The flu vaccine is recommended annually for all Americans at 6 months and more, according to the Centers for the Control and Prevention of Diseases – but a new study by the clinic in Cleveland suggests that there may be no protective effects that people expect.
A preliminary study published on Medrxiv.org this week examined the data on the influenza season 2024-2025.
Researchers have found that among 53,402 Clinic officials in Cleveland in North Ohio, receiving the flu vaccine is associated with a 27% increase in influenza infections.

The vaccinated employees were compared to those who did not receive the vaccine for a period of 25 weeks.
The flu vaccine is recommended annually for all Americans at 6 months or more, according to the Centers for the Control and Prevention of Diseases.
“The flu vaccine can be highly effective to reduce the severity of the disease, prevent hospitalizations and minimize the spread of the virus, but its effectiveness may vary depending on the virus strain and individual health conditions,” said the clinic in FOX.

While the previous work of these researchers on the effectiveness of the vaccine has been published in large magazines, this latest study is still in the prior stage, which means that it has not yet been reviewed.
The researchers have noted several restrictions on the study, including that the “trivalent inactivated flu vaccine” has been used in about 99% of the employees involved.
“The possibility of other flu vaccines being more effective, it cannot be ruled out,” they wrote.
Home testing kits may have missed some infections.
“This study found that the flu vaccination of adults of work age was associated with a higher risk of flu during the respiratory season 2024-2025, suggesting that the vaccine was not effective in preventing influenza this season,” the study researchers said.
In addition, the study does not compare the risk of hospitalizations or influenza deaths, nor measures whether the vaccine reduces the severity of the disease.
The population studied also does not include children and contains very few adults or immunocompromised individuals, the researchers said.
“The results do not suggest that vaccination increases the risk of flu,” the clinic in Cleveland said. “Instead, the study suggests that the effectiveness of the vaccine this season to prevent influenza may have been limited to relatively healthy health workers.”
Dr. Mark Seagal, a clinical professor of medicine at NYU Langone Health and Fox News, a senior medical analyst, reviewed the study results and said the results were “misleading”.
“It is observed so it does not prove that the vaccine does not reduce spread,” he told Fox News Digital.

“The biggest addiction I see is that it compares the vaccinated health workers (80% are vaccinated against the flu) with common trends in the population, since the survey does not take into account that health workers are more freezing in their profession, so we would expect the percentage to be higher.
Seagl also said he believed the study abused the word “efficiency”.
The study does not compare the risk of influenza hospitalizations or deaths, nor does it measure whether the vaccine reduces the severity of the disease.
“In the flu vaccine, it is designed to reduce weight rather than reduce spread,” he noted.
“The real criterion for the effectiveness of the flu vaccine is the percentage of hospitalization or visit to a doctor’s office or emergency, which is usually reduced by over 100,000 per year or more due to the vaccine.”
This effectiveness varies from year to year based on how well the vaccine corresponds to the prevailing strain, the doctor added.
“At the same time, the flu vaccine tends to reduce viral load, which should reduce the overall spread within the community.”
Dr. Jacob Glhanville, Central CEO of Centivax, a biotechnology company in San Francisco, sounded that the survey had not yet undergone a partnership.
“We have to wait for this process as it will serve to check statistical methods and other reasons for designing research,” he told Fox News Digital.
“I still tell my patients that the benefit of getting the flu vaccine is that although you may get the flu, your case may not be as heavy as those who have not received the flu vaccine,” a doctor said.
“For example, it would be important to exclude the avoidance of reporting by non-vaginated clinic employees in Cleveland. Have they had any policies that would discourage non-vacified subjects to report illness?”
“The whole world is affected by the flu, so if this phenomenon is real, it must be easily supported by other studies this season.”

Dr. Mike Seville, a family doctor with headquarters in Salem, Ohio, agreed that the higher percentage of infection suggests that this year the flu vaccine is not as effective as it hopes.
“I wouldn’t think this is expected. Compared to the effectiveness of the annual flu vaccine in previous years, it can vary significantly, from about 10% to about 60%,” he said in an interview with Fox News Digital.
Seville said that in his office he saw increased cases of flu this season, but not necessarily as serious cases.
“I still tell my patients that the benefit of getting the flu vaccine is that although you may get the flu, your case may not be as heavy as those who have not received the flu vaccine,” he said.
