Abstract
OBJECTIVES
Insufficient adult vaccination coverage rates remain an international challenge. This nationwide study aimed at exploring vaccination coverage and predictors of influenza, pneumococcal, herpes zoster, tetanus, measles, and hepatitis B vaccine uptake, following the recommendations of the National Immunization Program for adults.
STUDY DESIGN
This was a multicenter, mixed-methods study conducted at 23 primary care units in six different regions of Greece.
METHODS
A pretested questionnaire was administered to three randomly selected adults who visited each practice daily for 30 consecutive working days.
RESULTS
Among the 1571 participants, vaccination coverage for influenza in the high-risk groups was 55%, 36% for pneumococcal disease, 12% for herpes zoster (HZ), 21% for tetanus, 33% for measles, and 11% for hepatitis B. Perception of low susceptibility to disease due to good health status, concerns about side-effects and vaccines' efficacy, and mistrust in pharmaceutical companies were among common factors associated with the vaccines uptake. The strongest factor associated with the participants' vaccination status was their doctor's recommendation (odds ratio [95% confidence interval] influenza: 6.06 [4.52-8.14], pneumococcal disease: 15.73 [10.98-22.52], HZ: 17.01 [9.05-31.96], tetanus: 23.93 [16.20-35.35], measles: 33.47 [16.85-66.47], and hepatitis B: 73.92 [17.47-312.74]). Being well-informed about each vaccine was also a predictor of its uptake.
CONCLUSIONS
Vaccination coverage was suboptimal and especially low in tetanus, HZ, and hepatitis B immunization. Person-centered approach, with provision of appropriate information about vaccines' safety and efficacy, responding to each patient's needs, as well as physicians' strong recommendation for vaccination are considered crucial to advocate against the spread of vaccine misinformation and increase vaccination coverage.
