Can the varicella vaccine virus be transmitted (caught from a person who was vaccinated)?

Yes; however, transmission of the varicella vaccine virus is extremely rare. It has only been documented in healthy persons on three occasions out of the 21 million doses of vaccine distributed. All three cases resulted in mild disease without complications.

Available data suggest that the risk of vaccine virus transmission from healthy vaccinated persons is very low and occurs only if the vaccinated person has a rash. With the currently licensed single-antigen varicella vaccine, there have been 5 documented cases of transmission resulting in 6 secondary infections. Four of the cases of transmission occurred from healthy vaccinated children and the fifth occurred from an immunocompetent adolescent. The risk for transmission from vaccinees who are immunocompromised is thought to be higher.
