I agree with that, Jim, but, and speaking just a layman, is it better to continue with a vaccine if, as claimed, it offers insufficient protection to achieve herd immunity when others which offer more are available? I appreciate that supply and costs are issues, but would anyone who had the choice accept 62% protection against this virus when others are getting 95%,?
As a matter of interest, does the Moderna vaccine carry the same onerous storage demands as the Pfizer one? If so I can see that there is a place for the Oxford AZ one in places which can't easily (or at all) comply with them.
Just interested with no particular point to make about the different choices.
