Abstract
Highly infectious rubella virus cDNA clones that are chimeric constructs of an infectious cDNA clone having a low specific infectivity and nucleic acid molecule fragments from a second rubella virus genome, wherein portions of the nucleotide sequence of the infectious cDNA clone having low specific infectivity have been replaced with the corresponding cDNA fragments derived from the second rubella virus genome.
