“…Para além da meta de cobertura estipulada, a OMS evidencia também outros indicadores relevantes nesse contexto, como a homogeneização das coberturas vacinas dentro do território 9 . Nos últimos anos, o Brasil 3,10-13 e todo o mundo experenciaram a queda da cobertura vacinal de vários imunobiológicos, queda potencializada pela pandemia causada pelo coronavírus (COVID-19) [14][15][16] .…”

Resumo O objetivo é analisar a classificação de risco de transmissão de doenças imunopreveníveis nos 853 municípios de Minas Gerais (MG) após dois anos de início da pandemia de COVID-19. Estudo epidemiológico com dados secundários da cobertura vacinal e taxa de abandono de dez imunobiológicos recomendados para crianças menores de 2 anos, no ano de 2021, em MG. Em relação à taxa de abandono, este indicador foi avaliado somente para as vacinas multidoses. Após o cálculo de todos os indicadores, os municípios do estado foram classificados de acordo com o risco de transmissão de doenças imunopreveníveis em cinco estratos. Minas Gerais apresentou 80,9% dos municípios classificados como alto risco para transmissão de doenças imunopreveníveis. Em relação à homogeneidade das coberturas vacinais (HCV), os municípios de grande porte apresentaram a maior porcentagem de HCV classificada como muito baixa e 100% desses municípios foram classificados como de alto ou muito alto risco para transmissão de doenças imunopreveníveis, com significância estatística. A utilização de indicadores de imunização por município é efetiva para o delineamento do cenário de cada território e a proposição de políticas públicas em saúde visando o aumento das coberturas vacinais.

“…The number of cases among children younger than 2 years has diminished posterior the introduction of Meningococcal C vaccine in the National Immunization Program in Brazil (Cardoso et al, 2015). However, the vaccination rates for this disease were considerably reduced in all states and in the Federal District of Brazil, during the COVID-19 pandemic (da Silva et al, 2022). Children who were not vaccinated can be infected by Meningococcal disease, suffering harmful consequences, including hearing loss like the patient reported in this study.…”

Globally around 34 million children present disabling hearing loss. If unaddressed, hearing loss can negatively impact several aspects such as communication, cognition, language, and speech. Most needy people with hearing impairment do not have access to treatments and it’s a national and international public health problem. Meningococcal disease is caused by the bacterium Neisseria meningitides, affects mainly children, can cause hearing loss, and is a global public health challenge. This study aimed to present the case report of a child who acquired meningococcal disease and bilateral profound sensorineural hearing loss in primary infancy. At the age of six months, the child acquired meningococcal meningitis and performed antibiotic therapeutics. Four years later, the audiometric evaluation detected hearing loss. At the age of seven years, the patient started speech language therapy sessions. At the age of nine years, hearing prostheses were provided by a hospital. At the age of ten, the child began to deny the use of hearing aids at home and school. Two years later, she started her studies at a special school where the deaf community is clearly present. At the age of fourteen, the patient became completely fluent in Sign language, stopping speech therapy sessions. The analyzed case demonstrated a lack of children’s surveillance by a multidisciplinary team and the relevance of following children’s guidance vaccination. It is required to provide adequate interventions for children with hearing loss, which can potentially aid them to develop their skills and to achieve a better quality of life.

“…In Minas Gerais—the fourth state with the largest territorial area and the second in number of inhabitants, located in the Southeast region of the country 14 — the drop in vaccination coverage and the increase in the number of municipalities at high risk for the transmission of vaccine-preventable diseases followed a similar trend compared to the other Brazilian states 10 from 2015 to 2020. Considering the 28 Regional Health Administrations/Regional Health Superintendencies (RHA/RHS) in the state of Minas Gerais as the unit of analysis, the lowest proportion of RHA/RHS that achieved the recommended vaccination coverage targets for the immunobiologicals studied in 2020 was identified 11 .…”

OBJECTIVE: Analyze the impact of the state research-action project on immunization indicators (vaccination coverage – VC, homogeneity of vaccination coverage – HVC, dropout rate – DR, and risk rating) before and after the intervention in municipalities and priority Regional Health Administrations/Regional Health Superintendencies (RHA/RHS). METHODS: The state research-action project was a before-after community clinical trial conducted in 212 municipalities belonging to eight RHA/RHS in the state of Minas Gerais, Brazil. The study sample comprised RHA/RHS with a decreasing trend for routine vaccination coverage in children under one year from 2015 to 2020. This study used secondary VC and DR data from 10 immunobiologicals recommended for children younger than two years from January to December 2021 (pre-intervention period, prior to the state research-action project) and from January to December 2022 (post-intervention period). The categorical variables were presented in proportions, and initially, a comparison was made between those of DR, HVC, and the risk rating for the transmission of vaccine-preventable diseases, according to the two periods (2021 and 2022), using the McNemar test. RESULTS: All immunization indicators increased after conducting the research-action project. In 2021, 80.66% of the state’s municipalities had a risk rating for the transmission of vaccinepreventable diseases as “high and very high.” In 2022, the value reduced to 68.40%. CONCLUSIONS: Risk rating for the transmission of vaccine-preventable diseases is an important mechanism to assist managers in defining priorities. The state research-action project used a method that enabled the construction and execution of unique action plans for each municipality, directing the improvement of immunization indicators in the state.
