Abstract: During the COVID-19 pandemic, governments offered financial incentives to increase vaccine uptake. We evaluate the impact on COVID-19 vaccine uptake of cash equivalents versus being entered into lotteries. We randomly assign 1628 unvaccinated US participants into one of three 45-second informational videos promoting vaccination with messages about (a) health benefits of COVID-19 vaccines (control), (b) being entered into lotteries or (c) receiving cash equivalent vouchers. After seeing the control health information video, 16% of in iduals wanted information on COVID-19 vaccination. This compared with 14% of those assigned to the lottery video (odds ratio of 0.82 relative to control: 95% credible interval, 0.58–1.17) and 22% of those assigned to the cash voucher video (odds ratio of 1.53 relative to control: 95% credible interval, 1.11–2.11). These results support greater use of cash vouchers to promote information seeking about COVID-19 vaccination and do not support the use of lottery incentives.

Abstract: How to allocate COVID-19 vaccines is one of the most important decisions currently facing governments. With limited supplies, what is most pressing is deciding who gets priority in the vaccine allocation rollout. Some governments are exploring allowing private purchases of COVID-19 vaccines. Many countries are debating whether COVID-19 vaccines should be mandated. There is little evidence on what policies are preferred by the global public. Our survey of 15,536 adults in 13 countries confirms that priority should be given to health workers and those at high risk but also, to a broad range of key workers and those with lower incomes. The public favors allocating COVID-19 vaccines solely via government programs but was polarized in some countries on mandatory vaccinations.

Abstract: How does the public want a COVID-19 vaccine to be allocated? We conducted a conjoint experiment asking 15,536 adults in 13 countries to evaluate 248,576 profiles of potential vaccine recipients that varied randomly on five attributes. Our s le includes erse countries from all continents. The results suggest that in addition to giving priority to health workers and to those at high risk, the public favours giving priority to a broad range of key workers and to those on lower incomes. These preferences are similar across respondents of different education levels, incomes, and political ideologies, as well as across most surveyed countries. The public favoured COVID-19 vaccines being allocated solely via government programs, but were highly polarized in some developed countries on whether taking a vaccine should be mandatory. There is a consensus among the public on many aspects of COVID-19 vaccination which needs to be taken into account when developing and communicating roll-out strategies.

Abstract: Governments are considering financial incentives to increase vaccine uptake to end the COVID-19 pandemic. Incentives being offered include cash-equivalents such as vouchers or being entered into lotteries. Our experiment involved random assignment of 1,628 unvaccinated participants in the United States to one of three 45 second informational videos promoting vaccination with messages about: (a) health benefits of COVID-19 vaccines (control) (b) being entered into lotteries or (c) receiving cash equivalent vouchers. After seeing the control health information video, 16% of in iduals wanted information on where to get vaccinated. This compared with 14% of those assigned to the lottery video (odds ratio of 0.82 relative to control: 95% credible interval 0.57-1.17) and 22% of those assigned to the cash voucher video (odds ratio of 1.53 relative to control: 95% credible interval 1.11-2.11). These results support greater use of cash vouchers to promote COVID-19 vaccine uptake and do not support the use of lottery incentives.

Abstract: We implemented a clustered randomized controlled trial with 7,227 residents in six rural Ghana Districts to determine whether financial incentives produce substantial increases in COVID-19 vaccine uptake. Villages were randomly assigned to receive one of four video treatment arms: a placebo, a standard health message, a high cash incentive ($10) and a low cash incentive ($3). Non-vaccinated subjects, assigned to the Cash incentive treatments had an average COVID-19 vaccine intention rate of 81% compared to the 71% for those in the Placebo treatment arm. Two months after the initial intervention the average self-reported vaccination rates for subjects in the Cash treatment were 3.5% higher than those for subjects in the Placebo treatment (95% CI: 0.001, 6.9 P 0.03) - 40% versus 36.5%. We verified the vaccination status of subjects: in the Cash treatment arm, 36.6% of verified subjects had at least one dose of the COVID-19 vaccine compared to 30.3% for those in Placebo - a difference of 6.3% (95% CI: 2.4, 10.2 P 0.0001). For all three outcomes, the low cash incentive ($3.00) had a larger positive effect on COVID-19 vaccine uptake than the high cash incentive ($10.00). There is no evidence of spillover effects of the financial incentives that depress the vaccine uptake of subjects in non-financial treatment arms nor of non-treated proximate residents.
