Vaccinate Early and Vaccinate Broadly: On the health and Economic Effects of COVID-19 Vaccines
Abstract Recent progress in COVID-19 vaccination campaigns has provided real hope for people around the world to successfully end the pandemic, decrease fatality rates and lift social distancing rules for timely economic recovery. Even though several RCT and single-country case studies have shown the high efficacy of the developed vaccines, little is known about how vaccination will result in lower cases and higher economic activity at the macro level. Quantifying the speed of these effects using observational data is of great relevance for policymakers as they grapple with decisions on vaccine distribution and equity, costly containment and social distancing measures, healthcare planning and expenditures, and macroeconomic policy support. With this article, we aim to contribute to the pandemic literature by measuring the effect of vaccination rates on new cases and macroeconomic activity indicators using daily real-world observational data from 314 regions/states in 17 countries. Our results show that: (i) vaccination has a delayed containment effect which increases over time; (ii) the effects on changes in economic activity are transitory after large initial rises—that is, vaccination has permanent level effects; and (iii) the effect of the second vaccine dose is only present for new cases while being insignificant for economic activity.
