In a multivariable logistic model including demographic factors, previous vaccination experiences, and knowledge/experience of TB, we found that the strongest determinant of willingness to vaccinate was age: adolescents were nearly six times more willing to receive a new TB vaccine as adults (adjusted OR: 5.6, 95% CI: 1.9–19.6). Participants who reported previous issues accessing vaccines were more than three times as willing to receive a new TB vaccine than those who did not report previous access issues (adjusted OR: 3.3, 95% CI: 1.3–8.9). Although not significant at p = 0.05, we also found that participants reporting personal experience with TB (a friend or family member with the disease) (adjusted OR: 2.4, 95% CI: 0.8–7.9) and with a higher knowledge of TB (adjusted OR 2.6, 95% CI: 0.9–7.5) were more willing to receive a new TB vaccine. There were no missing responses for the variables used in the model. (Table 2)
