Factors that affect the uptake of community-based health insurance in low-income and middle-income countries : a systematic protocol

Many people residing in low-income and middle-income countries (LMICs) are regularly exposed to catastrophic healthcare expenditure. It is therefore pertinent that LMICs should finance their health systems in ways that ensure that their citizens can use needed healthcare services and are protected from potential impoverishment arising from having to pay for services. Ways of financing health systems include government funding, health insurance schemes and out-of-pocket payment. A health insurance scheme refers to pooling of prepaid funds in a way that allows for risks to be shared. The health insurance scheme particularly suitable for the rural poor and the informal sector in LMICs is community-based health insurance (CBHI), that is, insurance schemes operated by organisations other than governments or private for-profit companies. We plan to search for and summarise currently available evidence on factors associated with the uptake of CBHI, as we are not aware of previous systematic reviews that have looked at this important topic

Healthcare workers’ adherence to infection prevention and control guidelines for respiratory infectious diseases: A rapid qualitative evidence synthesis

COVID-19 spreads easily between people who are in close contact, or through coughs and sneezes. As the number of cases continues to increase, healthcare workers (HCWs) are notably at risk as a result of frequency of contact with suspected cases or infected people. Use of infection prevention and control (IPC) strategies by HCWs is therefore important. We summarise the evidence from a rapid Cochrane qualitative evidence synthesis by Houghton et al. on barriers and facilitators to HCWs’ adherence to IPC guidelines for respiratory infectious diseases.

Role of vaccines in preventing influenza in healthy children

The role of an influenza vaccine is to minimise illness and death. Vaccines provide good protection against influenza strains and significantly reduce time off work. However, the recommendation for use depends on the efficacy, effectiveness and safety of the vaccines. We highlight a Cochrane review that sought to determine the efficacy, effectiveness and safety of seasonal influenza vaccines in healthy children, and provide implications for practice for vaccination of children. The findings suggest that influenza vaccines play a key role in reducing serious morbidity and mortality among children. There were few data available to provide firm conclusions on adverse events. Vaccinating against influenza not only reduces its incidence among children, but also extends these benefits to the unvaccinated population, such as the elderly. In light of the many direct and indirect benefits of vaccinating children aged 2 - 16 years, there is a need to provide access to influenza vaccines to all eligible South African children

Lessons learnt during the national introduction of human papillomavirus (HPV) vaccination programmes in 6 African countries: Stakeholders’ perspectives

Background. Infection with human papillomavirus (HPV) significantly increases the risk of developing cervical cancer later in life. Therefore, globally, HPV vaccines targeted to pre-adolescent and adolescent girls have been on the rise since the licensure in 2006. However, the introduction of HPV vaccines has been relatively slow in Africa. At the end of 2016, only 8 of the 54 countries in Africa were reported to have introduced HPV vaccination at a national level. By 2019, the number of countries had grown marginally to 11.Objectives. To investigate stakeholders’ perspectives on the experiences, challenges and lessons learnt during national HPV vaccine introduction in Africa.Methods. A questionnaire was administered to selected participants from 8 African countries. These countries had successfully introduced HPV vaccination at a national level by the end of 2016. We used in-depth interviews and self-administered online questionnaires for data collection and analysis. Data are presented without naming the country or participants; therefore, readers will not be able to identify the results that are specific to individual countries. Narrative and thematic reporting were used to describe the results.Results. We obtained results from 6 of the 8 targeted countries. The challenges reported during HPV vaccination programmes were: identifying the target population, using a school-based vaccine-delivery strategy, obtaining political support, the need to integrate HPV vaccination with existing school health programmes and engaging multiple stakeholders. These challenges were similar in all 6 countries. The lessons learnt were that a school-based delivery strategy is a successful approach for national HPV vaccination, and that identifying girls for vaccination at schools was less challenging if implemented through a class-based instead of an age-based approach.Conclusions. Most African countries do not have established platforms to deliver vaccines to pre-adolescent and adolescent populations. The successful introduction of the HPV vaccine through school-based vaccination strategies in African countries may have created a platform to deliver other adolescent vaccines. The similarity of the study findings across the 6 participating countries further strengthens the need to document and disseminate the challenges and lessons learnt during HPV vaccine introduction in Africa. Documentation and dissemination of the challenges and lessons learnt are useful to other countries in Africa that plan to introduce an HPV vaccination programme, and possibly other adolescent vaccines.

Human papillomavirus vaccination acceptance and hesitancy in South Africa: Research and policy agenda

Cervical cancer is responsible for one-quarter of a million deaths per year worldwide. In South Africa (SA), cervical cancer is the leading cause of cancer deaths among women aged 15 - 44 years. Human papillomavirus (HPV) vaccines provide a safe and highly effective means to reduce the burden of cervical cancer. The World Health Organization initiated a plan for the elimination of cervical cancer; the programme’s success relies on the introduction and high uptake of HPV vaccines globally. SA introduced a school-based HPV vaccination programme in 2014, but uptake is not as high as expected. Suboptimal HPV vaccination coverage may result from various factors, including vaccine hesitancy. Vaccine-hesitant parents may delay or refuse HPV vaccination for their daughters. Tailored interventions are needed to address this. However, knowledge regarding vaccine hesitancy and policies to address this hesitancy in SA are currently limited. While SA has taken commendable steps in cervical cancer prevention by implementing and financing the HPV vaccination programme, it is imperative that there are clear policies in place to help strengthen the programme. These policies need to clarify areas of uncertainty that may lead to mistrust, and pre-empt factors that will cause hesitancy. Equally important is that local research should be conducted to better understand HPV vaccination hesitancy and other determinants of uptake to further inform and shape national policies

Individual and Contextual Factors Associated with Low Childhood Immunisation Coverage in Sub-Saharan Africa: A Multilevel Analysis

Background: In 2010, more than six million children in sub-Saharan Africa did not receive the full series of three doses of the diphtheria-tetanus-pertussis vaccine by one year of age. An evidence-based approach to addressing this burden of un-immunised children requires accurate knowledge of the underlying factors. We therefore developed and tested a model of childhood immunisation that includes individual, community and country-level characteristics. Method and Findings: We conducted multilevel logistic regression analysis of Demographic and Health Survey data for 27,094 children aged 12–23 months, nested within 8,546 communities from 24 countries in sub-Saharan Africa. According to the intra-country and intra-community correlation coefficient implied by the estimated intercept component variance, 21% and 32% of the variance in unimmunised children were attributable to country- and community-level factors respectively. Children born to mothers (OR 1.35, 95%CI 1.18 to 1.53) and fathers (OR 1.13, 95%CI 1.12 to 1.40) with no formal education were more likely to be unimmunised than those born to parents with secondary or higher education. Children from the poorest households were 36% more likely to be unimmunised than counterparts from the richest households. Maternal access to media significantly reduced the odds of children being unimmunised (OR 0.94, 95%CI 0.94 to 0.99). Mothers with health seeking behaviours were less likely to have unimmunised children (OR 0.56, 95%CI 0.54 to 0.58). However, children from urban areas (OR 1.12, 95% CI 1.01 to 1.23), communities with high illiteracy rates (OR 1.13, 95% CI 1.05 to 1.23), and countries with high fertility rates (OR 4.43, 95% CI 1.04 to 18.92) were more likely to be unimmunised. Conclusion: We found that individual and contextual factors were associated with childhood immunisation, suggesting that public health programmes designed to improve coverage of childhood immunisation should address people, and the communities and societies in which they live

Rubella vaccine introduction in the South African public vaccination schedule : mathematical modelling for decision making

CITATION: Motaze, Nkengafac Villyen et al. 2020. Rubella vaccine introduction in the South African public vaccination schedule : mathematical modelling for decision making. Vaccines, 8(3):383, doi:10.3390/vaccines8030383.The original publication is available at: https://www.mdpi.comBackground: age structured mathematical models have been used to evaluate the impact of rubella-containing vaccine (RCV) introduction into existing measles vaccination programs in several countries. South Africa has a well-established measles vaccination program and is considering RCV introduction. This study aimed to provide a comparison of different scenarios and their relative costs within the context of congenital rubella syndrome (CRS) reduction or elimination. Methods: we used a previously published age-structured deterministic discrete time rubella transmission model. We obtained estimates of vaccine costs from the South African medicines price registry and the World Health Organization. We simulated RCV introduction and extracted estimates of rubella incidence, CRS incidence and effective reproductive number over 30 years. Results: compared to scenarios without mass campaigns, scenarios including mass campaigns resulted in more rapid elimination of rubella and congenital rubella syndrome (CRS). Routine vaccination at 12 months of age coupled with vaccination of nine-year-old children was associated with the lowest RCV cost per CRS case averted for a similar percentage CRS reduction. Conclusion: At 80% RCV coverage, all vaccine introduction scenarios would achieve rubella and CRS elimination in South Africa. Any RCV introduction strategy should consider a combination of routine vaccination in the primary immunization series and additional vaccination of older childrenPublisher's versio
