The forecast for Diphtheria, Tetanus, and Pertussis immunisation in the UK from 2024 to 2028 shows a gradual decline, starting at 91.9% in 2024 and decreasing to 91.4% by 2028. This consistent year-on-year decrease from 2024 onwards indicates a slight reduction in immunisation rates compared to 2023, which stood at 92.0%. The compound annual growth rate (CAGR) reflects a subtle negative trend over these five years.

Future trends to watch for:

The impact of policy changes or public health initiatives that might reverse the declining trend.
Potential external factors such as economic shifts, vaccine supply issues, or changes in public perception impacting immunisation rates.
Technological advancements or innovations in vaccine delivery that could improve immunisation efficiency and coverage.
