Abstract
ObjectivesVaccination is the most effective way to prevent herpes zoster (HZ) and related complications. This study aimed to investigate the preference of HZ vaccine among older people. Study designA discrete choice experiment was performed. MethodsIn total, 178 adults aged ≥50 years were invited to choose between HZ vaccination scenarios using six vaccine attributes. Two equations were used to calculate participants’ willingness to pay for the vaccine and their predicted choice probability. ResultsThe attributes that significantly influenced participants’ vaccine choices were lower cost, higher effectiveness, reduced side-effects and vaccination of others in their surroundings. ConclusionsImproving medical insurance coverage or reducing the cost of the HZ vaccine will encourage more people to be vaccinated, resulting in reduced burden of disease among older people.
