Perhaps the best Christmas cracker of a gift that any of us could have hoped for in this most difficult of years was the wonderful news that clever scientists around the world have developed an effective Covid-19 vaccine. It looks like a case of a bleak mid-winter for now and the war against Covid-19 isn’t yet over but at least we have hope. That’s why for this edition of our magazine, we decided on a nice, bright cheerful image for our front cover which we hope will lift your Christmas spirits just a tiny bit. Of course, there are still plenty of unknowns as to when and how the resulting vaccination programme might happen once regulatory approval is – hopefully – granted. There are big challenges still to be faced around the logistics of getting the world’s population vaccinated.
