Dr. Samir Gupta on science working as it should with AstraZeneca's COVID vaccine

Dr. Samir Gupta, a respirologist atSt Michael's Hospital in Toronto, said what's important is that the creation of the AstraZeneca vaccine, testing, roll out,discovery of complications and stopping of vaccine distribution played out as it should for a new pandemic virus.

According to media reports, AstraZeneca previously admitted in court documents that the vaccine can cause rareside-effects such as blood clots and low blood platelet counts.

"Ultimately we can't forget that the virus is worse than the vaccine, even with this complication," Gupta said in an interview on CBC News Network.

AstraZeneca'sapplication to withdraw the vaccine was made onMarch 5 and came into effect on May 7, according to theTelegraph, which first reported the development.

The Serum Institute of India (SII), which producedAstraZeneca's COVID-19 vaccine under the brand name Covishield, stopped manufacturing and supply of the doses since December 2021, an SII spokesperson said.
