For Latest Updates, Current Affairs & Knowledgeable Content.


British Pharma giant AstraZeneca has admitted that its Covishield Vaccine can, in rare instances, cause a side effect known as Thrombosis with Thrombocytopenia Syndrome (TTS).

What is TTS?

TTS is a rare condition in which blood clots form in unusual places in the body, and platelet count in the blood drops.


TTS is classified into two tiers by the CDC:

Tier 1:

  • Rare blood clots like in the brain/gut, sometimes alongside more typical ones in the legs/lungs.
  • Low Platelet count (below 1,50,000/ml)
  • Usually more severe & more common in young people.

Tier 2:

  • Common blood clots in legs or lungs.
  • Low Platelet Count (below 1,50,000/ml)


  • Severe Headache
  • Stomach Pain
  • Swelling in legs
  • Breathing trouble
  • Problems with thinking or seizures.
