Selected manuscripts evaluating psychiatric factors and COVID-19 vaccination.

Reference	Study Design	Assessment	Main Findings
[52]	Cohort study	Structured online surveys	Vaccine hesitancy does not appear to be a major barrier for vaccine uptake amongst patients with mental illness in Denmark.
[53]	Cross sectional	Structured survey	39.5% trusted that COVID-19 vaccine would be safe and effective. Factors independently associated with trust included age (AOR = 1.03, 95 % CI = 1.02, 1.05, p = 0.0001) and wearing a mask all the time (AOR = 2.48, 95 % CI = 1.86, 3.31, p = 0.0001).
[54]		ITQ; GAD-7; PHQ-9; vaccine hesitancy (8 items); 23 items indexing severity of COVID-19 vaccine side effect	Participants with clinical PTSD levels showed more anxiety and depressive symptoms, were vaccinated a few days later, showed higher vaccine hesitancy levels, and displayed more severe side effects.
[55]	Cross sectional study	21-item depression, anxiety and stress scale	A significantly higher proportion of people with depression or anxiety disorder (64.5%) were more willing to pay for the COVID-19 vaccine than healthy controls (38.1%) (p ≤ 0.001)

Note: SMI = serious mental illness; ITQ = the international trauma questionnaire; GAD-7 = general anxiety disorder-7; PHQ-9 = patient health questionnaire-9; PTSD = post-traumatic stress disorder.
