Explained: Why AstraZeneca has withdrawn Covid-19 vaccine sales, and what it means for India – Forbes India

While the Serum Institute of India has not yet made any statements of withdrawal, experts say that eventually, all 'monovalent' vaccines, or those that deal with the original Wuhan strain of Covid-19, will be discontinued

Multi-national pharmaceutical company AstraZeneca has announced that it will withdraw sales of its Covid-19 vaccine globally, since there is a surplus of more updated vaccine options that target new variants of the virus, as per a report in The Telegraph. The AstraZeneca vaccine is called Vaxzevria, and, in India, its sold as Covishield, developed and manufactured by the Pune-based Serum Institute of India. It has been administered through 175 crore doses across the country.

The number of people affected constitutes such side effects as rare. In India too, families of individuals such as Karunyas, are pursuing legal action against AstraZeneca and the Serum Institute of India. Karunya was jabbed with Covishield and died in July 2021, a month after taking the vaccine, due to multisystem inflammatory syndrome. Covishield has been very well-tested. It has gone through all the scientific analysis and trials and it is a very, very safe vaccine. There is no need to panic, says Dr Rakesh Sharma, director of Tata Institute for Genetics and Society. We are incredibly proud of the role Vaxzevria played in ending the global pandemic, a statement by AstraZeneca says. According to independent estimates, over 6.5 million lives were saved in the first year of use alone and over three billion doses were supplied globally. Our efforts have been recognised by governments around the world and are widely regarded as being a critical component of ending the global pandemic. As multiple, variant Covid-19 vaccines have since been developed, there is a surplus of available updated vaccines. We will now work with regulators and our partners to align on a clear path forward to conclude this chapter and significant contribution to the Covid-19 pandemic, the statement continued. According to reports, neither has SII announced any plans to discontinue the vaccines production so far, nor has it undertaken manufacturing of new batches in the past two years. However, experts predict that all monovalent vaccines, or those that deal with the original strain, will be withdrawn and replaced with updated vaccines.
