Vaccines. I got my mpox shots because it works across a broad spectrum of pox viruses. The mpox vaccine is actually just the modern smallpox vaccine! Not terribly common, but in the past decade or so, someone found a frozen vial of smallpox in a university lab freezer.

While unlikely that mpox or smallpox will ever completely blow up into a huge pandemic, it is good to have.

I think I could survive a Prohibition for quite some time, and even homebrew and sell it or run a speakeasy.
