Sorry, wasn’t meant to come across as a ‘dig’ at you or anyone else here... More the media and the way some have apparently reported it (although I should say I’ve seen nothing but sensible reporting with all numbers in it... And the first report I read gave me a direct link to the Oxford publication to read for myself.)Sorry yes, I should point out that I'm not trying to bash anything here. I'm simply corroborating the fact that the 70% number was published (without all the necessary context) by BBC during their breaking news.
Totally understand all of the actual numbers that you post, just also pointing out the dynamic nature of how these things are reported.
As a matter of fact, we’ll not know the full efficacy of any of the vaccines, at any dosage, until we’ve been using them a while. This is all about getting MHRA, FDA etc, approval. (And perhaps securing more orders for those planning to profit)
Edited to add:
Another positive is that strangely, the 62% efficacy was in the 2 ‘full’ doses weeks apart... The 90% efficacy was in the ‘half’ dose first, then a ‘full’ dose weeks later.
That has scientists scratching their heads trying to understand why a half dose, rather than a full dose, for the first round seems to be more effective. But it does mean we can vaccinate a lot more people under that regime, which is more good news.
