Two questions.

Was there ever a phase 2 trail for this Vaccine?

Is the full clinical trial data published?

There was an abbreviated Phase I/II and a Phase III. Not sure if the data were released.

The control arms were busted.

We touched upon this some time back. If you don't want to dig through the whole messy thread[1], I would recommend "Placebo-Controlled Trials of Covid-19 Vaccines — Why We Still Need Them"[2].
