Experts say Pfizer/BioNTech product faces more logistical challenges and obstacles
The Oxford vaccine is likely to be the first Covid jab that large numbers of Britons receive, despite Pfizer’s candidate already being analysed by the medicines regulators, experts say.
The fact that the Oxford vaccine can be kept in normal fridges, whereas Pfizer’s product has to be stored at -75C , may see it enter widespread usage ahead of the latter.
