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.

Cashier Learns She Owns a $3.8M Business after Finding Will in Her Name — Story of the Day

An unusual letter provides the catalyst for one woman to uncover a secret kept from her for years, and receive unexpected wealth.
Gregory locked the door to the small corner shop where he’d worked as a cashier for the last twenty years. His coat was too old and thin to keep the chill from his bones as he walked home, but he smiled nonetheless. It had been another great day at work.
Gregory’s wife had never understood how he found satisfaction in what she called a low-level job. She’d left him because she felt he lacked ambition, but he still had his daughter.

Linda was standing in the foyer of the apartment block where she and Gregory lived when he entered the building. She had also recently started working as a cashier and still wore her uniform. In one hand, she held a letter.
“What have you got there, Linda?” Gregory asked as he approached her.
Linda looked up, startled. “You tell me, Dad. I’m too scared to open it.”
Gregory frowned and took the letter from his daughter. The name of a legal practice was printed on the envelope.
“Why would a lawyer be contacting me?”
Gregory shrugged. He tore the envelope open and studied the papers inside. His jaw dropped, and his fingers began shaking as he read.

“It’s bad, isn’t it?”
“It’s… strange. According to this letter, somebody has left you a business comprising three restaurants, and it’s worth nearly four million dollars.”
“What!” Linda snatched the letter from Gregory’s hands. “It’s got to be a scam.”
“I did this to find out whether you’re a good person.”
“There’s an easy way to find out.” Gregory leaned over to indicate the lawyer’s phone number on the letterhead.
Linda called the lawyer and arranged a meeting for the next day. Gregory accompanied her.

“This has got to be a mistake,” Linda told the lawyer when they entered his office.
“I don’t know anyone who would leave me a business.”
The lawyer shook his head. “There’s no mistake, Miss. My client, Matthew Markham, was very particular in his instructions.”
Gregory felt as though he’d been electrocuted. “Please, say that name again.”
“Matthew Markham.”
Gregory understood everything then. He hung his head and burst into tears.

A few months earlier…
Matthew shivered with anxiety as he approached the cashier. He set down the packet of gum and stared at the man who rang it up. The nametag on his chest said ‘Gregory.’ He was the right man.
“Sir? Are you okay?”
“Fine.” Matthew realized he’d zoned out and handed the cashier a five-dollar bill. “But I do need to talk to you. It’s about Linda.”
The man looked up sharply at the customer who had just uttered his little daughter’s name. “Is she in some kind of trouble?”
Matthew shook his head. “Do you have a few minutes, please?”

Matthew and Gregory arranged to meet at a diner nearby during Gregory’s lunch break. While Matthew waited, he thought over the revelations that had brought him to this point.
A few days earlier, he’d been discussing his terminal illness with a close friend, Jeremy, and lamenting that he had no heirs to whom he could leave his restaurant business.
Then Jeremy dropped a bombshell on him: Matthew had a daughter he didn’t know about. His ex-girlfriend had died in childbirth, and the baby was placed up for adoption.
Matthew immediately hired a detective to track her down. Days later, he was finally sitting down with Gregory, the man who’d adopted his daughter.
Matthew explained to Gregory that he was Linda’s biological father and then asked the question that was foremost in his mind:
“Does Linda know she was adopted?”

“No, and you can’t tell her, sir.” Gregory looked at him pleadingly. “My wife left me a couple of months back, and I can’t lose Linda too. Please, don’t take her from me.”
Matthew was torn. He wanted to know his daughter but didn’t want to cause problems for the man who’d raised her. He also didn’t want to upset his daughter’s life by introducing himself when he only had a few months more to live.
“What is she like?” Matthew asked. “Is she a good person?”
Gregory smiled. “She’s an amazing person. She’s kind and treats everyone equally.”
Matthew nodded. He was starting to get an idea.

The next day, Matthew disguised himself as a poor man and went to the store where Linda worked as a cashier. He took a few essential food items to her checkout and waited while she rang them up.
“I’m sorry, Miss,” he said once she told him the cost.
“I can’t afford all of that. I’ve only got ten dollars.”
“Don’t worry about it, sir.” Linda smiled at him. “I’ll cover the rest.”
Matthew left the store and returned a week later. This time, he wore his finest suit. He chose several of the most expensive items in the store and again went to Linda’s checkout.
“Get out of the way,” Matthew shouted as he pushed his way to the front of the queue. “I’m in a hurry and need to be served fast.”

He set his purchases down in front of Linda and waved his hands at her. “Hurry up, girl, I’ve got an important meeting to attend.”
“Then you’ll have to tell them you’re going to be delayed.” Linda pushed his purchases aside and gestured to the woman behind him. “You’re next, ma’am.”
“I need to be served first!” Matthew exclaimed.
“That’s too bad, sir. I don’t allow anyone to push to the front of the queue, no matter how important you think you are.”
Matthew grinned from ear to ear. “I’m glad you said that.”

He reached for a bouquet of yellow lilies and placed the cash to pay for them on the counter. “These are for you, Linda. My name is Matthew, and I did this to find out whether you’re a good person.”
“Do me one favor, please, and remember my name when you see these lilies.”
Present day…
“Matthew is the name of your biological father, Linda,” Gregory said. “You’re adopted.”
“Why did you never tell me?”
“I’m so sorry. I never wanted you to feel bad about it. Then your mother left, and I was afraid you’d leave me too if you knew I wasn’t your real father.”

Linda hugged him. “I’d never do that, dad.”
The lawyer cleared his throat. “As I was saying, my client bequeathed his three restaurants to you, his sole heir, when he passed away a month ago. These restaurants are each worth over a million dollars.”
“Mr. Markham also had a special request. He wanted me to give you something.”
The lawyer left the room and soon returned with a bouquet of yellow lilies, which he presented to Linda.

Linda cradled the flowers in her arms. “I understand now.” She turned to Gregory. “He came into my shop once and asked that I remember his name when I see yellow lilies.”
Gregory placed a hand on Linda’s shoulder. “I’m sure he was very proud of you, Linda, and will continue to be proud of you from heaven.”
What can we learn from this story?
Treat people equally, and you will be rewarded. Matthew was encouraged to leave his business to Linda when he saw that she was a good person.
One can find happiness in a simple life. Gregory and Linda were both happy to work as cashiers and earn an honest living.
