Weird and wonderful incentives encouraging people to get vaccinated

Scientists typically estimate that an inoculation rate of at least 70% is needed for herd immunity - where entire populations are protected against a disease. Some bodies and community groups have turned to a weird and wonderful range of incentives in order to get people jabbed. For instance, New Jersey has launched 'Shot and a Beer', a scheme offering a free beer to those who get their first dose in May. To claim a drink, all they have to do is turn up to a participating brewery with their vaccination card.
