Serum Institute Says It Had Disclosed Rare Side Effects Of Covishield In 2021

The Serum Institute of India Pvt. said on Wednesday that it had disclosed all rare-to-very-rare side effects of its Covid vaccine Covishield—including thrombosis with thrombocytopenia syndrome—in the packaging insert in 2021.

Since the demand for previous vaccines diminished due to high vaccination rates in 2021 and 2022, the company has stopped the manufacture and supply of additional doses of Covishield since December 2021, it said.

Despite the challenges faced during the pandemic, the safety of the vaccine was their priority, it said. Both vaccines—AstraZeneca's Vaxzervria or Covishield—have been instrumental in saving millions of lives worldwide, according to the company.

"We commend the collaborative efforts of governments and ministries in facilitating a unified global response to the pandemic," it said.
