Multivariate logistic regression model predicting odds of high SIIV intent

Variable	OR of high SIIV intent (95% CI)	P values
Age >65	0.02 (0.01 to 0.57)	0.02*
No SIIV before HSCT	0.04 (0.02 to 0.56)	0.02*
Benefits of vaccination	2.96 (1.29 to 6.81)	0.01*
Susceptibility to seasonal influenza	0.96 (0.33 to 2.78)	0.64
Likelihood of catching seasonal influenza	1.68 (0.86 to 3.26)	0.13
Severity of seasonal influenza infection	0.69 (0.39 to 1.21)	0.20
Barriers to vaccination	0.69 (0.57 to 0.99)	0.05
Worry less about catching seasonal influenza if vaccinated	4.99 (1.01 to 24.77)	0.05

Overall model was statistically significant compared with a constant only model (p<0.001).

*Statistically significant independent predictor (p<0.05).

HSCT, haematopoietic stem cell transplant; SIIV, seasonal inactivated influenza vaccine.
