B5 Shields:

We were using some of the Agents of Gaming material for the B5 mod, and also referring to the tech books. While there really aren't that many examples, some races do have 'shields', most specifically the Vorlon, Abbai and Brakiri (also a few other ancients). The White Stars also have some sort of shield and most large EA ships have an Energy Web (mentioned by both Warner Brothers and the B5 game) that acts as a shield.

Even with this being said, I don't really recall too much shield-like tech in the actual series except with the ancients.
