I wrote this article a few months back, and it mentions 2 studies done on the overall health outcomes of vaccinated vs. unvaccinated.
(a New Zealand study in 1992 & the Kiggs Study in Germany)
We Don't Vaccinate: How Sick has Become the New Normal
Oh, and when you put many "anecdotal" stories today it makes a "Case Study" which is indeed good scientific practice. I would not put much weight into a few stories here and there, but when thousands upon thousand of people are saying almost the exact same thing, that becomes evidence.
The VaxXed Team is carrying out a Case Study of sorts by travelling the country and gathering tons of vaccine injury stories, and now unvaccinated healthy stories from the people eager to share their accounts and finally be listened to and believed.
What do you think about the effect of self selection in collecting surveys?
@canadian-coconut hopefully Steem can do exactly that one day.
If you are looking for a products defects and ways to make it safer or more effective or more appealing to the public,
you have to survey or interview the people who have filed a complaint against the product or refuse to use your product, and take their concerns and experiences seriously.
Collecting these accounts are just one piece of the puzzle, but they are an important piece in seeing the whole picture.
It would be nice if independent non-biased scientists were provided the large amounts of money to fund a variety of types of studies that meets all scientific standards and look at things from all angles ... but until then we have to use our common sense based on what people's experiences are.
