I do wonder how many unknown side effects less researched vaccines have! And at this point, there is probably a huge research gap between the covid vaccines and all other vaccines.
PS: I am not an anti vaxxer. I paid 500€ to get the damn HPV vaccines and next week I am gonna get my second meningococcal vaccination (one of the most painful vaccinations), because it also provides limited protection against gonorrhea and I want to minimize the chance of me having to take fluoroquinolone antibiotics again despite being sex addicted. Everyone should do their own risk assessment.
