AstraZeneca and the European Commission have reached an agreement that ends legal proceedings over the execution of the Advance Purchase Agreement for the delivery of the COVID-19 vaccine Vaxzevria (ChAdOx1-S [Recombinant]).
Under the agreement, AstraZeneca commits to deliver 60 million doses of the vaccine by the end of the third quarter 2021, 75 million by the end of the fourth quarter 2021 and 65 million by the end of the first quarter 2022. Member States will be provided with regular delivery schedules, and capped rebates will apply in the event of any delayed doses.
Ruud Dobber, Executive Vice President, BioPharmaceuticals Business Unit, AstraZeneca, said: “I’m very pleased that we have been able to reach a common understanding which allows us to move forward and work in collaboration with the European Commission to help overcome the pandemic. We are fully committed to manufacture Vaxzevria for Europe following the release for supply of more than 140 million doses to date at no profit. We are also looking forward to working with the European Commission in a joint effort to further support COVAX.”
To date, AstraZeneca and its partners have supplied more than 1.1 billion doses of vaccine to over 170 countries; approximately two thirds have gone to low- and lower-middle-income countries.
In clinical trials, Vaxzevria demonstrated 100% efficacy against severe disease and hospitalisation after two doses.1,2 Real-world evidence shows the vaccine is around 90% or higher effective against WHO-identified variants of concern.3 Vaxzevria has been shown to be generally well tolerated. Incidents of thrombosis with thrombocytopenia (TTS) have been reported in a small number of people. Early diagnosis allows appropriate treatment of these events4,5 and there is no elevation of the risk of TTS at the second dose, compared to the rates expected in the general population.6
Vaxzevria (ChAdOx1-S [Recombinant])
Vaxzevria was co-invented by the University of Oxford and its spin-out company, Vaccitech. It uses a replication-deficient chimpanzee viral vector based on a weakened version of a common cold virus (adenovirus) that causes infections in chimpanzees and contains the genetic material of the SARS-CoV-2 virus spike protein. After vaccination, the surface spike protein is produced, priming the immune system to attack the SARS-CoV-2 virus if it later infects the body.
The vaccine has been granted a conditional marketing authorisation or emergency use in more than 90 countries across six continents. More than one billion doses of Vaxzevria/COVID-19 Vaccine AstraZeneca have been supplied to more than 170 countries worldwide, including more than 129 countries through the COVAX Facility.
