Pune-based manufacturer of immunobiological drugs, Serum Institute of India on Tuesday claimed that its anti-Covid-19 vaccine, Covishield being developed is completely safe and immunogenic. The company also firmly refuted claims that the Covishield the anti-Covid-19 vaccine has side-effects. "Covishield is safe & immunogenic, the incident with the Chennai volunteer no way induced by the vaccine," the Pune-based company asserted. The clarification from the company came after a Chennai-based man claimed that he suffered neurological and psychological side effects taking a shot of Covid-19 vaccine Covishield during the human trial being conducted by Serum Institute of India. "While the Serum Institute of India is sympathetic to the volunteer`s medical condition, there is absolutely no correlation between the vaccine trial and the medical condition of the volunteer. The volunteer is falsely laying the blame for his medical problems on the COVID vaccine trial,'' the company said.
