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.

Find the hidden snake in the picture
Ever found yourself staring at a picture, trying to locate a hidden snake that seems to disappear into the scenery? These puzzles can be both fun and frustrating. But don’t worry—if you’ve ever struggled with spotting that sneaky serpent, you’re not alone.
Common Mistakes People Make in Snake Puzzles

It’s easy to fall into certain traps when trying to solve these puzzles. Let’s take a closer look at the pitfalls and how to avoid them.
1. Relying on Quick Scanning
Most people think a quick glance will do the trick, expecting the snake to jump out at them. Unfortunately, snakes are camouflage experts. Their ability to blend seamlessly into their surroundings means you need more than a casual look to spot them.
2. Ignoring Small Details
When searching for the snake, it’s tempting to focus on the big, obvious parts of the image. However, snakes often mimic the tiniest details, like the texture of a leaf or the pattern of moss. Skipping over these subtle elements can cost you.
3. Overlooking Shadows and Shapes
A snake’s body can resemble just about anything—a branch, a crack, or even a shadow. Many solvers disregard these features as unimportant, but doing so might mean missing the snake entirely.
Step-by-Step Guide to Spot the Snake
If you’re stuck, don’t sweat it. Follow these steps to approach the puzzle like a pro:
Step 1: Divide the Image into Sections
Instead of trying to take in the entire image at once, break it down into smaller sections. Focus on one part at a time, starting from the top left and moving systematically across and down the image.
Step 2: Look for Patterns
Snakes often blend by mimicking the patterns in their environment. Study the textures of leaves, bark, or rocks. A snake’s scales might align with these patterns, making it tricky to differentiate.
Step 3: Search for Curved Shapes
Unlike most elements in nature, a snake’s body typically has smooth, curved lines. Scan for anything that looks coiled or flowing, particularly in areas where you might expect a snake to hide, like near rocks or leaves.
Step 4: Pay Attention to Shadows
Sometimes, a snake’s shadow or the subtle way it disrupts lighting can reveal its position. Look closely at areas where light and shadows seem unnatural or mismatched.
Step 5: Zero In on the Highlighted Area
Still can’t find it? Here’s a tip: focus on the right side of the image, the snake’s head is hidden in the leaves. The snake is in the circle below.

The Reveal: Did You Spot It?
If you analyzed the highlighted area carefully, you probably found the snake nestled among the leaves. Its natural camouflage makes it almost indistinguishable from the forest floor. This ability to blend so effectively is a survival skill, keeping snakes safe from predators and hidden from prey.
