A lot of people are ok with risks, until they’re bitten by them.
There are many articles (I’ve seen two just in passing) where nurses talk about COVID patients going on a ventilator, and begging for the vaccine, only to be told it’s too late.
I feel that most people that are taking risks with COVID (e.g. healthy people not getting vaccinated) either don’t have enough foresight to realize they actually don’t want to be hospitalized/die from this, or they don’t believe the risks are real.
Risk assessment is something many aren’t great at — that is striking a reasonable balance between no fear and too much fear. This is made worse by conflicting opinions and studies, and not being able to discern truth from fiction/sensationalism.
