An experiment by a research team at Beijing University was hailed as “revolutionary” in the field in a paper published in the latest issue of Science magazine on Friday. The live virus used in the vaccine used by the researchers had its genetic code tweaked to disable the viral strains’ self-replication mechanism. But it was kept fully infectious to allow the host animal cells to generate immunity. Using live viruses in their fully infectious form was considered taboo, as viruses spread rapidly. Vaccines sold and used widely today generally contain either dead or weakened forms of viruses. The animals infected with virus were cured after receiving the injection, according to the paper. This breakthrough promises to simplify the process of producing vaccines, which may help scientists develop effective vaccines or even cures for various viruses – such bird flu, SARS, Ebola and HIV – within weeks of an outbreak.
