Will a new mutated virus come along and, if so, will present vaccines work against it? Can we stop using the vaccine or do we have to go on forever? These are just some of the questions now surfacing in the wake of the recent epidemic

Now that circovirus vaccines have been such a resounding success, where do we go with circovirus (PCV2) from now on? What else does it have in store for us?
For instance, there is talk that another new mutated PCV2 virus may come along and that the current vaccines might no longer provide protection against this “new” strain. This, of course, is purely speculative.
