For many AIDS activists, bone-marrow transplantation is...

Led by Dr. Peter Szilagyi, researchers at University of Rochester studied 414 children aged 5 and younger, who came down with...
...Rochester study, for example, happened to look at the effectiveness of a vaccine during two seasons in which the flu strain included in the vaccine was not well matched to the predominant circulating strain that was making people sick. That could explain the lack of protection among the vaccinees - the shot may have been protecting against the wrong flu proteins. Targeting the correct strain is a always a bit of a guessing game, however; researchers make their best scientifically based prediction as to which flu virus will be making the rounds in a coming season, but they often have...
Another reason for the flu shot's failure may have been the fact that certain forms of the vaccine are more effective than others in children. In this study, most of the children received the injected vaccine, but recent studies have shown that the nasal spray, known as FluMist, appears...
All of which means that, as this study's results show, we need to become more realistic when it comes to our expectations of the annual flu shot. There is no guarantee that it will work, but on a population level, odds are that it's better to get a...
