H5N1. Avian flu that people have been worried about for decades. There is a vaccine for it, but, of course, low stocks because because it was not mammal transmissible until recently. Minks and cows are known to have caught it. It’s believed to still only be transmissible through ingestion. Given current food practices, it could enter the US food chain similar to ecoli.

  Forgive me, I may be spreading incorrect information. I’m not sure the source I’m quoting, could be that the vaccine I’ve heard mentioned is not for humans? I’ve been hearing rumor of herds of cattle being put down to prevent the spread. Could also be that the current outbreak doesn’t have a good candidate yet. Wikipedia seems to think there was a human H5N1 vaccine approved in 2020. https://en.m.wikipedia.org/wiki/H5N1_vaccine https://en.m.wikipedia.org/wiki/H5N1_vaccine

    Rich countries may well have stock of H5N1 vaccine following the dangerous situation in the 00s. For now it's believed that the antibodies those vaccines induce would be somewhat useful against the current virus, at least one could hope they will prevent disaster until an updated vaccine can be developed and deployed. A couple of example articles here (Probably abstract only unless you're hooked up with a good library. Sorry!): https://www.nature.com/articles/s41591-024-03189-y https://www.nature.com/articles/s41591-024-03189-y https://www.nature.com/articles/s41591-024-03256-4 https://www.nature.com/articles/s41591-024-03256-4 Influenza is an RNA virus and thus less stable and particularly prone to change. I find it somewhat remarkable that the old vaccines are not useless by now, but they're pretty tenuous protection against this problem, so developing better and specific measures against what we're up against now is urgent.
