@sally because vaccines protect you from disease, and it's one of the best studied things in medical science???

this is like saying 'why should i trust that when i wash my hands between operations it actually does any good'

because there are pathogens that if we do not protect ourselves from them, we can and will get and spread them. in the modern era, the most likely one is going to be either covid or possibly RSV/flu -- all 3 have vaccinations available to varying degrees of up-to-date-ness

'big pharma' prefers that you be an antivaxxer and you instead of getting vaccinated and protected from covid that you get permanent kidney, heart or other damage, so that you can get put on the medication treadmill.
