Background: On the special occasion in celebrating the 60th Birthday of HRH Princess Maha Chakri Sirindhorn’s on April 2, 2015, The MOPH has launched the campaign to give diphtheria and tetanus (dT) immunization in Sing Buri, the project was conducted during January to April, 2015, targeted on 58,000 peoples aged 20-50 years, when likely to have insufficient level of immunity against diphtheria. The objective of this study is to investigated the reasons target set for 85.00% coverage of dT is not successful. Method: This investigate was done by cross #2 sectional survey method with 30 cluster sampling 30 villages/ cluster were selected from 381 villages, and the sample size calculation following the Krejcie & Morgan criteria. These survey were proceeded by interviewing the target population, ≥13 persons per village. The interview period was from June to August, 2015. Results: The results of survey showed that the coverage of dT vaccination campaign is 51.36% (from 841 sampling people), The place most people went for vaccination was Sub District Hospital (50.00% sampling). Majority of those who had been vaccinated (69.21%) had no side effect, while 30.78% have had some mild side effects such as mild fever, and slight pain around the injection sites. The analysis of other factors such as gender, age, marital, status, education and occupation showed that the people aged 40-50 years were vaccinated higher than the 20-30 years age group. The farmers were highest vaccinated than other occupations. There is no statistical significant showing relationship among other factors. This investigation revealed that the primary cause that the unvaccinated people did not come for unvaccination include (1) did not have time or were busy (46.69%) (2) did not know about the dT vaccination campaign. Conclusion: The coverage from this survey is less than from the report. To reach herd immunity of 85.00% coverage the project should be extended, the extension would give advantage for the health officials to reach out and vaccinate the still unvaccinated groups to increase the coverage to the set goal 85.00%. The information of public relation by mass media should be already continued.
