US measles outlook is so bad health experts call for updating vaccine guidance

With measles declared eliminated from the US in 2000 and national herd immunity strong, health experts have recommended that American children get two doses of the Measles, Mumps, and Rubella (MMR) vaccine—the first between the ages of 12 and 15 months and the second between the ages of 4 and 6 years, before they start school.

Before 12 months, vulnerable infants in the US have been protected in part by maternal antibodies early in infancy as well as the immunity of the people surrounding them. But if they travel to a place where population immunity is unreliable, experts recommend that infants ages 6 to 11 months get an early dose—then follow it up with the standard two doses at the standard times, bringing the total to three doses.

The reason they would need three—and the reason experts typically recommend waiting until 12 months—is because the maternal antibodies infants carry can interfere with the vaccine response, preventing the immune system from mounting long-lasting protection. Still, the early dose provides boosted protection in that 6-to-11-month interval.

In the past, this early, extra dose was recommended for infants traveling internationally—to countries that hadn’t achieved America’s enviable level of herd immunity and were vulnerable to outbreaks. But now, with US vaccination rates slipping, herd immunity becoming spotty, cases rising by the day, and outbreaks simmering in multiple states, the US is no longer different from far-off places that struggle with the extremely infectious virus.

In an article published today in JAMA, prominent health experts—including former Centers for Disease Control and Prevention Director Rochelle Walensky—call for the US to update its MMR recommendations to include the early, extra dose for infants who are not only traveling abroad, but domestically, to any areas where measles is a concern.

“With some local immunization levels inadequate to avert outbreaks and ongoing disease spread in various regions of the country, a dichotomy between domestic and international travel is not appropriate,” the experts write. “For many travel itineraries, there may even be a higher risk of measles exposure at the US point of departure than at the international destinations.”

Vaccinating at-risk infants early is critical to their own health—as well as the people around them, the experts note. “[I]nfants younger than one year face a heightened risk of severe measles-related complications such as pneumonia, encephalitis, and death. Younger infants are also at increased risk of developing subacute sclerosing panencephalitis (SSPE), a rare measles complication that has a high fatality rate and may surface years after initial infection,” according to the experts.

Texas measles outbreak spills into third state as cases reach 258

Texas and New Mexico

Meanwhile, the Texas health department on Tuesday provided an outbreak update, raising the case count to 223, up 25 from the 198 Texas cases reported Friday. Of the Texas cases, 29 have been hospitalized and one has died—a 6-year-old girl from Gaines County, the outbreak’s epicenter. The girl was unvaccinated and had no known underlying health conditions.

The outbreak continues to be primarily in unvaccinated children. Of the 223 cases, 76 are in ages 0 to 4, and 98 are between ages 5 and 17. Of the cases, 80 are unvaccinated, 138 lack vaccination status, and five are known to have received at least one dose of the Measles, Mumps, and Rubella vaccine.

One dose of MMR is estimated to be 93 percent effective against measles, and two doses offer 98 percent protection. It’s not unexpected to see a small number of breakthrough cases in large, localized outbreaks.

Across the border from Gaines County in Texas sits Lea County, where New Mexico officials have now documented 32 cases, with an additional case reported in neighboring Eddy County, bringing the state’s current total to 33. Of those cases, one person has been hospitalized and one person (not hospitalized) died. The death was an adult who did not seek medical care and tested positive for measles only after death. The cause of their death is under investigation.

Of New Mexico’s 33 cases, 27 were unvaccinated and five did not have a vaccination status, and one had received at least one MMR dose. Eighteen of the 33 cases are in adults, 13 are ages 0 to 17, and two cases have no confirmed age.

On Friday, the Centers for Disease Control and Prevention released a travel alert over the measles outbreak. “With spring and summer travel season approaching in the United States, CDC emphasizes the important role that clinicians and public health officials play in preventing the spread of measles,” the agency said in the alert. It advised clinicians to be vigilant in identifying potential measles cases.

The agency stressed the importance of vaccination, putting in bold: “Measles-mumps-rubella (MMR) vaccination remains the most important tool for preventing measles,” while saying that “all US residents should be up to date on their MMR vaccinations.”

US health secretary and long-time anti-vaccine advocate Robert F. Kennedy Jr, meanwhile, has been emphasizing cod liver oil, which does not prevent measles, and falsely blaming the outbreak on poor nutrition.

Measles outbreak hits 208 cases as federal response goes off the rails

autism, health, Infectious disease, measles, MMR, New Mexico, Science, texas, vaccination / Beth Washington / March 8, 2025

Vitamin A is a fat-soluble vitamin that stays in the body. Taking too much over longer periods can cause vomiting, headache, fatigue, joint and bone pain, blurry vision, and skin and hair problems. Further, it can lead to dangerously high pressure inside the skull that pushes on the brain, as well as liver damage, confusion, coma, and other problems, according to the American Academy of Pediatrics.

Nevertheless, in an interview with Fox News this week, Kennedy endorsed an unconventional regimen of a steroid, an antibiotic and cod liver oil, praising two Texas doctors for giving it to patients. One of the doctors Kennedy championed was disciplined by the state medical board in 2003 for “unusual use of risk-filled medications,” according to a report by CNN.

In a yet more worrying sign, Reuters reported Friday afternoon that the CDC is planning to conduct a large study on whether the MMR vaccine is linked to autism. This taxpayer-funded effort would occur despite the fact that decades of research and numerous high-quality studies have already been conducted—and they have consistently disproven or found no connection between the vaccine and autism.

The agency’s move is exactly what Democratic senators feared when Kennedy was confirmed as the country’s top health official. In Senate hearings, Kennedy refused to say that vaccines do not cause autism. Democratic senators quickly warned that his anti-vaccine stance could not only move the country backward in the fight against vaccine-preventable diseases, but also hold back autism research aimed at finding the real cause(s) as well as better treatments.

“When you continue to sow doubt about settled science it makes it impossible for us to move forward,” Senator Maggie Hassan (D-N.H.) said in a Senate hearing. “It’s the relitigating and rehashing … it freezes us in place.”

Texas official warns against “measles parties” as outbreak keeps growing

health, Infectious disease, measles, outbreak, texas, vaccination / Kelly Newman / March 1, 2025

Cook, along with Lubbock’s director of public health, Katherine Wells, said they see no end in sight for the outbreak, which now spans nine counties in Texas, many of which have low vaccination rates. “This outbreak is going to continue to grow,” Wells said, declining to forecast how high the final case count could go after a reporter raised the possibility of several hundred.

So far, 116 of the 146 cases are under the age of 18, with 46 being between the ages of 0 and 4. Only five of the 146 were vaccinated with at least one dose of the Measles, Mumps, and Rubella (MMR) vaccine.

Messaging

On a more positive note, Wells reported that the outbreak has seemed to sway some vaccine-hesitant parents to get their children vaccinated. Just yesterday in Lubbock, over 50 children came into the city’s clinic for measles vaccines. Eleven of those children had vaccine exemptions, meaning their parents had previously gone through the state process to exempt their child from having to receive routine childhood vaccines to attend school. “Which is a really good sign; that means our message is getting out there,” Wells said.

So far in the outbreak, which erupted in late January, messaging about the disease and the importance of vaccination has exclusively come from state and local authorities. The Centers for Disease Control and Prevention only released a brief statement late Thursday, which was not sent through the agency’s press distribution list. It did, however, note that “vaccination remains the best defense against measles infection.”

During a cabinet meeting Wednesday, US Health Secretary and anti-vaccine advocate Robert F. Kennedy Jr. responded to a question about the outbreak, offering a variety of inaccurate information. Kennedy downplayed the outbreak, falsely claiming that “it’s not unusual.” But, this is an unusual year for measles in the US. As epidemiologist Katelyn Jetelina noted on Bluesky, the number of US measles cases this year has already surpassed the total case counts from eight of the previous 15 years. And it is only February.

Texas measles outbreak reaches 90 cases; 9 cases in New Mexico

Other affected counties in Texas include Dawson (6 cases); Ector (1); Lubbock (1); Lynn (1); Terry (20); and Yoakum (4).

In Texas, the majority of the cases continue to be in children: 26 are in infants and young children ages 0 to 4, and 51 are between ages 5 and 17. All but five cases have been in unvaccinated people. Sixteen people (roughly 18 percent) have been hospitalized.

In New Mexico, there have been no hospitalizations, and five of the nine cases are in adults. The other four cases were between the ages of 5 and 17.

Given low vaccination rate in the area and the contagiousness of measles, health officials expect the outbreak to continue to grow. Measles is one of the most infectious viruses known; 90 percent of people who are unvaccinated and exposed will fall ill. The disease is marked by high fevers and a telltale rash and can cause severe complications in some, including younger children.

In the US, about 20 percent of people with measles are typically hospitalized. Five percent develop pneumonia, and up to 3 in 1,000 die of the infection. In rare cases, measles can cause a fatal disease of the central nervous system later in life called Subacute sclerosing panencephalitis. Measles also wipes out immune responses to other infections (a phenomenon known as immune amnesia), making people vulnerable to various illnesses.

Louisiana officially ends mass vaccinations as RFK Jr. comes to power

“Rather than instructing individuals to receive any and all vaccines, LDH staff should communicate data regarding the reduced risk of disease, hospitalization, and death associated with a vaccine and encourage individuals to discuss considerations for vaccination with their healthcare provider,” he wrote.

“Ripped in half”

Susan Hassig, an infectious disease epidemiologist and professor emerita at Tulane University’s School of Public Health, told the Times-Picayune that this is problematic advice. Many people don’t have primary care providers. “They go to an urgent care or a clinic,” Hassig said. “In Louisiana, they go to the emergency room.”

The memo lands amid widespread fear that Kennedy’s appointment will lead to further erosion of America’s trust in vaccination and its vaccination rates. Already, rates of routine childhood vaccination in kindergartners across the nation have slipped into the range of 92 percent, woefully below the 95 percent threshold to prevent onward disease spread. Exemptions from school vaccination requirements are at an all-time high.

Further, the country is also in the midst of the worst flu season in 15 years. The percent of doctor’s visits for influenza-like illnesses (a standard metric for flu season) hit 7.8 percent this week, a high not seen since the 2009–2010 season amid the emergence of the H1N1 swine flu. The Centers for Disease Control and Prevention estimates that there have been at least 29 million illnesses, 370,000 hospitalizations, and 16,000 deaths from flu so far this season. This week, 11 children died of flu, bringing the 2024–2025 pediatric death toll to 68.

Among the recent deaths was a healthy 9-year-old girl in North Carolina, who died from flu complications on January 29. “I literally feel like my heart has been ripped in half,” her mother told WRAL News.

Seasonal flu shots significantly reduce the risk of death, particularly in children.

“A sicker America”: Senate confirms Robert F. Kennedy Jr. as health secretary

anti-vaccine, Confirmation, conspiracy theories, Department of Health and Human Services, health, Health Secretary, infectious diseases, robert f kennedy jr, Senate, Trump, vaccination / DJ Henderson / February 14, 2025

The US Senate on Thursday confirmed the long-time anti-vaccine advocate Robert F. Kennedy Jr. as Secretary of Health and Human Services.

The vote was largely along party lines, with a tally of 52 to 48. Sen. Mitch McConnell (R–Ky.), a polio survivor and steadfast supporter of vaccines, voted against the confirmation, the only Republican to do so.

Before the vote, Minority Leader Charles Schumer (D–N.Y.) claimed that if there had been a secret ballot today, most Republicans would have voted against Kennedy. “But sadly, and unfortunately for America, Republicans are being strong-armed by Donald Trump and will end up holding their nose and voting to confirm Mr. Kennedy… What a travesty,” Schumer said.

Senator Mike Crapo (R–Idaho) shot back, supporting Kennedy’s nomination and chastising his colleagues for their continued “attacks” on Kennedy. “He has made it very clear that he will support safe vaccinations and just wants to see that the research on them is done and done well,” Crapo said, seemingly not acknowledging the vast wealth of high-quality research that has already been done on vaccine safety and efficacy.

As the top health official for the Trump administration, Kennedy says he will focus on improving nutrition and reducing chronic diseases, in part by cracking down on food additives, processed foods, and the influence of food and drug makers on federal agencies. Prior to his confirmation, he campaigned on the slogan “Make America Healthy Again,” aka MAHA, which he has moved to trademark.

Anti-vaccine advocacy

While his stated goals have drawn support and praise from some lawmakers and health advocates, his confirmation has been highly controversial because he is one of the most prominent and influential anti-vaccine advocates in the country. He has worked for decades to erode trust in safe, life-saving vaccinations as the head of the anti-vaccine organization he founded, Children’s Health Defense, and spread misinformation and conspiracy theories. Upon seeking the confirmation, he transferred his trademark application to an LLC managed by Del Bigtree, another prominent anti-vaccine advocate who has spread conspiracy theories.

Nine unvaccinated people hospitalized as Texas measles outbreak doubles

In an interview with Ars Technica last week, Zach Holbrooks, the executive director of the South Plains Public Health District (SPPHD), which includes Gaines, said that the area has a large religious community that has expressed vaccine hesitancy.

Additional cases likely

Pockets of the county have yet lower vaccination rates than the county-wide averages suggest. For instance, one independent public school district in Loop, in the northeast corner of Gaines, had a vaccination rate of 46 percent in the 2023–2024 school year.

Measles is one of the most infectious diseases known. The measles virus spreads through the air and can linger in the airspace of a room for up to two hours after an infected person has left. Ninety percent of unvaccinated people who are exposed will fall ill with the disease, which is marked by a very high fever and a telltale rash. Typically, 1 in 5 unvaccinated people with measles in the US end up hospitalized, and 1 in 20 develop pneumonia. Between 1 to 3 in 1,000 die of the infection. In rare cases, it can cause a fatal disease of the central nervous system called Subacute sclerosing panencephalitis later in life. Measles can also wipe out immune responses to other infections (a phenomenon known as immune amnesia), making people vulnerable to other infectious diseases.

“Due to the highly contagious nature of this disease, additional cases are likely to occur in Gaines County and the surrounding communities,” the state health department said.

While Gaines is remarkable for its low vaccination rate, vaccination coverage nationwide has slipped in recent years as vaccine misinformation and hesitancy have taken root. Overall, vaccination rates among US kindergartners have fallen from 95 percent in the 2019–2020 school year into the 92 percent range in the 2023–2024 school year. Vaccine exemptions, meanwhile, have hit an all-time high. Health experts expect to see more vaccine-preventable outbreaks, like the one in Gaines, as the trend continues.

Flu surges in Louisiana as health department barred from promoting flu shots

The statement seemed to offer an assurance that other vaccines were not subject to the new restrictions. “Changes regarding seasonal vaccines like COVID and influenza do not change the Department’s policy or messaging regarding childhood immunizations,” it read.

This flu season, the health department has reportedly canceled standard vaccination events and clinics. On social media, the department has avoided mentioning flu shots in posts about the flu, instead advising people to wash their hands and cover their coughs.

While Louisiana is seeing an early surge in influenza, the rest of the country is on an upward trend in what appears to be a normal-looking season so far. Nationally, the percentage of doctor visits that were for ILIs is 3.8 percent, with the upswing in ILI activity similar to what was seen in the 2019–2020 flu season at this point in the year. At the peak of flu seasons, the percentage of visits for ILIs usually tops out around 7 percent to 8 percent.

Two children died last week of flu, bringing the season’s total pediatric deaths to four. In the 2023–2024 season, 206 children died with influenza-associated disease. Most of the deaths occurred in early 2024.

COVID-19 is also ramping up a winter wave. While standard disease burden indicators—hospitalization and deaths—are low, they’re trending positive. Wastewater surveillance, meanwhile, is showing a steep incline, with levels of the virus being detected at “moderate” levels.

Record measles outbreak in Oregon blamed on vaccine exemptions

consequences —

Vaccine exemptions at nearly 9% in the state, enabling sustained transmission.

Beth Mole – Sep 4, 2024 7: 10 pm UTC

Enlarge / A US child infected with measles during a 2024 outbreak. The child’s cheek shows the characteristic rash associated with this viral infection.

With one of the highest vaccine exemption rates in the country, Oregon is experiencing its largest measles outbreak in decades. This year’s count is now higher than anything seen since 2000, when the Centers for Disease Control and Prevention declared the highly contagious virus eliminated from the US.

Since the start of the year, Oregon has tallied 31 cases of measles, all in unvaccinated people. The cases have been accumulating in sustained waves of transmission since mid-June.

Last month, when the outbreak tally was still in the 20s, health officials noted that it was nearing a state record set in 2019. There were 28 cases that year, which were linked to a large outbreak across the border in Washington state. But, with that record now surpassed, the state is in pre-elimination territory.

“Before 2019, you have to go all the way back to the early 1990s to see case counts this high,” Paul Cieslak, medical director for communicable diseases and immunization at Oregon Health Authority, said in a statement. “The reason is, we maintained very high vaccination rates and very high population levels of immunity. Unfortunately, we’ve seen an erosion in the percentage of people who are getting vaccinated against measles.”

Vaccination decline

In 2000, when measles was declared officially eliminated, only about 1 percent of kindergarteners in the state had exemptions from childhood vaccines, such as measles. But in the years since, Oregon has become one of the states with the highest exemption rates in the country. In the 2022–2023 school year, 8.2 percent of Oregon kindergarteners had exemptions from vaccinations, according to a CDC analysis published in November. Only Idaho had a higher rate, with 12.1 percent of kindergarteners exempt. Utah was a close third, with 8.1 percent, followed by Arizona (7.4 percent) and Wisconsin (7.2 percent).

Oregon’s exemption rate has risen since then, with the exemption rate now at 8.8 percent, according to the Oregon Health Authority. Any exemption rate above 5 percent is concerning. At that threshold, even if every non-exempt child is vaccinated, a state will not be able to achieve the target of 95 percent vaccine coverage expected to prevent sustained transmission of infectious diseases.

Health officials are directly linking the rise of non-medical exemptions to the current measles outbreak, which is centered in Clackamas, Marion, and Multnomah counties. All three are in the northwestern corner of the state, with Clackamas and Multnomah in the Portland area.

“In Clackamas County, as in other Oregon counties, pockets of unvaccinated people raise risk of infection in communities where they live,” Clackamas County Health Officer Sarah Present said. “That’s why the counties reach out to every case that’s been identified and try to determine exactly where they’ve been while infectious.”

Notorious virus

Measles is among the most infectious viruses known. It is notorious for its ability to stay aloft in indoor air for up to two hours after an infected person has been present. For unvaccinated people who are exposed, up to 9 out of 10 will end up falling ill. Those who become infected are contagious from about four days before developing the tell-tale rash and four days after it erupts. Other common symptoms of the infection include high fever, runny nose, cough, and conjunctivitis (pink eye). Many children become severely ill, requiring hospitalization.

In a small percentage of cases, measles can lead to severe complications, including pneumonia, encephalitis, and a progressive neurological disorder (subacute sclerosing panencephalitis), which develops five to 10 years after an initial infection. Additionally, measles is known to cause “immune amnesia.” That is, being infected with measles virus wipes out existing antibodies and immune responses to other germs, leaving people more vulnerable to other diseases.

Two doses of MMR vaccine (measles, mumps, and rubella) are 97 percent effective against measles, and that protection is considered life-long.

So far this year, the US has logged 236 measles cases. Of those, 40 percent were in children under the age of 5, while 30 percent were in children and teens between the ages 5 and 19. Eighty-seven percent were either unvaccinated or had an unknown vaccination status. Forty-four percent (103 of 236) were hospitalized.

While Oregon’s current outbreak has broken its state records, the largest outbreak this year was in Illinois, where a total of 67 cases were reported amid spread at a Chicago-area migrant shelter.

This year’s tally is already well ahead of the total for 2023, which reached just 59 cases. It is still significantly lower than the 1,274 cases seen in 2019, when the US nearly lost its elimination status.

Health experts plead for unvaxxed Americans to get measles shot as cases rise

MMR is safe and effective —

The US hit last year’s total in under 12 weeks, suggesting we’re in for a bad time.

Beth Mole – Mar 19, 2024 4: 12 pm UTC

Enlarge / A view from a hospital as children receiving medical treatment, in capital Kabul, Afghanistan on April 18, 2022. More than 130 children have died from the measles in Afghanistan since the beginning of this year.

The Centers for Disease Control and Prevention and the American Medical Association sent out separate but similar pleas on Monday for unvaccinated Americans to get vaccinated against the extremely contagious measles virus as vaccination rates have slipped, cases are rising globally and nationally, and the spring-break travel period is beginning.

In the first 12 weeks of 2024, US measles cases have already matched and likely exceeded the case total for all of 2023. According to the CDC, there were 58 measles cases reported from 17 states as of March 14. But media tallies indicate there have been more cases since then, with at least 60 cases now in total, according to CBS News. In 2023, there were 58 cases in 20 states.

“As evident from the confirmed measles cases reported in 17 states so far this year, when individuals are not immunized as a matter of personal preference or misinformation, they put themselves and others at risk of disease—including children too young to be vaccinated, cancer patients, and other immunocompromised people,” AMA President Jesse Ehrenfeld said in a statement urging vaccination Monday.

The latest data indicates that vaccination rates among US kindergarteners have slipped to 93 percent nationally, below the 95 percent target to prevent the spread of the disease. And vaccine exemptions for non-medical reasons have reached an all-time high.

The CDC released a health advisory on Monday also urging measles vaccination. The CDC drove home the point that unvaccinated Americans are largely responsible for importing the virus, and pockets of unvaccinated children in local communities spread it once it’s here. The 58 measles infections that have been reported to the agency so far include cases from seven outbreaks in seven states. Most of the cases are in vaccine-eligible children aged 12 months and older who are unvaccinated. Of the 58 cases, 54 (93 percent) are linked to international travel, and most measles importations are by unvaccinated US residents who travel abroad and bring measles home with them, the CDC flagged.

The situation is likely to worsen as Americans begin spring travel, the CDC suggested. “Many countries, including travel destinations such as Austria, the Philippines, Romania, and the United Kingdom, are experiencing measles outbreaks,” the CDC said. “To prevent measles infection and reduce the risk of community transmission from importation, all US residents traveling internationally, regardless of destination, should be current on their [measles-mumps-rubella (MMR)] vaccinations.” The agency added in a recommendation to parents that “even if not traveling, ensure that children receive all recommended doses of MMR vaccine. Two doses of MMR vaccine provide better protection (97 percent) against measles than one dose (93 percent). Getting MMR vaccine is much safer than getting measles, mumps, or rubella.”

For Americans who are already vaccinated and communities with high vaccination coverage, the risk is low, the CDC noted. “However, pockets of low coverage leave some communities at higher risk for outbreaks.” This, in turn, threatens wider, continuous spread that could overturn the country’s status of having eliminated measles, which was declared in 2000. The US was close to losing its elimination status in 2019 when outbreaks among unvaccinated children drove 1,247 cases across 31 states. Vaccination rates have only fallen since then.

“The reduction in measles vaccination threatens to erase many years of progress as this previously eliminated vaccine-preventable disease returns,” the AMA’s Ehrenfeld warned.

As Ars has reported previously, measles is among the most contagious viruses known and can linger in airspace for up to two hours. Up to 90 percent of unvaccinated people exposed will contract it. Symptoms can include high fever, runny nose, red and watery eyes, and a cough, as well as the hallmark rash. About 1 in 5 unvaccinated people with measles are hospitalized, while 1 in 20 infected children develop pneumonia, and up to 3 in 1,000 children die of the infection. Brain swelling (encephalitis) can occur in 1 in 1,000 children, which can lead to hearing loss and intellectual disabilities. The virus can also destroy immune responses to previous infections—a phenomenon known as “immune amnesia”—which can leave children vulnerable to various other infections for years afterward.
