Objective To evaluate the effects of mother forum on child vaccination rate and its timeliness rate. Methods A total of 596 neonatal mother who were achieved in our hospital from January 2011 to October 2012 were randomly divided into experimental group and control group by the single or plural number of admission sequence on average. Both groups underwent routine education with child vaccination, but mothers in the experimental group were given training course of mother forum. When the child grew up to one year and two months, the child vaccination rate and its timeliness rate were compared. Results The measles vaccination rate in EPI vaccines between the two groups were not significantly different (P>0. 05), but the other five kinds of vaccination rates were higher in the experimental group compared with the control group (χ2 =6. 21-11. 56, P<0. 05). The timeliness vaccination rate in the experimental group were higher than that of the control group (χ2 =7. 05-20. 05, P<0. 01). Three kinds of extra EPI vaccination rates represented the same trend as above (χ2 =39. 45 -164. 45,P<0. 01), and as well as timeliness vaccination rate (χ2 =39. 97 -213. 37, P <0. 01). Conclusions Mother forum can strengthen parental attention to vaccination, and enhance child vaccination rate and the timeliness vaccination rate.
