Those things would only get more frequent and easier as the science progresses. I think the best shot to avoid a major disaster is to progress the science far and fast enough so that the consequences are not that severe. For example getting to a point where an "universal" antiviral agent (with an easy to update/modify "database" of targets) is possible.
