“It is admitted that the AZ vaccine can, in very rare cases, cause TTS. The causal mechanism is not known,” the company said in the court documents in February, The Telegraph reported.
“Further, TTS can also occur in the absence of the AZ vaccine (or any vaccine). Causation in any individual case will be a matter for expert evidence,” it added.
The admission by AstraZeneca runs counter to the company’s insistence in 2023 that it would “not accept that TTS is caused by the vaccine at a generic level”.
The World Health Organization confirmed that Covishield can have life-threatening side effects. “A very rare adverse event called Thrombosis with Thrombocytopenia Syndrome, involving unusual and severe blood clotting events associated with low platelet counts, has been reported after vaccination with this vaccine.”
