    Correcting this week’s misinformation: week of August 14, 2025

    Why did HHS stop funding mRNA research?

    The Claim:

    video featuring Dr. Steven Hatfill, an HHS advisor, claims that large studies showed mRNA COVID vaccines had no benefit and were riskier than getting COVID, causing huge side effects and cell damage by flooding cells with mRNA that disrupts proteins, harms tumor-fighting genes, and hurts mitochondria.

    The Facts:

    The Department of Health and Human Services is using this compilation of studies to defend a recent decision to cut funding to mRNA vaccines. Dr. Steven Hatfill explained that meta-analyses were conducted on these studies to conclude that mRNA vaccines are dangerous.

    However, when you start looking at the studies themselves, it’s clear they are just pulling any study that merely mentions spike protein, regardless of source. The first two studies listed specifically discuss the SARS-CoV-2 virus, and barely touch on the mRNA vaccines. And in the first 10 studies, only 2 are specifically about vaccines, with one of them concluding that vaccines “may potentially reduce or prevent SARS-CoV-2 infection, leading to a significant reduction of the global health burden of this pandemic.”

    Hearing Dr. Hatfill’s comments, you could be convinced that mRNA vaccines cause cancer, but they do not. Most of the mRNA from the vaccine stays at the injection site, but some travels and is taken up by other organs.

    Like in every other situation, the mRNA will then direct those cells to produce spike proteins, which will be anchored to those cells. The mRNA will then degrade within a day or so. Because the mRNA cannot access the nucleus of the cell where DNA resides, it does not change your DNA, and it cannot, therefore, give you turbo cancer.

    Rather, the spike proteins trigger an immune response and nothing else. They are not capable of entering another cell or replicating and causing cancer. They are just on display for your immune system to learn about.

    How safe are HPV vaccines?

    The Claim:

    An old video featuring HHS Secretary RFK Jr. argues that HPV vaccination is unnecessary and dangerous for teens because the pharma company ran the trials, used an aluminum control instead of a true placebo, dismissed reports of harm as coincidences, and proved that trial deaths were 37 times higher than deaths from cervical cancer.

    The Facts:

    The claims about HPV vaccines ignore extensive scientific research from around the world. Studies have shown that the vaccine is very safe and works well to prevent cancers caused by HPV. Before it was approved, the vaccine went through careful testing, and large studies continue to prove its safety.

    The assertion that cervical cancer poses no risk to preteens and teens is misleading. HPV, the virus that causes cervical cancer, is commonly spread during adolescence and young adulthood, and getting the vaccine before being exposed to HPV gives the best protection. According to the CDC, widespread HPV vaccination programs have already led to big drops in HPV infections and pre-cancerous conditions, lowering the risk of cancer later in life.

    There’s no evidence for the claim that HPV vaccine trials had a death rate “37 times higher” than cervical cancer death. In fact, multiple research studies have found no increased risk of death or of severe events such as GBS or POTS from HPV vaccines compared to the general population.

    The World Health Organization guides the ethical use of placebos in vaccine trials in certain situations. It is acceptable when no effective vaccine is available, and the new vaccine is intended to benefit the population being studied. However, using placebos is considered unacceptable when there is already an effective and safe vaccine accessible in the public health system of the country where the trial is planned. In such cases, it would be unethical to withhold the existing vaccine from participants if not receiving it would pose a significant risk to their health.

    In some trials, researchers give a control an aluminum-adjuvant containing placebo instead of a saline placebo. Receiving a placebo with an aluminum adjuvant would feel different than receiving a pure saline placebo. Researchers choose these placebos to keep the trial randomized and blinded.

    Many vaccines use aluminum-based adjuvants to help boost the immune response. These adjuvants have been well-studied for safety and are safe in small amounts. Importantly, other studies have used saline placebos for HPV vaccines, and they found no difference in serious side effects between the vaccine and placebo groups.

    Did the DPT vaccine cause SIDS?

    The Claim:

    A widely circulating article claims that vaccines (especially the old DPT shot and large combo shots) can stop babies from breathing and cause death, that many “SIDS” cases were really vaccine deaths hidden by doctors and officials, and that deaths fell when fewer shots were given or when DTaP replaced DPT.

    The Facts:

    In the U.S., a special program called the National Vaccine Injury Compensation Program (VICP) helps people who may have been harmed by vaccines. This program exists because vaccines protect public health, and very rare adverse reactions can occur. However, vaccine makers are not free from responsibility—this system ensures claims can be handled fairly without discouraging companies from developing vaccines that save lives.

    The National Childhood Vaccine Injury Act protects vaccine makers from being sued if a vaccine causes injuries or death *as long as the side effects are unavoidable and the vaccine is made and labeled correctly.* In other words, the law stops any lawsuits that claim a vaccine’s design is defective. There is nothing to stop anyone from suing if there are issues with manufacturing, etc

    As for SIDS, meta-analyses found that there was no association or a decreased risk of  among children who received the DPT vaccine compared to children who did not.
