“…These coverage estimates are consistent with MR seroprevalence data from the same survey, in which we observed the lowest measles seroprevalence following the MR campaign in Kanpur Nagar District and no change in seroprevalence when compared to the serosurvey conducted in the district prior to the campaign [15]. MR vaccination campaign coverage estimated by other studies ranged between 90.5% in Tamil Nadu to 68.6% in Imphal [6,7,9,14].…”

“…The surveys were conducted from 2018 to 2020 across two age groups (9 months to younger than 5 years and 5 years to younger than 15 years). The goal of each survey was to estimate measles and rubella seroprevalence and to evaluate the impact of the vaccination campaign [15]. This analysis is restricted to children enrolled in the surveys conducted after the MR campaign in the five survey districts.…”

“…All SIAs in these districts were conducted in the later phases of the campaign. Prior publications presented measles and rubella seroprevalence, vaccination coverage, and correlations between routine and campaign coverage [15,16]. In this paper we focus on the data related to the MR campaign from the post-campaign serosurveys, including estimating MR campaign vaccination coverage, identifying factors associated with receipt of the campaign dose and reported reasons for non-receipt of the campaign dose, and explored the effectiveness of the communication strategy in promoting campaign awareness.…”

Background In alignment with the Measles and Rubella (MR) Strategic Elimination plan, India conducted a mass measles and rubella vaccination campaign across the country between 2017 and 2020 to provide a dose of MR containing vaccine to all children aged 9 months to 15 years. We estimated campaign vaccination coverage in five districts in India and assessed campaign awareness and factors associated with vaccination during the campaign to better understand reasons for not receiving the dose. Methods and findings Community-based cross-sectional serosurveys were conducted in five districts of India among children aged 9 months to 15 years after the vaccination campaign. Campaign coverage was estimated based on home-based immunization record or caregiver recall. Campaign coverage was stratified by child- and household-level risk factors and descriptive analyses were performed to assess reasons for not receiving the campaign dose. Three thousand three hundred and fifty-seven children aged 9 months to 15 years at the time of the campaign were enrolled. Campaign coverage among children aged 9 months to 5 years documented or by recall ranged from 74.2% in Kanpur Nagar District to 90.4% in Dibrugarh District, Assam. Similar coverage was observed for older children. Caregiver awareness of the campaign varied from 88.3% in Hoshiarpur District, Punjab to 97.6% in Dibrugarh District, Assam, although 8% of children whose caregivers were aware of the campaign were not vaccinated during the campaign. Failure to receive the campaign dose was associated with urban settings, low maternal education, and lack of school attendance although the associations varied by district. Conclusion Awareness of the MR vaccination campaign was high; however, campaign coverage varied by district and did not reach the elimination target of 95% coverage in any of the districts studied. Areas with lower coverage among younger children must be prioritized by strengthening the routine immunization programme and implementing strategies to identify and reach under-vaccinated children.
