We set up a macroeconomic epidemiological (SIR) model to evaluate the role of vaccination in the interactive dynamics of COVID-19 and the economy. We analytically examine the existence and local stability properties of the four steady states and find strong support for a locally stable interior equilibrium where the economy grows in the continued presence of the pandemic. We also find that it might be possible to attain a pandemic-free economic revival only if the rate of recovery from infection is faster than a threshold level. We examine, both analytically and numerically, the impact of various types of policy interventions, including non-pharmaceutical interventions involving restrictions on economic activities (like lockdowns and travel restrictions) as well as speeding up the rate of vaccination. We find that under reasonable parameter configurations, a combination of large-scale vaccination as well as non-pharmaceutical interventions are required to meet the twin objectives of controlling the pandemic and reviving the economy.
