Covid-19 vaccine AstraZeneca

Covid-19 vaccine AstraZeneca, now Vaxzevria ®

The University of Oxford partnered with the British-Swedish company AstraZeneca to develop and test a coronavirus vaccine known as ChAdOx1 nCoV-19 or AZD1222.

''Covid-19 Vaccine AstraZeneca is a monovalent vaccine composed of a single recombinant, replication-deficient chimpanzee adenovirus (ChAdOx1) vector encoding the S glycoprotein of Sars-CoV-2. The Sars-CoV-2 S immunogen in the vaccine is expressed in the trimeric pre-fusion conformation; the coding sequence has not been modified in order to stabilise the expressed S-protein in the pre-fusion conformation. Following administration, the S glycoprotein of Sars-CoV-2 is expressed locally stimulating neutralising antibody and cellular immune responses, which may contribute to protection to covid-19.''
