According to reports, the petition was filed by a 41-year-old man, Asif Riaz, from Chennai who demanded an interim injunction on the administration of Covishield to the public and a compensation of Rs 5 crore for the side effects incurred after undergoing the vaccine trial.


As per IANS, Riaz in the petition stated that he suffered from acute neuro encephalopathy days after taking the vaccine shot and his health deteriorated. 


Coronavirus vaccine Covishield is made by Oxford-AstraZeneca and manufactured by the Serum Institute of India. The vaccine is sold at a price of Rs 1,000 per dose in private markets. It is one of the two vaccines that have been granted emergency use approval in India. 


However, the petitioner has urged the court to declare Covishield as "unsafe" claiming that he developed multiple complications and was hospitalised for 16 days after administering the vaccine.

The high court has asked the Centre and DCGI to reply by March 26.
