The study was not set up to look at any differences between the two. The Pfizer/BioNTech was available first so there is more data, but the Oxford/AstraZeneca was mostly used in the older age group. That rose to more than 85% after the second dose. The numbers were very small and there was uncertainty over their significance, said the researchers. These results are very encouraging and have given us great reasons to be optimistic for the future, said Professor Aziz Sheikh, director of the University of Edinburghs Usher Institute.
