The US Department of Health and Human Services said it will require that all new vaccines be tested in placebo-controlled trials before they’re licensed for use, raising urgent questions about the system used to clear updated Covid-19 boosters each respiratory virus season. “Under Secretary Kennedy’s leadership, all new vaccines will undergo safety testing in placebo-controlled trials prior to licensure — a radical departure from past practices,” HHS said in a statement Wednesday. Covid-19 vaccines, first cleared by the US Food and Drug Administration in late 2020, have been updated each year in a system similar to that used for flu vaccines, so they can better target circulating strains of the virus. The vaccine constructs remain the same each year, but the version of the virus they protect against can be tweaked. The FDA typically selects strains for the updated vaccines in June so they can be ready for distribution by the fall. Experts warn that requiring placebo-controlled trials before clearing new versions - which could involve enrolling participants, giving some the vaccine and some a placebo shot, and waiting some period of time to assess safety and efficacy - would delay availability of updated Covid shots by months, putting vulnerable people at risk. “The advantage of updating the vaccine every year to make it more close to the circulating strain is, you get better antibody responses, so for four to six months,you will clearly have better protection against mild to moderate disease, and that matters especially for people who are more frail,” particularly people 75 and older, said Dr. Paul Offit, a vaccine scientist at the Children’s Hospital of Philadelphia. A spokesperson for HHS didn’t immediately respond to an inquiry about whether the new guidance pertains to updated Covid-19 vaccines, but an official told CNN on Saturday that “the covid vaccines, including new ones by Pfizer and Moderna, are new and must have more gold standard science to ensure safety and efficacy for the public.” The official drew a distinction from the flu shot, “which has been tried and tested” for decades. Questions about the fate of Covid vaccines began to swirl after the FDA missed an April 1 deadline to decide whether to grant full approval to the Novavax vaccine, the only non-mRNA vaccine available to protect against the coronavirus; Novavax’s shot uses a more traditional protein-based technology. A source familiar with the situation, who wasn’t authorized to speak on behalf of the agency, told CNN that the vaccine had been on track to be approved. Novavax later said the FDA had requested a “postmarketing commitment” for a clinical trial, suggesting that a study would be required of the vaccine after it received full approval (it had been available through emergency use authorization since 2022). HHS’s newest statement adds to questions about whether a trial would be required before approval, not just for Novavax’s vaccine but also for updated versions of those from Moderna and Pfizer. Experts said that if that’s the case, it would signal a new standard for Covid vaccines. “FDA clearly, after a deliberative process, adopted an approach that treated Covid-19 vaccine boosters like influenza boosters, not like a new product, and held to that over a few years,” said Dorit Reiss, a professor of law at UC Law San Francisco. “They adopted a standard, and now they’re changing it.” Although Covid-19 has become less deadly since the height of the pandemic as the population developed widespread immunity through both infection and vaccination, the virus still kills and can be especially dangerous for the elderly. Between September 2023 and August 2024, there were more than 36,000 deaths from Covid-19 among people 65 and older, CDC data showed. In its statement Wednesday, HHS also claimed that current systems for monitoring vaccine safety, including the Vaccine Adverse Event Reporting System and the Vaccine Safety Datalink, don’t capture vaccine injuries sufficiently and “have become templates of regulatory malpractice.” HHS said it’s building surveillance systems now “that will accurately measure vaccine risks as well as benefits.” Offit, who co-invented a rotavirus vaccine and serves on the FDA’s independentpanel of vaccine advisers, said the assertion that those systems are inadequate is false. “Where’s the evidence for that?” he asked. “I would argue all the evidence is on the other side.” He pointed out that within weeks, the systems picked up very rare side effects such as myocarditis, or inflammation of the heart muscle, that happened in about 1 in 50,000 people who received mRNA Covid-19 vaccines and rare blood clots in people who received a now-discontinued vaccine using a different technology from Johnson & Johnson that affected about 1 in 250,000. “That’s very good,” he said. “This sort of notion that people have lost faith in vaccines because of the lack of safety surveillance systems is wrong.”

TruthLens AI Summary
The U.S. Department of Health and Human Services (HHS) has announced a significant policy change requiring that all new vaccines undergo placebo-controlled trials before receiving approval for use. This decision raises critical concerns regarding the current procedures for updating Covid-19 boosters, which have traditionally been adapted each year in a manner akin to the flu vaccine. The HHS statement, made under Under Secretary Kennedy's guidance, indicates a shift towards more rigorous safety testing, contrasting with previous practices where updated vaccines were cleared more rapidly. Experts in the field, however, caution that implementing such trials could lead to substantial delays in the availability of updated Covid-19 shots, potentially endangering vulnerable populations, particularly the elderly who are at higher risk of severe illness. Dr. Paul Offit, a vaccine scientist, emphasized the importance of timely updates to the vaccine to enhance antibody responses during peak circulation of the virus, noting that this is especially crucial for older individuals who may be more susceptible to the disease.
The announcement has also prompted questions about the implications for existing and upcoming Covid-19 vaccines, such as those developed by Pfizer and Moderna, as well as Novavax, the only non-mRNA vaccine currently available. The FDA's recent failure to meet a deadline for full approval of the Novavax vaccine has further fueled speculation about the future of Covid vaccine approvals under the new guidelines. HHS's claims concerning the inadequacy of current vaccine safety monitoring systems have sparked debate, with experts like Dr. Offit arguing that existing systems have effectively identified rare side effects associated with Covid-19 vaccines. This evolving landscape indicates a potential shift in regulatory standards for Covid vaccines, raising concerns among health professionals about the balance between ensuring safety and maintaining timely access to vaccines that can protect public health during ongoing viral threats.
