It seems like they tested for antibodies, but this article makes no mention of challenges to the real virus.
It's important to remember that vaccines for previous coronaviruses (SARS/MERS) had reports of generating anitbodies, but also causing immunopathic responses or immune enhancement syndrome:

>Is it safe?
It's really really to early to say yes or no, and the fact that the article tries to make a claim either way, is worrying. Vaccines for new families of viruses traditionally take years or decades to develop. We still don't have vaccines for retroviruses like HIV/Herpes (and it may not be possible due to the nature of those viruses).
I've had all my vaccinations; I'm not an anti-vaxer. But I do have concerns on trying to push out any novel vaccine in less than two years without adequate testing.
Although this virus has killed many, the risk factor for it is nowhere near high enough to warrant an emergency vaccine. There are trials underway for inhaled steroids that look very promising, and there's a good chance this virus will burn out in our population long before a truly safe vaccine comes to market.
Having a viable treatment option seems much more valuable and safer than vaccinations in this particular case.
