Summary

COVID-19 poses a substantial risk to elderly populations; understanding how to get elders vaccinated against the virus is therefore a policy priority. An experiment with elders in Tamil Nadu, India will be used to evaluate interventions policymakers might use to raise vaccination rates amongst the elderly. The particular interventions being tested are: calling elders to inform them about vaccination; encouragement of a "buddy system," whereby elders are accompanied to the vaccination site by another adult who could also get the vaccine; and seeding vaccination information with "gossips," individuals who elders identify as being good at spreading information in the elders' communities. The interventions are phone-based, and can be implemented quickly and at low cost. This makes them promising strategies the Tamil Nadu government and other governments could use to vaccinate elderly populations against COVID-19.
