Do You Believe the Flu Vaccine Increases Your Risk of Getting the Flu?

Here’s The Scoop

As flu season approaches, a new study from Cleveland Clinic raises questions about the effectiveness of the annual influenza vaccine, a staple recommendation from the Centers for Disease Control and Prevention (CDC) for all Americans aged six months and older. This study, published on MedRxiv.org, analyzed data from the 2024-2025 flu season and found some surprising results.

In examining 53,402 employees at Cleveland Clinic in northern Ohio, researchers discovered that those who received the flu vaccine actually experienced a 27% increase in flu infections compared to their unvaccinated colleagues over a 25-week period. This finding challenges the conventional wisdom that the flu shot is a reliable shield against the virus.

However, it’s important to note that this study is still in the pre-print stage, meaning it hasn’t undergone the rigorous peer-review process yet. The researchers themselves acknowledged certain limitations, such as the use of the “trivalent inactivated influenza vaccine” for 99% of participants and the potential for home testing kits to miss some infections. Additionally, the study did not evaluate flu-related hospitalizations or deaths, nor did it assess whether the vaccine reduced the severity of illness.

Dr. Marc Siegel, a clinical professor of medicine at NYU Langone Health and a Fox News senior medical analyst, cautioned that the study’s results might be misleading. He pointed out that the observational nature of the study doesn’t definitively prove the vaccine’s ineffectiveness in reducing the spread of the virus. He also noted that healthcare workers, who make up the study’s sample, are more frequently exposed to the flu, which could skew the results.

Dr. Siegel emphasized that the real measure of the flu vaccine’s effectiveness is its ability to reduce hospitalizations and doctor visits, which typically decrease by over 100,000 annually due to vaccination. He also highlighted that the vaccine’s effectiveness varies year to year, depending on how well it matches the predominant flu strain.

Dr. Jacob Glanville, CEO of Centivax, echoed the need for caution, suggesting that the peer-review process will help verify the study’s findings. He raised questions about potential biases, such as whether non-vaccinated employees were less likely to report illnesses.

Dr. Mike Sevilla, a family physician from Salem, Ohio, noted that while this year’s vaccine might not have been as effective as hoped, the flu vaccine’s effectiveness has historically ranged from 10% to 60%. He reassured patients that even if they contract the flu, the vaccine can still lessen the severity of the illness.

As the debate over flu vaccine effectiveness continues, it’s clear that more research is needed to fully understand its impact. In the meantime, Americans are encouraged to consult their healthcare providers for personalized advice on vaccinations.
