First of all science is needed to study most things including diseases and this is so since the study of diseases would require a research organism of course and this is any creature that scientist would use to study life and so without science this would not be possible as science allows for the study of animals and humans which are likely to be vectors and diseases requires epidemiology which are scientific disciplines similar to biology to better understand the disease processes and so science is definitely needed.
