I'd offer them a hundred quid voucher to get the vaccine, to be spent in this country on anything of their choice. I think it would be enough to get the percentage up considerably and the cost compared to what we have spent so far would be almost irrelevant.Read this morning that only half of men aged 18-24 in the U.K. have come forward to be vaccinated, so I’m not sure whether a carrot or stick approach is required, or a combination of both.
