[Vaccine coverage survey of the elderly in 11 Italian regions].

In 2002, a sample survey of the population > or =65 years of age was conducted in 11 Italian regions that included information on the influenza, pneumococcal, and tetanus vaccination status. In each region, cluster sampling was used to select 210 individuals. In the Campania region, a separate random sample of 100 individuals was selected for Naples. Information on vaccination status was collected via an interview conducted in the participants' homes. A total of 2299 persons participated in the survey. During the 2001--2002 influenza season, 61% of the population reported that they had been vaccinated (regional range 39%-70%). The proportion of the population that had received an influenza vaccine increased with age and was higher than those with underlying diseases and conditions (70% of those > or =75 years of age with underlying problems). The percentage of those who reported having been vaccinated against tetanus was 54% (regional range 11% to 79%); coverage was higher among males and decreased with age. Only 24% of the sample reported having been adequately vaccinated (at least 3 doses, of which the last was administered during the last 10 years). Five percent had been vaccinated against pneumococcus, and none of the regions had a coverage higher than 15%. The elderly represent a segment of the population that is especially vulnerable to infectious diseases and often have problems with access to health services. These findings underline the need to improve vaccine coverage using strategies specifically targeted for this age group.
