[A study on immunization of polio vaccine. II. Comparison of responses obtained by different forms of polio vaccine].

A comparison study on the responses to the immunization of three different forms of polio vaccine, eg. Liquid I, Oral dragee candy I and Trivalent Oral dragee candy, on the susceptible children of 2-6 month of age was conducted in wujin County, Jiangsu Province The study showed no statistical difference between the responses to the three forms of the vaccine reaching 95-100%. For antibody GMT, Liquid I was the highest, with little difference between Liquid I and Oral dragee candy I and Trivalent Oral dragee candy vaccine in statistics. But, there was a significant statistical difference between Trivalent Oral dragee candy and Liquid I. Considering that it is not easy to inoculate the children of 2-4 months of age with oral dragee candy vaccine, it is suggested all the producers try their best to convert the present oral dragee candy form into Liquid.
