Improved childhood immunization coverage using the World Health Organization’s Tailoring Immunization Programmes guide (TIP) in a regional centre in Australia

Abstract As vaccine hesitancy and decreasing immunization coverage have been identified by the World Health Organization as global alarming health threats, it is of crucial importance to exploit the potential offered by digital solutions to enhance immunization programmes and ultimately increase vaccine uptake. We have previously developed and published a conceptual framework outlining how digitalization can support immunization at different levels: i) when adopted for health education and communication purposes, ii) in the context of immunization programmes delivery, and iii) in the context of immunization information systems management. The proposed workshop is co-organized by the EUPHA Digital health section (EUPHA-DH) and EUPHA Infectious diseases control section (EUPHA-IDC) and aims at discussing the current AVAILABILITY, USE and IMPACT of digital solutions to support immunization programmes at the international, national and local level, as well as, debating on how technical infrastructures on one side and normative and policy frameworks on the other side enable their implementation. We plan to have a rich set of contributions covering the following: the presentation of a conceptual framework identifying and mapping the digital solutions' features having the potential to bolster immunization programmes, namely: i) Personalization and precision; ii) Automation; iii) Prediction; iv) Data analytics (including big data and interoperability); and v) Interaction; the dissemination of key results and final outputs of a Europe-wide funded project on the use of Information & Communication Technology to enhance immunization, with particular reference to the use and comparative impact of email remainders and personal electronic health records, as well as the results of an international survey conducted to map and collect best practices on the use of different digital solutions within immunization programmes at the national and regional level; the firsthand experience of the United Kingdom NHS Digital Child Health Programme which developed, implemented and is currently evaluating a number of solutions to increase childhood vaccination uptake in England, including an information standard and information sharing services developed to ensure that the details of children's vaccinations can be shared between different health care settings the perspective and experience of the European Centre for Disease Prevention and Control (ECDC) for Europe and of the World Health Organization (WHO) for the global level of what has worked so far in the digitalization of immunization programmes around the world, what recommendations were developed and which barriers identified at the technical normative and policy level Key messages Digitalization has great potential to support immunization programmes but its practice and impact need to be measured. Country-level and international experiences have created qualitative and quantitative evidence on the effectiveness of digital intervention aimed at increasing vaccine uptake.

The Impact

AbstractIntroductionThe world is not on track to achieve the goals for immunization coverage and equity described by the World Health Organization’s Global Vaccine Action Plan. In India, only 62% of children had received a full course of basic vaccines in 2016. We evaluated the Intensified Mission Indradhanush (IMI), a campaign-style intervention to increase routine immunization coverage and equity in India, implemented in 2017-2018.MethodsWe conducted a comparative interrupted time-series analysis using monthly district-level data on vaccine doses delivered, comparing districts participating and not participating in IMI. We estimated the impact of IMI on coverage and under-coverage (defined as the proportion of children who were unvaccinated) during the four-month implementation period and in subsequent months.FindingsDuring implementation, IMI increased delivery of thirteen infant vaccines by between 1.6% (95% CI: −6.4, 10.2%) and 13.8% (3.0%, 25.7%). We did not find evidence of a sustained effect during the 8 months after implementation ended. Over the 12 months from the beginning of implementation, IMI reduced under-coverage of childhood vaccination by between 3.9% (−6.9%, 13.7%) and 35.7% (−7.5%, 77.4%). The largest estimated effects were for the first doses of vaccines against diptheria-tetanus-pertussis and polio.InterpretationIMI had a substantial impact on infant immunization delivery during implementation, but this effect waned after implementation ended. Our findings suggest that campaign-style interventions can increase routine infant immunization coverage and reach formerly unreached children in the shorter term, but other approaches may be needed for sustained coverage improvements.FundingBill & Melinda Gates Foundation.

Measles Incidence

Background: According to the World Health Organization (WHO), Indonesia is one of the ten countries with the most significant number of measles cases in the world. Immunization coverage in Trenggalek Regency has reached the target of prevention of measles in the elimination stage, namely measles immunization coverage> 95%, the incidence of measles persists and increases in the last three years, from 2013 to 2015. Purpose: This study aimed to evaluate the trends between measles immunization status and the provision of vitamin A with the incidence of measles in Trenggalek Regency. Methods: This type of research is an observational study with a cross-sectional study design. The sample population is consist of 14 sub-districts in Trenggalek Regency. Data was taken from the health profile of Trenggalek Regency in 2013, 2014, and 2015. In this study, data processing were analysed by Health Mapper application version 4.3.0.0 with product version 4.03 to determine data descriptively. Results: Distribution of measles incidence with immunization coverage in Trenggalek Regency in 2013, 2014, and 2015 showed that measles incidence tended to increase followed with the decreasing number of measles immunization coverage each year. Ironically, the distribution of measles incidence with vitamin A administration in 2013, 2014, and 2015 showed the incidence of measles had increased because of the inconsistent amount of vitamin A administration. Conclusion: Measles incidence tends to occur in low immunization coverage areas and has decreased from the previous year. Giving vitamin A does not prevent the occurrence of measles, but serves to reduce compilation.

According to the World Health Organization, researchers estimate that the spread of vaccines has allowed worldwide life expectancy to increase by 30 years in the past two centuries. Despite these advances, there are major challenges to be overcome to expand immunization coverage. Currently, the Unified Health System (SUS) offers a total of 19 vaccines that protect against more than 40 diseases free of charge. Therefore, the objective of the study was to study and analyze the current state of Brazilian vaccination in relation to infectious diseases eradicated in the country. For the development of the work, data from the Ministry of Health, published scientific articles in the Google academic, SCIELO and PubMed databases, epidemiological bulletins, as well as relevant studies and reports published on websites and internet portals through the descriptors, vaccination in Brazil, vaccination delay in Brazil, vaccines available in the single system were used (SUS). Through this work, it is concluded that the lack of information in a set of other factors generates the non-vaccination of the population, resulting in the return of previously eradicated diseases.

Abstract Despite the enormous benefits of vaccination, global immunisation coverage progress has stalled and remains suboptimal in many countries. In this commentary, we review the recently published update of the World Health Organization and United Nations Children’s Fund Estimates of National Immunization Coverage. We highlight trends in which, despite substantial gains made in improving immunisation coverage at the global level, there remain numerous challenges with reaching and sustaining optimal coverage. We contextualise the trends by exploring plausible supply- and demand-side root causes. Based on these, we stress the need for targeted, context-appropriate strategies for reaching and maintaining optimal immunisation coverage.
