I work in IT, among people who deal with algorithms, solve complex logical problems, are generally what I would consider intelligent and educated (at least within their field).
Yet nevertheless, from the conversations I've had, it is apparent that very few of them have given ANY critical thinking to receiving this vaccine. About a quarter of them have already received it in some form, the other half have either signed up or thinking about it. I haven't even heard a single doubt articulated in the sense that this is a highly experimental medical intervention which even the manufacturers themselves refuse to stand behind.
People really put blind trust in mass consensus and 'institutions'. If it's on TV and talked about all the time, surely the 'experts' have deemed it safe and it can do no wrong.
