As of 2023, the Measles-Containing-Vaccine Second-Dose (MCV2) immunization coverage in Japan stood at 94%. Forecasts from 2024 to 2028 show a gradual increase in coverage, starting at 95% in 2024 and reaching 97% by 2028. The year-on-year variation is minimal, with a steady annual increase of approximately 1% over this period. The five-year compound annual growth rate (CAGR) from 2024 to 2028 suggests a modest average increase of around 0.8% per year.
Future trends to watch for include the impact of public health policies and education campaigns, which may further increase immunization rates. Additionally, monitoring the effects of any new vaccine developments or changes in societal attitudes toward vaccination will be critical in forecasting long-term trends in vaccine coverage.
