From the available data, BCG immunization coverage in Brazil was 67% in 2024, dropping to 63% in 2025, 58% in 2026, 54% in 2027, and 50% in 2028 for children aged 1 year old. Assuming the coverage in 2023 stood at X%, the forecasted figures highlight a declining trend in BCG vaccine coverage. Year-on-year, the percentage variation indicates a consistent negative trend, with a noticeable annual reduction. The Compound Annual Growth Rate (CAGR) over these five years is -6.08%, indicating a steady yearly decrease in immunization rates.
Future trends to watch for include potential impacts of public health policies on BCG vaccination rates, changes in healthcare infrastructure, and the effects of public awareness campaigns or global health initiatives aimed at increasing vaccination coverage. Monitoring these factors could provide insights into the effectiveness of interventions and help mitigate the declining trend.
