In the UK, they are thinking about offering discounts and freebies as a bribe to the unvaccinated. Which will cause resentment in the already vaccinated who get nothing after acting for the public good. And not many will be persuaded by such trifles anyway, we're talking at bribes specifically aimed at younger people - discounts on uber, pizza etc. Of course, some people will go for it - but causing them inconvenience if they don't have it, or rewarding all the people who have had it without having to be persuaded, would be a far more effective strategy.
