A previously healthy boy who had received varicella vaccine developed herpes zoster with meningitis. The vaccine strain recovered from scabs of 3 skin lesions had the wild-type allele at position 108111, a vaccine marker never previously associated with vaccine-associated adverse events. The vaccine strain from cerebrospinal fluid also contained mutations never previously observed at vaccine-associated single nucleotide polymorphisms that would alter amino acid sequences in ORF54 and ORF59. The presence of distinct strains in skin lesions and cerebrospinal fluid indicate that>1 variant strain may reactivate to cause herpes zoster.
