Objective: The purpose of this study was to examine barriers to childhood vaccination in three different groups (general population, socially vulnerable group, internet community).
Methods: We constructed a database of the unvaccinated management system that was integrated and managed by the Korea Centers for Disease Control and Prevention (KCDC). We also analyzed internet community data generated by people who decided against vaccination. Keyword network analysis was conducted to visualize the main keywords derived from the barriers set by the guardians of unvaccinated children.
Results: In the general population, more than 50% of the subjects answered that ‘living outside of Korea’ is the main cause of non-vaccination. In the same group 26.4% refused vaccination. In the socially vulnerable groups, the top ranking reason for refusal were ‘not contacted’, ‘delayed vaccination for health problem’, ‘overseas residence’ and ‘departure’. In the internet community analysis, vaccine safety, unnecessary of vaccine and freedom of choice were the main reasons for refusing vaccination. Keyword analysis was used to visualize the analysis result more intuitively. The analysis highlighted main keywords such as ’atopy’, ’fatigue’, ’allergy’, ’cold’, ’pneumococcus’, ’chicken pox’.
Conclusion: In conclusion, tailor-made strategies for target populations would be needed to improve overall vaccination rates for the various vulnerable groups. To do this, it is necessary to categorize each vulnerable group who decided against immunization. An evidence based strategy should be established to bring about belief and behavioral changes at the individual level, based on the identifying factors affecting immunization in each group. In addition, considering the reality and limited resources of Korea’s medical system, the most cost effective vaccination policy should be planned.
