Willingness to receive Herpes Zoster vaccination among adults and older people: A cross sectional study in Italy.

The objective of this study was to explore the Herpes Zoster (HZ) knowledge and the willingness to receive the HZ vaccination in adults and older people in Italy. The study was conducted on a sample of patients aged ≥65 years and over 50 years with chronic conditions who went to the clinics of general practitioners (GPs) in Campania region, Italy. Data was collected with a questionnaire administered through an interview. Multivariate logistic regression analysis was performed. 427 participants (83.2 %) had heard about HZ infection and correctly knew the main symptoms of the HZ disease, and 196 of them (45.9 %) were aware of the main complications of the infection, such as post-Herpetic Neuralgia (NPE) and Herpes Zoster ophthalmicus (HZO). Only 61 participants (11.8 %) had heard of the availability of a vaccination against HZ in Italy and 39 of them (63.9 %) knew that the vaccination is recommended in at-risk patients aged at least 50 years and for adults aged ≥65 years. 137 participants (26.6 %) had a positive attitude toward the willingness to receive the HZ vaccination. Participants aged 50-64 years, those who have more than one chronic disease, those who have received at least one recommended vaccination, those who had a positive attitude on the usefulness of HZ vaccination, and those who feel the need to receive additional information about HZ vaccination were more likely to have a positive attitude toward the willingness to receive the HZ vaccination. It is needed to implement effective strategies to improve HZ vaccination coverage in order to protect especially frail patients from the most serious complications of the disease.
