COVID has become and will remain an endemic disease, like flu. We need to get back to normal. This means getting vaccinated and then living without fear.
Yes, some will get COVID and a few will die, but that applies to almost any infection you can get. DH came close to death last Christmas when he picked up an antibiotic resistant infection when he was in hospital for another reason, my father died as the result of a similar infection.
We will be paying for the economic disruption caused by the pandemic for many decades, probably as long as it took us to pay off all the debt we accrued during WW2, (60 plus years).
Much of what some people see as lack of concern in others is the opposite, it is the conscious decision of other people, once they were vaccinated, to assess the risk and decide life had to go back to normal. In every age group, it is the unvaccinated occupying the hospital beds, and, sadly, a few are dying.
Three weeks ago my DS's family went down with COVID. The children tested positive but were asymptotic. My DDil , who is vaccinated, but has an auto-immune disease, was mainly bed bound for a week, but a week after that was entirely recovered and rushing rund as normal.
This is not a lot different to what is happening with a whole lot of other diseases we are inoculated against. Both my children had all their jabs at children.Both later caught whooping cough and one had measles, despite the innoculation, but the diseases were mild. For whooping cough they both had a slight cough for a few weeks and measles lasted less than a week.
We cannot live our lives in fear for ever. We need each to make our own risk assessments, based on our own risks and who we are. Some people are more anxious, or have reason to be more anxious than others, but look at the number of obese people in the country who know the risks of type 2 diabetes - and probably have it - , heart attacks and strokes, and have a worse prognosis if they do get COVID, yet do nothing to remedy their condition.
