The acceptance and hesitancy of COVID-19 vaccination among chronic obstructive pulmonary disease (COPD) patients

Abstract

Severe acute respiratory syndrome coronavirus 2, which is responsible for the coronavirus disease 2019 (COVID-19), causes severe clinical outcomes in old individuals and patients with underlying diseases, including chronic obstructive pulmonary disease (COPD). Considering vaccination is still the most effective method to prevent COVID-19-associated death, it is imperative to evaluate COPD patients' attitudes toward the COVID-19 vaccine. This cross-sectional design study was conducted to assess vaccine acceptance and hesitancy among 212 COPD patients who attended the outpatient department from January 1, 2021, to July 31, 2022. All of the patients were not vaccinated and had undertaken lung function test at the time of our survey. Of 212 participants, 164 (77.4%) were willing to be vaccinated immediately while 48 (22.6%) were hesitant to be vaccinated. Compared with the acceptance group, patients who did not accept the vaccination instantly tended to have more comorbidities, like hypertension, coronary heart disease, recent cancers, and higher Modified British Medical Research Council score, or more frequent acute exacerbation. For the patients willing to be vaccinated, the main factors motivating them were an authorities-endorsed vaccine, free vaccination, and no obvious adverse reactions. For the hesitant group, no recommendation from the treating physician was the biggest obstacle for them to accept vaccination. Our results provide useful guidance for making intervention measures to enhance COPD patients' acceptance of a new COVID-19 vaccine. For those patients with comorbidities, treating physicians promoting messages framing the safety of vaccination is necessary to increase immunization rates.
