To stop disruption to education? - kids will still have to isolate if they test positive, close contacts with still need to test. The vaccine does not stop people getting covid (I got covid after being double vaxxed as did dd1). To think the vaccine is going to stop education being disrupted is wrong.
To stop children getting seriously ill? The chance of a child getting very ill from covid is tiny, more chance of them getting ill from flu and more chance of them being hit by a car whilst walking home from school?
To stop the spread of covid? Covid is still being passed between vaccinated people, it may reduce the chance but no one really knows how much?
Many kids have already had covid, they suspect up to 60% so many will have some immunity. We don’t know that a variant might not appear in the near future that will be vaccine resistant meaning the vaccine will be useless, the delta variant already seems to be effecting this who are vaccinated.
I’m not anti vax despite what I have written, I am vaccinated, I have had covid and I’m pleased I was vaccinated, I wasn’t unwell with covid, possibly because of the vaccine but I do believe kids do not need this vaccine unless they have underlying conditions. I have chose not to vaccinate dd2 (for now) but I have nothing against those who decide to vaccinate their kids, it should be a choice.
