Detection of persistent viremia by a live attenuated vaccine strain of the chikungunya virus in a blood donor

Abstract

We report here the case of a blood donor who tested positive for chikungunya RNA by nucleic acid testing introduced in Guadeloupe (a French island in the Caribbean) to prevent the transmission of arboviral infections by transfusion. The strain was isolated, and further investigations revealed the presence of the IXCHIQ live attenuated vaccine strain in blood 1 month after vaccination.

Limited tissue persistence confirms attenuation of live-attenuated chikungunya vaccine VLA1553 in non-human primates.
