title: Further data on the antigenic drift in subacute sclerosing panencephalitis (SSPE).
abstract: Serum and cerebrospinal fluid samples from 43 SSPE patients were investigated by double radial immunodiffusion against a measles virus cell pack antigen. The pattern of immune precipitates suggested that antigenic drift may be involved in the pathogeny of persistent virus infection.
