The forecast for DTP3 immunization coverage in the US is consistent at 94% from 2024 to 2028. In 2023, immunization coverage stood at a similar level, indicating no significant year-on-year variation or percentage change over the last two years. Given this stability, the compound annual growth rate (CAGR) over the next five years can be expected to remain flat, implying a consistent immunization effort across the country.

Future trends to watch for include:

Potential policy changes impacting vaccination programs, which could influence coverage rates.
Public health campaigns and their effectiveness in maintaining or improving immunization adherence.
The impact of emerging health threats or outbreaks that may drive changes in immunization priorities.
