A groundbreaking U.S. government study has found that a single dose of the human papillomavirus (HPV) vaccine may be just as effective at preventing HPV infection as the traditional two-dose regimen, according to new data presented this week. The findings could dramatically reshape vaccination strategies worldwide, including policies and practices in Thailand, where increasing HPV vaccine uptake remains a crucial public health goal.

The new results, unveiled by U.S. government researchers, have been described by experts as “phenomenal,” underscoring the potential for a single-dose schedule to maintain protection against the most common and cancer-causing strains of HPV. The research, detailed in a highly anticipated STAT News report, adds to growing evidence that simplifying the HPV vaccine protocol could enhance global vaccination rates, lower health care costs, and ultimately save more lives.

A recent report on cancer prevention trends in the United States has delivered both hopeful and concerning findings: while smoking rates continue their historic decline, vaccination rates against human papillomavirus (HPV)—a leading cause of cervical and other cancers—have stalled. This research carries important lessons for Thailand, where cancer remains a leading cause of death and where public health campaigns must juggle both familiar and emerging risks (CNN, 2025).

The continued drop in smoking rates is seen as a major victory for US public health. Decades of anti-smoking campaigns, policy changes, and increased public awareness have pushed adult smoking rates in the US to all-time lows. Globally, the World Health Organization (WHO) points to similar downward trends in high- and some middle-income countries, though progress is uneven. In Thailand, while smoking rates have decreased somewhat—especially among women and urban youth—a significant portion of the male population still uses tobacco products. According to the Ministry of Public Health, about 17% of Thais over 15 are smokers, higher than the current US adult smoking rate of around 11% (Thai National Statistics Office, 2023; CDC, 2024). This positions the new US numbers as benchmarks for Thai policymakers, especially as tobacco-related cancers continue to challenge the country’s healthcare system.
