Scroll to 03:50. French virologist speaks of a disastrous overreaction of the immune system about 8-10 days into the infection. The virus has abated but the immune system is now attacking the body. So 2 phases: viral and immunological.

The term that was used in reference to the failure of the initial SARS vaccine was "cytokine storm" and I think that is what the virologist in the video is referring to. The vaccine failed due to all the test animals dying when they were infected with SARS after being immunized with the vaccine.

This brings up the question of what can happen when you get the novel Coronavirus over and over. I am also skeptical of vaccines for old people who do not have any immune system left to stimulate. Other therapies will be needed. This pestilence is worse than 1918, which also produced an overreaction of the immune system.
