Vaccines have played a crucial role in combating the Covid-19 pandemic, helping to prevent severe illness and death. However, in an extremely rare case, a Covid booster shot reactivated tuberculosis (TB) in a 47-year-old man who had been living with a dormant infection. This unprecedented immune response raises questions about how vaccines interact with underlying health conditions, particularly in immunocompromised individuals.
This article explores how the Covid booster reawakened TB, the science behind immune system reactions, and what this case means for future vaccination strategies.
The Unusual Case: Covid Booster Triggers Tuberculosis
A 47-year-old man in India had been living with latent tuberculosis—a silent infection that remains in the body without causing symptoms. Before his Covid vaccinations, he showed no signs of active TB and had tested negative for the disease during routine screenings.
However, things took a shocking turn after his third Covid booster shot. Within just five days, he began experiencing severe symptoms, including:
High fever Excessive night sweats Extreme fatigue Painful swelling in his lymph nodes
Doctors initially suspected an autoimmune reaction, but further tests revealed that his dormant TB infection had become active, a rare occurrence known as tuberculosis immune reconstitution inflammatory syndrome (TB-IRIS).
Understanding TB-IRIS: A Hyperactive Immune Response
What is TB-IRIS?
TB-IRIS is a condition where a weakened immune system suddenly regains strength and aggressively attacks a dormant TB infection, causing excessive inflammation. It is most commonly seen in HIV patients when they start antiretroviral therapy, but this case suggests that Covid vaccines could also trigger similar immune responses in some individuals.

How Did the Covid Vaccine Play a Role?
Covid mRNA vaccines are designed to stimulate the immune system by mimicking viral proteins. This triggers the body to produce a strong defense against potential infections. However, in rare cases, the immune system may become too aggressive and start attacking latent infections like TB, which had previously been controlled by the body.
The man’s immune system, reawakened by the Covid booster, mistakenly identified his dormant TB bacteria as a new threat, leading to a full-blown inflammatory response.
A Misdiagnosed Condition: The Road to Discovery
Before this incident, the patient had been diagnosed with rheumatoid arthritis (RA)—an autoimmune condition that causes chronic joint pain. To treat RA, he was prescribed immunosuppressive drugs, which weakened his immune system and may have allowed TB bacteria to remain inactive.
But when he received his Covid booster, the sudden immune reactivation overwhelmed his body, making the TB infection spread rapidly and causing severe inflammation.
Symptoms That Led to a TB Diagnosis
The man’s initial symptoms were mistakenly linked to arthritis and Covid vaccine side effects. However, as his condition worsened, doctors conducted further tests, revealing:
Severe swelling in lymph nodes (especially in the neck) CT scan abnormalities indicating TB inflammation Biopsy confirming tuberculosis
He was immediately placed on a four-drug TB treatment plan, which led to significant improvement within five days.
A Second Shock: TB Symptoms Return After Third Booster
Just two weeks later, the man received his third Covid booster shot—and his TB symptoms returned even more aggressively.
Severe chills and fever Uncontrollable night sweats Extreme weakness
This time, doctors quickly identified TB-IRIS as the cause. His immune system had once again been overstimulated, leading to a dangerous inflammatory reaction.
How Was He Treated?
Doctors acted fast to control his immune response while keeping his TB treatment on track. His treatment plan included:
High-dose intravenous (IV) steroids for five days to calm the immune system A slow transition to oral steroids for three months Continued TB medication for over a year
By his 18-month follow-up, his TB symptoms had fully disappeared, and he was finally able to resume arthritis treatment.

What Does This Mean for Future Vaccinations?
This case does not mean that Covid vaccines cause tuberculosis. Instead, it highlights how vaccines can trigger unexpected immune responses in individuals with hidden or latent infections.
Key Takeaways for Patients with Immune Conditions:
Screening before vaccination: Patients with a history of autoimmune disorders, chronic infections, or immunosuppressive treatments should consult their doctors before getting a booster shot. Monitoring for post-vaccine symptoms: If unusual symptoms occur after a vaccine, immediate medical attention is crucial to prevent severe complications. Individualized vaccination approaches: Not everyone reacts to vaccines the same way. High-risk patients may require adjusted booster schedules or additional monitoring.
Other Inflammatory Reactions Linked to mRNA Vaccines
While mRNA vaccines are highly effective, there have been reports of immune-related side effects, including:
Myocarditis (heart muscle inflammation) Pericarditis (inflammation around the heart lining) Autoimmune disease flare-ups in some individuals
This does not mean vaccines are dangerous, but rather that certain individuals with pre-existing immune conditions may need extra precautions when receiving booster shots.
Final Thoughts: A Rare but Important Medical Case
This case of TB reactivation after a Covid booster is an extremely rare occurrence, but it serves as a reminder of how complex the human immune system is.
While vaccines remain a crucial tool in fighting infectious diseases, this case highlights the importance of personalized medicine—tailoring vaccination plans to each individual’s unique health condition.
If you or someone you know has a history of autoimmune disease, chronic infections, or immune-related conditions, it’s always best to consult a doctor before receiving a booster shot. Awareness and proactive healthcare can prevent rare complications while still ensuring protection against deadly viruses.

11 Actors Who Had a Chance to Portray a Legendary Character but Missed It
There are many ways to get a starring role. Some actors are selected during castings, while others are invited due to their popularity, which is what happened to Kate Winslet after Titanic. But not all auditions end successfully, or actors may not agree to offers made by film directors or producers. For example, Russell Crowe refused to star in Lord of the Rings because his intuition told him so.
At Bright Side, we imagined what our favorite characters would look like if other people portrayed them.
Daenerys Targaryen — Elizabeth Olsen
The actress, who has become famous for her role of the Scarlet Witch, failed auditions for the role of Mother of Dragons at the beginning of her career. Elizabeth Olsen later described what happened: “It was the most awkward audition I’d ever had. I was doing the Khaleesi speech when she comes out of the fire. It was awful. I didn’t get a callback.” As a result, Daenerys was played by Emilia Clarke.
Aragorn — Russell Crowe
Russell Crowe was asked once whether he regretted refusing to play Aragorn in the iconic trilogy, Lord of the Rings. The actor honestly replied that he had never thought about it and explained why he didn’t join the project. According to Crowe, Peter Jackson never really wanted to cast him for the role of Aragorn. Russell’s instinct told him that the director already had a suitable person in mind, so he politely declined the offer.
Ellie Sattler — Gwyneth Paltrow
In 1992, Gwyneth Paltrow wanted to get the role of Dr. Ellie Sattler. This part would’ve really helped the career of the aspiring actress because Jurassic Park had become a popular franchise. However, the future star failed, and the role went to Laura Dern.
James Bond — Henry Cavill
Now it’s hard to imagine anyone but the brilliant Daniel Craig playing this role, but Henry Cavill had a chance to become the new Agent 007. The actor was turned down because he was “a little chubby.” Cavill accepted the criticism with dignity and began to do more physical training, which helped him in his future career.
Jane Smith — Gwen Stefani
Popular singer Gwen Stefani is a truly versatile person. She almost landed the lead role in Mr. & Mrs. Smith. Stefani went to quite a few auditions, but eventually, she made a choice in favor of a musical career. And Jane Smith was played by the amazing Angelina Jolie.
Indiana Jones — Tom Selleck
The actor almost played the cheerful adventurer. Tom Selleck got the role of Indiana Jones, but by that time, he had already signed on for the Magnum, P.I. TV series, and the producers didn’t allow him to combine the 2 projects.
Prince Caspian — Nicholas Hoult
According to the actor, auditions for the role of Prince Caspian were the worst in his career. Nicholas Hoult was asked to speak with a Hispanic accent, like Puss in Boots from Shrek. Holt was embarrassed by this request because he wasn’t prepared for it. Eventually, the role went to British actor Ben Barnes, who was the perfect fit.
Viola De Lesseps — Kate Winslet
After the resounding success of Titanic, Kate Winslet received many offers from different film directors. She was invited to take part in Shakespeare in Love, but the actress refused because she wanted to work on more independent projects. Eventually, Gwyneth Paltrow landed the role. And she made the right choice, as she was awarded an Oscar for her performance.
Alex Munday — Angelina Jolie
We know from Angelina Jolie’s filmography that she loves to take part in action flicks. But still, there was a similar project the actress rejected. Drew Barrymore and Cameron Diaz did their best to convince Jolie to play their partner but to no avail.
Jolie felt she wasn’t right for this role and later explained her refusal: “I’m not at that point in my career, so audiences won’t have as much fun watching me run around in high heels chasing bad guys and flipping my hair.”
Patrick Bateman — Johnny Depp
Initially, American Psycho was supposed to be directed by Stuart Gordon. The director saw only Johnny Depp in the main role and persuaded him to take it. But the author of the novel abruptly changed his mind. He pulled Stuart Gordon’s rights to the book and called Johnny Depp a lightweight actor who was too old to play the part. Depp was 28 at the time.
Christian Grey — Charlie Hunnam
In 2013, all the newspapers announced the news of the year: Charlie Hunnam would star in the screen adaptation of Fifty Shades of Grey. But a few months later, the actor changed his mind and refused the role. As it turned out, Hunnam had a nervous breakdown due to his busy work schedule.
The actor realized that he wouldn’t be able to do his job properly, but this decision was very difficult for him. Hunnam hasn’t seen any of the films in the trilogy because he called that situation “the worst professional experience” of his life.
