U.S. official backs off promise to solve cause of autism by September
By Issam AHMED
A top U.S. science official has backed away from a bold promise made by Health Secretary Robert F Kennedy Jr to reveal the cause of autism by September.
Jay Bhattacharya, director of the National Institutes of Health, told reporters the timeline referred not to a discovery, but to the launch of a new research initiative -- with no firm deadline for results.
"We're hoping that by September, we'll have the call for proposals out, and we'll have a competition among scientists across the country using a normal NIH process for selecting the proposals that win and get an award," he said.
Kennedy, a vaccine skeptic, has long promoted a debunked theory linking childhood vaccines to autism, and recently appointed an anti-vaccine activist who holds the same views to be a data analyst -- a move critics say guarantees bias.
Bhattacharya, however, said the study itself would conform to rigorous standards and would be evaluated through the normal NIH peer review process.
He said the timeline for results was "hard to predict" but that his team was "cutting red tape" to remove any bureaucratic obstacles.
"I would like to have a timeline within a year, where they start to put out the preliminary results or the results -- we'll see," Bhattacharya said.
Bhattacharya also confirmed a report by CBS News that the NIH was gathering private medical records from a number of federal and commercial databases to give the study statistical power, but insisted all the data would be anonymized.
During his own Senate confirmation hearings, Bhattacharya, a physician-scientist and health economist known for opposing lockdowns during the Covid-19 pandemic, stated he does not "generally believe" there's a link between vaccines and autism.
The estimated prevalence of autism in children aged eight rose to one in 31 in 2022, according to a study published last week by the Centers for Disease Control and Prevention, compared to one child in 150 in 2000 -- a trend the authors attributed to improved diagnosis methods.
Autism is a complex neurodevelopmental condition that affects behavior, communication, learning, and social interaction. There is no single known cause, but a combination of genetic and environmental factors is likely involved, according to the World Health Organization.
Over the past two decades, milder forms and related conditions have increasingly been grouped under the broader category of autism spectrum disorder, or ASD.

Who's in charge? CDC's leadership 'crisis' apparent amid new COVID-19 vaccine guidance
This image from video provided by the Department of Health and Human Services shows Health and Human Services Secretary Robert F. Kennedy Jr. speaking alongside Food and Drug Administration administrator Dr. Martin Makary, left, and Dr. Jay Bhattacharya, director of the National Institutes of Health, as they announce that the government would no longer endorse the COVID-19 vaccine for healthy children or pregnant women. (Health and Human Services via AP) By AMANDA SEITZ and MIKE STOBBE There was a notable absence last week when U.S. Health and Human Services Secretary Robert F Kennedy Jr announced in a 58-second video that the government would no longer endorse the COVID-19 vaccine for healthy children or pregnant women. The director of the Centers for Disease Control and Prevention — the person who typically signs off on federal vaccine recommendations — was nowhere to be seen. The CDC, a $9.2 billion-a-year agency tasked with reviewing life-saving vaccines, monitoring diseases and watching for budding threats to Americans' health, is without a clear leader. 'I've been disappointed that we haven't had an aggressive director since — February, March, April, May — fighting for the resources that CDC needs,' said Dr. Robert Redfield, who served as CDC director under the first Trump administration and supported Kennedy's nomination as the nation's health secretary. The leadership vacuum at a foremost federal public health agency has existed for months, after President Donald Trump suddenly withdrew his first pick for CDC director in March. A hearing for his new nominee — the agency's former acting director Susan Monarez — has not been scheduled because she has not submitted all the paperwork necessary to proceed, according to a spokesman for Sen. Bill Cassidy, R-La., who will oversee the nomination. HHS did not answer written questions about Monarez's nomination, her current role at the CDC or her salary. An employee directory lists Monarez, a longtime government employee, as a staffer for the NIH under the Advanced Research Projects Agency for Health. Redfield described Kennedy as 'very supportive' of Monarez's nomination. Instead, a lawyer and political appointee with no medical experience is 'carrying out some of the duties' of director at the agency that for seven decades has been led by someone with a medical degree. Matthew Buzzelli, who is also the chief of staff at the CDC, is 'surrounded by highly qualified medical professionals and advisors to help fulfill these duties as appropriate,' Andrew Nixon, an HHS spokesperson said in a statement. Adding to the confusion was an employee-wide email sent last week that thanked 'new acting directors who have stepped up to the plate." The email, signed by Monarez, listed her as the acting director. It was was sent just days after Kennedy said at a Senate hearing that Monarez had been replaced by Buzzelli. The lack of a confirmed director will be a problem if a public health emergency such as the COVID-19 pandemic or a rapid uptick in measles cases hits, said Michael Osterholm, an epidemiologist at the University of Minnesota. 'CDC is a crisis, waiting for a crisis to happen,' said Osterholm. 'At this point, I couldn't tell you for the life of me who was going to pull what trigger in a crisis situation." At CDC headquarters in Atlanta, employees say Monarez was rarely heard from between late January – when she was appointed acting director – and late March, when Trump nominated her. She also has not held any of the 'all hands' meetings that were customary under previous CDC chiefs, according to several staffers. One employee, who insisted on anonymity because they were not authorized to speak to the media and fears being fired if identified said Monarez has been almost invisible since her nomination, adding that her absence has been cited by other leaders as an excuse for delaying action. The situation already has led to confusion. In April, a 15-member CDC advisory panel of outside experts met to discuss vaccine policy. The panel makes recommendations to the CDC Director, who routinely signs off on them. But it was unclear during the meeting who would be reviewing the panel's recommendations, which included the expansion of RSV vaccinations for adults and a new combination shot as another option to protect teens against meningitis. HHS officials said the recommendations were going to Buzzelli, but then weeks passed with no decision. A month after the meeting ended, the CDC posted on a web site that Kennedy had signed off on recommendations for travelers against chikungunya, a viral disease transmitted to humans by mosquitos. But there continues to be no word about a decision about the other vaccine recommendations. The problem was accentuated again last week, when Kennedy rolled out recommendations for the COVID-19 vaccine saying they were no longer recommended for healthy children or pregnant women, even though expectant mothers are considered a high-risk group if they contract the virus. Kennedy made the surprise announcement without input from the CDC advisory panel that has historically made recommendations on the nation's vaccine schedule. The CDC days later posted revised guidance that said healthy kids and pregnant women may get the shots. Nixon, the HHS spokesman, said CDC staff were consulted on the recommendations, but would not provide staffer's names or titles. He also did not provide the specific data or research that Kennedy reviewed to reach his conclusion on the new COVID-19 recommendations, just weeks after he said that he did not think 'people should be taking medical advice' from him. 'As Secretary Kennedy said, there is a clear lack of data to support the repeat booster strategy in children,' Nixon said in a statement. Research shows that pregnant women are at higher risk of severe illness, mechanical ventilation and death, when they contract COVID-19 infections. During the height of the pandemic, deaths of women during pregnancy or shortly after childbirth soared to their highest level in 50 years. Vaccinations also have been recommended for pregnant women because it passes immunity to newborns who are too young for vaccines and also vulnerable to infections. Nixon did not address a written question about recommendations for pregnant women. Kennedy's decision to bypass the the advisory panel and announce new COVID-19 recommendations on his own prompted a key CDC official who works with the committee – Dr. Lakshmi Panagiotakopoulos – to announce her resignation last Friday. 'My career in public health and vaccinology started with a deep-seated desire to help the most vulnerable members of our population, and that is not something I am able to continue doing in this role,' she wrote in an email seen by an Associated Press reporter. Signs are mounting that the CDC has been 'sidelined' from key decision-making under Kennedy's watch, said Dr. Anand Parekh, the chief medical adviser for The Bipartisan Policy Center. 'It's difficult to ascertain how we will reverse the chronic disease epidemic or be prepared for myriad public health emergencies without a strong CDC and visible, empowered director,' Parekh said. 'It's also worth noting that every community in the country is served by a local or state public health department that depends on the scientific expertise of the CDC and the leadership of the CDC director.' © Copyright 2025 The Associated Press.

Japan's Birth Rate Remains Stubbornly Low Despite Efforts; Expert Recommends Reducing Working Hours, Work-Style Reform
Yomiuri Shimbun file photo The Health, Labor and Welfare Ministry in Chiyoda Ward, Tokyo Despite years of extensive efforts to combat Japan's chronically low birth rate, the latest statistics indicate that there has been little tangible impact. According to the nation's 2024 vital statistics, the number of babies born to Japanese citizens in Japan fell below 700,000 for the first time, and the total fertility rate, or the average number of children a woman is expected to have in her lifetime, slipped to a record low of 1.15. The annual number of babies born had dipped below 800,000 only as recently as 2022, and a sense of panic is spreading among central and local governments as cash handouts, making high school education free and a slew of other policies have failed to reverse these declines. Tokyo Gov. Yuriko Koike wore a grim expression Wednesday after the figures compiled by the Health, Labor and Welfare Ministry were released, but pledged to continue tackling the issue. 'I feel that we need to battle on at this time,' Koike said. 'We'll continue implementing policies.' The Tokyo metropolitan government has declared that efforts to combat the low birth rate are a high-priority issue, and has led the nation in rolling out a string of policies such as free nursery care and giving households with children aged up to 18 a handout of ¥5,000 per month. Despite these steps, the fertility rate for women living in the capital has been below 1 for two consecutive years and sank to 0.96 in 2024. 'We're trying all kinds of policies, but the situation remains severe,' a senior metropolitan government official said. Ishikawa Prefecture's fertility rate recorded a drop of 0.11 percentage points from 2023, the biggest fall among the nation's 47 prefectures. The prefecture has attempted to stem the decline through such measures as promoting businesses that support a balance between work and raising children. 'We'll accept the latest results and use the examples of other local governments as a reference for future policies,' an Ishikawa prefectural government official in charge of child policies said. Tokyo a magnet for young people The Yomiuri Shimbun The number of couples who got married in 2024 increased for the first time in two years. Although about 480,000 couples tied the knot, this figure remains well below the almost 600,000 couples who did so in 2019. The number plunged the following year as the COVID-19 pandemic erupted. The average age at which a woman married for the first time ticked up 0.1 years from 2023. The average age at which women gave birth to their first baby was 31.0, about five years older than 1975's average age of 25.7. The influx of young women to Tokyo and other major urban centers from rural areas has been identified as a major driver of these trends. According to Internal Affairs and Communications Ministry statistics, the fertility rate fell especially sharply in the Tohoku region. A striking number of municipalities in Tohoku recorded that the number of women in their 20s and early 30s who moved away in 2024 eclipsed the number of men in those age brackets who departed. In major cities, many young people said they could not consider getting married because they were too busy with their job or were employed as nonregular workers. 'Rural areas must come up with ways to increase employment opportunities that encourage women to choose to live there,' said Kanako Amano, a senior researcher on demographics at the NLI Research Institute. 'I urge local governments in major cities to concentrate resources on ensuring stable employment that allows young men and women to consider getting married and having children.' Taking kids to the office Amid these gloomy statistics, some companies have produced positive results by changing the way their employees work. People Co., a toy manufacturer based in Chuo Ward, Tokyo, encourages employees to bring their children with them, so they can work while their children play at the office. Nine of People's about 45 employees were raising children in 2019, and that figure has soared to 17 this year. Kyoto University Prof. Haruka Shibata, an expert in sociology, said calculations based on data collated from other nations indicated that expanding child-rearing allowances could nudge up the fertility rate by about 0.1 percentage points. However, reducing the working hours of men in full-time, regular employment by two hours each day could increase the rate by 0.35 percentage points. The Children's Future Strategy approved by the Cabinet in 2023 also stated that reducing long working hours would lead to people having enough time to devote to child-rearing and household chores. 'The government should discuss steps such as reducing legal working hours, and beef up national policies that could change the way people work,' Shibata said.
