That's just life. You could get in a car crash everytime you leave the house, could slip on the stairs and break your back, get a cut and get sepsis etc. The whole of life is a what if lottery, this is not some unique thing for covid, life is full of risks but you still have to live it
Covid is far far more prevalent than flu, and Long Covid is more prevalent than post-viral flu complications, I don't know anyone who is off long-term sick at my work with flu issues or indeed in the past few years, but I know several people off with ongoing Covid issues.
This is not the same risk as a car accident or sepsis, because more than a million people have life-changing chronic illnesses in a very short space of time, and the more times you get Covid, and the more the variants change, the more likely this is to happen to you and or your children.
We did not know the long-term consequences of polio years ago, now we do, I'm not crazy about having repeated bouts of a Covid type illness. I've had flu twice in 50 years, my kids have had Covid twice in six months.
Basically you don't think it will happen to you, or your kids. And you are right, that's how we drive, that's how we take other risks- but the risk of Covid is greater than many people on this thread think. I didn't think I'd be affected like I am, but I was and it's life-changing, even Omicron. Sorry if that isn't what people want to hear!
