There are no human approved coronavirus vaccines. There were a number of SARS vaccines that never finished clinical trials because SARS became pretty much a non-issue before they finished. There are also coronavirus vaccines approved for animals. Both of these things could potentially help with faster developing a vaccine for COVID-19.
Your black-and-white answer to this also has a pretty low probability. We may not find a vaccine, however we may find ways of treating the illness making the ICU less needed.
