A study was conducted to evaluate the immunization status of migrant farm worker children in South Carolina. Results of this study indicate that the children receive their immunizations at times which are significantly later than the recommended schedule. The first, second, third, and fourth oral poliomyelitis vaccine (OPV) doses are being given approximately 10, 15, 23, and 32 months late, respectively. Diphtheria, pertussis, tetanus vaccine (DPT) is likewise late with the first, second, third, and fourth doses occurring 9, 14, 20, and 26 months late. The fifth booster dose in both series was timed properly. The mumps, measles, rubella vaccine (MMR) is approximately 28 months late, on average. An evaluation of antibody status of 41 migrant farm worker children (5-10 years old) revealed that, even with aberrant patterns of administration, all children had adequate antibody titers. These data indicate that, although adequate levels of protection are reached with the pattern of immunization that migrant farm worker children have, there are large groups of children that are unprotected early in life when they are most susceptible to these diseases.
一项研究旨在评估南卡罗来纳州流动农场工人子女的免疫接种状况。该研究结果表明，这些儿童接种疫苗的时间明显晚于推荐时间表。口服脊髓灰质炎疫苗（OPV）的第一、二、三、四剂接种时间分别晚约10、15、23和32个月。白喉、百日咳、破伤风疫苗（DPT）同样延迟，第一、二、三、四剂接种时间分别晚9、14、20和26个月。两个系列中的第五剂加强针接种时间合适。腮腺炎、麻疹、风疹疫苗（MMR）平均延迟约28个月。对41名流动农场工人子女（5至10岁）的抗体状况评估显示，即使接种模式异常，所有儿童的抗体滴度都足够。这些数据表明，尽管流动农场工人子女的免疫接种模式能达到足够的保护水平，但仍有大量儿童在生命早期最易感染这些疾病时未得到保护。
