Regional disparities in BCG vaccination coverage and tuberculosis incidence in infants among Brazilian states.

Bacillus Calmette-Guerin (BCG) vaccination and tuberculosis (TB) incidence in children under 1 year of age are critical public health indicators in Brazil. The coronavirus disease 2019 pandemic disrupted vaccination coverage (VC), potentially impacting TB incidence. Understanding regional disparities in VC and TB incidence can inform targeted interventions.

Impact of BCG Vaccination Disruptions During the COVID-19 Pandemic on Tuberculosis Incidence in Infants: A Nationwide Study in Brazil.

Pandemic-related disruptions led to lower Bacille Calmette-Guérin (BCG) vaccine coverage in Brazil. This study highlights a link between reduced vaccinations and increased tuberculosis pulmonary and extrapulmonary cases in infants. Addressing vaccine hesitancy and ensuring healthcare stability is vital for mitigating impacts.

Impact of the COVID-19 pandemic on the vaccination of children 12 months of age and under: an ecological study.

This study aimed to evaluate the impact of the COVID-19 pandemic on the vaccination numbers for immunization geared toward individuals under 12 months of age in Brazil. This study analyzed the numbers of the nationwide vaccination coverage of ten vaccines present in the calendar from the National Immunization Program (NIP) over the past eight years (2013-2020). This is an ecological study, and all data were taken from the NIP.
