2001 JAN 17 - (NewsRx.com & NewsRx.net) -- Researchers at the Oswaldo Cruz Institute in Brazil think new flavivirus vaccines may result from recombinant DNA technology.

"A live attenuated virus is used as a cost-effective, safe, and efficacious vaccine against yellow fever, but no other live flavivirus vaccines have been licensed," noted M.C. Bonaldo and colleagues ("The yellow fever 17D vaccine virus as a vector for the expression of foreign proteins: Development of new live flavivirus vaccines," Mem Inst Oswaldo Cruz, 2000;95 Suppl 1:215-23).

They propose using "cDNAs encompassing the whole viral genome to generate infectious RNA after in vitro transcription." Genetic mapping of viral functions could be accomplished via this approach, they said, as well as "the design of viral mutants with ...
