Canadian scientists find way to boost vaccine production 100-fold

摘要

Vancouver, Canada - News research shows much smaller doses of vaccines than previously thought may be needed to combat pandemics of avian flu, tuberculosis and SARS, Canadian scientists told AFP. The research by a team at the University of British Columbian in Vancouver could mean more shots will be available. The team led by Wilfred Jefferies found standard doses could be reduced 100-fold and still be safe by adding an immune system booster commonly found in the human body. The study showed that when the immune system molecule was added at low doses to vaccines and injected into mice exposed to rabies, measles and smallpox, an immune response kicked in to protect them from the infections.
