Actual (reported)Since late December 2019, the novel human coronavirus (SARS-CoV-2) first reported in China, has spread worldwide. Vaccines to prevent SARS-CoV-2 infections have been developed in record time and several candidate vaccines have completed Phase 2a/b and Phase 3 clinical trials. Coronaviruses (CoVs) are spherical, enveloped viruses with positive-sense single-stranded RNA genomes. One fourth of their genome is responsible for coding structural proteins, such as the Spike (S) glycoprotein, envelope, membrane, and nucleocapsid proteins. Envelope, membrane, and nucleocapsid proteins are mainly responsible for virion assembly whilst the S protein is involved in receptor binding, mediating virus entry into host cells during CoVs infection via different receptors. SARS-CoV-2 belongs to the phylogenetic lineage B of the genus Betacoronavirus and it recognizes the ACE2 as the entry receptor. It is the seventh CoV known to cause human infections and the third known to cause severe disease after SARS-CoV and MERS-CoV. AZD1222 is a recombinant replication-defective chimpanzee adenovirus vaccine expressing the SARS-CoV-2 S surface glycoprotein. Development of AZD1222, previously referred to as ChAdOx1 nCoV-19, was initiated by the University of Oxford, UK, with subsequent transfer of development activities to AstraZeneca. The ChAdOx1 platform has been used in 14 clinical studies sponsored by the University of Oxford with immunogens from multiple pathogens such as influenza, tuberculosis, malaria, chikungunya, Zika, MERS-CoV, and Meningitis B. Over 360 healthy adult participants have received ChAdOx1-vectored vaccines in these studies. These vaccines demonstrated robust immunogenicity after a single dose and favourable safety profiles, with no vaccine-related serious adverse events (SAEs).
