Doctors face-palm as RFK Jr.’s top vaccine advisor questions need for polio shot

He then pondered out loud what would happen if people stopped getting vaccinated. “If we take away all of the herd immunity, then does that switch, does that teeter-totter switch in a different direction?” he asked.

Backlash

In a statement, AMA Trustee Sandra Adamson Fryhofer blasted the question. “This is not a theoretical debate—it is a dangerous step backward,” she said. “Vaccines have saved millions of lives and virtually eliminated devastating diseases like polio in the United States. There is no cure for polio. When vaccination rates fall, paralysis, lifelong disability, and death return. The science on this is settled.”

Fryhofer also took aim at Milhoan’s repeated argument that the focus of vaccination policy should move from population-level health to individual autonomy. Moving away from routine immunizations, which include discussions between clinicians and patients, “does not increase freedom—it increases suffering,” she said, adding that the weakening of recommendations “will cost lives.”

Overall, Milhoan’s comments only further erode the relevance of ACIP and federal vaccine policy among the medical community and states. According to a KFF policy brief, 27 states and Washington, DC, have already announced they will not follow current CDC vaccine recommendations, which Kennedy dramatically overhauled earlier this month without even consulting the ACIP. Instead, the majority of states are relying on previous recommendations or recommendations made within states or by medical organizations.

On Monday, the American Academy of Pediatrics announced the 2026 update to its childhood and adolescent vaccine schedule, which it has held up as an alternative to the CDC’s schedule and has been widely embraced by pediatricians. In the announcement, AAP noted that 12 other medical organizations have endorsed the schedule, including the AMA, the American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, the Infectious Diseases Society of America, and the Pediatric Infectious Diseases Society.

The AAP’s updated recommendations are largely the same as the schedule from last year, but it is significantly different from the CDC’s recommendations, which “depart from longstanding medical evidence and no longer offer the optimal way to prevent illnesses in children,” the AAP said.

“The AAP will continue to provide recommendations for immunizations that are rooted in science and are in the best interest of the health of infants, children and adolescents of this country,” AAP President Andrew Racine said in the announcement.

SC measles outbreak has gone berserk: 124 cases since Friday, 409 quarantined

A measles outbreak in South Carolina that began in October is now wildly accelerating, doubling in just the past week to a total of 434 cases, with 409 people currently in quarantine.

Amid the outbreak, South Carolina health officials have been providing updates on cases every Tuesday and Friday. On Tuesday, state health officials reported 124 more cases since last Friday, which had 99 new cases since the previous Tuesday. On that day, January 6, officials noted a more modest increase of 26 cases, bringing the outbreak total at that point to 211 cases.

With the 3-month-old outbreak now doubled in just a week, health officials are renewing calls for people to get vaccinated against the highly infectious virus—an effort that has met with little success since October. Still, the health department is activating its mobile health unit to offer free measles-mumps-rubella (MMR) vaccinations, as well as flu vaccinations at two locations today and Thursday in the Spartanburg area, the epicenter of the outbreak.

Officials are also warning that they’re losing the ability to trace cases, and exposures are continuing. Last Friday, someone contagious with measles was in the South Carolina State Museum in Columbia between 1 pm and 5 pm ET. Anyone in the museum during that time and unvaccinated is at risk of contracting the infection. The virus spreads through the air and can linger in a room’s airspace for up to two hours after an infected person has left. Measles is so contagious that up to 90 percent of unvaccinated people exposed will fall ill.

Measles continues raging in South Carolina; 99 new cases since Tuesday

The disease usually develops seven to 14 days after an exposure, but it can take up to 21 days (which is the length of quarantine). Once it develops, it’s marked by a high fever and a telltale rash that starts on the head and spreads downward. People are contagious for four days before the rash develops and four days after it appears. Complications can range from ear infections and diarrhea to encephalitis (swelling of the brain), pneumonia, death in up to 3 out of 1,000 children, and, in very rare cases, a fatal neurological condition that can develop seven to 10 years after the acute infection (subacute sclerosing panencephalitis).

Two doses of the measles, mumps, and rubella (MMR) vaccine is considered 97 percent effective against the virus, and that protection is considered lifelong. Ninety-nine percent of the 310 cases in the South Carolina outbreak are in people who are unvaccinated, partially vaccinated, or have an unknown vaccination status (only 2 people were vaccinated).

The Centers for Disease Control and Prevention, which only has data as of January 6, has tallied three confirmed cases for this year (two in South Carolina and one in North Carolina, linked to the South Carolina outbreak). Since then, South Carolina reported 26 cases on Tuesday and 99 today, totaling 125. North Carolina also reported three additional cases Tuesday, again linked to the South Carolina outbreak. In all, that brings the US tally to at least 131 just nine days into the year.

In 2025, the country recorded 2,144 confirmed cases, the most cases seen since 1991. Three people died, including two otherwise-healthy children. In 2000, the US declared measles eliminated, meaning that it was no longer continuously circulating within the country. With ongoing outbreaks, including the one in South Carolina, the country’s elimination status is at risk.

Over 250 people quarantined in South Carolina as measles outbreak rages

The quarantine period for measles is 21 days from the exposure, which is the maximum incubation period before the tell-tale rash appears. Measles is highly infectious, with up to 90 percent of unvaccinated or otherwise vulnerable people contracting the virus upon exposure. People infected with measles are infectious from four days before the rash appears to four days after its onset.

The outbreak is occurring in the northern region of South Carolina, with many cases identified in Spartanburg County, which contains Inman, as well as Greenville County. Both counties have low vaccination rates. For the 2024–2025 school year, only 90 percent of Spartanburg students were vaccinated, while Greenville’s vaccination rate was 92.4 percent. Those numbers are well below the 95 percent target needed to halt community transmission.

The two counties’ low vaccination rates are coupled with high rates of religious exemptions. Spartanburg has the state’s highest rate, with 8.2 percent of students exempt from the school vaccination requirement based on religious beliefs. Neighboring Greenville has a religious vaccination exemption rate of 5.3 percent.

Of the 111 outbreak cases, 105 were unvaccinated, three were partially vaccinated, two had an unknown status, and one case was fully vaccinated.

On a national scale, vaccination rates have declined overall amid misinformation spread by anti-vaccine activists, including current Health Secretary Robert F. Kennedy Jr. As such, measles cases are at a 33-year high, with nearly 2,000 cases this year and 46 outbreaks.

CDC data confirms US is 2 months away from losing measles elimination status

Unsurprising

This 9171 subtype “continues, unfortunately uninterrupted, across multiple jurisdictions,” David Sugerman, who leads the CDC measles response, said on the call.

According to the Times, local health officials are pessimistic that they’ll be able to stamp out the virus’ spread, saying that vaccination efforts have had “limited” impact. As Ars reported previously, vaccination rates are dangerously low in two measles hotspots: northwestern Mohave County, Arizona, and the southwest health district of Utah. Vaccination rates among kindergartners in the 2024–2025 school year were 78.4 percent and 80.7 percent, respectively. That’s well below the 95 percent target needed to keep the virus from spreading onward in the communities.

In addition, public health officials in Arizona and Utah have reported barriers to responding to the outbreak. Around a quarter of cases don’t know how they were exposed, suggesting cases and exposures are being missed. In late October, health officials in Salt Lake County, Utah, said that a person likely infected with measles refused to cooperate with their investigation, leaving them unable to confirm the probable case.

David Kimberlin, who sits on a panel of experts that analyzes measles data for the United States’ elimination status review, told the Times, “It would not surprise me in the least if there’s continued spread across these next several months.”

To date, the CDC  has tallied 1,723 measles cases across 42 states. Most (87 percent) of those cases were linked to outbreaks, of which there have been 45 this year. For context, there were 16 outbreaks and a total of 285 measles cases in the US last year. This year’s measles cases mark a 33-year high.

canada-fought-measles-and-measles-won;-virus-now-endemic-after-1998-elimination

Canada fought measles and measles won; virus now endemic after 1998 elimination

“This loss represents a setback, of course, but it is also reversible,” Jarbas Barbosa, director of PAHO, said in a press briefing Monday.

Call to action

Barbosa was optimistic that Canada could regain its elimination status. He highlighted that such setbacks have happened before. “In 2018 and 2019, Venezuela and Brazil temporarily lost their elimination status following large outbreaks,” Barbosa noted. “Thanks to coordinated action by governments, civil society, and regional cooperation, those outbreaks were contained, and the Region of the Americas regained its measles-free status in 2024.”

On Monday, the Public Health Agency of Canada released a statement confirming that it received notification from PAHO that it had lost its measles elimination status, while reporting that it is already getting to work on earning it back. “PHAC is collaborating with the PAHO and working with federal, provincial, territorial, and community partners to implement coordinated actions—focused on improving vaccination coverage, strengthening data sharing, enabling better overall surveillance efforts, and providing evidence-based guidance,” the agency said.

However, Canada isn’t the only country facing an uphill battle against measles—the most infectious virus known to humankind. Outbreaks and sustained spread are also active in the US and Mexico. To date, the US has documented at least 1,618 measles cases since the start of the year, while Mexico has tallied at least 5,185. Bolivia, Brazil, Paraguay, and Belize also have ongoing outbreaks, PAHO reported.

As of November 7, PAHO has collected reports of 12,593 confirmed measles cases from 10 countries, but approximately 95 percent of them are in Canada, Mexico, and the US. That total is a 30-fold increase compared to 2024, PAHO notes, and the rise has led to at least 28 deaths: 23 in Mexico, three in the United States, and two in Canada.

The PAHO used Canada’s loss as a call to action not just in the northern country, but the rest of the region. “Every case we prevent, every outbreak we stop saves lives, protects families, and makes communities healthier,” Barbosa said. “Today, rather than lamenting the loss of a regional status, we call on all countries to redouble their efforts to strengthen vaccination rates, surveillance, and timely response to suspected cases—reaching every corner of the Americas. As a Region, we have eliminated measles twice. We can do it a third time.”

measles-outbreak-investigation-in-utah-blocked-by-patient-who-refuses-to-talk

Measles outbreak investigation in Utah blocked by patient who refuses to talk

A measles investigation amid a large, ongoing outbreak at the Arizona-Utah border has hit a roadblock as the first probable case identified in the Salt Lake City area refuses to work with health officials, the local health department reported this week.

There have been over 150 cases collectively across the two states, mostly in northwestern Mohave County, Arizona, and the southwest health district of Utah, in the past two months. Both areas have abysmally low vaccination rates: In Mohave County, only 78.4 percent of kindergartners in the 2024–2025 school year were vaccinated against measles, according to state records. In the southwest district of Utah, only 80.7 percent of kindergartners in the 2024–2025 school year had records of measles vaccination. Public health experts say vaccination coverage of 95 percent is necessary to keep the disease from spreading in a community.

While the outbreak has largely exploded along the border, cases are also creeping to the north, toward Salt Lake County, which encompasses the city. Utah County, which sits just south of Salt Lake County, has identified eight cases, including a new case reported today.

Uncooperative case

Salt Lake County likely has a new one, too—the first for the county this year—as well as possible exposures. But, they can’t confirm it.

County health officials said that a health care provider in the area contacted them late on Monday to tell them about a patient who very likely has measles. The officials then spent a day reaching out to the person, who refused to answer questions or cooperate in any way. That included refusing to share location information so that other people could be notified that they were potentially exposed to one of the most infectious viruses known.

“The patient has declined to be tested, or to fully participate in our disease investigation, so we will not be able to technically confirm the illness or properly do contact tracing to warn anyone with whom the patient may have had contact,” Dorothy Adams, executive director of Salt Lake County Health Department, said in a statement. “But based on the specific symptoms reported by the healthcare provider and the limited conversation our investigators have had with the patient, this is very likely a case of measles in someone living in Salt Lake County.”

Measles outbreak in SC sends 150 unvaccinated kids into 21-day quarantine

Health officials in South Carolina are warning that the highly infectious measles virus is spreading undetected in communities in the northern part of the state, specifically Spartanburg and Greenville counties.

Last week, officials in Greenville identified an eighth measles case that is potentially linked to the outbreak. Seven outbreak cases had been confirmed since September 25 in neighboring Spartanburg, where transmission was identified in two schools: Fairforest Elementary and Global Academy, a public charter school.

Across those two schools, at least 153 unvaccinated children were exposed to the virus and have been put in a 21-day quarantine, during which they are barred from attending school, state officials said in a press conference. Twenty-one days is the maximum incubation period, spanning from when a person is exposed to when they would develop a rash if infected.

It’s unclear how the latest case in Greenville became infected with the virus and how they may link to the nearby Spartanburg cases.

“What this case tells us is that there is active, unrecognized community transmission of measles occurring in the Upstate [northern region of South Carolina], which makes it vital to ensure that the public have received their measles vaccinations,” the South Carolina Department of Public Health said in an announcement.

The two recommended doses of the measles, mumps, and rubella (MMR) vaccine are about 97 percent effective at blocking the infection, and that protection is considered lifelong. Without that protection, the virus is extremely contagious, infecting 90 percent of unvaccinated people who are exposed. The virus spreads easily through the air, lingering in the airspace of a room for up to two hours after an infected person has left.

RFK Jr. adds more anti-vaccine members to CDC vaccine advisory panel

Kirk Milhoan, a pediatric cardiologist who is a senior fellow at the Independent Medical Alliance (formerly Front Line COVID-19 Critical Care Alliance), which promotes misinformation about COVID-19 vaccines and touts unproven and dubious COVID-19 treatments. Those include the malaria drug hydroxychloroquine, the de-worming drug ivermectin, and various concoctions of vitamins and other drugs. Milhoan has stated that mRNA COVID-19 vaccines should be removed from the market, telling KFF in March: “We should stop it and test it more before we move forward.”

Evelyn Griffin, an obstetrician and gynecologist in Louisiana who reportedly lost her job for refusing to get a COVID-19 vaccine. In a speech at a Louisiana Health Freedom Day in May 2024, Griffin claimed that doctors “blindly believed” that mRNA COVID-19 vaccines were safe. She has also claimed that the vaccines cause “bizarre and rare conditions,” according to the Post.

Hillary Blackburn, a pharmacist in St. Louis. Reuters reports that she is the daughter-in-law of Sen. Marsha Blackburn (R-Tenn.), who has opposed vaccine mandates.

Raymond Pollak, a semi-retired transplant surgeon who filed a whistleblower lawsuit against the University of Illinois Hospital in 1999, alleging the hospital manipulated patient data to increase their chances of receiving livers. The hospital settled the suit, paying $2.5 million, while denying wrongdoing.

ACIP is scheduled to meet at the end of this week, on September 18 and September 19. According to an agenda recently posted online, the committee will vote on recommendations for a measles, mumps, rubella, and varicella (MMRV) combination vaccine, the Hepatitis B vaccine, and this year’s updated COVID-19 vaccines. Vaccine experts widely fear that the committee will rescind recommendations and restrict access to those vaccines. Such moves will likely create new, potentially insurmountable barriers for people, including children, to get vaccines.

ACIP-recommended vaccines are required to be covered by private health insurance plans and the Vaccines for Children program for Medicaid-eligible and under- or uninsured kids, which covers about half of American children. Without ACIP recommendations for a vaccine, insurance coverage would be an open question, and vulnerable children would simply lose access entirely.

child-dies-of-horrifying-measles-complication-in-los-angeles

Child dies of horrifying measles complication in Los Angeles

A child in Los Angeles has died of a measles-related brain disorder stemming from an infection in infancy, the Los Angeles County health department reported Thursday.

Specifically, the child died of subacute sclerosing panencephalitis (SSPE), a rare but always fatal complication that strikes years after an initial measles infection. The health department’s announcement offered few details about the child, including the child’s age, but said that the child had contracted the virus before they were old enough to be vaccinated against measles. The first of two recommended doses of measles, mumps, and rubella (MMR) vaccine is given between 12 and 15 months.

“This case is a painful reminder of how dangerous measles can be, especially for our most vulnerable community members,” Muntu Davis, a Los Angeles County health officer, said in a statement. “Infants too young to be vaccinated rely on all of us to help protect them through community immunity. Vaccination is not just about protecting yourself—it’s about protecting your family, your neighbors, and especially children who are too young to be vaccinated.”

SSPE is caused by a persistent measles infection in the central nervous system. Children infected with the virus may go through the standard disease progression—flu-like symptoms, high fever, the telltale rash—and then appear to fully recover. But, for a small few, the virus remains, and SSPE emerges years later, often seven to 10 years after the initial infection.

The Los Angeles health department noted that SSPE generally affects about 1 in 10,000 people with measles, but the risk may be much higher—about 1 in 600—for those who get measles as infants, such as the child who recently died.

With widespread vaccination, which led to measles being declared eliminated from the US in 2000, SSPE has virtually disappeared in the US. However, with vaccination rates slipping and anti-vaccine misinformation and views gripping the country, health experts fear seeing more of these devastating cases. Already, the US measles case count for the year is at a 33-year high, and two other children, as well as an adult, died from the acute infection this year.

The West Texas measles outbreak has ended

A large measles outbreak in Texas that has affected 762 people has now ended, according to an announcement Monday by the Texas Department of State Health Services. The agency says it has been more than 42 days since a new case was reported in any of the counties that previously showed evidence of ongoing transmission.

The outbreak has contributed to the worst year for measles cases in the United States in more than 30 years. As of August 5, the most recent update from the Centers for Disease Control and Prevention, a total of 1,356 confirmed measles cases have been reported across the country this year. For comparison, there were just 285 measles cases in 2024.

The Texas outbreak began in January in a rural Mennonite community with low vaccination rates. More than two-thirds of the state’s reported cases were in children, and two children in Texas died of the virus. Both were unvaccinated and had no known underlying conditions. Over the course of the outbreak, a total of 99 people were hospitalized, representing 13 percent of cases.

Measles is a highly contagious respiratory illness that can temporarily weaken the immune system, leaving individuals vulnerable to secondary infections such as pneumonia. In rare cases, it can also lead to swelling of the brain and long-term neurological damage. It can also cause pregnancy complications, such as premature birth and babies with low birth weight. The best way to prevent the disease is the measles, mumps, and rubella (MMR) vaccine. One dose of the vaccine is 93 percent effective against measles while two doses is 97 percent effective.

Under RFK Jr, CDC skips study on vaccination rates, quietly posts data on drop

Vaccination rates among the country’s kindergartners have fallen once again, with coverage of the measles, mumps, and rubella (MMR) vaccination dropping from 92.7 percent in the 2023–2024 school year to 92.5 percent in 2024–2025. The percentage changes are small across the board, but they represent thousands of children and an ongoing downward trend that makes the country more vulnerable to outbreaks.

In the latest school year, an estimated 286,000 young children were not fully protected against measles. At the same time, the country has seen numerous explosive measles outbreaks, with case counts in 2025 already higher than any other year since the highly infectious disease was declared eliminated in 2000. In fact, the case count is at a 33-year high.

The latest small decline is one in a series that is eroding the nation’s ability to keep bygone infectious diseases at bay. In the 2019–2020 school year, 95 percent of kindergartners were protected against measles and other serious childhood diseases, such as polio. That 95 percent coverage is the target that health experts say prevents an infectious disease from spreading in a community. But amid the pandemic, vaccination rates fell, dropping to 93.9 percent MMR coverage in the 2020–2021 year, and have kept creeping downward.

Anti-vaccine era

At the height of the pandemic, some slippage in immunization coverage could be blamed on disrupted access. But anti-vaccine sentiments and misinformation are clearly playing a large role as vaccination continues to decline and access has largely resumed. For the 2024–2025 school year, nonmedical exemptions for childhood vaccinations once again hit a new high. These are exemptions driven by ideology and have risen with the influence of anti-vaccine voices, including current health secretary and fervent anti-vaccine advocate Robert F. Kennedy Jr.
