So the regime that we're putting in place here says, "Yes, actually, we should be able to say that there are some things that unvaccinated people can't participate in the same as a vaccinated person, in order to reduce that risk for the whole population." That is appropriate, and that is what this legislation allows for, because unvaccinated people can still spread the virus, they can spread it to children, who can't be vaccinated, and they can spread it to those who are vaccinated, who can then spread it to others. Vaccination turns down the risk of people ending up in hospital, but it's not an absolute guarantee, and, therefore, the more unvaccinated people there are the more risk there is.
