AstraZeneca withdraws the authorization of the vaccine in the EU. This is what the Anglo-Swedish company says: «Considering the quantity of available and effective vaccines for the new variants of Covid-19, there was no longer any demand for the vaccine Vaxzevria which consequently was no longer produced or distributed. Therefore, we do not foresee future demand for the product, we read in a note sent to Adnkronos Salute. «AstraZeneca has therefore decided to withdraw the marketing authorization for Vaxzevria within the EU», specifies the company.
The decision
AstraZeneca’s decision comes just days after the admission in court documents during legal proceedings in London. The pharmaceutical giant is being sued in a class action over its vaccine developed with the University of Oxford. Lawyers argue that the drug would have produced a side effect. AstraZeneca disputes the allegations but accepted, in a legal document submitted to London’s High Court in February, that its Covid vaccine “may, in very rare cases, cause TTS”, a thrombosis with thrombocytopenia syndrome. Fifty-one cases have been lodged in the High Court, with victims and relatives seeking damages worth an estimated up to £100 million. The first case was filed last year by father-of-two Jamie Scott, who was left with a permanent brain injury after developing a blood clot and brain haemorrhage after receiving the vaccine in April 2021.
The letter
In a response letter sent in May 2023, AstraZeneca told Scott’s lawyers that it did not accept that TTS was “caused by the vaccine at a generic level”. However, “It is accepted that the AZ vaccine can, in very rare cases, cause Tts. The causal mechanism is not known” and “furthermore, Tts can occur even in the absence of the AZ vaccine (or any vaccine). The causal link in each individual case will be tested by experts.” AstraZeneca stressed in any case that the product information relating to the vaccine was updated in April 2021, with the approval of the UK regulator, to include «the possibility that the AstraZeneca-Oxford vaccine may, in cases very rare, be a trigger for TTS.”
