<scp>COVID</scp>‐19 vaccination coverage and vaccine hesitancy among people with opioid use disorder in Barcelona, Spain

Abstract

More than two-thirds of our sample of people with OUD were fully vaccinated. Complacency and convenience represented a significant barrier to complete vaccination among people with OUD on opioid agonist therapy referred to vaccination clinic sites. Additional measures are necessary to increase vaccination, especially for younger individuals and those with less medical comorbidity. Integrating vaccination services in drug outpatient centres could be a useful alternative.
