- Adjuvants. As a materials researcher I think it's nuts we inject nanoscale alumina in our blood.

- Regulatory structure. Why can't I sue a vaccine manufacturer? Limit awards, if you necessary, but if I cant sue I cant get discovery.

- Effectiveness. The flu vaccine's effectiveness is statistical artifact. See healthy vaccine bias

- Historical effectiveness. I had a civil engineer smugly point out that his profession had ended more diseases than biology. So I looked it up. Civil engineering did more to end communicable diseases than vaccines.

- General dishonesty of the medical profession. I don't expect my Advil to be 100% safe; I don't expect my vaccine to be either. I dont expect my medical health officers to lie about it though (see mRNA and the long dismissed myocarditis risk)
