A recent study conducted by Mayo Clinic researchers has unveiled that receiving a COVID-19 vaccine not only curtails the risk of developing long-haul COVID but could also mitigate the severity of symptoms in individuals who develop this condition.

This research, published in the Journal of Investigative Medicine, is pivotal in understanding the extensive protective aspects of COVID-19 vaccines against prolonged and debilitating post-infection symptoms.

The study is led by Greg Vanichkachorn, M.D., medical director of Mayo Clinic’s COVID Activity Rehabilitation Program, who expressed surprise at the findings, emphasizing the crucial role vaccines play in reducing the severity of long-haul COVID.

The research comprised 477 patients who received treatment for long-haul COVID at Mayo Clinic between May 27, 2021, and July 26, 2022. More than half of these patients were vaccinated before contracting the virus.

Key Findings

Vaccinated individuals exhibited a reduced likelihood of experiencing symptoms such as abdominal pain, chest pain, dizziness, and shortness of breath.

Vaccinated patients were 50% less likely to experience abdominal pain compared to their unvaccinated counterparts.

No significant difference was observed in reports of fatigue, muscle pain, and tachycardia between vaccinated and unvaccinated patients.

Global Impact

With over 768 million confirmed cases of COVID-19 globally, as per the World Health Organization, an estimated 20% under 65 and 25% over 65 develop long-haul COVID-19.

This research offers hope, suggesting a potential alleviation of the prolonged struggle with such symptoms for millions affected worldwide.

The study underscores the importance of COVID-19 vaccines in diminishing the repercussions of long-haul COVID.

It highlights that beyond preventing infection, vaccines can play a pivotal role in lessening the severity of long-haul symptoms, enhancing overall post-COVID quality of life.

Need for Further Research

Dr. Vanichkachorn emphasized the need for more extensive research to explore the relationship between COVID-19 vaccines and long-haul COVID symptoms, particularly concerning emerging virus variants.

A deeper understanding of the cellular interactions causing these symptoms can pave the way for more targeted and effective treatments for long-haul COVID.


This research offers a renewed perspective on the multifaceted benefits of COVID-19 vaccines, highlighting their role in reducing the severity of long-haul COVID symptoms.

It serves as a beacon of hope for those battling prolonged post-COVID conditions, and reinforces the importance of widespread vaccination to combat the ongoing repercussions of the pandemic.

The findings are instrumental in guiding future research, potentially unlocking new therapeutic avenues for long-haul COVID sufferers.
