China's Sinovac Biotech says that its low-dose bird flu vaccine proved effective in generating an immune response from 80 percent of the 120 volunteers taking part in the trial. The vaccine was developed by using a part of the whole H5N1 virus and combining it with an adjuvant that increases the potency of the therapy. Researchers have been scrambling to find a low-dose vaccine that might work against bird flu. A low-dose vaccine would make it possible to produce enough vaccines to vaccinate large numbers of people.
