From 2013 to 2023, Indonesia's Hepatitis B immunization coverage experienced fluctuations. The coverage peaked at 99 in 2013, followed by a decline in the subsequent years, bottoming out at 80.1 in 2021 during the COVID-19 pandemic. Since then, there has been a slight recovery, with coverage standing at 83.5 in 2023. The average year-on-year variation was notably negative, indicating an overall declining trend during this ten-year period.

Forecasted data from 2024 to 2028 shows minimal growth, with the expected coverage stabilizing around 83.7 by 2028. The forecast five-year CAGR also suggests negligible growth at 0.05%, implying that significant improvements in immunization rates are unlikely without policy changes or interventions. Over the last five years, the CAGR has averaged -2.05%, reflecting a period of recovery yet sluggish growth.

Future trends to watch for:

Potential impacts of new health policies or government initiatives aiming to boost immunization rates
Technological developments and innovations in vaccine delivery systems
Effects of public health campaigns and education on immunization practices
