为了提高免疫接种覆盖率,英国在1990年引入了DTP加速初免程序,将幼儿接种DTP和口服脊髓灰质炎疫苗的年龄从3、4(1/2)～5和8(1/2)～11月龄改为2、3和4月龄。加速程序组幼儿107名,3次免疫时间分别为8、12和16周龄,而对照组115名幼儿仍按原来免疫程序接种,3次免疫时间分别为3、4(1/2)～5和8(1/2)～11月龄。每次免疫后7天内,由孩子父母定时记录腋温和局部红肿大小,再由护士通过访视或电话询问其他特殊
In order to increase immunization coverage, the UK introduced the DTP Accelerated Prophylaxis Program in 1990 to increase the age of young children receiving DTP and oral polio vaccine from 3,4 (1/2) to 5 and 8 (1/2) to 5 11 months old to 2, 3 and 4 months old. In the accelerated group, 107 infants were challenged with the three immunization times of 8, 12 and 16 weeks, respectively. In contrast, 115 infants in the control group were vaccinated according to the original immunization schedule. The three immunizations were 3,4 (1/2) to 5 And 8 (1/2) ~ 11 months of age. Within 7 days after each immunization, the parents of the child regularly record the axillary temperature and local redness size, and then by nurses visit or telephone to ask other special
