Well, if we want to go deep into her body of research we can. She's pro-immunization, but doesn't believe vaccines as we know them are an effective way to do so. The current structure involves harming the body in order to create immunity, and therefore, if no benefit is derived, violates the Hippocratic oath.

I get frustrated with her sometimes, because her ideas are incredibly rational and coherent, but she doesn't understand presentation or how to sell an idea.

I would recommend her book if you want to gain an understanding of the rationalist arguments against modern vaccination:

It's controversial thought, but it is enlightening, especially if you want to understand why some "otherwise" smart people believe this nonsense
