Needs to die? What are you talking about? Obviously administering tests that haven't been shown to be effective prophylactically and can even cause harm to a given population is a stupid idea. That's why we do research and weigh benefits/risks. That's like saying antibiotics need to die because many times they don't work and can cause resistant strains, when the problem is that physicians often administer them incorrectly.

Appropriate preventative medicine supported by research and numbers is so, so important.
