I think the time has come to allow fully vaccinated people to be able to go abroad and attend mass gatherings etc.The ones who choose not to be vaccinated will have to miss out.
This would be very unfair and possibly illegal.
Those under 30 haven't, officially, been offered their first dose in England yet.
I think that's one of the major reasons the government dropped the idea. How can it be right a 60 year old can go on holiday abroad/ to festivals etc and a 18, who faces basically zero risk from Covid, can not?
I don't necessarily disagree with such a system (say, foreign holidays with no quarantine for the fully vaccinated), but it would have to wait until everyone has been at least offered their first and second dose.
