What happens, as we get back to as close as normal as we can, covid becomes like the regular flu only your kids have had the regular flu and have immunity to it somewhat. They have never experienced covid before so their body's immune system doesn't recognise it. By the time their immune system realises it is a threat the infection has set in and reproduced and will make them ill. The vaccine trains their immune system to recognise it and fights it before it gets to infectious in their body.
If they don't have a vaccine, they might not get too ill but the viral load in the body will become much larger where they will breathe more covid out. They will spread it the classroom to all the other kids who all will take it home to their family who in turn will take it to work. It might not make lots of people very ill but it will get to someone who it will kill.
You have every right not to get vaccinated and not to vaccinate your kids.
