alt Hacker News> in the US, public health messaging stated the opposite, in order to keep as many masks in supply to healthcare workers despite a major shortage of masks
So experts also lied about masks!!!
So many people died because of those lies!!!!
They spread misinformations!!!
I'm saying that "experts" here is not one group. The politicians and public figures choosing what information to publicize and disseminate are not the same people as those who worked on developing the vaccines.
