Doctors have revealed an extremely rare case that saw the Covid vaccine reawaken a deadly virus inside a man’s body.
The unnamed 47-year-old had been living with a dormant tuberculosis infection that was not causing symptoms when he received his booster shot in India.
Five days after vaccination he he began experiencing ‘severe constitutional symptoms’ including fever, fatigue and night sweats.
Doctors discovered that his immune system, now stronger from the vaccine, started attacking the TB infection too aggressively, causing inflammation and the flare-up of symptoms.
He was diagnosed with tuberculosis immune reconstitution inflammatory syndrome (TB-IRIS), marking the first known case linked to a Covid booster.
He was treated with high dose steroids that helped control the immune system’s overreaction, and he gradually stopped using them over several weeks as he recovered.
Tuberculosis replaced Covid to become the top cause for infectious disease-related deaths in 2023 and has been the number one killer since.
Around 8million people are diagnosed globally each year and more than a million die.
