No. For something to be virulent it must be alive. Virulence usually refers to pathogens, like bacteria, viruses, and yeasts. But, pathogens, themselves, can create toxins by their metabolic activity. Still, however, the toxin itself wouldn't have the property of being virulent, only the "bug" would be.

Why do toxins need to be inactivated before being used in vaccines?

A toxin is a poisonous substance produced by living cells or organisms. Toxins produced by microorganism are important virulence determinants responsible for microbial pathogencity and/or evasion the host immune response. This will alter the human physiology when taken so to avoid the bad effect of toxin it is first inactivated and then used as vaccine which is known as toxoid.
