#Vaccines

A newly released autism-focused report from a vocal anti-vaccine activist figure has ignited a fresh debate about how data is interpreted in public health. The piece argues that vaccines cause autism by presenting associations as if they demonstrate a direct, causal link. Scientists and health authorities, however, say the report misreads epidemiological signals, confuses correlation with causation, and risks sowing fear where the evidence remains overwhelmingly aligned with safety and efficacy of vaccines. In Thailand, where immunization is a central pillar of child health and a topic of continual public interest, the controversy adds another layer to a long-running conversation about how to navigate competing claims in a landscape crowded with social media chatter, political rhetoric, and genuine concern from families.

A new Washington Post–KFF poll reveals a troubling shift in the United States: about one in six parents have delayed or skipped some vaccines for their children, excluding COVID-19 and flu shots. Nine percent have skipped the polio or measles, mumps, and rubella (MMR) vaccines. In a nation where routine childhood immunization has long been a bedrock of public health, the findings mark a significant tilt away from consensus and toward cautious hesitation. For Thai readers, the study offers a mirror to reflect on how trust, risk communication, and cultural values shape decisions about vaccines in a densely interconnected world.

A quiet revolution is taking shape in the science of cancer prevention. Scientists are increasingly arguing that the most effective way to stop cancers may be to target the immune system itself, intercepting premalignant changes long before a tumor can form. This approach, called immunoprevention or immune interception, shifts the focus from treating mutations in cancer cells to fortifying the body’s own defenses against malignant transformation. If proven safe and scalable, immunoprevention could transform how Thailand, like many countries, confronts one of the nation’s most serious health challenges: cancer.

A recent fact-checking wave around a high-profile claim that pediatricians are paid to recommend vaccines has clarified a long-standing misunderstanding: in most real-world medical settings, doctors vaccinate because vaccines protect children, not to line their pockets. A close review of how vaccines are shipped, stored, and reimbursed shows that pediatric practices often spend money on vaccines up front and rely on reimbursement patterns that rarely generate profit. In other words, the notion that doctors push vaccines for financial gain does not hold up against the evidence and the everyday economics of pediatric care.

China’s aggressive response to a fast-moving chikungunya outbreak in Guangdong province — from drone patrols and fines for standing water to reports of enforced isolation — has drawn international attention, and with good reason. The mosquito-borne chikungunya virus (CHIKV) is causing large outbreaks across several continents in 2025, with global case counts in the hundreds of thousands and new local transmission reported in places as far afield as Europe and the Americas. Although chikungunya is rarely fatal, its abrupt, debilitating joint pain, potential for long-lasting disability, and the presence of competent mosquito vectors across Southeast Asia make the disease an urgent public-health concern for Thailand’s health authorities, travellers and communities who depend on tourism. Recent official updates, scientific guidance and media investigations together outline the scope of the current epidemic, the tools available to fight it, and practical steps Thai readers should take now to reduce risk at home and when travelling.

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 large Danish study finds no increased risk of autism, ADHD, or other chronic neurological, autoimmune, or allergic conditions from aluminum in vaccines. Researchers analyzed health records of more than 1.2 million children born between 1997 and 2018, following them for up to eight years and examining fifty conditions. The findings provide solid reassurance to Thai families amid ongoing concerns about vaccines.

Aluminum salts act as adjuvants, helping vaccines provoke a stronger immune response. This practice has been in use for more than nine decades. While rumours circulate online, global science has not supported a causal link between aluminum exposure in vaccines and neurodevelopmental or immune-related disorders.

A sweeping new study out of Denmark has concluded that exposure to aluminum in early childhood vaccines does not increase the risk for autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), or other chronic neurological, autoimmune, or allergic conditions. This research, covering more than 1.2 million children, comes at a crucial time of persistent vaccine hesitancy and misinformation, offering robust scientific reassurances that routine childhood immunisations are safe and not a source of neurological or immune harm.

A regional milestone in 2024 shows South Asia achieving the highest-ever immunization coverage for children. The joint findings from the World Health Organization and UNICEF signal a turning point for the region and offer practical lessons for Thailand as it strengthens protections against vaccine-preventable diseases.

The achievement reflects a broad partnership among governments, frontline health workers, donors, and communities. Early indicators from Thailand’s health authorities echo a shared drive across South Asia—covering Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka—that lifted vaccine uptake. A UNICEF regional director calls this a proud moment, noting that more children are protected today thanks to dedicated health workers, strong leadership, and family trust.

South Asia has achieved a remarkable public health milestone in 2024, reaching its highest-ever immunization coverage for children, according to newly released data from the World Health Organization (WHO) and UNICEF. The news marks a turning point not only for the region but also offers valuable lessons for countries like Thailand as they strive to strengthen child health and protection against vaccine-preventable diseases.

At the heart of this achievement lies a powerful collaboration between governments, frontline health workers, international donors, and the communities themselves. Early results released by WHO Thailand on July 16, 2025, highlight the collective push across South Asia – which includes Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka – that led to a dramatic increase in vaccine coverage. According to UNICEF’s Regional Director for South Asia, “This is a proud moment for South Asia. More children are protected today than ever before, thanks to tireless frontline health workers, strong government leadership, donors’ and partners’ support and the unwavering trust of families.”

A growing body of research reveals that vaccines may deliver far more than protection against specific infectious diseases; they can also trigger broader immune system responses that benefit general health and survival, especially among children. These “non-specific effects”—sometimes called “bonus shots”—recently made headlines in a detailed feature on Salon.com, which highlighted a wave of new scientific findings and renewed international debate. For Thailand, where high childhood immunisation rates have underpinned rising life expectancies for decades, these revelations add new urgency and context to national vaccine policy.

Vaccines could do more than protect against a single infection. Recent research suggests some vaccines may strengthen overall immune health, potentially benefiting children beyond the targeted diseases. In Thailand, this idea is reshaping discussions about child-immunization programs and how schedules might adapt in the future.

Live vaccines, including BCG for tuberculosis and the measles vaccine, have shown associations with lower mortality from a variety of causes not limited to the diseases they prevent. Researchers emphasize that these broader benefits may stem from how vaccines train the immune system. Thai health professionals are exploring what this could mean for vaccination timing, policy decisions, and parental choices.

A sweeping new international study has found that emergency vaccination programmes launched to counter outbreaks of Ebola, measles, cholera, yellow fever, and meningitis have slashed global deaths and infections from these deadly diseases by nearly 60% over the last 23 years. Researchers say the impact does not stop with lives saved—swift vaccine deployment has yielded economic savings estimated at billions of dollars, marking vaccines as not only a public health triumph but also a cost-effective shield against disruptive epidemics (BBC News).

A major international study finds that rapid vaccination responses to outbreaks of Ebola, measles, cholera, yellow fever, and meningitis have cut global deaths and infections by about 60% over 23 years. Beyond saving lives, swift campaigns also prevent disruptions to health systems and protect economic productivity in communities.

The analysis spans 210 outbreak responses across 49 countries from 2000 through 2023. It shows that fast vaccine deployment not only reduces transmission and fatalities but also prevents subsequent waves that strain health services. Thailand, with substantial vaccination investments, can draw important lessons for dengue, measles, and emerging health threats.

A U.S. federal advisory panel advising the CDC recommended that flu vaccines in the United States be available in single-dose, thimerosal-free formats. If adopted, this would standardize vaccines and address public concerns about ingredients. The issue holds global relevance for Thailand’s immunization programs and public confidence in vaccination.

Thimerosal has long sparked debate over mercury exposure and vaccine safety. The advisory panel, refreshed under new leadership, placed the question of thimerosal at the forefront of its agenda. The move reflects public demand for clearer policies rather than evidence of harm and aligns with the FDA’s position that thimerosal has a long history of safe use as a preservative.

A federal advisory committee to the US Centers for Disease Control and Prevention (CDC) has recommended that all Americans—including children, pregnant women, and adults—receive single-dose influenza vaccines that do not contain thimerosal, a mercury-based preservative long scrutinized despite decades of safe use. This move, which could soon lead to an official CDC policy, reflects an ongoing international spotlight on vaccine ingredients and the public’s persistent concern over vaccine safety—a topic with direct relevance for Thailand’s immunization practices and public confidence.

A recent vote by a United States government advisory panel to curtail the use of thimerosal—a mercury-based preservative—in flu vaccines has reignited controversy over vaccine safety and the legacy of discredited autism claims. The vote, which followed a presentation by prominent vaccine critics now serving in government, illustrates how decades-old debates over vaccine ingredients continue to influence public health policy, even as the global consensus remains firm on vaccine safety.

A U.S. advisory panel has voted to limit thimerosal, a mercury-based preservative, in flu vaccines. The decision revives a long-running debate about vaccine ingredients and safety, even as major health authorities maintain that vaccines containing thimerosal are safe at the doses used.

For Thai readers, the story underscores how misinformation can influence health choices and how public trust in vaccines must be protected. Thailand’s vaccination programs rely on international guidance and local communication to keep campaigns effective. The Thai public health system continues to monitor global debates while ensuring vaccines remain accessible and trustworthy.

Many older Thais have consistently sought out vaccinations for diseases like shingles, influenza, and pneumonia—a strategy that is increasingly validated by a wave of new international research that also carries critical implications for the Kingdom’s rapidly aging society. These findings not only reinforce the wisdom of vaccine compliance among Thailand’s elderly populations but reveal surprising new benefits, including a reduced risk of dementia, according to recent studies published and reported globally, most notably in a major New York Times article.

A growing body of international research reinforces a simple truth many Thai seniors already practice: vaccines protect more than you might expect. Beyond preventing shingles, flu, and pneumonia, new studies suggest vaccines may also lower dementia risk. This has important implications as Thailand’s population ages rapidly.

Across the globe, older adults are increasingly receptive to vaccination. In Thailand, the Ministry of Public Health reports consistently high influenza vaccine uptake among people over 65, contributing to fewer deaths from preventable diseases during flu seasons. Recent analyses add depth, suggesting vaccines may offer broader protection, including cognitive benefits.

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.
