Donuel, the supposed low rate of efficacy of the AstraZenica vaccine is a misreading of the figures, which said that only 8% to 10% of the people in the tests of that vaccine were over 70.
I'd love to see a graph of the estimated efficacy of the different vaccines, but haven't found one yet; but I think the Pfizer one is supposed to have a better protective level than the AstraZenica one. Which makes it all the more annoying that (if I'm reading it right) the plan in Ireland appears to be to give the over-70s the AstraZenica vax.
What we're not realising is that the number of vaccines being produced is only what's possible for the factories - equivalent to a ukelele maker suddenly being told to fulfil the worldwide guitar demand.
Fair play to the Indians, who are giving away vaccine to Nepal, Bangladesh, Myanmar, Bhutan, Maldives and Seychelles.
