Posted this recently but the problem with the Oxford announcement is that is has provided unrealistic targets for the general public and slightly misleading in terms of using the phrase
'a vaccine will be ready by...' . We possibly will get a vaccine (hopefully one that ticks all boxes) at some stage but not in any meaningful time frame that helps us look at a government/global policy in the next two years at least. The problem is if
hope for a vaccine becomes the only strategy we are pursuing whilst running traffic light systems on infection rates for lockdown/loosening then we are screwed as its simply not sustainable beyond a six month period for obvious reasons.
Anti virals have to be the first line of focus and all our energy and we are going to be looking at possibly a cocktail of these drugs. History of the HIV anti viral development took us decades to get to a single silver bullet option to make the virus non detectable after using various combinations previously. I am hopeful in this sector but again time is the enemy, so I suspect we are tip toeing into Herd Immunity at different speeds around the world with the hope we get our frontlines primed and our testing systems coordinated to reduce the mortality rate whilst crawling our way to the 80% figure (again assuming that's the figure with our fingers crossed on the level of protectiveness and durability our antibodies will give us)
Link to Oxford trials on vaccine time lines etc which is a good read and just one article of many but is reflective of the general consensus in the scientific community on this topic.

Just one extract:-
That in itself would be a remarkable achievement. The 2013 study found that between 1998 and 2009, the average time taken to develop a vaccine was 10.7 years. It is possible to speed this up to some extent – since then, an Ebola vaccine has become the fastest-developed vaccine ever, being produced in just five years.
