Million-dollar lottery prizes, french fries, paid vacation days, ammunition and even cattle — as countries around the world seek to turn an important corner in the Covid-19 pandemic, governments and corporations are encouraging people to get vaccinated with an array of giveaways.

Vaccine hesitancy in individuals takes many forms, including a fear of side effects, skepticism about their efficacy and the misguided belief that the coronavirus does not pose a significant danger to health. Initiatives to increase vaccine uptake are not surprising, even in countries where denialism is relatively low. In the UK, where acceptance rates remain high, one recent study published in The Lancet found that around 10% of British adults have said that they will never take a Covid-19 vaccine, or will avoid doing so for as long as possible.

Many of the announced schemes aim to reboot ailing economic sectors, such as tourism, hospitality and retail, and to boost worker morale. Earlier this month, the Russian airline Aeroflot launched a dedicated program for flight and cabin crew, offering each fully vaccinated employee one additional paid vacation day.

In New York, vaccinated members of the public can claim a free serving of french fries from the gourmet burger chain Shake Shack, as publicized in an excruciating video featuring Mayor Bill de Blasio. Other food and drinks companies jumping on the bandwagon include Krispy Kreme, White Castle, Nathan’s Famous, Budweiser and Sam Adams.
