'At this point in time, our standard of care has been placebo-controlled trials,' said Jodie Guest, professor and senior vice chair of the department of epidemiology at the Rollins School of Public Health at Emory University.
The concern is over how Kennedy will define 'new.' It's not clear if the requirement would apply to updates of existing vaccines. For example, the pneumococcal, Hib, and measles vaccines have all been improved over the years. Most urgently, there are two vaccines — against flu and COVID — that are updated annually. The basic platform of the vaccine remains the same, but the vaccine is changed slightly to better match the strains of illness expected to be circulating in the upcoming season.

The original COVID vaccines were tested in clinical trials against placebos. But the annual COVID booster shots, similar to flu shots, are tested by giving the shots to a test population then drawing blood and measuring antibody levels, which are correlated to how much protection the person has against disease. That type of testing involves fewer people and far less time than placebo testing.
Kennedy's proposal to potentially require placebo studies for COVID boosters is neither ethical nor effective. As laid out by

Guest said requiring new placebo-based clinical trials of COVID-19 boosters would also probably take so long that it would be impossible to release annual updates — which, of course, may be exactly what Kennedy intended.
To be sure, scientists and public health officials should continue studying COVID boosters over the long term to ensure they are safe and effective. Scientists should be measuring the shots' impact on illness transmission and severity among different populations, from children to the elderly, and making recommendations accordingly. They should be monitoring reports of side effects to the national Vaccine Adverse Event Reporting System and claims made to the National Vaccine Injury Compensation Fund, along with relevant research by other government-based projects that monitor and research vaccine safety.
There may certainly be ways to improve safety monitoring for all vaccines — for example, making it easy for vaccine recipients to report side effects via mobile app or structuring databases so researchers can easily search for trends. With any vaccine, doctors should be honest about the risks and benefits so patients and families can make educated decisions.
As the Trump administration slashes government budgets, the best way to ensure vaccines remain safe and effective is by keeping in place the staff and infrastructure needed to develop, monitor, and approve vaccines. This means maintaining the databases and

But adding testing requirements that aren't science-based will only harm Americans' ability to choose the health care that's right for them.

Moderna Announces Update on Investigational Pandemic Influenza Program
Phase 1/2 H5 avian flu vaccine study shows positive interim results Company has been notified that HHS will terminate Moderna's award for late-stage development of pre-pandemic influenza vaccines CAMBRIDGE, MA / ACCESS Newswire Moderna, Inc. (NASDAQ:MRNA) today announced positive interim data from a Phase 1/2 clinical study (NCT05972174) evaluating the safety and immunogenicity of its investigational pandemic influenza vaccine, mRNA-1018, in approximately 300 healthy adults aged 18 years and older. The interim results focus on a vaccine candidate targeting the H5 avian influenza virus subtype. The Company had previously expected to advance the program to late-stage development with the U.S. Department of Health and Human Services (HHS); however, today Moderna received notice that HHS will terminate the award for the late-stage development and right to purchase pre-pandemic influenza vaccines. 'While the termination of funding from HHS adds uncertainty, we are pleased by the robust immune response and safety profile observed in this interim analysis of the Phase 1/2 study of our H5 avian flu vaccine and we will explore alternative paths forward for the program,' said Stéphane Bancel, Chief Executive Officer of Moderna. 'These clinical data in pandemic influenza underscore the critical role mRNA technology has played as a countermeasure to emerging health threats.' The Phase 1/2 study evaluated a two-dose regimen of Moderna's investigational avian influenza vaccine. mRNA-1018 demonstrated a rapid, potent and durable immune response. At baseline, pre-existing immunity was minimal, with only 2.1% of participants showing hemagglutination inhibition (HAI) antibody titers ≥1:40, an HAI titer considered to correlate with protection. At Day 43, three weeks after the second vaccination, 97.8% of participants achieved titers ≥1:40 with a 44.5-fold increase of titers from baseline. The investigational vaccine was generally well-tolerated, with no dose-limiting tolerability concerns observed. Most solicited adverse reactions were Grade 1 or 2 and did not increase significantly with number of doses or between first and second doses. Further data is expected to be submitted for presentation at an upcoming scientific meeting. Moderna will explore alternatives for late-stage development and manufacturing of the H5 program consistent with the Company's strategic commitment to pandemic preparedness.

How AI could help stop the next pandemic before it starts
Could artificial intelligence tools be used to stop the next pandemic before it starts? During the Covid pandemic, new technology developed by researchers at Johns Hopkins and Duke universities didn't exist. But, for the first time, researchers there say they've devised a revolutionary large language modeling tool - the type of generative AI used in ChatGP - to help predict the spread of any infectious disease, such as bird flu, monkeypox, and RSV. That could help save lives and reduce infections. 'Covid-19 elucidated the challenge of predicting disease spread due to the interplay of complex factors that were constantly changing,' Johns Hopkins' Lauren Gardner, a modeling expert who created the Covid dashboard that was relied upon by people worldwide during the pandemic, said in a statement. 'When conditions were stable the models were fine. However, when new variants emerged or policies changed, we were terrible at predicting the outcomes because we didn't have the modeling capabilities to include critical types of information,' she added. 'The new tool fills this gap.' Gardner was one of the authors of the study published Thursday in the Nature Computational Science journal. The tool, named PandemicLLM, considers recent infection spikes, new variants, and stringent protective measures. The researchers utilized data that had never been used before in pandemic prediction tools, finding that PandemicLLM could accurately predict disease patterns and hospitalization trends one to three weeks out. The data included rates of cases hospitalizations and vaccines, types of government policies, characteristics of disease variants and their prevalence, and state-level demographics. The model incorporates these elements to predict how they will come together and affect how disease behaves. They retroactively applied PandemicLLM to the Covid pandemic, looking at each state over the course of 19 months. The authors said the tool was particularly successful when the outbreak was in flux. It also outperformed existing state-of-the-art forecasting methods, including the highest performing ones on the Centers for Disease Control and Prevention's CovidHub. 'Traditionally we use the past to predict the future,' author Hao 'Frank' Yang, a Johns Hopkins assistant professor of civil and systems engineering, said. 'But that doesn't give the model sufficient information to understand and predict what's happening. Instead, this framework uses new types of real-time information.' Going forward, they are looking at how large language models can replicate the ways individuals make decisions about their health. They hope that such a model would help officials to design safer and more effective policies. More than a million Americans have died from Covid. It's not a matter of if there will be a next pandemic, but when. Right now, the U.S. is dealing with the spread of H5N1 bird flu, RSV, HMPV, pertussis, and measles, among other health concerns. Vaccination rates for measles have plunged since the pandemic, and general vaccine hesitancy has increased. That has resulted in fears that the nation could see decades of health progress reversed. Furthermore, U.S. health officials have acted to separate from global efforts to respond to pandemics, withdrawing from the World Health Organization earlier this year. Last month, they limited access to Covid vaccines for certain groups. 'We know from Covid-19 that we need better tools so that we can inform more effective policies,' Gardner said. 'There will be another pandemic, and these types of frameworks will be crucial for supporting public health response.'
