This is a topic that comes up seemingly only in the depths of the online photography community. There are surprisingly few resources on the subject that I can find, even though I'm very interested in the topic as someone who identifies as vegetarian (not vegan). I have read the article on the ADOX website (very informative but limited) and the Ilford one, plus articles that rehash that information as well as personal stories of the "I gave up film" and "I struggle with my conscience" varieties.
One of the most interesting resources is this video, which I found via this page.
The person making the emulsion in the video seems to imply that PVA emulsion is viable with appropriate R&D. The comments section under the video includes the suggestion that as some gelatin is made from human hair this could be used instead. Relatedly, this article about human-derived gelatin says the following:
I am not prepared to boycott film but I see the use of gelatin as problematic and I would like to see progress within the industry on this matter. So I would appreciate any detailed resources people could recommend, or any information they have on the subject themselves. I don't have the knowledge or intellectual skills for understanding the technicalities of film manufacture but I do my best to learn about these things.

Scientists are developing a new approach for producing human-derived gelatin in large enough quantities to be a commercially viable replacement for the animal-based gelatins used in all kinds of gelatin-like desserts, candies, and other foodstuffs as well as pharmaceuticals and cosmetics.
