It’s not necessarily the individuals who are worried about getting it themselves, I’d imagine it’s trying to reduce the risk to others including loved ones
We live in a strange world at the moment. A high majority of people are/will be fine now they’ve been jabbed, however, there are still vulnerable and higher risk people that need to be protected where possible
I live a pretty normal life (going to football, out every weekend etc) however, even now I’d change that in advance of seeing my mum who is higher risk, as well as LF testing beforehand etc
