 St. Louis Zoo will require employee COVID-19 vaccinations by end of year

Expect more zoos and aquariums to follow suit, especially keepers working with susceptible animals, such as cats, mustelids, and primates, as well as those under government oversight.  Almost every keeper and curator that I know who doesn't have some sort of medical exemption has already gotten their jab.  Pretty much all of them have done so gladly, doing their part to protect the animals.  This mandate, of course, also extends to all other departments, including visitor services, who are most likely to have direct interaction with the public.
