The company voluntarily withdrew the "marketing authorization" of its Covi vaccine, which was sold as Covishield in India and Vaxzevria in Europe. According to the Telegraph report, it will no longer be used in the European Union.

While the company had applied to withdraw the vaccine on March 5, it came into effect on Tuesday.

AstraZeneca, credited with saving more than six million lives, admitted in legal documents submitted to the High Court in February that its Covid vaccine 'can cause TTS in very rare cases', the report said.

Thrombotic thrombocytopenic syndrome (TTS) is a rare side effect that can cause blood clots and low blood platelet counts in people, which has been linked to at least 8 deaths in the UK as well as hundreds of serious injuries.

The British-Swedish pharmaceutical multinational is also being sued by more than 50 alleged victims and grieving relatives in a High Court case in Britain.

However, AstraZeneca said the vaccine was being withdrawn for "commercial reasons" and had "nothing to do with the court case", and "the timing was completely coincidental".

Due to multiple Covid variants and related-vaccines, there is "a glut of available vaccines. This has led to a decline in demand for Vaxzeveria, which is no longer being manufactured or supplied. AstraZeneca has therefore decided to withdraw the marketing authorizations " For Vaxzevri within Europe,” the company said in a statement.

The company noted that it would "cooperate with global regulatory authorities to initiate the withdrawal of marketing authorization for Vaxzevria where no future commercial demand for the vaccine is expected".
