They didn't go exactly the same testing phases; the serialization doesn't work like that, you cannot replace time with parallelism (the 9 pregnant women is a suitable analogy).

So, the timeline is:

- Corminaty; currently doing phases 3 and 4; assumed end is december 2023;

- Spikewax: currently doing phases 3 and 4; assumed end is december 2022;

- Vaxzevria: currently doing phases 3 and 4; assumed end is second quarter 2022;

- Janssen: still doing phases 1/2a, 2a, 3; assumed end december 2023;
