On reading your link, I found it rather difficult to correlate what was going on. I'm sure it makes a lot of sense to people who work in immunology.
The most advanced are not Covid-19, but tests to see if BCG really does limit the worst effects of Covid-19. It will not stop people getting it, nor them spreading it.
The Chinese moderna vaccene may have passed phase 1 testing, but they are having issues getting into phase 2 because of a lack of Chinese infections.
The other Chinese vaccene only reached phase 1/2 approval at the end of April, but is listed as phase 2.
The third Chinese vaccene is registered for trial but no approval date.
The Oxford vaccene has started a phase 1/2 trial and has half the number of phase 2 tests than the Chinese vaccene, but one assumes 5 times the phase 1. Immediately after the article states that they have started testing on 1,100 people. Which is twice the number stated further up the paragraph. Perhaps that is the 1/2 split.
Invio, Pfizer and sinovac vaccene are just beginning to start testing. They are phase 1, with some faster phase 1/2 trials just ramping up. None of these tests are of the size of the more advanced tests.
The rest are pre clinical so of little interest until they get approval for testing.
What does that mean for the layman?
They are still looking at using bcg to save lives and might get there first, if proven. However there are three vaccene which may come to rapid approval for delivery by year end. However the Oxford one is the most likely to be able to produce rapid valid results due to the ongoing volume of cases in the UK. China will need to find a partner country to test. If they are clever they will approach Russia.
