It's feck all to do with politics its main purpose is to encourage people who have not yet done so i. e. the younger age groups who just happen to be the people spreading the virus now to get vaccinated.
It's a public health initiative ffs to try to help control and stop the spread of a virus that kills people, so if that means me spending 30 seconds extra going into Fir Park to show proof of vaccination then so be it, it's not a lot to ask.
No doubt all the anti vaxers, conspiracy theorists, David Icke fans and general fuckwits in society will be up in arms about it, but its about saving peoples lives and learning to live with the virus as it's here to stay, so we need to deal with it.
