It’s a whole different and horrific issue for cats. It’s also killed at least two whose owners them raw milk. It’s apparently about 67% lethal for cats.

The current flu shot is almost certainly not effective against the current HPAI A(H5N1) strain that is in the news and making life hard for dairy and poultry farms. There likely won’t be a vaccine developed for it unless it mutates to become human-to-human transmissible. Currently, people can only contract it from exposure to sick animals or their environment. As long as you avoid contact with sick birds or cattle (or their bodily fluids or feces) you should be safe from contracting it… unless it mutates.

I’m pretty sure that is Patricia Tallman. She appeared on a number of Star Trek shows. She also played Lyta Alexander on Babylon5.
