it). The vaccine was always controversial, but eventually it became safe enough that enough people became comfortable with it being forced on everyone. This is the first disease we developed vaccination for, and for good reason, it was a gross, painful, deadly, and very infectious disease. If it were still around I'd be first in line for a vaccine even with the blister.

For old USians it's smallpox, for younger people of other countries it's BCG. I was zapped for smallpox in 1964.
