"It is admitted that the AZ vaccine can, in?very rare?cases, cause TTS. The causal mechanism is not known...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,"?AstraZeneca said.
What complainants allege?
AstraZeneca is being sued for over ?100 million (a little over Rs 1,000 crore) by those who suffered health complications, allegedly after receiving the COVID-19 vaccine shots.
