Do you think Renesmee can get sick or get a disease?

I am not really sure. There's plenty of reasons why she may or she may not, mostly why not. Being half-vampire and having almost every ability a full vampire has, she may be too strong and perfect to become ill. Or she may have an extremely strong immune system and can beat a bad germ before it can even effect her. On the other hand, Renesmee's body is partly human with her blood and beating heart, so maybe she can catch the flu or a stomach virus or something like that. Diseases like cancer or leukemia, I highly doubt she can get. Well, that's the best answer I personally can give you on that one. Hmmmm....

I think she can but vary rarely does she get sick and no diseases

I am a big reader of books, including the Twilight series. Sapherequeen's theory on why Renesmee cannot get sick is quite flawed. If you read Breaking Dawn during Bella's training, Bella gave Renesmee a rock to try to smash it. Renesmee had no luck with this. Right now is not at the climax of her abilities since she is young. Meaning in theory Renesmee is more closer to her mortal side at her young age than her invincable immortal side. So since she is at the moment weaker than the average vampire there is a larger posibility that she can get sick or a disease DURING her growing process. I cannot be as positive when she becomes an adult. This has been an answer from TheWiseRaven. Farewell

I think. But I;m not too sure. I would imagine she could, because she has a heart beat. But I dont know. Thats a good question actually! Im stumped!

she probably cant because obviously she is half vampire. she is more vampire than human. she has a little more strength than humans, hard pale white skin, and drinks blood. theres a possibility that she can during her stages of being younger. :/ its hard to say.

Maybe when she's younger or when she's growing up but when she turns the physical age of 18 she can not get sick or a get a disease
