AI Article Synopsis

  • The article examines vaccination rates for children under one year old in Minas Gerais from 2015 to 2020, focusing on various vaccines including Bacillus Calmette and Guérin and polio.
  • The study uses an ecological, time-series approach, analyzing data from the 28 Regional Health Management units to identify trends in vaccination coverage.
  • A notable decline in vaccination rates was observed in 2020, with eight regions showing decreasing trends for at least five vaccines, particularly the Pentavalent vaccine, which fell in coverage in over 60% of those regions.

Article 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.

Background: In settings with low pneumococcal conjugate vaccine (PCV) coverage, multi-age cohort mass campaigns could increase population immunity, and fractional dosing could increase affordability. We aimed to evaluate the effect of mass campaigns on nasopharyngeal pneumococcal carriage of Pneumosil (PCV10) in children aged 1-9 years in Niger.

Methods: In this three-arm, open-label, cluster-randomised trial, 63 clusters of one to four villages in Niger were randomly assigned (3:3:1) using block randomisation to receive campaigns consisting of a single full dose of a 10-valent PCV (Pneumosil), a single one-fifth dose of Pneumosil, or no campaign.

January 2025

Paediatric Respiratory and Sleep Department, Women's and Children's Hospital, Adelaide, South Australia, Australia.

Background: Children with cystic fibrosis are more likely to become severely unwell with influenza-associated illness compared to children without chronic lung disease. The provision of accessible influenza vaccinations is essential in the prevention of infection.

Objectives: To describe the prevalence of the influenza vaccine uptake in children with cystic fibrosis from 2016 to 2020 at a single tertiary paediatric hospital site and determine if the COVID pandemic of 2020 and the introduction of telehealth encounters affected the vaccine uptake.

Background: Patients with congenital heart defects (CHDs) are at higher risk for infectious diseases. This may partly be due to frequent hospital stays and the associated exposure to pathogens. This study aims to provide a comprehensive overview of immunisation coverage among twins in which at least one twin has CHD.
