OK. The DIRECT source of information, which is a ridiculously huge list. How about-
Sources could be (direct links to): autopsy reports; clinical studies, peer-reviewed medical studies, empirical evidence of various forms (medical textbooks, medical journals, death records, census, vital events registry, hospital records, disease registry, insurance records, population surveys, vital records, research papers).
Sources should not be: sharing a website's (that is known to spread misinformation and lies) "take" on a medical study, a tweet made by a rapper who claims her cousin in Barbados was sterilized by the vax, a YouTube video made by a junior accountant who did and "efficacy study" on masks and proved they don't work, personal anecdotes that are taken as representing the national population.
Avoid bias and potential skewing of information, and post a link to the proof itself.
Kind of like not accepting a manufacturer's review of their own amplifier as being the "best in class". There MIGHT be a bias there. Just like there might be bias at the
www.earthisflat.com website. It's highly unlikely they would post empirical evidence that proves Earth is indeed not flat.
Fair?
