Within three to four days, a red, raised and itchy spot develops at the vaccination site. This is a sign of “a take,” which means the vaccine is doing its job. This spot soon turns into a pus-filled blister that gradually gets a little bigger by day 10. Then, it slowly starts to dry out. As the blister heals, a scab develops. This is a normal part of your skin’s healing process. By 14 to 21 days after vaccination, the scab falls off. In its place, a small, pitted scar remains.
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.

Imagine if the covid vaccine did that, we’d still be in lockdown today lmao.

BCG scar, not smallpox.
For old USians it’s smallpox, for younger people of other countries it’s BCG. I was zapped for smallpox in 1964.
