When a measles outbreak emerged in Spartanburg, South Carolina, in October, health officials announced that most cases were tied to one public charter school, where only 17% of the 605 students enrolled during the 2024-25 academic year provided documentation showing they had received their required vaccinations.
HHS Secretary Robert F. Kennedy Jr. claims that the aluminum ingredients in vaccines cause a variety of harmful reactions, from allergies to autism. Scientists say that’s wrong and warn of risks if they’re removed. Here are some of the basics.
A reshaped CDC website suggesting that vaccines cause autism has appalled the medical community.
Fueled by covid backlash, a libertarian author created the Brownstone Institute in 2021. In recent months, people with ties to the group have catapulted to the highest levels of U.S. government, exercising significant authority over access to vaccines and scientific research.
The study sought to answer questions about how breast cancer risk differs by type of hormonal contraceptive. Doctors say the results won’t change how they counsel patients.
Florida’s surgeon general, spiritual healers, and Trump allies push their cures in a swampy outpost of anti-government absolutism and mystical belief.
Florida has announced plans to end mandatory vaccination. Now scientists are assessing which of several diseases deadly to children — whooping cough, measles, polio, rubella, mumps, diphtheria, and tetanus — are likely to make a resurgence and when.

The idea that airplane vapors are toxic to people or that there are ongoing efforts to intentionally change the climate made the social media rounds. Now, it has found advocates at the Department of Health and Human Services.
Immigrants living in the U.S. without legal status are generally ineligible for federally funded health care programs. Democrats’ funding proposal would restore access to Medicaid and the Affordable Care Act marketplace for legal immigrants who will lose access once certain provisions of the Republicans’ tax and spending law take effect.
The evidence is unequivocal: Vaccines do not cause autism. Yet adding autism to the list of conditions covered by a federal payout program, as health secretary Robert F. Kennedy Jr. seems inclined to do, could threaten its financial viability. Such a move also would suggest that the science is unsettled, that vaccines may be riskier than diseases, which is a fallacy.
At a recent meeting of a key vaccine advisory panel, members debated changes to the timing of hepatitis B vaccination, while largely ignoring the risk of early childhood transmission from day care or household contact. A few days later, President Donald Trump did the same.
In a rambling news conference that shocked public health experts, President Donald Trump — without scientific evidence — blamed the over-the-counter drug acetaminophen, and too many childhood vaccines, for the increase in autism diagnoses in the U.S. That came days after a key immunization advisory panel, newly reconstituted with vaccine doubters, changed several long-standing recommendations. Former Centers for Disease Control and Prevention official Demetre Daskalakis joins KFF Health News’ Julie Rovner to discuss those stories. Meanwhile, Sandhya Raman of CQ Roll Call and Anna Edney of Bloomberg News join Rovner with the rest of the news, including a threat by the Trump administration to fire rather than furlough federal workers if Congress fails to fund the government beyond the Oct. 1 start of the new fiscal year.
Doctors say acetaminophen, the main ingredient in Tylenol, is safe to take during pregnancy. Other over-the-counter pain relievers such as aspirin and ibuprofen aren’t recommended because they can harm fetal development. Untreated fever in pregnancy can pose maternal and fetal health risks.
The White House’s autism announcement exaggerates links to Tylenol, misleads on vaccines, and sets back the field by ignoring decades of research, scientists say.
A Centers for Disease Control and Prevention meeting on vaccines pitted scientific expertise against vaccine skepticism. An often confusing debate ended with critics of the current vaccine schedule tabling a vote to remove one of its cornerstones.
A lack of faith in the soundness of the Centers for Disease Control and Prevention’s new direction has led states to explore enacting their own vaccine policies. A patchwork of divergent recommendations and requirements could result.
A federal vaccine panel, recently reshaped by Health and Human Services Secretary Robert F. Kennedy Jr., is expected to vote on delaying the hepatitis B shot for newborns. Pediatricians warn that could open the door to a comeback for a disease virtually eradicated among U.S. children.
Although the FDA has approved the vaccines for anyone 65 or older and anyone at least 6 months old who is at risk of a severe covid infection, barriers to coverage and access persist.
As extremism and radicalization worsen in the United States, a group of researchers is trying out a new approach that addresses the issue as a public health problem.
