60% efficiency which has been peer reviewed, is still as good as the flu vaccine, it can be stored in a normal fridge so will work better for distribution outside of major cities, and costs significantly less.
There are very few downsides, apart from not generating American news.
By my understanding, the quoted figure is what percentage of infection occurred in the control group.
60% efficacy is not going to get you to herd immunity, nor even any kind of immunity for the majority of people taking the vaccine.
Does this give more than a couple of weeks grace on lockdown, if the critical limiting factor is ICU beds?
You are more likely to get symptoms with the Oxford vaccine than an mRNA one, but no more likely to die or need hospital care

I believe Moderna is currently conducting a new trial to ascertain the transmission question. Until we know for sure, all the talk about herd immunity may be moot.
There is a proper study into this happening now, to see if the improved numbers are a real thing, or just a demonstration of the demographic.
The independent regulator was aware at every stage and recommended they continue with trying the half dose trial. [1](https://www.bbc.co.uk/news/health-55308216).
