Parents' decision about vaccination of children is influenced by social relationships and sources of information. The aim of this study was to assess the influence of social capital and trust in health information on the status of Measles-Rubella (MR) vaccination campaign in Tamil Nadu.

Materials and Methods:

This was a case-control study carried out in Kancheepuram district in Tamil Nadu where the MR vaccination campaign offered by Government of Tamil Nadu had poor acceptance. Cases were parents of children who had refused the MR vaccine and controls were parents having children in the same age group who had accepted the vaccine. Data on social capital and trust in health information were collected by using social capital scale developed by the researchers and trust in the source of information was measured by using simple questions on the level of trust in the information source.


Nonadministration of MR vaccine was high among young parents and parents of younger children. Vaccine acceptance was higher when it was offered at school (P < 0.000) and also among parents who trusted school teachers (P < 0.003) and other school children (P < 0.014) as source of information. MR vaccine acceptance was less among parents who trusted social media and WhatsApp information. Greater levels of health-related physical social capital led to greater vaccine hesitancy. Multivariate analysis revealed that greater the age of the child, better parental attitudes toward vaccination, poorer health-related physical social capital, and greater trust in health information provided by school teachers led to overall greater acceptance of the MR vaccine.


Strong homogeneous bonding social capital had a negative influence on MR vaccine acceptance. Schools and school teachers played a vital role in influencing parental decision to vaccinate.
