Cross-country health spillovers from vaccine rollouts mean the pandemic will not be over anywhere until it is over everywhere. This column argues that the success of a country’s vaccine deployment in the first half of 2021 was driven by five primary factors: the severity of its pandemic waves in 2020, its procurement strategies, the quantity of locally produced vaccines, the quality of health infrastructure, and vaccine acceptance. Swift and broad administration of vaccines provides a significant boost to health outcomes, particularly in the midst of major outbreaks and accompanied by containment measures.

To increase Covid-19 vaccination uptake, many governments have used, or are considering using, monetary incentives. This column uses an experiment conducted in Sweden to show that a modest incentive of €20 can increase vaccination rates substantially. Furthermore, incentives appear to help increase vaccination uptake in any group, including those socioeconomic groups that are less likely to get vaccinated. However, behavioural nudges, such as providing information or highlighting the social impact of vaccination, do not lead to a statistically significant increase in vaccination rates.
