Don’t actually blame them in this case. It’s a good looking result, but it’s using the same new approach as the Pfizer drug, and Moderna has no track record of delivery, great looking pipeline but no marketed products as yet - makes sense to go with Pfizer, Moderna is a fairly risky bet, and it’s not clear to me how they will manufacture hundreds of millions of doses without buddying up with one of the big companies. A risky looking bet when you are spreading your cash over a very large number of potential vaccines. Of course, you look a tit when it doesn’t come off, which is why I suppose the government has bought 5 million doses (enough for 2.5 million people).US drug company Moderna has come up with a Covid vaccine that they claim to be 95% effective. Unfortunately the UK didn't place any advance orders with Moderna. The EU Commission has options for 160m doses, but our government - presumably filled with Brexit hubris - chose not to take part in the EU scheme.
The RNa approach looks to be bringing spectacular results, if the Oxford vaccine works I’m pretty sure it will be much less effective on paper. On a population level it doesn’t really matter, the idea is just to make it hard for the virus to spread, and to keep the symptoms mild if it does.
