Abstract
Less than 40 percent of Lahore’s residents had received the first dose by September 2021. In this context, Lahore Divisional Administration requested assistance in planning and delivering an efficient data-driven vaccination drive. In response to Lahore divisional administration’s request, we worked with the government to develop a scalable model to vaccinate people en-masse in urban locations.

Experimental Design

Experimental Design
The treatment group has received community and household-level promotion.
Experimental Design Details
The treatment group has received community and household-level promotion. During household-level promotion, trained mobilizers visited households in the catchment area of the treatment vaccination sites, recorded data of the residents, elicited reasons for not being vaccinated, and delivered a pitch tailored to address their stated causes for hesitancy. The mobilizers also recorded vaccination preferences. In addition, the residents were informed of the address and timings of the nearest vaccination site. Social mobilizers visit households in groups. The activity initiation area for the social mobilizers was also randomized using concentric circles around the vaccination site. Mobilizers were allocated either within 1 km of the vaccination site, or within 1-2 km of the vaccination site, or within 2-3 km of the vaccination site.

This social mobilization drive was also accompanied by community promotion. Community promotion in treatment areas involves announcements from mosques, trucks, rickshaws, and community centers, as well as online and offline marketing campaigns. Local community leaders such as district administration and religious leaders were enlisted to encourage people to get vaccinated.
