Against bird's flu ? And does it help somehow against bird's flu if it is not a vaccine? Can u guarantee u'll survive if u use it ? Also scientists write that bird's flu doesn't pass from a human to a human, only from a bird to a human, this is what is regarding N5H1. Then why all the word is waiting that somehow this virus will change ( so called mutation) and then already a human will be able infect another people. My question why not to wait such a change from other kind of viruses, and why it is expected just from bird's flu ? And by the way why were these expectations happened now, not in 1961 when N5H1 was found ?
