A new Cleveland Clinic study found that the 2024-2025 flu vaccine did not prevent influenza. Quite the contrary, actually, those who took it were MORE LIKELY to get infected.
Here is the study. Read it for yourself.
It was published by doctors from the Cleveland Clinic but it has not yet been peer reviewed given the data was collected through March 26.
The employees of the Cleveland Clinic were required to get the flu shot so 82% of them did. They followed up with 53,000 employees and found that the vaccinated and unvaccinated were getting infected with the flu at an even pace but “over the course of the study the cumulative incidence of influenza increased more rapidly among the vaccinated than the unvaccinated. In an analysis adjusted for age, sex, clinical nursing job, and employment location, the risk of influenza was significantly higher for the vaccinated compared to the unvaccinated state.”
They say that the vaccine effectiveness may have waned or may not have included the most prevalent strain of flu. But that is a problem every year. Vaccine makers come up with the formulation in the spring and make their best guess as to which strains to include that they think will be prevalent in the coming months. They can never accurately predict.
A few weeks ago, the FDA approved the 2025-2026 flu vaccine and it contains strains of flu that are dominant in the world now.
It is worth noting that the annual flu vaccine does not go through clinical trials. It also is not tested as to whether or not it stops infection in humans. It is only tested to see if recipients produce antibodies.
From this study alone, it is clear we need more research about why we mandate the flu vaccine if it is this ineffective and may in fact make people MORE likely to get the flu.
