Abstract
Background
Infectious diseases are more common and severe in patients with HIV, which show different response to vaccines and a diminished protection. It is therefore very important to assess knowledge and attitudes towards vaccination in people with HIV, since precise vaccination coverage and vaccine hesitancy are not well established in this subgroup of patients.
Methods
A sample of 119 patients with HIV completed a cross-sectional survey. Patients were recruited during their routine medical examination at the infectious diseases clinic in Turin. The survey explored these main areas: demographics and history of HIV infection, vaccination history, attitudes towards vaccination, confidence in the public health system, contagion risk and disease seriousness perception. In this preliminary phase descriptive analysis were conducted.
Results
Preliminary data show that mean age of the participants was 49.51 years, 80% were males. The median of HIV infection duration was 10 years, while the median of the lymphocyte count was 762.50 cells/mm3. The disease with the highest vaccination coverage was tetanus (88.7%), considered a serious or very serious disease by 85.6% of the participants, despite low or very low contagion risk perception (84.1%). The disease with the lowest vaccination coverage was Herpes Zoster (7.3%), despite high or very high seriousness perception (70%). Furthermore, 99.1% of the participants showed high or very high confidence toward public health system professionals, and the majority of them (59.5%) stated that vaccines are more useful for the community than for the single person.
Conclusions
Vaccination coverage is still not fully satisfactory regarding diseases considered infrequent or mild. Considering the high level of confidence toward the public health system that has emerged, it is necessary to implement informative and operative strategies about vaccination for European HIV patients, which are particularly at risk regarding infectious diseases.
Key messages
Vaccination coverage and risk perception in HIV patients is not satisfactory for many diseases and an effort to implement informative strategies in Europe is needed. The role of vaccination in preventing infectious diseases in HIV patients should be recognized and strengthened by relying on the high level of confidence toward European public health systems.
