Psychological, social, and situational factors associated with COVID-19 vaccination intentions: A study of UK key workers and non-key workers

Objectives Vaccine hesitancy is a growing concern and threat to public health. This research will begin to examine the relative influence of relevant psychological, social, and situational factors on intent to engage with a hypothetical COVID-19 vaccine among key workers and non-key workers. Design Cross-sectional. Methods The study utilized a sample of UK adults who completed the 1-month follow-up of The COVID-19 Psychological Wellbeing Study during April/May 2020 and indicated having not been previously diagnosed with COVID-19 (key workers n = 584; not key workers n = 1,021). These groups were compared in relation to their intentions to vaccinate, perceived risk of infection, and symptom severity. Binary logistic regression was used to examine predictors of vaccine hesitancy. Results Overall, 74.2% of the sample (76.2% key workers, 73.1% non-key workers) indicated they would accept a COVID-19 vaccine in future. Key workers (in particular health and social care workers) had a higher perceived risk of becoming infected in the coming months. For key workers, being female and perceiving oneself as having relatively low infection risk in the next 6 months was associated with increased likelihood of vaccine hesitancy. For non-key workers, however, being aged 25-54, having a low or average income and not knowing someone diagnosed with COVID-19 were associated with hesitancy. Conclusions The proportion of individuals willing to accept a vaccine is encouraging but there is much room for improvement. Given the unique predictors of vaccine hesitancy in each group, public health campaigns may benefit from targeted messaging.

Automated summary

The study found that the majority of participants were willing to accept a COVID-19 vaccine, with key workers having a higher perceived risk of infection. The research also highlighted that vaccine hesitancy in different groups was associated with different factors.
