We examined how risks of hospitalisation for a wide range of vaccine-preventable conditions varied by age and sex among mental health (MH) service users.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291723000776_sec_a2\" sec-type=\"methods\"><jats:title>Methods<\/jats:title><jats:p>Linked population data from New South Wales (NSW), Australia were used to identify vaccine-preventable hospitalisations (VPH) for 19 conditions from 2015 to 2020. Adult MH service users (<jats:italic>n<\/jats:italic> = 418 915) were compared to other NSW residents using incidence rates standardised for age, sex and socioeconomic status. Secondary analyses examined admissions for COVID-19 to September 2021.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291723000776_sec_a3\" sec-type=\"results\"><jats:title>Results<\/jats:title><jats:p>We identified 94 180 VPH of which 41% were influenza, 33% hepatitis B and 10% herpes zoster. MH service users had more VPH admissions [adjusted incidence rate ratio (aIRR) 3.2, 95% CI 3.1\u20133.3]. Relative risks were highest for hepatitis (aIRR 4.4, 95% CI 4.3\u20134.6), but elevated for all conditions including COVID-19 (aIRR 2.0, 95% CI 1.9\u20132.2). MH service users had a mean age of 9 years younger than other NSW residents at first VPH admission, with the largest age gap for vaccine-preventable pneumonias (11\u201313 years younger). The highest relative risk of VPH was among MH service users aged 45\u201365.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291723000776_sec_a4\" sec-type=\"conclusions\"><jats:title>Conclusions<\/jats:title><jats:p>MH service users have increased risk of hospitalisation for many vaccine-preventable conditions. This may be due to reduced vaccination rates, more severe illness requiring hospitalisation, greater exposure to infectious conditions or other factors.
