Horns

Jews have been associated with devils and depicted as devil-like throughout history. The New Testament refers to Jews who don't accept Jesus as the “synagogue of Satan” (Revelations 2:9, 3:9). Depictions of devils look like racist caricatures of Jews, racist caricatures of Jews look like devils: horns, hooked noses, evil expressions, scraggly beards, and (historically, usually; currently, among white supremacists) dark/sallow skin. Much of this has to do with bad translations of the Bible contributing to Moses being depicted with horns, fusing with depictions of Satan borrowing from the pagan god Pan. The shooter at the Pittsburgh synagogue The Tree of Life, referenced in Season 2 Episode 3, specifically said "Jews are the children of Satan" on his blog.

And people take the Satanic imagery literally.

These are just two interviews, but there are modern people who still think Jews actually have horns:

I had a friend, Carol Beck, who - when she found out I was Jewish, said to me, ‘You can't be Jewish. You don't have horns.’ I said, ‘What?’ And she said, ‘I was told that all Jews have horns.’ I said, ‘No. I'm a Jew. I don't have horns. Nobody I know has horns.’ (source)

So please, do not depict Jews with horns.

Vampires

This requires some background on why Jews are associated with being bloodthirsty and "blood suckers." It goes back a long way.

Many Christians to this day believe that the Jews killed Jesus, who is the archetypal innocent in Christianity. Because consuming the blood of Jesus is part of the good ritual of the Eucharist in Good Religion, Christianity, Christians imagined that there must be a parallel bad ritual in the Bad Religion, Judaism. These ideas fused in the "blood libel": the belief that Jews deliberately, often ritually, murder innocents. Over and over throughout history, blood libel accusations have broken out, leading to torture (to extract "confessions") and mass murder of Jewish communities.

The story usually says that Jews then consume the blood or even body parts of ritually murdered children, sometimes baking blood into matzah for Passover (nvm that Jews are forbidden to eat blood! "kosher salt" is called that because it's used in the koshering process that removes blood from meat, rendering the meat kosher). Added to this is the idea that Jews are essentially an invasive parasite, greedily leeching off of society as part of the Jewish agenda to destroy all that is good.

So some people believe Jews are literally blood-drinkers; some people believe Jews are metaphorically blood-suckers. The core image is consistent, either way. The depiction of Jews as vampires in modern antisemitic imagery was and is widespread among racists. The 1922 movie Nosferatu (see middle image above) in particular is a good example of the imagery of the Jew directly showing up as vampiric. This is a terrific article about it.

This isn't to say you couldn't do a depiction of a Jew as a vampire thoughtfully, without evoking antisemitic canards. But, like I said in my original post, you'd want to proceed with the same caution with which you'd be depicting any minority in a way that goes with the grain of racist caricature, rather than against it. But going against it is the safer bet. Bringing up how black people are caricatured again, the contrast is between the animalistic, atavistic way black people have been depicted in racist images vs. the cool, suave black vampires in movies like Blacula and Blade. The parallel move for Jewish monsters would be to lean into more macho monsters (especially since Jewish men are often caricatured as weak, sly, and effeminate). We're not a monolith, but a lot of Jews in my notes are fans of werewolf!Robby.
