AS we finally reach the end of this ghastly year, it is natural to search for signs that 2021 will be healthier, happier and more economically prosperous than the months of misery we have had to endure since coronavirus began to dominate our daily reality. The roll-out of vaccines offers the brightest hope of a return to normality, and there was huge news on this front yesterday, when the Oxford-AstraZeneca jab was given the green light for use by the UK Medicines and Healthcare products Regulatory Agency. While numerous other vaccines have either been approved for use or are under development, the Oxford inoculation has been hailed as a “game changer”, given that it will be priced significantly cheaper, and distributed and stored more easily than the Pfizer-BioNTech vaccine currently in use.
