The WHO also serves as a forum for summits and discussions on health issues.
Sure. I bolded the last line above because it has happened with Covid-19 while I and others have posted links to those discussions and research.
Fwiw, I think you are putting the emphasis in the wrong place--There have been some "nutjob" opinions and those are what leads to "skepticism and distrust among the general population." Of course those aren't found in mainstream media (unless newsworthy because a politician or elected official is making those comments) but circulate on social media which have lead to scrutiny to how those companies operate...Fwiw, I think they should be responsible for what circulates on their platforms. Right now they are trying to police themselves and if that doesn't work government will be lobbied to get involved. That's my take.
