-19 prisoners were Finland (8.6%) and Ireland (11.8%).13 Regimes for life prisoners differ from one member state to another as do the possibilities for early release. These differences impact the degree of vulnerability of the life prisoners in different member states. The data on other vulnerable groups is less certain. A recent study on the HIV prevalence in prisons estimated that there are approximately 3% of prisoners with HIV.14 This estimate however seems to be based on old data from the time when HIV spread was more difficult to control in general. Other studies indicate that European governments do not collect statistical data on the number of LGBTIQ prisoners and prisoners with disabilities, whereas statistics for prisoners with mental healthcare needs and older prisoners is collected on an unsystematic basis.15 13.
