The Vaccination Battle

Before life can get back to normal, we need a vaccine and the Coronavirus jab battle seems to be settling down to two competing vaccines, the one from Pfizer/BioNTech and the one from Moderna who have both announced their early results following the phase three trials but how do the two compare?
Both the Pfizer and Moderna jabs use technology known as mRNA and the Pfizer vaccine found it offers 95% protection against the virus while Moderna's results indicate 94.5% effectiveness so no reall difference there.
The Pfizer version has to be kept at -70C to maintain optimal efficacy and has to be mixed with another liquid before it can be administered, whereas the Moderna vaccine can be stored at -20C which is equal to most household and medical appliances and no mixing is required making it easier to transport, store and administer.
That's a big plus for Moderna but it comes back down to earth with the price tag, rings us to the price tag. A single shot of Moderna's is £28 a dose, almost double the price of the £15 Pfizer version and when you are buying tens if millions, that matters.
The Moderna vacinne is one single shot but you would need two of the Pfizer vaccine 21 days apart but the clincher could be the time until it is ready to adminiser with Pfizer saying that pending health safety clearance from the Medicines and Healthcare products Regulatory Agency, they expect 10 million doses in doctors surgery's ready to enter arms by the end of this year, Moderna's vaccine would not be available in the UK until April/May.
Other vaccination trials are ongoing including one run by AstraZeneca and Oxford and as the UK government has already paid for 100 million doses of it, and they are saying they could start supplying early in the New Year, it will probably be that name on the bottle.
