Health Secretary Robert F. Kennedy Jr. is requiring all new vaccines to be tested against placebos before being licensed, officials said on April 30.
The requirement is “a radical departure from past practices,” a spokesperson for the Department of Health and Human Services (HHS) told The Epoch Times in an email.
“Except for the COVID vaccine, none of the vaccines on the CDC’s childhood recommended schedule was tested against an inert placebo, meaning we know very little about the actual risk profiles of these products,” the HHS spokesperson said.
A placebo is a substance that “has no effect on living beings,” according to the Centers for Disease Control and Prevention. The Food and Drug Administration (FDA) defines it as an “inactive preparation.” Neither agency responded to requests for comment.
Federal regulators, who are part of HHS, have not approved any vaccines since Kennedy was sworn in as health secretary in February.
Some experts say that placebo-controlled trials for established vaccines, such as the measles, mumps, and rubella (MMR) shots, would not be ethical because it would deny participants in the control arm a vaccine.
Dr. David Wohl, a professor at the University of North Carolina at Chapel Hill’s Institute of Global Health and Infectious Diseases, told The Epoch Times in an email that he believes that placebo-controlled trials are not ethical for infectious diseases for which there are vaccines.
“For infections where a vaccine does not exist, a placebo can be considered; however, this may not be ideal, as vaccines commonly cause side effects like soreness at the injection site or achiness as the body responds to the vaccine as intended,” Wohl, who worked on the trial for Pfizer’s COVID-19 vaccine, said. In those circumstances, the control group could receive an existing vaccine for another disease.
Aaron Siri, a lawyer who represents the Informed Consent Action Network, told The Epoch Times via email that “a clinical trial without a proper control cannot properly assess safety.”
“What hangs in the balance of these trials is the safety of a product typically injected into millions of healthy infants and children every year,” Siri said, noting that Congress gave vaccine manufacturers immunity from liability through the 1986 National Childhood Vaccine Injury Act.
Delay on Vaccine
The new HHS announcement was made after regulators opted against approving Novavax’s application for a license for its COVID-19 vaccine by a recent deadline, a move that officials have since attributed to how the vaccine features an updated formulation that is different from the formulations that received emergency authorization in the past.“Trials from four years ago conducted in people without natural immunity no longer suffice,” an HHS official told The Epoch Times in an email.
“A four-year-old trial is also not a blank check for new vaccines each year without updated clinical trial evidence, unlike the flu shot which has been tried and tested for more than 80 years.”
FDA Commissioner Dr. Marty Makary indicated on CBS on April 29 that the agency may not clear a new round of COVID-19 vaccines ahead of the 2025–26 virus season.
Dr. Monica Gandhi, professor of medicine and associate chief of the University of San Francisco Division of HIV, Infectious Diseases, and Global Medicine, told The Epoch Times in an email that she does not think new trials are necessary for updated formulations in light of how the vaccines were tested in human trials during the COVID-19 pandemic and how updated vaccines target newer variants of the same disease.
Building New Surveillance Systems
Kennedy, speaking in a town hall on April 28, said that “there’s no surveillance system” monitoring the safety of vaccines once they receive approval and people start receiving them.“CDC prioritizes high-quality vaccine safety research and identification of adverse events through public health surveillance,” the agency states on its website.
“It’s a system that was designed to fail,” the spokesperson said.
The spokesperson also described the Vaccine Safety Datalink as “virtually unusable for serious research” and said that both systems “have become templates of regulatory malpractice.”
“[HHS is] now building surveillance systems that will accurately measure vaccine risks as well as benefits—because real science demands both transparency and accountability,” the spokesperson said.
