Nobody should have been trusting science to begin with. Maybe it will help to show science-believers that they should be more cautious.

What's the alternative? What should one trust instead?

No one. This world is radically subjective and all appearances are deceiving. Even solipsism doesn’t work because you can’t trust yourself!

We live in Cartesian radical subjectivity - and no cogito to save you from the evil demon.

Evaluate risks and benefits as best you can, informed by whatever science seems to show. Life's complicated and nobody can provide simple correct instructions on the right way to do everything, or even anything. Public health messages are an attempt to do that but they're unreliable and sometimes intentionally misleading or wrong because their purpose is to influence people's behavior, not to be correct.
