In short, they stopped manufacture because the demand was not high enough to defend the lawsuits - even though science was on the side of the vaccine (though this is partially hindsight, it takes years to do good science much less time to file a lawsuit based on a correlation)

There is a new vaccine entering trials now. I hope it works, but only time will tell. (for all I know it may have failed trials - success will take more time, but failure can be quick and I wouldn't always find out)
