It's a moot point as I'm sure it will never happen, but I'd be in favour of vaccines being mandatory for everyone without a valid medical reason for having one. In the absence of that I see nothing wrong in making things difficult for the anti vax brigade to go about their business by introducing vaccine passports for international travel, festivals, theatres, nightclubs etc.
I'm sick of hearing people in their twenties bleat on about the risk being greater than the reward for them as they won't get that ill from it. Yeah, you're probably right, you won't, but by not being vaccinated you are allowing the virus to hop from one person to another and the risk of a further mutation increases with every hop, increasing the likelihood of it either reaching a stage where it DOES affect them or, more likely, reach a stage where it can get past the vaccine which will put us right back where we started from.
It's a case of taking a tiny risk for the greater good, and some of the poor little flowers think it's too much of a risk for their precious little selves.
I love it when they claim it wont be a problem for those in the 18-30 bracket, because that's a crock of shít. The infection figures do nothing to support that theory. And WTF are they going to do now with the increasing infection rate of the Indian variant?
