Using the COMMVAC taxonomy to map vaccination communication interventions in Mozambique

Improved communication about childhood vaccination is fundamental to increasing vaccine uptake in low-income countries. Mozambique, with 64% of children fully vaccinated, uses a range of communication interventions to promote uptake of childhood immunisation.; Using a taxonomy developed by the 'Communicate to Vaccinate' (COMMVAC) project, the study aims to identify and classify the existing communication interventions for vaccination in Mozambique and to find the gaps.; We used a qualitative research approach to identify the range of communication interventions used in Mozambique. In-depth semi-structured interviews were carried out with key purposively selected personnel at national level and relevant documents were collected and analysed. These data were complemented with observations of communication during routine vaccination and campaigns in Nampula province. We used the COMMVAC taxonomy, which organises vaccination communication intervention according to its intended purpose and the population targeted, to map both routine and campaign interventions.; We identified interventions used in campaign and routine vaccination, or in both, fitting five of the seven taxonomy purposes, with informing or educating community members predominating. We did not identify any interventions that aimed to provide support or facilitate decision-making. There were interventions for all main target groups, although fewer for health providers. Overlap occurred: for example, interventions often targeted both parents and community members.; We consider that the predominant focus on informing and educating community members is appropriate in the Mozambican context, where there is a high level of illiteracy and poor knowledge of the reasons for vaccination. We recommend increasing interventions for health providers, in particular training them in better communication for vaccination. The taxonomy was useful for identifying gaps, but needs to be more user-friendly if it is to be employed as a tool by health service managers

Identification of preliminary core outcome domains for communication about childhood vaccination : an online Delphi survey

Communication interventions for childhood vaccination are promising strategies to address vaccine hesitancy, but current research is limited by the outcomes measured. Most studies measure only vaccination-related outcomes, with minimal consideration of vaccine hesitancy-relevant intermediate outcomes. This impedes understanding of which interventions or elements are effective. It is also unknown which outcomes are important to the range of stakeholders affected by vaccine hesitancy. Outcome selection shapes the evidence base, informing future interventions and trials, and should reflect stakeholder priorities. Therefore, our aim was to identify which outcome domains (i.e. broad outcome categories) are most important to different stakeholders, identifying preliminary core outcome domains to inform evaluation of three common vaccination communication types: (i) communication to inform or educate, (ii) remind or recall, and (iii) enhance community ownership.; We conducted a two-stage online Delphi survey, involving four stakeholder groups: parents or community members, healthcare providers, researchers, and government or non-governmental organisation representatives. Participants rated the importance of eight outcome domains for each of the three communication types. They also rated specific outcomes within one domain ("attitudes or beliefs") and provided feedback about the survey.; Collectively, stakeholder groups prioritised outcome domains differently when considering the effects of different communication types. For communication that aims to (i) inform or educate, the most important outcome domain is "knowledge or understanding"; for (ii) reminder communication, "vaccination status and behaviours"; and for (iii) community engagement communication, "community participation". All stakeholder groups rated most outcome domains as very important or critical. The highest rated specific outcome within the "attitudes or beliefs" domain was "trust".; This Delphi survey expands the field of core outcomes research and identifies preliminary core outcome domains for measuring the effects of communication about childhood vaccination. The findings support the argument that vaccination communication is not a single homogenous intervention - it has a range of purposes, and vaccination communication evaluators should select outcomes accordingly

Descriptive and ecological studies and case records made available by the Ministry of Health were used to analyze measles vaccination coverage. Statistical analysis was performed using time series and spatial analysis. Vaccine coverage rates ranged from 82% to 99%. Coverage rates in Maputo city were under 70% and in Niassa province they were over 100%. Coverage showed a clustered pattern in the districts. The measles incidence rate was 1.58 per 100,000 inhabitants (0.00-40.08 per 100,000 inhabitants); districts bordering neighboring countries presented high incidence rates. Although measles morbidity and mortality has decreased in Mozambique, vaccine coverage has been insufficient to interrupt measles transmission. Enhanced surveillance, including investigation of cases and outbreaks, and improvements in measles vaccination are recommended in order to achieve a homogenous coverage rate of ≥ 95% for both routine and mass vaccination campaigns.El objetivo de este artículo fue analizar las acciones de eliminación del sarampión en Mozambique, considerando el impacto del programa de vacunación a lo largo del período de 2000-2011.

Outcomes mapping study for childhood vaccination communication : too few concepts were measured in too many ways

The objectives of this article are to (1) comprehensively catalog outcomes measured in trials of childhood vaccination communication interventions and (2) analyze patterns and trends in outcome selection. To achieve these objectives, we developed a Trial Outcomes Map for vaccination communication.; We searched the Cochrane Central Register of Controlled Trials for trials of childhood vaccination communication interventions, extracting verbatim all outcome information from included trials. Through thematic grouping, we categorized outcomes based on conceptual similarities, forming a Trial Outcomes Map.; We identified 112 relevant trials containing 209 outcomes. Thematic analysis revealed three overarching Outcome Categories: consumer-, vaccination-, and health system-related outcomes. These categories contain 21 Outcome Types (eg, "knowledge," "cost"), measured using 66 different Outcome Variables. Vaccination outcomes were measured most frequently and health system-related outcomes least frequently. Consumer outcomes are increasingly measured in more recent trials.; The number of measures used for the same outcomes complicates data synthesis and interpretation. Despite recent trends toward including consumer outcomes, intermediate outcome measurement is lacking, hampering understanding of how and why vaccination communication interventions do or do not work. This Map may improve outcome consistency in future trials and will contribute to a forthcoming core outcome set

Leprosy indicators and diagnosis delay in Mogovolas, Meconta and Murrupula district of Nampula Province, Mozambique: A baseline survey

Objectives Leprosy is a chronic infectious disease caused by Mycobacterium leprae. The PEP4LEP project will compare two integrated skin-screening interventions combined with the distribution of a single dose of rifampicin as post exposure prophylaxis (SDR-PEP) for contacts of leprosy patients. To implement the study in Mozambique, it was necessary to assess recent epidemiological indicators of leprosy and to estimate case detection delay as a main outcome indicator at baseline. Methods This was a descriptive study to establish the trend of epidemiological indicators of leprosy in the Nampula province districts Murrupula, Meconta and Mogovolas in Mozambique, between 2015 and 2019; and to calculate the average delay to diagnose leprosy cases in these districts. The National Leprosy Control Programme was also described. For the estimation of the case detection delay, 81 recently diagnosed patients were interviewed. Results There were 939 new leprosy cases detected in the three districts from 2015 to 2019, with a high proportion of disability (17.0%). The mean diagnosis delay was 26.6 months (95% CI: 18.4–34.7), while the median was 17.0 months. Multibacillary cases had an average delay of 27.9 months (95% CI: 18.6–37.1), while those with grade 2 disability had an average delay of 47.8 months (95% CI: 15.4–80.2). Conclusion The long case detection delay and high grade 2 disability rates indicate that there is a need for active case finding and chemoprophylaxis with SDR-PEP to help interrupt the chain of Mycobacterium leprae transmission in Nampula province

Childhood vaccination communication outcomes unpacked and organized in a taxonomy to facilitate core outcome establishment

We present a comprehensive taxonomy of outcomes for childhood vaccination communication interventions. Adding to our earlier map of trial outcomes, we aimed to (1) identify relevant outcomes not measured in trials, (2) identify outcomes from stakeholder focus groups, and (3) organize outcomes into a taxonomy.; We identified additional outcomes from nonvaccination health communication literature and through parent and health care professional focus groups. We organized outcomes into the taxonomy through iterative discussion and informed by organizational principles established by leaders in core outcome research.; The taxonomy includes three overarching core areas, divided into eight domains and then into outcomes. Core area one is psychosocial impact, including the domains "knowledge or understanding," "attitudes or beliefs," and "decision-making." Core area two is health impact, covering "vaccination status and behaviors" and "health status and well-being." Core area three is community, social, or health system impact, containing "intervention design and implementation," "community participation," and "resource use."; To our knowledge, this taxonomy is the first attempt to conceptualize the range of potential outcomes for vaccination communication. It can be used by researchers selecting outcomes for complex communication interventions. We will also present the taxonomy to stakeholders to establish core outcome domains

Stakeholder perceptions of communication about vaccination in two regions of Cameroon: a qualitative case study

Understanding stakeholders' (parents', communities' and health workers') perspectives of communication about childhood vaccination, including their preferences for its format, delivery and content, is an important step towards designing better communication strategies and ensuring more informed parents. Our objectives were to explore stakeholders' views, experiences and preferences for childhood vaccination communication in Cameroon.; In 2014, in the Central and North West Regions of Cameron, we gathered qualitative data for our case study using the following methods: semi structured interviews; observations and informal conversations during routine immunization clinics and three rounds of the National Polio Immunization Campaign; document analysis of reports and mass media communications about vaccination; and a survey of parents. We conducted a thematic analysis of the qualitative data to identify themes relating to views, experiences and perceptions of vaccination information and its delivery. Survey data were analysed using simple descriptive statistics.; All of the parents interviewed felt that vaccinating their child was important, and trusted the information provided by health workers. However, many parents wanted more information. Parents did not always feel that they could ask questions during vaccination appointments. All participants felt that health workers and vaccination clinics were important sources of information. Social mobilisation activities such as door-to-door visits and announcements during religious services were important and accepted ways of communicating information, especially during vaccination campaigns. Information communicated through mass media and text messages was also seen as important. In general, stakeholders believed that more consistent messaging about routine vaccination through community channels would be helpful to remind parents of the importance of routine vaccination during ongoing rounds of vaccination campaigns against polio.; This study confirms that parents regard information about childhood vaccination as important, but that health services need to be organized in ways that prioritize and facilitate communication, particularly about routine vaccination
