The particular vaccine (MVA-BN / Imvanex / Jynneos) that has been shown to be effective for monkeypox is administered via injection[1] not scarification. Stored frozen, it has an approved shelf life of 36 months[1]. In 2014 the US had 24 million doses stockpiled[2]; As far as I can tell, the stockpile is around 1 million doses now[3].
There are also 100 million doses[3] of the scarifying (ACAM2000) vaccine that hasn’t been studied for monkeypox; Stored dry, that has an approved shelf life of 18 months[4]. It is not currently clear to me how much of the stockpile is beyond its expiration date.
If the FDA requires EUAs for the expired vaccines[5], how long that regulatory process will take and how useful vaccination will be by that point are open questions.

For over a year now, making full use of my body has been a big hobby. To this end, I am learning silly human tricks. It has taken a few weeks of sporadic effort and I am now able to snap my fingers consistantly. My next goal is to be able to whistle. I have made little progress so far and am not yet able to whistle particular notes. Previously successful projects of this type were refining my senses of smell and temperature. Now I can reliably tell the temperature of water or air to the degree C with a range of roughly −20 to 45C. Calibrating my sense of temperature was easy enough; I would feel something, guess the temperature, then read off a thermometer. If I was wrong, I might say something like “Oh so that’s what 23 degrees feels like.” and then feel it again.
Other ongoing projects of this sort are to smell relative humidity and to sneeze only in the presence of a bright light. I’ve lost a bit of progress since last thread, now darkening my field of vision works to prevent a sneeze, but I still sneeze occasionally at normal indoor room brightness. When I feel like sneezing I look at a bright light until I either sneeze or stop feeling like I need to. It could be that the CFL I normally use is not bright enough for my purposes. “Hazards of Light” by Cronly-Dillon et al. suggests that I would be safe using a much more intense lamp.
