The original strain - which is the basis of the vaccines - is not still out there. I mean that it is literally extinct.
With that being said, the current variants evolved from the original strain, and they still have many similarities. Getting a vaccine for the original strain will offer some protection against the current variants.

When a new strain infects others more effectively the older strains go extinct.
