The delayed immunization of children of migrant farm workers in South Carolina.
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.
