The alarming drop in childhood vaccination rates is raising fresh fears of infectious disease resurgence in Thailand and around the world. According to recent research highlighted by international health experts, the downward trend in routine immunizations is leaving populations increasingly vulnerable to outbreaks of preventable illnesses such as measles and polio, marking a pivotal moment for public health systems globally, including Thailand (WIRED).

This issue is especially crucial for Thai families and policymakers in the wake of the Covid-19 pandemic, which disrupted health services and shifted public attention away from routine childhood immunizations. Historically, Thailand has celebrated strong immunization coverage, credited with eradicating diseases such as polio within its borders and sharply reducing cases of measles and diphtheria. However, the latest developments suggest these hard-won gains may now be at risk should the pattern mirror the global decline.

Three more US states—Louisiana, Virginia, and Missouri—confirmed their first measles cases of 2025 over the weekend, pushing the current outbreak to over half of all US states and marking one of the most significant resurgences in recent years. According to a report by UPI, the total number of confirmed cases across at least 27 states has climbed to 800, with the vast majority being either unvaccinated or of unknown vaccination status. This growing crisis reflects deeper global trends in vaccine coverage and highlights crucial public health lessons for Thailand, where measles cases have also risen sharply over the last two years (UPI, CDC).
