RESUMO

How do unpleasant post-vaccination symptoms become recognized as vaccine 'side effects'? In this paper, we argue that it is not necessarily the logical outcome of scientific verification that it is said to be. The paper draws on an ethnographic study carried out in a small town, El Carmen de Bolivar, on Colombia's Caribbean coast from February through May 2019. In 2014, hundreds of girls in the town reported a range of mysterious symptoms following mass vaccination against the Human Papilloma Virus (HPV). Denying the girls' insistence that their symptoms were due to the vaccine, the official diagnosis was Mass Psychogenic Illness. Comparing these events with studies of controversial responses to other vaccines, we suggest that the pathway from post-vaccination symptoms to 'side effects' is cognitively and socially complex. In particular, it is context-dependent. Drawing on research in medical anthropology, sociology and STS, we argue that the official diagnosis was influenced by the subjects' marginal status; by a projection of the region's violent past onto individual inhabitants; by health professionals' commitment to a restricted notion of evidence (devaluing patients' own accounts); and by an institutional inability or unwillingness to stand against 'global consensus', which deems HPV safe.

RESUMO

Inspired by advances in immunology, in the 1970s scientists began to study the possibilities of mobilizing the human immune system against intruders other than pathogenic viruses and bacteria. In 1972 the suggestion was first made that it might be possible to provoke immunity to narcotic dependence. Because molecules of narcotics such as heroin and cocaine are too small to stimulate an immune response, researchers sought ways of coupling them to immunogenic proteins. The substances they developed soon became known as addiction vaccines. However, despite fifty years of research, and despite the growing problem of addiction, no vaccine against heroin, cocaine, methamphetamine or nicotine addiction has yet been licensed for clinical use. This paper reviews the history of addiction vaccinology, seeks to explain the unique appeal of a vaccinological approach to addiction, and argues for broad discussion of how such vaccines should ultimately be used.

RESUMO

We assessed the development, nutritional status, and complementary feeding of 12- to 23-month-old children from Cuenca, Ecuador in 2013. Ecuador, an upper-middle-income country, developed a child policy in accordance with World Health Organization (WHO) guidelines. We collected cross-sectional survey data. Child development was assessed using the Integrated Management of Childhood Illness Guide-2011. The nutritional status was defined with WHO Child Growth Standards-2006. We investigated nutrient density, WHO Infant and Young Child Feeding Indicators, and nutrient supplementation intake of the complementary feeding. In all, 11.7% of children had "possible developmental delay," stunting was identified in 29.4% of the children, and 25.3% faced overnutrition (overweight risk/overweight/obesity). The complementary feeding composition can be summarized as having adequate fat, high energy (MJ/day) and protein, and low iron and zinc. Children with "possible developmental delay" received less iron (P < .05) than children with normal development. Overall, 30.4% of children had minimum dietary diversity. A total of 47.7% of children received nutrient supplementation. This epidemiological profile of infants remains a challenge for Ecuador's health programs.

RESUMO

Most studies of parenting children with Down syndrome (DS) have been conducted in industrialized countries. They suggest that sensitive communication on the part of professionals, and social support, can lead to acceptance and positive adjustments in the family. This study examined the impact of a diagnosis of DS on Ecuadorian families, in particular at how the diagnosis had been communicated and received, as well as the feelings and experiences which followed. Despite considerable progress in recent years, Ecuador is still marked by discriminatory attitudes which affect children with disabilities and their families, and by the persistence of widespread poverty. This qualitative study, conducted in Cuenca, Ecuador's third largest city, is based on a focus group discussion and four in-depth interviews with Ecuadorian parents of DS children attending a specialist center in the city. The study shows that, reflecting the effects of status differences and lack of appropriate training, professionals rarely communicate a DS diagnosis in an appropriate manner. Further, it is shown that lack of social support, and the widespread stigmatization confronting children with DS and their families, hinder development of positive and empowering adjustments that would best serve the child's and the family's interest.

RESUMO

We analyzed an attempt to develop and clinically test a pneumococcal conjugate vaccine for the developing world, undertaken by public health institutions from the Netherlands, Sweden, Denmark, Norway and Finland: the Dutch Nordic Consortium (DNC), between 1990 and 2000. Our review shows that the premature termination of the project was due less to technological and scientific challenges and more to managerial challenges and institutional policies. Various impeding events, financial and managerial challenges gradually soured the initially enthusiastic collaborative spirit until near the end the consortium struggled to complete the minimum objectives of the project. By the end of 1998, a tetravalent prototype vaccine had been made that proved safe and immunogenic in Phase 1 trials in adults and toddlers in Finland. The planned next step, to test the vaccine in Asia in infants, did not meet approval by the local authorities in Vietnam nor later in the Philippines and the project eventually stopped.The Dutch DNC member, the National Institute of Public Health and the Environment (RIVM) learned important lessons, which subsequently were applied in a following vaccine technology transfer project, resulting in the availability at affordable prices for the developing world of a conjugate vaccine against Haemophilus influenzae type b. We conclude that vaccine development in the public domain with technology transfer as its ultimate aim requires major front-end funding, committed leadership at the highest institutional level sustained for many years and a competent recipient-manufacturer, which needs to be involved at a very early stage of the development.At the national level, RIVM's policy to consolidate its national manufacturing task through securing a key global health position in support of a network of public vaccine manufacturers proved insufficiently supported by the relevant ministries of the Dutch government. Difficulties to keep up with high costs, high-risk innovative vaccine development and production in a public sector setting led to the gradual loss of production tasks and to the 2009 Government decision to privatize the vaccine production tasks of the Institute.

RESUMO

PURPOSE: In El Salvador, children under 12 diagnosed with cancer have access to free treatment at a specialized national facility. Until recently, 13 percent of patients annually abandoned therapy--a serious loss of lives and scarce resources. This qualitative study explores how some parents perceived their child's cancer and treatment, and what led them to stop bringing their child for chemotherapy. METHOD: In in-depth interviews, parents of six children who abandoned their child's cancer treatment discussed sickness and life circumstances during the course of treatment. RESULTS: Poverty, effects of treatment, mistrust, emotions and religious convictions all figured in the parents' explanation of their actions. However, each family weighed these concerns differently. It was the interaction of the concerns, and not the concern per se, that represented the explanatory frameworks the families used to explain stopping their child's treatment. This finding illustrates the parents' navigation among a collection of variable concerns, rather than exposing one fixed cause for their behavior. For example, poverty affects a parent's worldview as well as concrete living conditions, and therefore has a complex relationship with abandonment of treatment. Thus, it follows that strategies to reduce treatment abandonment (and increase a child's chance for survival) must be multidimensional. CONCLUSIONS: Qualitative studies of how families perceive childhood cancer and treatment can illuminate the processes and relationships involved in abandonment of treatment. This approach can also show how families' living circumstances frame their perceptions and inform strategies to improve how medical services are provided, thus reducing abandonment of treatment.

RESUMO

At the beginning of the 1960s, it was clear that a vaccine against measles would soon be available. Although measles was (and remains) a killer disease in the developing world, in the United States and Western Europe this was no longer so. Many parents and many medical practitioners considered measles an inevitable stage of a child's development. Debating the desirability of measles immunization, public health experts reasoned differently. In the United States, introduction of the vaccine fit well with Kennedy's and Johnson's administrations' political commitments. European policymakers proceeded cautiously, concerned about the acceptability of existing vaccination programs. In Sweden and the Netherlands, recent experience in controlling polio led researchers to prefer an inactivated virus vaccine. Although in the early 1970s attempts to develop a sufficiently potent inactivated vaccine were abandoned, we have argued that the debates and initiatives of the time during the vaccine's early history merit reflection in today's era of standardization and global markets.

RESUMO

Based on a case-study of the introduction of measles-mumps-rubella (MMR) vaccine in the Netherlands two decades ago, using documentary and archival sources, this paper examines the way evidence is used in policymaking. Starting from the question of 'what counts as evidence', two central claims are developed. First, the decision to introduce MMR was not one but a series of decisions going back at least seven years, over the course of which the significance attached to various forms of evidence changed. Second, results of international studies were coming gradually to be of greater significance than evidence gathered from within the Netherlands itself. These developments had, and continue to have, major consequences for national scientific competences.

RESUMO

The author argues that a "narrowing down" in the scope of HTA that occurred at the end of the 1970s was paralleled by developments in bioethics at the same time. Both disciplines responded to changes in the institutional and political field in which they operated. Over the past 20 years, decision making in the health field has changed again. To remain relevant, HTA must evolve further. Building in mechanisms for consultation with stakeholders will be an important element in this adjustment.

RESUMO

In the context of global vaccine politics 'vaccine independence' has been defined as the assumption of financial responsibility for vaccine procurement. This paper suggests 'the possibility of vaccine choice' as an alternative meaning for the term. How far does local competence in vaccine development and production provide that possibility? Coupled to the national vaccination programme, such competence enabled the Netherlands to make use of a polio vaccine (Inactivated Polio Vaccine, or IPV) that it was felt best met national needs even though the rest of the world had switched to the alternative attenuated vaccine (generally known as Oral Polio Vaccine, or OPV); by the 1970s IPV was no longer commercially available. Over the past 20 years major changes in vaccine politics have occurred. Does the earlier conclusion regarding local competence still hold? The more recent example of pertussis (or whooping cough) vaccines, where again controversy surrounds the relative merits of alternative vaccines, permits the question to be posed anew. Results of our analysis from the Netherlands suggest, first, that the pressure to conform has become greater, and second, that the taken-for-granted globalism of today's vaccine system is in need of critical examination.

RESUMO

Over the last two or three decades, growing numbers of parents in the industrialized world are choosing not to have their children vaccinated. In trying to explain why this is occurring, public health commentators refer to the activities of an anti-vaccination 'movement'. In the light of three decades of research on (new) social movements, what sense does it make to attribute decline in vaccination rates to the actions of an influential anti-vaccination movement? Two sorts of empirical data, drawn largely from UK and The Netherlands, are reviewed. These relate to the claims, actions and discourse of anti-vaccination groups on the one hand, and to the way parents of young children think about vaccines and vaccination on the other. How much theoretical sense it makes to view anti-vaccination groups as (new) social movement organizations (as distinct from pressure groups or self-help organizations) is as yet unclear. In any event there is no simple and unambiguous demarcation criterion. From a public health perspective, however, to focus attention on organized opponents of vaccination is appealing because it unites health professionals behind a banner of reason. At the same time it diverts attention from a potentially disruptive critique of vaccination practices; the critique in fact articulated by many parents. In the light of current theoretical discussion of 'scientific citizenship' this paper argues that identifying anti-vaccination groups with other social movements may ultimately have the opposite effect to that intended.

RESUMO

The turn of the millennium has been marked by a large-scale mobilisation of resources for immunisation programmes in developing countries. The resources have been generated by public and private sector parties collaborating in the Global Alliance for Vaccines and Immunization (GAVI). GAVI was formed in response to deteriorating immunisation coverage rates occurring in the late 1990s. GAVI is the latest in a line of vaccine initiatives, which have operated over the past 20 years. This article reviews the five most important global immunisation initiatives that have taken place over those past 20 years. It analyses their origins, shifts in global immunisation goals, identifies key actors, assesses the initiatives' capacity to mobilise resources and increase immunisation coverage, and points to possible unintended effects of the initiatives. The study argues that shifts in global immunisation goals lead to fragmentation in the implementation of vaccine programmes at the local level in developing countries. It also suggests that global actors involved in the formulation of these initiatives appear to miss opportunities to build on past experiences and fail to learn from previous mistakes. This raises questions about the initiatives' sustainability and relevance to the overall objective of preventing vaccine-preventable deaths.
