Discussion

Systematic analysis estimates higher RSV hospitalisation rates in older adults across European countries, suggesting tailored immunisation needs.

RSV hospitalisation rates in older adults were estimated to be 2.2 to 6.4 times higher with adjustments.
Data from 14 studies showed adjusted annual hospitalisation rates ranging from 193 to 414 per 100,000 person-years.
An ensemble model predicted RSV rates in 23 countries, estimating rates between 223 and 317 per 100,000 person-years.
The study highlights the need for adjusting RSV case ascertainment when planning immunisation strategies.

Zhang et al. (2025) studied this question.
