The Trajectory of Brazilian Immunization Program between 1980 and 2018: From the Virtuous Cycle to the Vaccine Coverage Decline.

BACKGROUND: Public health policies are crossed by economic and political interests that can affect the maintenance of the immunization programs and their vaccination coverages. The aim was to investigate the political and economic conditions that marked the trajectory of the Brazilian immunization program from 1980 to 2018. METHODS: Documentary research gathered data on public expenditures with epidemiological surveillance and vaccine procurement and nationwide estimates of vaccine coverage. The scientific literature on the program's implementation and the country's political and economic conditions was examined. The theoretical approach was based on historical institutionalism. RESULTS: The results showed rising, high rates maintaining and falling vaccination coverages in the period. As of 2010, there was a tendency for a reduction in total federal spending on epidemiological surveillance, putting pressure on the budgets of the sub-national governments in their respective areas of coverage, and on federal spending in dollars for the acquisition of immunobiologicals and inputs. CONCLUSIONS: The amplitude and complexity of the program's trajectory have been crossed by diverse dynamics conditioned by economic and political interests reflecting at a deeper level the advance of capitalism through fiscal austerity measures over democracy's aspirations for greater balance and justice in the distribution of resources.

Cost-effectiveness analysis measuring the total costs against the health benefits of three different rotavirus vaccines for Mexico.

Rotavirus (RV) infection causes acute rotavirus gastroenteritis (RVGE) in infants. Safe and effective RV vaccines are available, of which Mexico has included one in its national immunization program (NIP) since 2007. Health outcome gains, expressed in quality-adjusted life years (QALYs), and cost improvements are important additional factors for the selection of a NIP vaccine. These two factors were analyzed here for Mexico over one year implementing three RV vaccines: 2-dose Rotarix (HRV), versus 3-dose RotaTeq (HBRV), and 3-dose Rotasiil (BRV-PV), presented in a 1-dose or 2-dose vial). HRV would annually result in discounted QALY gains of 263 extra years compared with the other vaccines by averting an extra 24,022 homecare cases, 10,779 medical visits, 392 hospitalizations, and 12 deaths. From a payer's perspective and compared with HRV, BRV-PV 2-dose vial and BRV-PV 1-dose vial would annually result in $13,548,179 and $4,633,957 net savings, respectively, while HBRV would result in $3,403,309 extra costs. The societal perspective may also show savings compared with HRV for BRV-PV 2-dose vial of $4,875,860, while BRV-PV 1-dose vial and HBRV may show extra costs of $4,038,363 and $12,075,629 respectively. HRV and HBRV were both approved in Mexico, with HRV requiring less investment than HBRV with higher QALY gains and cost savings. The HRV vaccine produced those higher health gains due to its earlier protection and greater coverage achieved after its schedule completion with two doses only, providing full protection at four months of age instead of longer periods for the other vaccines.

Rotavirus (RV) infection causes acute diarrhea in infants and can be life-threatening. Several safe and effective vaccines against RV and its complications exist. For many governments choosing vaccines for national immunization programs, total costs or savings and health gains are important factors in the selection process. We compared the costs and health benefits of three RV vaccines for Mexico: HRV, HBRV, and BRV-PV, that have different dosing schedules: two doses for HRV and three doses for HBRV and BRV-PV. HRV is currently part of the national immunization program in Mexico. HRV would result in more health benefits as it incurs fewer RV-related cases, medical visits, hospitalizations, and infant deaths than the other vaccines due to its early protection achieved after only two doses to complete its schedule. However, from a payer's perspective, the least expensive vaccine was BRV-PV, while HRV was less expensive than HBRV. From a societal perspective, also accounting for families' costs and loss in income due to an infant's RV disease, and the families' costs and loss in income when accompanying the infant to the vaccination center, the HRV vaccine was less expensive than HBRV and BRV-PV presented in a 1-dose vial, while more expensive than BRV-PV presented in a 2-dose vial. HRV and HBRV are both approved in Mexico, although HBRV requires a greater investment at lower health benefits than HRV, from both a payer's and a societal perspective. A 2-dose vaccination scheme is an important asset for the economic value of this vaccination program.

Indicadores do Programa Nacional de Imunizações em menores de um ano: tendência temporal no Maranhão, Brasil, 2010 a 2021 / Indicators of the National Immunization Program for children under one year old: time trend in Maranhão, Brazil, 2010 to 2021

Resumo Objetivou-se analisar a tendência dos indicadores do Programa Nacional de Imunizações (PNI) em menores de um ano e classificar os municípios quanto ao risco de transmissão de doenças imunopreveníveis (RTDIp) no Maranhão de 2010 a 2021. Estudo ecológico de série temporal, baseado em dados secundários de cobertura vacinal (CV), homogeneidade de cobertura vacinal (HCV), proporção de abandono (PA) e RTDIp, com abrangência estadual, para vacinas do calendário nacional infantil. Regressão de Prais-Winstein estimou tendência (α = 5%) e variação percentual anual (VPA) dos indicadores. Houve CV flutuantes e discrepantes entre as vacinas, com tendência decrescente (p < 0,01), exceto contra hepatite B (p = 0,709) e rotavírus (p = 0,143). As quedas mais acentuadas foram para as vacinas contra febre amarela e BCG. Todas as taxas de HCV estavam abaixo do esperado, com a diminuição a partir de 2014 e VPA de 5,75% a 14,02%. Houve tendência crescente da PA para pentavalente e poliomielite. No período de 2015 e 2021 houve incremento de 52,54% na proporção dos municípios maranhenses com RTDIp muito alto (p = 0,025) e alto (p = 0,028). Ao longo de 12 anos, houve piora dos indicadores do PNI em menores de um ano, reafirmando a suscetibilidade para o surgimento de doenças imunopreveníveis.

Abstract We aimed to analyze the trend of indicators of the National Immunization Program (acronym in Portuguese. PNI) in children under one-year-old and classify municipalities regarding the risk of transmission of vaccine-preventable diseases (RTVPD) in Maranhão from 2010 to 2021. This ecological time series study was based on secondary data on vaccination coverage (VC). vaccination coverage homogeneity (VCH). proportion of abandonment (PA). and RTVPD. with state coverage for vaccines in the national children's calendar. Prais-Winsten regression estimated trends (α=5%) and the indicators' annual percentage change (APC). We identified fluctuating and discrepant VC between vaccines. with a decreasing trend (p < 0.01). except those against Hepatitis B (p = 0.709) and oral human rotavirus (p = 0.143). The sharpest falls were for Yellow Fever (APC = 12.24%) and BCG (APC = 12.25%) vaccines. All VCH rates were lower than expected. with a drop from 2014 and APC between 5.75% (Pneumococcal 10; p = 0.033) and 14.02% (Poliomyelitis; p < 0.01). We observed an increasing trend in PA for Pentavalent (APC = 4.91%; p < 0.01) and Poliomyelitis (APC = 3.55%; p < 0.01). We identified an increase of 52.54% in the proportion of municipalities in Maranhão from 2015 to 2021. with extremely high (p = 0.025) and high (p = 0.028) RTVPD. The PNI indicators deteriorated. reaffirming the susceptibility to the emergence of vaccine-preventable diseases.

Resumo O objetivo deste artigo é analisar as taxas de coberturas vacinais em crianças menores de um ano durante o período de 2015 a 2020 no estado de Minas Gerais (MG). Estudo ecológico, de série temporal, sobre as coberturas vacinais em crianças menores de 1 ano, considerando-se como unidade de análise as 28 Gerências/Superintendências Regionais de Saúde (GRS/SRS) de MG. Analisaram-se as coberturas vacinais dos seguintes imunobiológicos vacinas: contra o Bacilo de Calmette e Guérin (BCG), contra rotavírus humano, contra pneumococo 10, pentavalente, contra meningococo C, contra febre amarela e contra a poliomielite. Empregou-se o modelo autorregressivo de Prais-Winsten para análise de tendência. Destaca-se o ano de 2020, que apresentou a menor proporção de GRS e SRS que alcançaram as metas preconizadas de cobertura vacinal para os imunobiológicos analisados. Quanto à análise de tendência da cobertura, 8 das 28 GRS/SRS apresentaram tendência decrescente de, pelo menos, 5 dos 7 imunobiológicos avaliados. Observou-se tendência decrescente na cobertura vacinal de pelo menos cinco imunobiológicos em oito das GRS /SRS, com destaque para a vacina Pentavalente, que apresentou tendência decrescente de cobertura vacinal em 60,71% das GRS e SRS.

Abstract The scope of this article is to analyze vaccination coverage rates in children under one year of age during the period from 2015 to 2020 in the state of Minas Gerais (MG). It involved an ecological, time-series study on vaccination coverage in children under 1 year of age, considering the 28 Regional Health Management/Superintendencies (GRS/SRS) of MG as the unit of analysis. The following immunobiological vaccine coverage was analyzed: Bacillus Calmette and Guérin, human rotavirus, pneumococcal 10, pentavalent, meningococcus C, yellow fever, and polio vaccines. The Prais-Winsten autoregressive model was employed for trend analysis. The year 2020 stands out, as it presented the lowest proportion of GRS and SRS that reached the recommended vaccine coverage goals for the immunobiologicals analyzed. Regarding the analysis of the coverage trend, 8 of the 28 GRS/SRS showed a decreasing trend for at least 5 of the 7 immunobiologicals evaluated. We observed a downward trend in the vaccination coverage of at least five immunobiologicals in eight of the GRS/SRS, with emphasis on the Pentavalent vaccine, which showed a downward trend in vaccination coverage in 60.71% of the GRS and SRS.

Telemedicine in the National Immunization Program (Brazil): A promising tool.

The coronavirus disease 2019 pandemic abruptly changed the dynamics of basic health care, with the consequent need for adjustments in essential services. The objective of this study was to evaluate the acceptance and impact of telemedicine at a Reference Center for Special Immunobiologicals (CRIE). Methods: Patients aged 18 years or older who had a medical referral to CRIE and agreed to have a telemedicine consultation were included. After the medical appointments, participants answered a satisfaction survey. Results: From April 2021 to February 2022, 702 telemedicine consultation were conducted. Over 3,380 vaccines were prescribed via telemedicine. Of all the participants who answered the satisfaction questionnaire, 99.8% stated that they would recommend the service to other people. Conclusions: Telemedicine proved to be promising tool for healthcare at CRIE and had good acceptance by users, potentially improving access and extending the reach of the National Immunization Program.

The Impact of an Inactivated Hepatitis A Vaccine with One Dose in Brazil: A Retrospective Time-Series.

BACKGROUND: In 2014, a recommended one-dose of inactivated hepatitis A vaccine was included in the Brazilian National Immunization Program targeting children 12-24 months. This decision addressed the low to intermediate endemicity status of hepatitis A across Brazil and the high rate of infection in children and adolescents between 5 and 19 years old. The aim of the study was to conduct a time-series analysis on hepatitis A incidence across age groups and to assess the hepatitis A distribution throughout Brazilian geographic regions. METHODS: An interrupted time-series analysis was performed to assess hepatitis A incidence rates before (2010-2013) and after (2015-2018) hepatitis A vaccine program implementation. The time-series analysis was stratified by age groups while a secondary analysis examined geographic distribution of hepatitis A cases. RESULTS: Overall incidence of hepatitis A decreased from 3.19/100.000 in the pre-vaccine period to 0.87/100.000 (p = 0.022) post-vaccine introduction. Incidence rate reduction was higher among children aged 1-4 years old, with an annual reduction of 67.6% in the post-vaccination period against a 7.7% annual reduction in the pre-vaccination period (p < 0.001). Between 2015 and 2018, the vaccination program prevented 14,468 hepatitis A cases. CONCLUSION: Our study highlighted the positive impact of a recommended one-dose inactivated hepatitis A vaccine for 1-4-years-old in controlling hepatitis A at national level.

Cost-effectiveness analysis of replacing the 10-valent pneumococcal conjugate vaccine (PCV10) with the 13-valent pneumococcal conjugate vaccine (PCV13) in Brazil infants.

Brazil currently has a 10-valent pneumococcal conjugate vaccine (PCV10) pediatric national immunization program (NIP). However, in recent years, there has been significant progressive increases in pneumococcal disease attributed to serotypes 3, 6A, and 19A, which are covered by the 13-valent PCV (PCV13). We sought to evaluate the cost-effectiveness and budget impact of switching from PCV10 to PCV13 for Brazilian infants from a payer perspective. A decision-analytic model was adapted to evaluate the clinical and economic outcomes of continuing PCV10 or switching to PCV13. The analysis estimated future costs ($BRL), quality-adjusted life-years (QALYs), and health outcomes for PCV10 and PCV13 over 5 y. Input parameters were from published sources. Future serotype dynamics were predicted using Brazilian and global historical trends. Over 5 y, PCV13 could prevent 12,342 bacteremia, 15,330 meningitis, 170,191 hospitalized pneumonia, and 25,872 otitis media cases, avert 13,709 pneumococcal disease deaths, gain 20,317 QALYs, and save 172 million direct costs compared with PCV10. The use of PCV13 in the Brazilian NIP could reduce pneumococcal disease, improve population health, and save substantial health-care costs. Results are reliable even when considering uncertainty for possible serotype dynamics with different underlying assumptions.

Conclusión: Se ha desarrollado un instrumento simple capaz de funcionar incluso en lugares sin internet, que aún debe implementarse en una unidad de salud para que se pruebe su efectividad.

Rechazo de los padres a la vacunación obligatoria en Chile. Desafíos éticos y jurídicos / Parental refusal to mandatory vaccination in Chile. Ethical and legal challenges

Resumen: Este artículo se presenta como una reflexión ética y jurídica acerca de la tendencia actual de los pa dres a rechazar la vacunación de sus hijos en un régimen jurídico que establece la obligatoriedad de determinadas vacunas. Se analizan los principales argumentos que los padres usan para rechazar las vacunaciones obligatorias, y, en concreto: el temor a los efectos negativos que la vacunación pueda provocar en el menor; la violación del "derecho a la autonomía"; las creencias religiosas o pseudo- filosóficas; la resistencia a la intervención del Estado en asuntos personales o familiares. De esto, nace un necesario análisis ético sobre la vacunación infantil. Finalmente, se discute la responsabilidad de los padres y del Estado (autoridad sanitaria) en el cuidado de los menores de edad. La vacunación es un beneficio tanto para el inoculado como para la comunidad, la mejor política preventiva. Al mismo tiempo, se configura como un caso complejo que demanda un debate profundo, cuyo fin debe ser el tránsito desde un aparente conflicto entre los padres y el Estado, a una convergencia por el cuidado de los menores de edad. En otros términos, se recalca el hecho de que los padres, más allá del cum plimiento de un deber normativo heterogéneo, deben actuar motivados por la adhesión voluntaria al bien del hijo y de la comunidad.

Abstract: This article is an ethical and legal reflection about the current trend of parents to refuse vaccination of their children under a legal regime that establishes mandatory use of certain vaccines. We analyze the main arguments used by parents to refuse obligatory vaccination, i.e., the fear of the negative effects that vaccination may have on the child; the violation of the "right to autonomy"; religious or pseudo-philosophical beliefs; and the resistance to the State intervention in personal or family mat ters. Therefore, this statement implies a necessary ethical analysis of childhood vaccination. Finally, it will be discussed the responsibility of parents and the State -the health authority- in the care of mi nors. Vaccination is a benefit for both the inoculated and the community, the best preventive policy. At the same time, it is considered a complex case that demands a profound debate, whose purpose should be the transition from an apparent conflict between parents and the State, to convergence for the care of minors. In other words, it is emphasized the fact that parents, beyond the fulfillment of a heterogeneous normative duty, must act motivated by voluntary adherence to the best interest of the child and the community.

Factors influencing HPV vaccine delivery by healthcare professionals at public health posts in São Paulo, Brazil.

OBJECTIVE: To assess the association between Brazilian healthcare providers' characteristics and their knowledge, perceptions, and practices regarding the HPV vaccine. METHODS: An observational cross-sectional study was conducted at five public health posts in São Paulo between July 28 and August 8, 2014. Healthcare professionals directly involved in patient care were asked to complete a written survey. Factors associated with routine verification of HPV vaccination status were evaluated using Poisson regression. RESULTS: Among 200 participants included, 74 (38.5%) reported never and 70 (36.5%) reported always asking about HPV immunization status. Doctors were significantly less likely to report always asking than were community health agents (5/39 [12.8%] vs 32/60 [53.3%]; adjusted prevalence ratio [aPR] 0.25 [95% confidence interval (CI) 0.07-0.91]). Knowledge about the correct dosing schedule was associated with always rather than never verifying vaccination status (aPR 2.46 [95% CI 1.06-5.70]). CONCLUSION: Knowledge and attitude played secondary roles in influencing HPV vaccine verification. Community health agents were crucial for vaccine promotion; continued education and support of this group is essential for the sustained success of HPV immunization efforts in Brazil.

Proposta de gestão on-line das informações de vigilância epidemiológica de eventos adversos pós-vacinação / Proposal for managing online information for epidemiological surveillance of adverse events following immunization

Hoje em dia, uma série de vacinas são capazes de proteger as pessoas, reduzindo drasticamente a incidência de doenças. Para gerenciar as ações de imunização em saúde pública, o Programa Nacional de Imunizações foi criado em 1973. Através dos seus mecanismos de trabalho, tais como, fornecimento de vacinas para toda a população, financiada pelo Governo Federal, sem custos diretos para os vacinados; armazenamento, transporte e suprimento de vacinas em redes de frio adequadas; sistemas de informações confiáveis, o Programa Nacional de Imunizações tem êxito em seus objetivos por controlar várias doenças evitáveis pela imunização. No entanto, sabemos que a ocorrência de eventos adversos pode surgir após a administração desses produtos imunizantes – EAPV. Para monitorar e controlar EAPV, a Vigilância Epidemiológica de Eventos Adversos Pós-Vacinação foi criado pelo Programa Nacional de Imunização, em 1992. Este serviço foi estruturado para reconhecer e identificar os casos de EAPV, subsidiar pesquisas, e assessorar os profissionais de saúde na vigilância de casos, entre outros objetivos que contribuem para o controle de vacinas, saúde e bem-estar da população. Para fazer o controle de eventos adversos, a Vigilância Epidemiológica de EAPV usa um formulário de notificação, manual de monitoramento com informações e instruções para notificar e investigar casos de EAPV e fornecer dados para o sistema de informação. Este último é fundamental para acompanhar os casos suspeitos e confirmados de EAPV, identificando os casos graves, os surtos e controlar os lotes de vacinas que podem causar eventos adversos à população vacinada. Desde 1998, o Programa Nacional de Imunizações tem administrado o Sistema de Informações de Eventos Adversos Pós-Vacinação, desenvolvido pela equipe técnica do Departamento de Informática do Ministério da Saúde – DATASUS. Com base nas diretrizes e critérios para avaliação de sistemas de vigilância,,,

Nowadays, a number of vaccines are able to protect people, reducing dramatically the incidence of diseases. To manage the immunizing actions in public health, the Brazilian National Immunization Program was created in 1973. Through its working mechanisms, such as, providing vaccines for the whole population, funded the FederalGovernment, without direct cost for vaccinees; storage, transportation and supply of vaccines in appropriate cold chain settings; reliable information systems, the National Immunization Program has succeed in its goal to control many diseases preventable byimmunization. However, we know that the occurrence of adverse events may follow the administration of immunizing products – AEFI. To monitor and control AEFI, the Epidemiological Surveillance of Adverse Events Following Immunization was created by National Immunization Program in 1992. This service was structured to recognizeand identify AEFI cases, subsidize research work, and support health professionals in surveillance, and other objectives that contribute to vaccines control, health and welfare of the population. To control adverse events, AEFI’s Epidemiological Surveillance use a notification form, monitoring manual with information and instructions to report and investigate AEFI’s cases and supply data to the information system. The latter is critical to follow up suspected and confirmed cases of AEFI,identifying severe cases, outbreaks and monitor vaccine lots that may cause adverse events to the vaccinated population. Since 1998, the National Immunization Program has managed the Adverse Events Following Immunization’s Informations System,developed by the technical staff in the Ministry of Health Department - DATASUS. Based on the guidelines and criteria for evaluation...
