Its 90% of all those eligible for vaccination. IMO eventually even the very young will also be vaccinated as trials continue and show they are safe for the under12s.
Anyway the anti-vax morons are not children under 12 but rather low intelligence adults like the ones that post their rubbish on this forum.
They will bear the brunt of Covid 19 and my greatest sympathy goes to the small number who were sucked in by those posting their potentially deadly misinformation.
