    Correcting this week’s misinformation: week of December 18, 2025

    Why are they studying aluminum in vaccines?

    The Claim:

    At the last Advisory Committee for Immunization Practices (ACIP) meeting, the advisors said that they would be studying aluminum used in vaccines. These CDC vaccine advisers are now questioning aluminum in vaccines, saying it can stay in the body, reach the brain, and may not have been tested well enough for long-term safety in children.

    The Facts:

    Sometimes a very small amount of an aluminum-containing adjuvant is added to vaccines to help them work better. Aluminum acts like a “booster” for the immune system, helping the body notice the vaccine and build strong protection. Because of this, children can get the protection they need with fewer shots.

    Research has shown over and over that the tiny amount of aluminum in vaccines is far below levels that could be harmful. Our bodies already handle small amounts of aluminum because it’s naturally found in food, water, and even some medicines.

    Most of the aluminum from vaccines leaves the body quickly through the kidneys. One study published in Vaccine found that the amount in vaccines is much smaller than what people take in every day from food and the environment.

    The small amount that stays in the body for a short time does not build up to dangerous levels. Vaccines save millions of lives every year, and their benefits are much greater than the very small and disproven risks sometimes claimed.

    A recent study from Denmark looked at the health of more than 1.2 million children over many years. The researchers checked for long-term problems like asthma, autism, and other ongoing illnesses. Because the study was so large and carefully done, it gives very strong evidence that aluminum in vaccines does not cause chronic health problems in children.

    Do COVID vaccines cause kidney and organ damage?

    The Claim:

    Nick Hulscher claims a study proves that COVID vaccines cause growing kidney damage, raise the chance of needing dialysis and dying, and harm every organ in the body

    The Facts:

    The study Hulscher is referring to is an observational study, which only looks at patterns in existing data. It is not the kind of study that can prove vaccines caused kidney failure or death. It can only show that two things happened at the same time. This is important because people in large medical databases like TriNetX are often older and already have more health problems, which increases their risk of kidney disease and death on its own. Hulscher does not explain this major limit of the study.

    The study uses numbers to compare risk between small groups of people. One of these numbers, called a hazard ratio, shows a relative difference, not a sudden or guaranteed risk. For example, a hazard ratio of about 1.8 for dialysis in one small group does not mean vaccinated people now have an “84% chance” of kidney failure. It only means that, within that specific group, dialysis happened more often compared to another group.

    The same problem applies to the “20% higher death rate” mentioned in the video. That number comes from a specific subgroup of people, not from everyone who got vaccinated. However, the video talks about it as if it applies to all vaccinated people, which is misleading.

    In short, these numbers compare groups in limited situations. They do not mean that everyone who gets vaccinated faces these risks.

    Claims like “these shots harm every organ” and “nothing can escape the lipid nanoparticles” are not findings from the study. They go far beyond what the data actually shows.

    Overall, the study raises questions that need more research, but the video exaggerates the risks, leaves out important details, and makes claims that the study’s authors do not make.

    Do whooping cough vaccines do good?

    The Claim:

    In a video, Dr. Suzanne Humphries claims that whooping cough vaccines are unnecessary and ineffective because deaths dropped before vaccines were introduced, the vaccines do not stop disease spread, they may cause stronger germs to develop, and natural infection protects communities better than vaccination.

    The Facts:

    Suzanne Humphries, a doctor of nephrology (kidney medicine), says she used to give vaccines to her patients, but during the 2008–2009 flu season, she was convinced that vaccines cause kidney failure and high blood pressure. She based this belief on personal experiences, not scientific evidence. Personal stories can be wrong because of mistakes or bias. In fact, the National Kidney Foundation still says vaccines are safe and recommends them.

    The United States began vaccinating against pertussis, also called whooping cough, in the 1940s. Before vaccines were widely used, about 200,000 people got the disease each year, and around 9,000 people died from it. Today, far fewer people get pertussis each year, and fewer than 15 people die from it.

    Some studies show that getting pertussis naturally may protect someone for a longer time than the vaccine does. However, before vaccines, thousands of people died from pertussis every year. Because of this, we do not agree that getting the disease naturally is better than getting vaccinated.
