Comparison of knowledge and risk perception scores and sub-scores of MHLC are summarized in Table 2 . There were significant differences in knowledge scores and risk perception between the vaccinated and unvaccinated nurses and between those with vaccination intent, no intent or unsure. There was no significant difference in the sub-scores of MHLC between the vaccinated and unvaccinated (data not shown in table) but there was a significant difference for the sub-score of powerful others between those groups with different vaccination intent.
