Simple access to immunization services does not necessarily translate into uptake of services. In Timor-Leste, key determinants of the success of vaccination efforts are health workers' attitudes, the manner in which patients are treated, aspects of service organization, adequate supply of vaccines, and caregivers' basic knowledge about immunization.

Timor-Leste is a very young and developing nation state. Endemic infectious disease and weakened health security coupled with its growing and inclusive public institutions keep Timor-Leste fragile and in transition on the spectrum of state stability. The objective here is to systematically review Timor-Leste's state and public health successes, showing how a fragile state can consistently improve its status on the continuum of stability and improve health security for the population. The case study follows a state case study approach, together with a disease burden review and a basic description of the health portrait in relation to Timor-Leste's fragile state status. Disease burden and health security are directly proportional to state stability and indirectly proportional to state failure. Timor-Leste is a clear example of how public health can feed into increased state stability. Our discussion attempts to describe how the weak and fragile island nation of Timor-Leste can continue on its current path of transition to state stability by increasing health security for its citizens. We surmise that this can be realized when public policy focuses on primary healthcare access, inclusive state institutions, basic hygiene and preventative vaccination programs. Based on our review, the core findings indicate that by

The outbreak highlighted gaps in the immunity against measles. The National Committee for Control of Disease Outbreaks ensured a coordinated response which led to prevention of deaths from measles due to early case management with vitamin A supplementation, and high measles immunization coverage.
