UK pharma giant AstraZeneca, which is developing a Covid vaccine in partnership with University of Oxford, has said that the vaccine development is progressing well. The AstraZeneca-Oxford vaccine is already in large-scale human trials. The vaccine candidate leading the global race after results from early-stage human trials showed it was safe and produced an immune response. “The vaccine development is progressing well. We have had good data so far. We need to show the efficacy in the clinical programme, but so far, so good,” chief executive Pascal Soriot said on Thursday.
