That conferred immunity to smallpox. Which makes it about as "different" as Omicron is to Delta or COVID19.
In any case, Cowpox is case-positive proof of animal reservoirs of smallpox.
Sure, that's fair.

Huh? No, it isn't.
UK eradicated Rabies. I'm pretty sure we all agree Rabies has substantial animal reservoirs, right?
So... small, mostly deforested island countries may have a good chance against animal-borne viruses that have inexpensive edible vaccines.
The wealthiest country in the world hasn't managed to eradicate rabies. Covid isn't going to end this way.
There's a lot of diseases we've eradicated. Surely something will come along that you don't have an excuse for.
Leprosy is bacterial and treated with antibiotics. Same with bubonic plague, if that was next on your list.
I believe COVID19 continues because we have a ~60% vaccination rate in the USA, which is far below the needed vaccination rate to slow down the spread of the disease.
A lot of these other diseases brought up have substantial 95%+ vaccination rates, or treatments that can hamper the spread.
No disease is equivalent to another. Smallpox and Measles had much higher spread R0 / replication rates. Others are bacterial. Cholera is water-borne and solved with other methodologies.
It seems unlikely that many cows caught smallpox, given the prevalence of cowpox. Cowpox is a different disease, and was the first vaccine, after which the very concept of "vaccination" is named. Milkmaids had long been known for their immunity to smallpox. If smallpox had been in cows, milkmaids would have been known for universal smallpox exposure instead.
> I'm frankly more flabbergasted that people don't even know the history of diseases
Not a good look.
