India's Hepatitis B immunization rates have shown significant volatility between 2013 and 2023. Starting at 70 units in 2013, immunization rates saw strong double-digit increases up to 2015. The trend began stabilizing with smaller increases up to 2017, hitting a peak in 2018 with 99 units. However, there was a marked decline through 2019 and 2020 before a partial recovery starting in 2021, reaching 93.8 units in 2023. The Compound Annual Growth Rate (CAGR) over the last five years stood at approximately -1.07%.

Looking ahead, the forecasted data for 2024 to 2028 suggests a gradual increase from 94.6 to 97.6 units. The projected 5-year CAGR is 0.63%, implying modest but steady growth. This suggests an upward correction and stabilization period following the erratic past decade.

Future Trends to Watch For:

Improvements in vaccine distribution infrastructure which could lead to higher immunization rates.
Government policy changes or new health programs aimed at boosting immunization.
Public perception and awareness campaigns on the importance of Hepatitis B vaccination.
Global health trends and unexpected events like pandemics which may impact immunization efforts.
