If you know a guy who knew a guy that you heard died of covid - or the vaccine, that isnt proof. Its second hand, or anecdotal evidence.
Does it mean its false? Not neccessarily, but can you present any medical data from the specific case that it was true?
Saying that people suddenly developed late stage cancer after receiving the vaccine is most likely a pure coincidence. A lot of people are diagnosed with stage 4 cancer that didnt even know they were sick. 50% of us will develop some form of cancer during our life.
Anyone whining about big pharma is a complete hypocrite. Every one of us has no doubt received medical attention in our lives - perhaps for chronic, ongoing health problems. Guess where all your creams, pills, medications etc come from?
If you said 'Big Pharma', well done!
As to the question of 'did they help'? That really hard to answer. If someone got sick, maybe they would have been sicker without the vaccine. Sometimes people have bad reactions or allergies to vaccines, they probably didnt feel so good. Vaccinated and un-vaccinated people still got sick.
Do seatbelts save lives? Yes, but its not guaranteed.
