There is no one who is definitively immune to the zombie virus in The Walking Dead. The virus is incredibly contagious and deadly, affecting almost everyone. However, there are a few instances where characters seem to exhibit some resistance or even a complete lack of symptoms.
- The Governor's Daughter, Penny: Penny is shown to be completely unaffected by the virus, despite being bitten by a walker. This could be explained by her young age or some sort of genetic anomaly.
- The Whisperers: The Whisperers, a group of survivors who live amongst the walkers, seem to have some level of resistance to the virus. They wear the skins of walkers to blend in, and they even seem to be able to interact with the walkers without being attacked. This could be due to their close proximity to the walkers or some sort of ritualistic practice.
- The "Cure" Experiment: In the comics, a group of scientists attempts to find a cure for the zombie virus, and they believe they have found a way to create a "cure" by using a specific strain of the virus. However, the cure is not successful, and it only leads to more problems.
While these examples offer some intriguing possibilities, the truth is that the virus is incredibly powerful and there is no known way to prevent infection or cure it. The characters in The Walking Dead are constantly battling the virus and its effects, and there is no guarantee that anyone is truly immune.
