biological and geographical issues for vaccine development for diseases caused by protists (e.g. malaria, chagas' disease) have been much less successful than for bacterial or viral diseases. discuss at least one reason for this fact. please include resources. thank you

In reference to the biological and geographical issues that prevent breakthroughs in vaccine progress for protists in comparison to bacterial or viral diseases, the issue stems from the fact that according to recent research that has identified evidence that "protists" have a far greater degree of diversity than any other eukaryotic kingdom, which makes it extremely difficult to develop the necessary vaccine to treat chronic diseases. This problem is juxtaposed by the fact that this diversity is bolstered by a phenomenon that is unique to protists, which is the fact that biologists have discovered that many "protists" are far more closely related to members of other eukaryotic kingdoms than to their own kingdom. This is counter to the norm as by definition, members of a living kingdom should be more like one another as opposed to resembling members of other kingdoms.
