A team at Bristol University has used recently developed techniques to validate that the vaccine accurately follows the genetic instructions programmed into it by the Oxford team.

The AstraZeneca Oxford COVID-19 vaccine (ChAdOx1 nCoV-19 and also known as AZD1222) now undergoing Phase III clinical trials, has already undergone rigorous testing to ensure the highest standards of quality and safety. Now a team at Bristol University has used recently developed techniques to further validate that the vaccine accurately follows the genetic instructions programmed into it by the Oxford team. This novel analysis provides even greater clarity and detail about how the vaccine successfully provokes a strong immune response. 

The findings, led by scientists at the University of Bristol and published on the pre-print server ResearchSquare, represent the most in-depth analysis of any of the COVID-19 vaccine candidates, going significantly above and beyond any regulatory requirements anywhere in the world.

Work on the vaccine, developed by researchers at the University of Oxford’s Jenner Institute and Oxford Vaccine Group, began in January 2020. Now undergoing Phase III clinical trials by the University of Oxford and AstraZeneca, the Bristol researchers’ focus was to assess how often and how accurately the vaccine is copying and using the genetic instructions provided by the Oxford team. These instructions detail how to make the spike protein from the coronavirus, SARS-CoV-2 that causes COVID-19.
