Establishing priorities to strengthen National Immunization Technical Advisory Groups in Latin America and the Caribbean.

Following the COVID-19 pandemic, the Americas faced a significant decline in vaccination coverage as well as increased vaccine hesitancy. The objective of this paper is to summarize the challenges and opportunities outlined by the National Immunization Technical Advisory Groups (NITAGs) in Latin America and the Caribbean (LAC) and prioritize targeted interventions. The exploratory survey included open-ended questions on two primary components: challenges, and opportunities. Free-text comments presented by each NITAG were collated and classified using indicators and sub-indicators of the NITAG Maturity Assessment Tool (NMAT). Opportunities were classified thematically, and priority actions were generated from the responses. All 21 NITAGs in LAC, representing 40 countries, 76 % of which have been active for over a decade, responded to the survey. The most common challenges were establishment and composition (62 %), integration into policymaking (62 %), resources and secretariat (52 %), and stakeholder recognition (48 %). The distribution of responses was seen across the whole sample and did not suggest a more pronounced need in relation to year of establishment. Opportunities included maximizing the Regional NITAG Network of the Americas (RNA) to facilitate collaboration, information sharing, visibility, and communication; existing global, regional, and systemic analyses; the World Health Organization/Pan American Health Organization (WHO/PAHO) templates for standard operating procedures; twinning programs with mature NITAGs; and NITAGs in governance structures. Action plans were outlined to formalize the establishment of NITAGs and broaden their composition; strengthen decision-making and access to data resources; and enhance the credibility of evidence-based recommendations and their uptake by policymakers and the public. NITAG challenges are not unique to LAC. NITAGs have outlined a short-term prioritized action plan which is critical to enhancing NITAG value and importance in countries.

A review of immunization legislation for children in English- and Dutch-speaking Caribbean countries.

Objective: To assess the legislative frameworks concerning childhood vaccination in the English- and Dutch-speaking Caribbean and propose a model legislative framework for Caribbean countries. Methods: This study included a survey of 22 countries and territories in the Caribbean regarding legal vaccination mandates for school entry, budget allocations, sanctions, or exemptions. A legal consultant conducted a comprehensive search and analysis of legislation regarding vaccination among 13 Caribbean countries/territories. A comparative analysis of the legislation under five themes-legislative structure, mandatory vaccination, national immunization schedule, sanctions, and exemptions-formed the basis for the proposed model legislation. Results: Among the 22 Caribbean countries/territories, 17 (77%) had legislation mandating vaccination, 16 (94%) mandated vaccination for school entry, 8 (47%) had a dedicated budget for immunization programs, and 13 (76%) had no legislated national schedules. The source of legislation includes six (35%) using the Education Act, eight (47%) the Public Health Act, and five (29%) a free-standing Vaccination Act. Three countries/territories-Jamaica, Montserrat, and Saint Lucia-had immunization regulations. In 12 (71%) of the 17 countries with legislation, sanctions were included, and 10 (59%) permitted exemptions for medical or religious/philosophical beliefs. Conclusions: Several countries in the Caribbean have made failure to vaccinate a child an offense. By summarizing the existing legislative frameworks and approaches to immunization in the Caribbean, the analysis guides policymakers in making effective changes to immunization legislation in their own countries.

[RESUMEN]. Objetivo. Evaluar los marcos legislativos relativos a la vacunación infantil en el Caribe de habla inglesa y neerlandesa y proponer un modelo de marco legislativo para los países del Caribe. Métodos. En este estudio se incluyó una encuesta en 22 países y territorios del Caribe sobre los requisitos legales de vacunación para el ingreso escolar, asignaciones presupuestarias, sanciones o exenciones. Un consultor jurídico realizó una búsqueda y un análisis exhaustivos de la legislación relativa a la vacunación en 13 países y territorios del Caribe. Un análisis comparativo de la legislación dividido en cinco temas (estructura legislativa, vacunación obligatoria, calendario nacional de vacunación, sanciones y exenciones) formó la base del modelo de legislación propuesto. Resultados. Entre los 22 países y territorios del Caribe, 17 (77%) contaban con leyes sobre vacunación obligatoria, 16 (94%) exigían la vacunación para el ingreso escolar, 8 (47%) tenían un presupuesto dedicado a los programas de vacunación y 13 (76%) no disponían de calendarios nacionales estipulados por ley. Entre las fuentes de la legislación, seis países y territorios (35%) empleaban la ley de educación, ocho (47%) la ley de salud pública y cinco (29%) una ley independiente de vacunación. Tres países y territorios —Jamaica, Montserrat y Santa Lucía— disponían de regulaciones sobre vacunación. Doce (71%) de los 17 países con legislación tenían sanciones y 10 (59%) permitían exenciones por creencias médicas o religiosas o filosóficas. Conclusiones. Varios países del Caribe han tipificado como delito el no vacunar a un niño o niña. Al resumir los enfoques y marcos legislativos existentes para la vacunación en el Caribe, este análisis ofrece orientaciones a los responsables de formular las políticas para que realicen modificaciones efectivas en la legislación relativa a la vacunación en sus propios países.

[RESUMO]. Objetivo. Avaliar as estruturas da legislação relativas à vacinação em crianças no Caribe de língua inglesa e holandesa e propor um modelo de legislação para os países caribenhos. Métodos. Este estudo incluiu uma pesquisa relativa à exigência legal em 22 países e territórios do Caribe de vacinação para admissão em escolas, alocações orçamentárias, sanções ou isenções. Um consultor jurídico realizou ampla pesquisa e análise da legislação relativa à vacinação em 13 países/territórios do Caribe.

Resultados. Entre os 22 países/territórios caribenhos, 17 (77%) tinham legislação que exigia a vacinação; em 16 (94%), a vacinação era obrigatória para admissão na escola; 8 (47%) tinham orçamento exclusivo para programas de imunização; e em 13 (76%), a legislação não contemplava cronogramas nacionais. Com relação à fonte da legislação, seis (35%) países usavam a legislação de educação; oito, (47%) a Legislação de Saúde Pública; e cinco (29%), legislação de vacinação independente. Três países/territórios - Jamaica, Montserrat e Santa Lúcia - tinham regulamentações para imunização. Dos 17 países com legislação, 12 (71%) incluíam sanções e 10 (59%) permitiam isenções por crenças médicas ou religiosas/filosóficas. Conclusões. Diversos países do Caribe estabelecem que não vacinar uma criança é violação da lei. Ao resumir as estruturas de legislação existentes e as abordagens da imunização no Caribe, a análise orienta os formuladores de políticas a realizar mudanças efetivas na legislação de imunização em seus próprios países.

Children and the coronavirus disease 2019 pandemic: a Caribbean perspective.

This study aims to assess coronavirus disease 2019 (COVID-19) surveillance methods, health resources, vaccination coverage and income stratification and quantify burdens of disease and death in children and adolescents in the Caribbean. The investigation was a descriptive, cross-sectional study that included 15 Caribbean countries/territories and utilized surveys and secondary data sources. Quarantine and isolation measures were robust and surveillance strategies were similar. Pediatric specialists were available across the region, but few had designated pediatric hospitals or high-dependency units. There were more cases in children on islands with larger populations. Compared to high-income countries/territories, upper and lower middle-income countries/territories had higher disease burdens, fewer doctors and nurses per 1 000 population, lower bed capacities, and lower vaccination coverage. Child and adolescent cases ranged from 0.60% to 16.9%, compared with a global case rate of 20.2% in 2021. By August 2021 there were 33 deaths among children from Haiti, Jamaica, Trinidad and Tobago, and Barbados. The respective case fatality rates for 0-9-year-olds and 10-19-year-olds were 2.80 and 0.70 in Haiti, 0.10 and 0.20 in Jamaica, and 0.00 and 0.14 in Trinidad, compared with 0.17 and 0.1 globally. Overall COVID-19 incidence and mortality in children were consistent with global estimates. Limited resources have been offset by availability of pediatricians across the region, and minimally direct effects on children. Prioritization of admission of specific at-risk groups, training of first responders and vaccination campaigns targeting pregnant women and vulnerable children and adolescents could benefit countries with low vaccine coverage rates and limited resources.

El presente estudio tiene como objetivo evaluar los métodos de vigilancia, los recursos de salud, y la cobertura de vacunación y la estratificación de los ingresos, así como cuantificar las cargas de enfermedad y muerte de la enfermedad por coronavirus del 2019 (COVID-19) en niños, niñas y adolescentes en el Caribe. La investigación consistió en un estudio descriptivo y transversal que incluyó a 15 países o territorios del Caribe y empleó encuestas y fuentes de datos secundarios. Las medidas de cuarentena y aislamiento fueron sólidas, igual que las estrategias de vigilancia. Había especialistas pediátricos disponibles en toda la región, pero pocos designados en hospitales pediátricos o unidades de alta dependencia. Hubo más casos en pacientes pediátricos en las islas más pobladas. En comparación con los países y territorios de ingresos altos, los de ingresos medianos altos y medianos bajos presentaron una mayor carga de morbilidad, menos personal médico y de enfermería por 1 000 habitantes, menor capacidad de camas y menor cobertura de vacunación. Los casos de niños, niñas y adolescentes oscilaron entre 0,60% y 16,9%, en comparación con una tasa general de casos de 20,2% en el 2021. En agosto del 2021, hubo 33 muertes de pacientes pediátricos de Haití, Jamaica, Trinidad y Tabago y Barbados. Las tasas de mortalidad de los grupos etarios de 0 a 9 años y de 10 a 19 años fueron respectivamente de 2,80 y 0,70 en Haití; 0,10 y 0,20 en Jamaica; y 0,00 y 0,14 en Trinidad; en comparación con 0,17 y 0,1 a nivel mundial. La incidencia general de COVID-19 y la mortalidad en la población infantil fueron coherentes con las estimaciones mundiales. Se compensaron los recursos limitados con la disponibilidad de pediatras en toda la región y efectos directos mínimos en los niños. Priorizar la admisión de grupos específicos de riesgo, la capacitación de los equipos de respuesta inicial y las campañas de vacunación dirigidas a mujeres embarazadas y niños, niñas y adolescentes vulnerables podría beneficiar a los países con recursos limitados y bajas tasas de cobertura de vacunación.

Ocorreram mais casos em crianças nas ilhas com populações maiores. Em comparação com os países/territórios de alta renda, aqueles de renda média-alta e média-baixa apresentaram uma maior carga de morbidade, menos médicos e enfermeiros por 1 000 habitantes, menor capacidade de leitos e menor cobertura vacinal. De 0,60% a 16,9% dos casos ocorreram em crianças e adolescentes, contra uma média mundial de 20,2% em 2021. Até agosto de 2021, haviam ocorrido 33 óbitos de crianças em Barbados, Haiti, Jamaica e Trinidad e Tobago. Os respectivos índices de letalidade nas faixas etárias de 0-9 anos e de 10-19 anos foram 2,80 e 0,70 no Haiti, 0,10 e 0,20 na Jamaica e 0,00 e 0,14 em Trinidad, em comparação com 0,17 e 0,1 no âmbito mundial. Em geral, a incidência e a mortalidade por COVID-19 em crianças foram condizentes com as estimativas mundiais. Os recursos limitados foram compensados pela disponibilidade de pediatras em toda a região e pelos pouquíssimos efeitos diretos sobre as crianças. Priorização de grupos de risco específicos para internação, treinamento de socorristas e campanhas de vacinação dirigidas a gestantes e a crianças e adolescentes vulneráveis poderiam beneficiar países com baixos índices de cobertura vacinal e recursos limitados.

Vertically transmitted chikungunya, Zika and dengue virus infections: The pathogenesis from mother to fetus and the implications of co-infections and vaccine development.

Chikungunya (CHIKV), Zika (ZIKV), and Dengue viruses (DENV) exhibit similar epidemiological and clinical patterns but have different pathophysiological mechanisms of disease manifestations. Differences occur in the severity of clinical presentations with the highest mortality in the general population attributed to DENV and neurological morbidity due to ZIKV. ZIKV and DENV infections can cause fetal loss with ZIKV exhibiting teratogenesis. CHIKV is associated with severe complications in the newborn. Co-circulation of the three viruses and the cross-reactive immune response between ZIKV and DENV viruses has implications for an attenuated clinical response and future vaccine development. Co-infections could increase due to the epidemiologic synergy, but there is limited evidence about the clinical effects, especially for the vulnerable newborn. The purpose of this paper is to review the pathophysiological basis for vertically transmission manifestations due to CHIKV, DENV, and ZIKV, to determine the potential effects of co-circulation on newborn outcomes and the potential for vaccine protection. Inflammatory cytokines are responsible for placental breaches in DENV and ZIKV; Hofbauer cells facilitate the transfer of ZIKV from the placenta to the fetal brain, and high viral loads and mechanical placental disruption facilitate the transmission of CHIKV. Co-infection of these viruses can present with severe manifestations, but the clinical and serologic evidence suggests that one virus predominates which may influence fetal transmission. All three viruses are in different stages of vaccine development with DENV vaccine being fully licensed. Antibody-enhanced infections in seronegative vaccinated candidates who develop natural infection to dengue limit its use and have implications for ZIKV vaccine development. Targeting transmission capacity in the vector could prevent transmission to all three viruses, and breast milk immunity could provide further clues for vaccine development.

The Caribbean Immunization Technical Advisory Group (CITAG); A unique NITAG.

The Global Vaccine Action Plan 2011-2020 called for all countries to establish a National Immunization Technical Advisory Group (NITAG) by 2020. The Caribbean, with its unique geographical context of 22 countries/territories, had limited technical expertise to establish individual NITAGs in small countries. The Caribbean Immunization Technical Advisory Group (CITAG) was launched in 2018. This paper describes the Caribbean context for a common framework for policy and evidence-based decision-making for immunization. Challenges in immunization in the region are reviewed and potential solutions are outlined. A recent decline in immunization rates in the Caribbean, along with outbreaks of vaccine-preventable diseases globally, places the region, a premier tourist destination, in a vulnerable position. The CITAG aims to strengthen the policy and evidence-based decision-making process for immunization to enable the Caribbean to remain at the forefront of vaccine-preventable disease elimination.

The Pathophysiology of Marijuana-induced Encephalopathy and Possible Epilepsy after Ingestion in Children: A Case Series.

Background: Ingestion of marijuana in children presents primarily with encephalopathy and potentially, in severe cases, seizures. There is a growing body of evidence supporting the benefit of medical marijuana as an anticonvulsant treatment for intractable seizures. However, there are limited data regarding its proconvulsant effects after ingestion. In this case series, we review the pathophysiology of marijuana encephalopathy and potential seizures after ingestion of marijuana in infants and young children. Case presentation: We summarized the cases of six children who were admitted to the hospital with neurological symptoms and a positive urine test for tetrahydrocannabinol (THC) between 2016 and 2018. The primary symptom was excessive drowsiness, with two children progressing to an unarousable state. Two cases presented after ingesting a marijuana confectionery, and the caregivers in four cases were unaware that marijuana exposure was responsible for the clinical presentation. All cases resolved without sequelae and were investigated by social services. In one case, a 6-year-old child with developmental delay and a previous episode of seizures presented with recurrent seizures and evidence of marijuana exposure. Marijuana was considered a probable cause due its proconvulsant effects, but a subsequent seizure episode with a negative urine THC ruled this out. Conclusion: Physicians should consider the possibility of ingestion of marijuana in infants and young children who present with symptoms of unexplained drowsiness. Marijuana products have the potential to provoke seizures and affect the developing brain of a child. Self-medication with marijuana products should be dissuaded, particularly in households with young children.

Psychosocial outcomes in a cohort of perinatally HIV-infected adolescents in Western Jamaica.

BACKGROUND: Psychosocial factors interact with adolescent development and affect the ability of HIV-infected adolescents to cope with and adhere to treatment. AIM: To evaluate psychosocial outcomes in perinatally HIV-infected adolescents (PHIVAs) in Western Jamaica after psychosocial intervention. METHODS: The Bright Futures Paediatric Symptom Checklist (BF-PSC) was used for psychological screening of PHIVAs in Western Jamaica. Referred patients were evaluated using the Youth version of the Columbia Impairment Scale (CIS). Demographic, laboratory and clinical data obtained between July 2014 and June 2016 were evaluated retrospectively and outcomes were reviewed before and after psychosocial intervention. RESULTS: Sixty PHIVAs were enrolled and 36 (60%) had a positive BF-PSC score that necessitated referral. The BF-PSC correctly identified 89% of patients with impaired psychosocial assessment by CIS scores. Referred patients were less likely to adhere to treatment, to be virologically suppressed or to have a CD4+ count of >500 cells/µl, and were more likely to be in the late teenage group or to be of orphan status. After intervention, the prevalence of viral suppression increased and median viral load decreased. A difference in mean CD4+ cell count was detected before but not after intervention in teenage and orphan groups. CONCLUSIONS: The BF-PSC identified at-risk PHIVAs with impaired psychosocial functioning. Increased vulnerability was noted in orphans and older teenagers. Psychosocial interventions (including family therapy) reduced psychosocial impairment and improved virological suppression. Mental health intervention should be instituted to facilitate improved clinical outcomes, autonomy of care and transition to adult care.

Chikungunya and Neonatal Immunity: Fatal Vertically Transmitted Chikungunya Infection.

AbstractChikungunya is a mosquito-borne infectious disease that has emerged as a global pathogen. The virus can pass vertically from mother to child especially during the perinatal period, with an intrapartum vertical transmission rate of 50%. Approximately half of the neonates infected with chikungunya present with severe symptoms and infrequently death. This report summarizes two severe cases of vertically transmitted neonatal chikungunya infection. One case was confirmed by real-time reverse transcription polymerase chain reaction and the other fulfilled clinical and epidemiological criteria. Both infants presented on day 3 with abdominal distension, reduced perfusion pressure, and hypotension; acrocyanosis progressing to ischemic digits; and respiratory distress. Both died within 24-48 hours of presentation. The severity of symptoms observed is likely due to a combination of contamination of the fetal blood from highly viremic mothers during delivery and a low innate antiviral type-1 interferon response. Further examination of the neonate's innate immune response to chikungunya may provide clues for the development of potential treatment or vaccine interventions.

Severe eosinophilic meningitis owing to Angiostrongylus cantonensis in young Jamaican children: case report and literature review.

Eosinophilic meningitis caused by Angiostrongylus cantonensis is an endemic and emerging disease that affects adults and children in Jamaica. Most cases resolve without sequelae, but young children are at high risk of neurological damage and death. Treatment with corticosteroids and albendazole is considered safe for adults and children, but protocols for its use in children have not been established. A 19-month-old infant with permanent neurological sequlae caused by Angiostrongylus cantonensis meningitis is reported, and five other Jamaican cases are summarized. A review of the literature of children with permanent neurological sequlae and death is presented. Children <5 years (especially <2) were at increased risk of incomplete recovery and death if they presented with bulbar signs, flaccid paresis and coma. None of the severe or fatal cases received early intervention with anthelminthics, and disease progression was not altered with corticosteroids. In view of the pathophysiology, necropsy reports and animal studies, it seems that the early use of larvicidals may change the course of severe presentations.

Descriptive epidemiology of mortality and morbidity of health-indicator diseases in hospitalized children from western Jamaica.

The objectives of our study were to describe the epidemiology of child-health indicator diseases in western Jamaica, examine differences in indicator diseases between sex and age, and generate hypotheses about causes of disease burden. International Classification of Disease, 10th Revision, coded discharge diagnoses were collected from consecutive admissions for 2003-2005 from a public tertiary care hospital. Mortality data were not coded. Perinatal disease was the most common cause of mortality, with hyaline membrane disease the primary cause. Younger children, particularly males, are disproportionately affected by all indicator diseases (P < 0.001) and more likely to die from acute respiratory tract infections and infectious diseases (P < 0.05). Sickle cell disease was the fourth most common diagnosis. Children in western Jamaica are most affected by diseases of prematurity. These children experience disease burden similar to that of children in other developing countries, but fewer neonatal sepsis and insect-borne infections, and more hematologic illness.
