Effect of a conditional cash transfer programme on infant up-to-date and timely vaccination


Background Conditional cash transfer (CCT) programmes are one of the strategies to increase vaccination coverage among underprivileged families by conditioning cash transfer to the up-to-date immunisation of children. However, there are gaps in knowledge of its impact on vaccination at the recommended age (timely).

Methods We performed two cross-sectional analyses of secondary data from a retrospective cohort, at the landmark ages of 12 and 24 months, to assess the effect of the Brazilian CCT on the up-to-date and timely vaccination in children born between 2014 and 2016 and resident in the city of Araraquara, São Paulo (Southeast Brazil). The Propensity Score Matching (PSM) was used to balance two pre-defined groups (beneficiaries and non-beneficiaries) according to the profile of socioeconomic and demographic characteristics.

Results From a total of 7386 children within the cohort, 22.2% (1636) were from beneficiary families of the CCT. After the pairing by PSM, the final sample size included in the analyses was 1440 for each group. We found higher up-to-date vaccination coverage, at 12 (92.1%, 95% CI=90.6% to 93.5%) and 24 months (83.8%, 95% CI=81.8% to 85.7%), among the CCT beneficiaries compared with the non-beneficiaries (85.1%, 95% CI=83.2% to 86.9% at 12 months and 73.6%, 95% CI=71.2% to 75.8% at 24 months). The coverage of timely vaccination did not statistically differ between beneficiaries (41.5%, 95% CI=38.9% to 44.1% and 17.4%, 95% CI=15.4% to 19.4%) and non-beneficiaries (40.7%, 95% CI=38.1% to 43.3% and 17.1%, 95% CI=15.2% to 19.1%) at 12 and 24 months, respectively.

Conclusion The study highlights a positive effect of the CCT on vaccination coverage of the up-to-date infant vaccination schedule. However, there was no difference in timely vaccination.
