Abstract The objective of this project was to document and increase vaccine coverage in migrant school children on the Thailand-Myanmar border. Migrant school children (n = 12,277) were enrolled in a school-based immunization program in four Thai border districts. The children were evaluated for vaccination completion and timing, for six different vaccines: Bacille Calmette-Guerin (BCG); Oral Polio vaccine (OPV); Hepatitis B vaccine (HepB); Diphtheria, Pertussis and Tetanus vaccine (DTP); Measles Containing Vaccine or Measles, Mumps and Rubella vaccine (MMR); Tetanus and Diphtheria containing vaccine (Td). Vaccine coverage proportions for BCG, OPV3, DTP3, HepB3 and measles containing vaccine were 92.3, 85.3, 63.8, 72.2, and 90.9 % respectively. Most children were able to receive vaccines in a time appropriate manner. School-based immunization programs offer a suitable vaccine delivery mechanism for hard-to-reach populations. However, these data suggest overall low vaccine coverage in migrant populations. Further efforts toward improving
appropriate vaccine coverage and methods of retaining documentation of vaccination in mobile migrant populations are necessary for improved health. Keywords Immunization Vaccine coverage Migrant children School
Introduction Immunization is one of the most successful and cost-effective health interventions of modern medicine, preventing an estimated 2.5 million deaths each year [1]. Vaccine preventable diseases and disabilities have decreased drastically over the last several decades, resulting in healthier children and, subsequently, adults [2]. Despite this progress, vaccine preventable diseases are still a major cause of morbidity and mortality in low and middle income countries [1] and several studies [3–5] have investigated
