Croker-Buque et al. 2016 [46] | 5 (41) | Children and adolescents, OECD countries, April 2008 – November 2015 | Reminder and recall systems. | There is some evidence of positive effects of reminder and recall systems when targeted at disadvantaged groups, but universal systems have no effect on health inequalities. | 22 (low) |
Menzies and McIntyre 2006 [47] | 7 (17) | Indigenous children and adults; search timeframe unknown, Australia, United States, Canada | Funded vaccination (for Hepatitis A and B and pneumococcal disease) for indigenous children and adults, either targeted or part of the universal programs. | Immunisation programs reduce disease in indigenous populations and reduce racial disparities.
