(MASSACHUSETTS) — A Massachusetts judge ruled on Monday in favor of medical organizations in their litigation against Health and Human Services Secretary Robert F. Kennedy Jr. over his changes to federal vaccine policy.
The judge temporarily blocked changes to the childhood vaccine schedule that were made at the beginning of this year, in which Kennedy reduced the number of recommended shots from 17 to 11.
The judge also suspended the appointments of the 13 members of the Centers for Disease Control and Prevention’s vaccine advisory committee, who were all appointed unilaterally by Kennedy after he fired all the preceding members.

(NEW YORK) — Health experts tell ABC News that the current science behind the hantavirus that circulated throughout the MV Hondius does not show the same levels of transmission as with COVID-19, while acknowledging that the scenario may seem similar to the beginning of the 2020 pandemic.
“Our current understanding is that person-to-person transmission of Andes virus is relatively rare and generally associated with prolonged close contact,” the current Centers for Disease Control and Prevention public health assessment said. “There is also no documented evidence of presymptomatic transmission.”
Officials around the globe have taken major steps to prevent the spread of the hantavirus, and an American doctor who was onboard noted how conditions on the cruise ship may have helped the virus propagate.
In the U.S., the boat’s 18 American passengers have been put in quarantine in Nebraska, while more than 40 people with exposure to the sick are being monitored to see if they develop the illness.
“In the vast majority of cases it happens when people breathe in mouse secretions,” Dr. Emily Abdoler, a clinical associate professor of medicine at the University of Michigan, who specializes in infectious diseases, told ABC News.
“The Andes strain found in Chile and Argentina has the possibility of human-to-human transmission, but that’s really more really close contact. It’s not sharing the same household,” she added. “It’s more like sharing the same bed.”
Dr. Stephen Kornfeld, an American oncologist who became the ship’s de facto doctor after the Hondius’ physician contracted the virus, initially received inconclusive results with samples taken from the ship but later tested negative.
Speaking to ABC News from his quarantine on Thursday, Kornfeld noted that conditions on the ship — including ventilation and the size of rooms — could have created a “complicated” situation for transmission while observing some social casual contact.
“If you do have casual contact, you’re doing it repetitively,” he said. “There were three rooms that we would gather in many times a day, often for an hour or an hour and a half, for lectures and discussions and meals. And I can just envision lots of frequent casual contacts, and perhaps over time that adds up to something more than just a single casual contact.”
Abdoler, who helped diagnose a case of hantavirus in Michigan in 2021 — the type we have in the U.S. that does not spread between people –said the benefit that medical professionals and agencies, such as the World Health Organization, have now is that the hantavirus has been researched for over 30 years. It is not a new virus.
While the data around the Andes strain believed to have been on the boat is still limited given the rare number of cases outside of South America, Abdoler said there does not appear to be any indication that the transmission methods have changed for the Andes strain.
ABC News medical contributor and epidemiologist Dr. John Brownstein concurred, saying that previous research suggests the hantavirus is a respiratory illness. That means germs can be coughed up, he noted, but it is not an aerosol-based virus.
“It’s not like COVID or measles where it could linger in the air for some time,” he said.
Brownstein added that the incubation period for the virus is long, and despite the lower risk for person-to-person transmission, it is critical that health officials stick to their policies to isolate and monitor anyone connected to the Hondius. Isolation can then be initiated if they become a positive case.
“Incubation can be anywhere from one to eight weeks,” he noted.
During a news briefing Friday, WHO officials stressed that said there is no evidence so far that the virus has changed to become more transmissible or more severe.
Officials said transmission is believed to be based on several factors, including how infectious the patient is, the environment and whether protection and PPE was used.
On Friday, acting Centers for Disease Control and Prevention director Jay Bhattacharya told reporters no cases of hantavirus have been reported in the U.S.
There are now at least 10 cases that have been linked to the ship’s outbreak. Two passengers died from the virus and a third death has been deemed probable by WHO.
Sixteen Hondius passengers, including Kornfeld, initially were flown to the quarantine center at the University of Nebraska Medical Center and had not shown any symptoms as of early Friday. Kornfeld had been placed in a biocontainment unit at the facility.
Two other American passengers were flown to Atlanta for “assessment and care,” according to officials. They were later transferred to the quarantine unit in Nebraska on Friday.
The remainder of the passengers are in quarantine at home and are being monitored.
WHO warned more positive cases could still appear during quarantine because the virus’ incubation period is long, but said that would not necessarily mean the outbreak is growing.
Abdoler noted that the fact that there have not been as many positive cases from the ship and their contacts shows that the data about the Andes transmission is holding up and there are no signs that the virus can spread as easily as other pathogens.
She noted that he is glad that the risk is being taken seriously and that those that have been exposed are being monitored.
“My sense is that there is no really need to panic, but [WHO] is taking a very conservative approach to the outbreak and asking everyone to isolate during the intubation period,” she said.
“I think it is good they are taking a conservative approach because there are unknowns, but I am not personally altering my personal practices of travel or how I go out,” she added.

(LONDON) — An epidemiologist from the World Health Organization (WHO) said Thursday that the suspected hantavirus cluster aboard a cruise ship is not the beginning of another COVID-19 pandemic.
Eight cases are currently being reported by the WHO, including five laboratory-confirmed cases and three suspected cases. Of those eight cases, three have died.
Dr. Maria Van Kerkhove, an infectious disease epidemiologist and acting director of epidemic and pandemic management at the WHO, was asked during a press conference what the difference was between this cluster and the early days of the COVID pandemic.
“I want to be unequivocal here. This is not SARS-CoV-2. This is not the start of a COVID pandemic. This is an outbreak that we see on a ship,” Van Kerkhove said.
Van Kerkhove explained that hantavirus doesn’t spread in the same way that coronaviruses do, but rather through “close, intimate contact.” Most hantaviruses don’t transmit from person to person.
“The actions that are being taken on board [the ship] are precautionary to prevent any onward spread,” she added.
There appears to be one confirmed case and two suspected cases that have not been added to the WHO’s official count yet.
Officials told ABC News a female individual, who was on a KLM flight with the Dutch female patient who later died, developed symptoms and was admitted to a hospital. Leiden University Medical Centre in the Netherlands confirmed on Thursday that the female patient has hantavirus and is receiving care.
Additionally, two Singapore residents who were on board the ship are currently being monitored. Singapore’s Communicable Diseases Agency said it was notified of the individuals on May 4 and May 5.
“They have been isolated at the National Centre for Infectious Diseases, where they are being tested for hantavirus. The risk to the general public in Singapore is currently low,” the agency said.
The agency added that test results are pending, with one resident having a runny nose and the other is asymptomatic.
Three deaths have been recorded so far, including a married Dutch couple. The 70-year-old male patient died on April 11, and his body was taken off the ship on the island of St. Helena on April 24. His 69-year-old wife disembarked on the same day, and her health rapidly deteriorated. She died at an emergency department in South Africa on April 26.
A third passenger, a German woman, presented with pneumonia symptoms starting on April 28, according to the WHO. The woman died on May 2 from causes not yet known, according to Oceanwide Expeditions, which operates the cruise ship.
The WHO said 29 people disembarked on St. Helena on the same day that the body of the Dutch male patient and his wife disembarked.
They traveled to 12 countries: Canada, Switzerland, Germany, Denmark, Great Britain, St. Kitts and Nevis, Netherlands, New Zealand, Singapore, Sweden, Turkey and the United States.
The disembarked guests have all been contacted by Oceanwide Expeditions. In the U.S., local authorities in three states — Arizona, Georgia and California — are monitoring the disembarked passengers and are conducting contact tracing, None have shown signs of illness at this time.
Anais Legend, technical lead for viral hemorrhagic fevers at WHO, said during the press conference on Thursday that “step-by-step guidance is being developed” for the disembarked passengers and that the WHO is coordinating with national authorities.
Anyone with any signs of symptoms will be isolated while other passengers have their risk exposure evaluated.
Public health experts said they expected a more robust response from the Centers for Disease Control and Prevention (DC) and the National Institutes of Health.
“The CDC would typically be asked by WHO or by a country to help in technical assistance,” Dr. Carlos del Rio, an H. Cliff Sauls distinguished professor of medicine at the Emory University School of Medicine, told reporters on Thursday.
Typically, CDC teams would be deployed to an area, he said, and the teams would perform contact tracing and interviews and conduct an outbreak investigation.
“I would envision by now, many, many days ago, we would have seen a team from CDC deployed to the area,” he added.
Dr. Jeanna Marrazzo, CEO of the IDSA, added that she would have expected a CDC press briefing, an alert from the agency’s Health Alert Network or information from the NIH on potential treatments in the pipeline that could receive emergency use authorization to help treat hantavirus patients.
Marrazzo said she is not aware that conservations about potential therpaies at NIH aren’t happening but that it “doesn’t give me a lot of assurance or reassurance that we are not hearing any of that.”
The WHO said during Thursday’s press briefing that the U.S. is coordinating with the global health agency in a technical capacity.
Because the cluster is limited and confined to a cruise ship, the “idea of sending messages across the world and panicking everyone is not required,” said Dr. Abdirahman Mahmoud, director of the WHO’s health emergency alert and response operations.
He added that the WHO is “informally” aware that contact tracing has been done of the U.S. passengers who disembarked last month and are back home.

(NEW YORK) — An emergency rule from the Florida Department of Health went into effect on Sunday that could restrict tens of thousands of people from accessing HIV medication.
The state issued cuts to the AIDS Drug Assistance Program (ADAP), a federal-state partnership that provides free FDA-approved HIV medication for low-income, uninsured or underinsured people.
Under the emergency rule, eligibility for ADAP was lowered to include those at or below 130% of the federal poverty level, which equals about $20,345 per year for a one-person household, according to the Department of Health and Human Services.
Previous eligibility was at or below 400% of the poverty level, which equals about $62,600 per year for a one-person household, according to HHS.
Additionally, the emergency rule limits insurance coverage of Biktarvy, a once-daily pill to treat HIV and used by about 60% of those enrolled in ADAP.
HIV advocates estimate that as many as 16,000 of the 30,000 Floridians enrolled in ADAP could be at risk of restricted access.
“These cuts will impact communities throughout the state, will threaten the lives of people with HIV and will lead to spikes in new HIV diagnoses and a rise in health care costs as people with HIV develop serious infections requiring hospitalization,” said Dr. Anna K. Person, chair of the HIV Medicine Association, a community of health care professionals that works toward advancing the response of the HIV epidemic, in a statement.
“HIV treatment disruptions of this magnitude will result in a public health disaster. Florida must follow due process and work with health care professionals, people with HIV and the state legislature to address any funding challenges,” the statement continued.
The new emergency rule is only in effect for 90 days and cannot be renewed unless a rule is proposed to implement the changes through formal administrative rulemaking.
Health officials have cited the “rising health care insurance premiums nationwide” and lack of federal funding as reason for the cuts. Officials said the adjustments will prevent a shortfall of more than $120 million for the state.
The Florida Department of Health did not immediately return ABC News’ request for comment.
