#VaccineHesitancy

Billionaire philanthropist and global health advocate Bill Gates has voiced deep concerns over the rapidly growing anti-vaccine sentiment in the United States, warning that the spread of vaccine skepticism abroad could result in a greater loss of life in developing countries than within American borders. Speaking at a recent event in Cambridge, Massachusetts, Gates cautioned that exporting such unfounded fears threatens hard-won progress on preventing deadly diseases like measles and undermines decades of international public health achievements (STAT News).

A surge of anti-vaccine narratives originating abroad threatens Thailand’s hard-won public health gains. Global health leaders warn that misinformation travels quickly through social media, exploiting local concerns and undermining decades of progress in childhood vaccination. In Thailand, these dynamics risk reversing hard-won reductions in fever, paralysis, and infectious disease, placing thousands of Thai children at needless risk.

Thailand has achieved remarkable milestones in immunization, reducing measles deaths and maintaining polio-free status since 1995. These successes resulted from sustained investments in healthcare infrastructure, community education, and strong trust in vaccination programs. But imported misinformation now strains this foundation, spreading unfounded fears about vaccine safety and effectiveness that challenge local decision-making.

Thailand’s remarkable success in eliminating deadly childhood diseases faces an unprecedented threat from an unexpected source: the exportation of American anti-vaccine conspiracy theories that could unravel decades of public health progress and condemn thousands of Thai children to preventable deaths, according to urgent warnings from global health leaders including billionaire philanthropist Bill Gates. Speaking at a recent public health forum in Cambridge, Massachusetts, Gates delivered a stark assessment that vaccine skepticism originating in wealthy Western countries kills more children in developing nations than in the countries where these dangerous ideas first emerge, creating a global crisis that could reverse Thailand’s celebrated achievements in disease eradication and childhood mortality reduction.

A landmark study published in The Lancet warns that after five decades of steady gains, childhood vaccination coverage is stalling or declining worldwide. The analysis draws on 50 years of country-level data and highlights a troubling rise in “zero-dose” children—those missing even the most basic vaccines. Inequalities, lingering COVID-19 disruptions, and increasing vaccine misinformation are contributing to uneven progress, according to the study led by researchers at the University of Washington’s Institute for Health Metrics and Evaluation and supported by the Gates Foundation and Gavi.

A new comprehensive study published in The Lancet has sounded a worldwide alarm: after five decades of progress, childhood vaccination coverage is stagnating or even retreating, leaving millions of children increasingly vulnerable to deadly yet preventable diseases. The analysis, released this week and drawing on 50 years of country-level data, warns that the number of “zero-dose” children—those missing even the most basic vaccines—remains distressingly high, with global immunisation efforts hampered by growing inequalities, the lasting shocks of the COVID-19 pandemic, and an upsurge in vaccine hesitancy and misinformation (Washington Post; The Lancet).

A resurgence of ancient medical ideas is reshaping public health discourse in unexpected ways, as evidenced by recent moves in the United States under Health Secretary Robert F. Kennedy Jr. Drawing on the centuries-old miasma theory—which proposes that diseases arise from “bad air” or pollution—Kennedy has implemented policies and made public statements that challenge the contemporary scientific consensus around vaccines. The revival of this long-discredited framework echoes far beyond American borders, offering important lessons for Thailand as it contends with its own vaccine hesitancy and public health challenges (NPR).

Public health debates are increasingly shaped by old ideas resurfacing in new forms. In the United States, Health Secretary Robert F. Kennedy Jr. has sparked discussions by revisiting miasma-era thinking that disease comes from polluted air and the environment. His statements and policies emphasize environmental factors and immune strengthening over vaccination, prompting concern among infectious disease experts and offering Thai readers a lens to understand vaccine hesitancy at home.

The miasma concept originated with ancient Greek physicians, including Hippocrates, and once guided sanitation efforts by linking disease to foul air. While it helped prompt cleaner cities, the theory was displaced by germ theory in the 19th century, a shift that underpins today’s vaccines and antibiotics. As data show, vaccines dramatically reduce disease and save lives, a point echoed by Thai health officials who maintain strong immunization programs amid ongoing public dialogue.

In a sobering assessment this week, a leading US infectious disease expert declared that the world may have moved into a “post-herd immunity” era for measles, as vaccination gaps spark resurgent outbreaks across multiple countries. The statement comes as the United States faces its worst measles outbreak in decades, with more than 930 cases reported this year alone—a harbinger that the protective barrier of community immunity is crumbling (The Guardian, MSN).

A leading US infectious disease expert warns the world may have entered a “post-herd immunity” era for measles as vaccination gaps spark renewed outbreaks. The United States is contending with its worst measles surge in decades, with more than 930 cases reported this year. The warning underscores how gaps in vaccination can erode community protection and fuel transmission even in previously controlled regions.

For Thai readers, this development matters because declining vaccine coverage worldwide raises the risk of measles returning to countries that had long controlled the disease. Measles had been declared eliminated in many regions thanks to sustained vaccination campaigns, but recent disruptions and misinformation have dented uptake. In the United States and parts of Europe, vaccination rates have fallen below the 95 percent threshold needed for herd immunity, raising concerns about localized outbreaks and spillover to other regions, including Southeast Asia.

A viral personal account about growing up with anti-vaccine parents has sparked renewed debate on vaccine hesitancy and its real-world consequences. The piece, originally published by BuzzFeed as “17 Brutally Honest Confessions From A Woman Who Was Raised By Anti-Vax Parents,” offers a candid look at how parental skepticism can shape a child’s health, education, and social life. The narrative resonates in Thailand, where vaccine debates exist alongside strong public health achievements.

A recent viral personal account has reignited the debate over vaccine hesitancy, shining a spotlight on the real-life consequences faced by those raised in anti-vaccination households. The article, published by BuzzFeed and titled “17 Brutally Honest Confessions From A Woman Who Was Raised By Anti-Vax Parents,” offers a candid look at how parental skepticism toward vaccines can shape every facet of a child’s development—physically, emotionally, and socially. Its frank revelations underscore issues of public health and personal risk that resonate worldwide, including in Thailand, where anti-vaccine sentiment has gained traction in some circles.

The specter of polio, a disease once on the brink of global eradication, is looming large yet again as new reports from 2025 reveal troubling spikes in Afghanistan and Pakistan, compounded by global aid disruptions and vaccine skepticism1. For Thai readers, these developments sound an urgent warning: even diseases thought to be “conquered” can return if public health vigilance lapses, offering a stark lesson relevant to Thailand’s ongoing immunization efforts and pandemic preparedness.

Polio, once nearing global eradication, now faces renewed risk as reports from 2025 highlight spikes in Afghanistan and Pakistan. The disruptions to aid campaigns and rising vaccine skepticism threaten progress and offer a crucial lesson for Thailand’s immunization and pandemic preparedness.

Despite decades of effort, polio has never fully left the world. The latest warnings focus on Pakistan and Afghanistan—the last two nations with active wild polio transmission. In 2024, Pakistan saw a sharp rise in cases, while Afghanistan reported dozens of infections, underscoring how operational challenges and vaccination gaps persist. Early 2025 figures show continued, though smaller, case numbers, reminding health officials that the virus can rebound with the right conditions.
