Yes, fleas do have immune systems, though they are simpler than those of mammals. Their immune system primarily consists of innate defenses, such as cellular responses and antimicrobial peptides that help protect them against pathogens. Fleas can respond to infections, but their immune capabilities are not as complex as those found in more advanced organisms.

the fleas where the start whom travelled from china, they had a bacteria in them which the fleas where immune to this bacteria was called versinnia. when the fleas bit the rats (black rat's ) drink the blood they would vomit out that bacteria that the rat wasn't immune to... soon the rat would die. after the fleas wiped out all the black rats they had no food so they moved onto the the humans and animals! so technically it wasn't the fleas who caused the plague it was the bacteria versinnia
