It's more complicated than that. Most scientists do not set out to willfully participate in bullshit. They do honest work within the constraints of their profession.

As an example, take covid antibody studies. It is interesting and useful to learn how covid vaccines elicit antibody production. OTOH, the immune system is not limited to antibodies. Extrapolating long-term immunity conclusions from an antibody study is unwarranted. Alas, the scientists performing antibody studies don't have the resources to perform long term studies. This creates an over-abundence of antibody studies, which are cheap and likely to produce measurable results. These studies are then used as incontrovertible evidence that 'science says' there is no such thing as natural immunity, and even if it were, vaccines are much better.
