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.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '55 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* At least 55 years of age\n* Has phone number\n\nExclusion Criteria:\n\n\\- Not part of the experiments registered under protocol IDs 223749 or 172020'}, 'identificationModule': {'nctId': 'NCT04870593', 'briefTitle': 'What Works to Get the Elderly Vaccinated Against COVID-19?
