Does this mean we're out of options to get humans to the ISS?

SLS is nowhere near, Dragon is coming next year. Soyuz has been extremely reliable but with two incidents they'll surely ground flights for a while.

Is there any other option?

SLS will likely never service the ISS if it flies- it is designed for deep space missions and constructing the Deep Space Gateway station in cislunar orbit. Orion also is not ready for use, and even if it was it has only been flown on the Delta IV which is not human-rated.

One other option is the Boeing CST-100, however after its engine test failure this last summer it likely won't fly this year either. But like Dragon it is thought to be almost ready.

Perhaps this means the priority of SpaceX manned flights will be pushed up. We could end up seeing this much sooner.

They already said they won't rush anything because that's just as dangerous as using the Soyuz again before figuring out the reason for the failure. That said this does open up a visiting vehicle slot that Dragon could use for their unmanned test flight. That'd only push it up about a month though compared to their current estimate and would require SpaceX to be ready to launch earlier than planned.
