I know that we eradicated smallpox, but only because there are no animal hosts.
Covid has many animal hosts [0]. You'd have to vaccinate them all to eliminate covid, that includes bats, cats, dogs, primates, deer, etc.
Otherwise covid will keep evolving in animals, and jumping back into the human population, as it appears happened with omicron over the course of about a year in mice [1].
I believe that the parent you replied to is correct, we will not eradicate covid with vaccines.

Come now. I said no such thing. This is straw man.
>"We will not ever eradicate Covid-19 with vaccination" is the most small minded statement possible to make. We have eradicated so many diseases with vaccination
I suppose with a long enough time horizon we may invent some vaccine to eradicate Covid-19, the common cold, and Influenza.
I think what you mean to say is "We cannot eradicate COVID-19 with the current vaccines," but to swear off vaccines as if they can't do the work is frankly, dumb.
