U.S. Kindergarten Vaccination Rates Slip As Exemptions Hit Historic High: What It Means for Thailand
Vaccination rates among U.S. kindergarteners have fallen while exemption rates have soared to unprecedented levels, sparking renewed concerns about resurgent vaccine-preventable diseases—a trend with implications far beyond American borders. New data from the U.S. Centers for Disease Control and Prevention (CDC), released in early August 2025, show that inoculation coverage for key childhood diseases has declined again. At the same time, exemptions—parents opting out of required vaccines for their children—have reached an all-time high. The latest snapshot underscores potential threats to herd immunity, with infectious diseases like measles re-emerging at levels not seen in more than 30 years in the United States. The findings highlight not only the direct health risks but also wider social and policy challenges as vaccine hesitancy grows worldwide, including in Thailand.
