Wired put out this piece the other day as well going over their shortcomings compared to Moderna and Pfizer, including dosing errors and leaving subgroups out of results as well as the more effective half dose possibly not going to anyone over 55. Though the author irked me a bit when he said that 3.5 x 10^10 is basically half the chosen dose of 5 × 10^10, but it's 140% of 2.5...
Regardless, looks like there may be shortcomings, but I haven't gone over much of the data yet other that reported in some news.

But for many of those arms in the UK trial—as well as everyone who got the vaccine in the Brazilian trial—publicly available trial information shows that the standard dose could be between 3.5 and 6.5 × 10^10 viral particles. The lower end of that range isn’t far off from a half-dose.
