No statisti- cally significant differences were observed in intention to be vaccinated between paediatricians practicing in different Canadian regions, neither before (p = 0.4315) nor after (p = 0.4291) the beginning of the campaign. Before the beginning of the vaccination campaign, 13% of paediatricians were undecided about being vaccinated themselves compared to 3% after. Finally, the proportion of paediatricians who reported they had received suffi- cient information on A(H1N1) vaccine increased from 31% before the beginning of the campaign to 73% after (p < 0.001), with 3% of respondents reporting they felt their knowledge was insufficient after the beginning of the vaccination campaign versus 17% before (Table 2). Factors associated with the intention to recommend A (H1N1) pandemic vaccine before and after the start of the vaccination campaign The intention to get vaccinated against A(H1N1) pan- demic influenza themselves (OR = 8.65) and belief that Page 4 of 9 P-value 0.2327 0.4371 ’>21 hrs’ vs. others: 0.1571 None vs. others: 0.0924 0.6915 0.2067 0.0028 A(H1N1) pandemic vaccine would be well accepted by vaccine providers (OR = 6.65) were the most significant factors associated with the intention to recommend A (H1N1) pandemic vaccine to patients. Six other vari- ables were also significantly associated with the inten- tion to recommend the vaccine: belief that seasonal influenza vaccines are very useful to protect child health; perceived economic burden of A(H1N1) influenza ill- ness; self-estimated sufficiency of knowledge about the A(H1N1) vaccine; perceived safety of the A(H1N1) vac- cine; perceived severity of A(H1N1) pandemic influenza and belief that special precautions to prevent A(H1N1) pandemic influenza are needed (Table 3). Multiple correspondence analyses (MCA) Results of MCA supported the associations found in the logistic regression models (Figure 1). Overall, first and second principal components summarized 13.6% of the initial variables’ variability.
