The Oxford/AstraZeneca vaccine has gone through rigorous testing, conducted on tens of thousands of participants from a diverse range of cultural settings.
The results of these trials have been reviewed in-depth by the Medicines and Healthcare products Regulatory Agency (the MHRA). In total, data for more than 23,000 trial participants has been analyzed.
The MHRA considered these results satisfactory and deemed the Oxford/AstraZeneca vaccine safe to use.
