Certain social mobilization activities may improve how well mass vaccination campaigns perform, according to a study published on Thursday in the journal BMC Infectious Diseases.
The study was meant to interrupt the transmission of wild poliovirus in India by improving supplemental immunization activities and routine immunization coverage in areas considered a priority. William Weiss from the Johns Hopkins Bloomberg School of Public Health and his research team examined how social mobilization activities improved the performance of SIAs in India.
The CORE Group, a part of India's Social Mobilization Network, has demonstrated success in improving SIA coverage in high-risk areas of Uttar Pradesh. The researchers carried out secondary data analysis of routine monitoring information and social mobilization activities collected by the CORE Group and India's government.
Weiss and his team employed Generalized Linear Latent and Mixed Model statistical analysis methods to determine which social mobilization activities contributed to improved SIA performance. The study found that the number of mosque announcements carried out most consistently determined improved SIA performance across various measures of performance. The number of Bullawa Tollies, a practice in which children mobilize mothers to bring their children to be immunized, also improved SIA performance.
The study found that social mobilization activities such as mosque announcements and Bullawa Tollies can improve the performance of mass vaccination campaigns. Weiss and his team said that it was likely that the quality and quantity of social mobilization activities have equal importance and that social mobilization activity quality should be studied in the future to determine vaccination performance.
