Controversy erupted when UK-based pharmaceutical giant AstraZeneca admitted that its Covid vaccine could cause blood clot-related side effects 'in very rare cases'.
Its legal document mentioned that, this vaccine could cause Thrombosis with Thrombocytopenia Syndrome (TTS) in “very rare cases”.
The very same vaccine was manufactured by the Serum Institute of India (SII) and was known in India as Covishield.
TTS is a rare condition characterized by the formation of blood clots (thrombosis) accompanied by low platelet count (thrombocytopenia).
