📍 THE 17 FIRED MEMBERS OF CDC’s VACCINE ADVISORY COMMITTEE (ACIP) speak out…

📍“As former ACIP members, we are deeply concerned that these destabilizing decisions, made without clear rationale, may roll back the achievements of US immunization policy, impact people’s access to lifesaving vaccines, and ultimately put US families at risk of dangerous and preventable illnesses.” 🔥

Full text:

Vaccines are one of the greatest global public health achievements. Vaccine recommendations have been critical to the global eradication of smallpox and the elimination of polio, measles, rubella, and congenital rubella syndrome in the US. They have also dramatically decreased cases of hepatitis, meningitis, mumps, pertussis (whooping cough), pneumonia, tetanus, and varicella (chickenpox), and prevented cancers caused by hepatitis B virus and human papillomaviruses.1 Recent scientific advancements enabled the accelerated development, production, and evaluation of COVID-19 vaccines, leveraging novel technologies that are estimated to have prevented approximately 1.6 million hospitalizations and 235 000 deaths in the US alone.2
For more than 60 years, the Advisory Committee on Immunization Practices (ACIP)—codified in the federal regulations (42 USC 217a: advisory councils or committees)—has served as a panel of experts that reviews the most up-to-date evidence on vaccines and monoclonal antibodies (eg, against respiratory syncytial virus [RSV]), providing sound recommendations to the US Centers for Disease Control and Prevention (CDC) regarding how vaccines should be used. ACIP recommendations are the cornerstone of the immunization program in this country. First, they serve as guidance and are the national standard for the use of Food and Drug Administration (FDA) authorized and licensed vaccines, providing a unified and trusted approach to vaccinations for the diverse array of immunization providers across the US. Second, they ensure science-based and tested immunization schedules that are optimized for well-timed protection against serious diseases. Third, the recommendations affect insurance coverage and safeguard broad access for vaccines. Fourth, ACIP’s continued monitoring of disease epidemiology and scrutiny of vaccine safety inform timely updates to recommendations that have maintained the trust and protection of the population. This transparent and ongoing surveillance of vaccines is one of the most stringent around the world, historically making the deliberations and decisions of this committee a beacon for immunization programs globally, while also serving as the foundation for recommendations harmonized with leading medical organizations in the US.3,4
ACIP committee members have always been selected through a rigorous process based on their expertise in immunology, epidemiology, pediatrics, obstetrics, internal and family medicine, geriatrics, infectious diseases, and public health. Historically, committee members were chosen because they worked at hospitals, clinics, health departments, universities, and other organizations where they dedicated themselves to caring for patients, conducting research, and helping to prevent and treat infectious diseases. Members’ deep understanding of immunization issues ensured that vaccine policies were grounded in scientific evidence, aligned with the needs of economically, socially, and medically diverse US communities, and always considered the public value, trust, and acceptability of vaccines.
Despite recent suggestions to the contrary, health care providers and the US public trust ACIP. For the past 18 years, the National Immunization Survey has shown that 99 of every 100 children in the US have received at least some recommended vaccines by 2 years of age, consistent with acceptance of ACIP recommendations implemented by trusted clinicians (National Immunization Survey - Childof Healthy People 2030).…Image 2) Full text part 2:

This does not suggest the population is so distrustful that it warrants dismantling the process by which vaccines have been recommended. ACIP standard procedures have minimized the risk of alleged conflicts of interest and biases. For decades, members of ACIP have undergone a thorough application and review process to participate. Proposed members submitted letters of support from other known experts and peers, completed an interview process, underwent a background check, and disclosed financial interests that might be considered a conflict, including any professional or financial relationships of immediate family members. Historically, it has taken up to 2 years for nominees to be approved to join ACIP.
Once part of the committee, ACIP members spent significant time preparing for meetings, reviewing the scientific evidence, and chairing work groups that, along with many CDC public health officials, led to the final recommendations that were determined during public meetings, which also included opportunities for public comment. Recordings of these meetings, agendas, and presentations were publicly available. Additionally, members agreed to ongoing monitoring and disclosure throughout their tenure. For example, potential conflicts of interest were reviewed throughout their time on the committee. Statements about potential conflicts were required during each meeting and before each vote, and members recused themselves from voting if any conflicts were identified. These disclosures have also recently been posted on the CDC website for public scrutiny. ACIP was among the most stringent and transparent of the federal committees, and we hope those criteria will apply to any new members joining the committee.
The abrupt dismissal of the entire membership of the ACIP, along with its executive secretary, on June 9, 2025, the appointment of 8 new ACIP members just 2 days later, and the recent reduction of CDC staff dedicated to immunizations have left the US vaccine program critically weakened.5,6 These actions have stripped the program of the institutional knowledge and continuity that have been essential to its success over decades. Notably, the ACIP charter specifies that committee members serve overlapping terms to ensure continuity and avoid precisely the disruption that will now ensue. The termination of all members and its leadership in a single action undermines the committee’s capacity to operate effectively and efficiently, aside from raising questions about competence.
Compounding these concerns, recent changes to COVID-19 vaccine policy, made directly by the HHS secretary and released on social media, appear to have bypassed the standard, transparent, and evidence-based review process.7 Such actions reflect a troubling disregard for the scientific integrity that has historically guided US immunization strategy. The newly stated strategy to replace ACIP members with individuals who will “exercise independent judgment, refuse to serve as a rubber stamp, and foster a culture of critical inquiry” is already leading to warnings by academic and scientific institutions, professional organizations, and the public who for decades have known well that these sought-after qualities precisely characterized the now-dismissed members of the ACIP.5

⚠️Tariffs On Medications Will Make America Sick

We might soon see the Trump WH impose tariffs on pharmaceuticals—patients will suffer and die.

During the past few weeks, President Trump’s on-again, off-again tariff wars have rattled the stock market, decimated many Americans’ retirement funds, and promised to send grocery prices soaring—and his administration hasn’t even gotten to critical pharmaceutical tariffs yet. But that will likely be the next shoe to drop.
Trump exempted pharmaceuticals from his first round of tariffs in early April, but recently declared that he intends to impose “a major tariff” on imported medicines “very shortly.” These tariffs, he claims, will prompt pharmaceutical companies to leave countries including China and India and begin “opening up their plants all over the place.”
Commerce Secretary Howard Lutnick said in a television interview in mid-April that these tariffs are coming in the “next month or two.”

What will this mean? 

Read on:

SICKENING—Trump’s DHS just deported a surgeon from Brown University Medical School—who is here legally on an H1B visa that doesn’t expire until 2027, and has committed no crimes. Trained in the U.S. at Ohio State, University of Washington, and Yale as a **transplant surgeon** (one of the most difficult surgical fields in all of medicine!!!), she is a highly trained doctor on kidney transplants, which cannot be easily replaced. Her phone was seized at the border. A federal judge handed down an injunction against her deportation—but she was already deported on a plane en route to Paris. Brown’s kidney transplant clinic is now strained by her deportation.Image

PROVIDENCE — A Rhode Island doctor who had traveled to Lebanon to see her parents was prevented from re-entering the United States at Boston’s Logan International Airport on Thursday evening, her lawyer and a colleague said.

Dr. Rasha Alawieh, 34, who lives in Providence, has been working at Brown Medicine’s Division of Kidney Disease & Hypertension since last July, and she [has] been part of the transplant service at Rhode Island Hospital, according to Dr. George Bayliss, the organ transplant division’s medical director. She has been studying and working in the United States for about six years, he said Friday.

The US consulate in Lebanon had issued her an H-1B visa, which is given to people in specialty occupations requiring expertise. The visa was valid through mid-2027, said Thomas S. Brown, an attorney representing her and Brown Medicine.

Alawieh was detained when she returned to Logan airport, and family members are afraid that she is about to be deported to Lebanon, he said.

“We are at a loss as to why this happened,” Brown said. “I don’t know if it’s a byproduct of the Trump crackdown on immigration. I don’t know if it’s a travel ban or some other issue.”

He said her phone has been seized and he has not been able to contact Alawieh.

Bayliss said a lawyer filed a petition with the US District Court in Massachusetts, and Judge Leo T. Sorokin issued an order saying Alawieh should not be moved outside of Massachusetts without 48 hours notice. But he said that message apparently did not reach immigration officials in time, and a plane carrying Alawieh left for Paris.

“This is outrageous,” Bayliss said in an interview. “This is a person who is legally entitled to be in the U.S., who is stopped from re-entering the country for reasons no one knows. It’s depriving her patients of a good physician.”

A US Customs and Border Patrol spokesperson, Ryan Brissette, was not able to immediately answer questions about Alawieh on Friday evening.

Bayliss said Alawieh graduated from the American University of Beirut medical school and came to the United States for a nephrology fellowship at Ohio State University. She then landed a transplant fellowship at University of Washington and had a residency in the Yale hospital system before starting at Brown Medicine last July, he said.

“She’s really a very humble and able person,” Bayliss said. “She takes care of her patients. She is talented and thoughtful and a great addition to our division.”

Bayliss said Alawieh went to Lebanon to visit parents and planned to be gone for two weeks. He said she texted a colleague at 6:30 p.m. Thursday saying she was back in Boston, but then her family heard from immigration officials.

Dr. Paul Morrissey, surgical director of the organ transplant division at Brown University Health, said Alawieh works on getting people in Rhode Island on the list for a kidney transplants, and that’s a crucial job at a time when there has been a lot of focus on the need for kidneys and their equitable distribution.

He said Alawieh should not have had any problem traveling out of the country with an H-1B visa.

“It’s an unfortunate set of circumstances,” Morrissey said. “It’s putting a strain on our office. Her work has been exceptional.”

I’ve said it before, and I’ll say it again… once upon a time, liberals did have our own “Leftist Joe Rogan”… his name was Joe Rogan…

Here he is advocating for socialized medicine, healthcare for all, and supporting labor unions to protect workers.
2) Recall, Rogan was once pro Obama and pro Bernie Sanders, and pro Yang Gang, and anti Trump. It’s sad he has since failed to the dark side. But like Vader… maybe he can be redeemed someday and come back to the light.

I'm shocked a lot of doctors don't know about this newer flu antiviral drug called Baloxavir (XOFLUZA)... that shortens your flu illness by 33%, and reduces your viral load by day 2, versus what a placebo takes 5-6 days to achieve. Baloxavir also seems superior to TAMIFLU (oseltamivir) for smashing your viral load on 2 day, achieving what takes Tamiflu 3-4 days. CDC even lists Baloxavir on their website as one of the top 4 drugs that it tracks whether it works against new flu strains (it works)Image

💣TORPEDOING MEDICAL RESEARCH—NIH indirect grant funding just got slashed by Trump to 15%. What does this mean for you? Colleges and universities won’t be able to support students, tuition will increase, especially graduate students & researchers who find cures/preventions for cancer, diabetes, heart disease, Alzheimer’s and more. This will not only raise tuition and hurt pipeline of future scientists/doctors, but COMPLETELY DECIMATE MEDICAL & PUBLIC HEALTH RESEARCH. It will also give more power to big pharma to manipulate research agendas and buy out ideas that should remain in the public domain. Ie THE RICH BIOTECH TYCOONS (eg Vivek Ramaswamy) WILL GET RICHER. The lay public will someday only see future drug/tech prices soar as biotech and big pharma control more science and make more money.

Also, Trump’s NIH posted this graphic - but it ignores that most public universities also heavily rely on indirect to subsidize tuition, and train next generation of scientists and medical doctors doing research. (Public colleges can’t compete with wealthier schools who do have endowments, and hence will fall further behind). Public colleges that do medical research will literally fall apart without this mechanism.Image
Image
2) People don’t seem to get 2 things:

📌Indirect funds college administration and facilities and support services. Academic advising, building operations, new labs and classrooms for students— where does that money come from? If not indirect grants, then it’ll have to come more from ⬆️student tuition.
