If routine vaccination was re-started, the Modified Vaccinia Ankara – Bavarian Nordic strain would probably be used, it's a two-dose intramuscular injection, same scheduled as the Moderna vaccine, and is approved in the US under the name "Jynneos". No scarring either, I would assume. In an emergency, ACAM2000 is a single dose and there's a lot of it, so it would be used in people who's immune system is good enough.
I got the vaccine in the military, the needle isn't bad, it looks like a tiny lobster fork. The worst part about it is how the injection site turns into a dime-sized itchy blister that you can't scratch for a few days.

It's not bad at all. Post 9/11 I had it done as a part of a trial on diluting the vaccine (result: you could).
At the time it was just a shading tattoo needle.
5 points, 3 jabs. It was nothing.
...and a complex procedure:
https://www.cdc.gov/smallpox/vaccine-basics/who-gets-vaccina...
> A droplet of ACAM2000 is administered by the percutaneous route (scarification) using 15 jabs of a bifurcated needle. ACAM2000 should not be injected by the intradermal, subcutaneous, intramuscular, or intravenous route.
