From 2024 to 2028, the forecast for Polio Vaccine Third Dose (Pol3) immunization coverage in the US remains constant at 92% for children aged one year old. This consistent value suggests a stagnant trend without any year-on-year variation. As of 2023, actual data also indicated 92% coverage, meaning there is zero growth or decline forecasted over this period, bringing no change to the five-year CAGR as well.

Future trends to watch for include:

Potential changes in public health policies that could impact immunization rates.
Emerging public health awareness and educational campaigns, possibly affecting vaccine uptake.
Influence of anti-vaccine sentiments, which could alter current steady projections.
