This doesn't mean it's harmful does it?
That said I wonder what the public health officials are trying to achieve here. Are they trying to encourage the largest number of people to be vaccinated, in the hole of slowing down the transmission? Or are they trying to just use a non-nuanced language ("everyone") in order to convey authority and avoid accidentally seeding doubt? Because if it's the latter, I don't think that works with the present generation. The more you push things the less people trust you. I guess things were different 80 years ago or so, but today people have lost trust in buricracy and totally trust the first lunatic they can find online. Is it hopeless?
