gsk vaccine

As I said before great news but read this to put it in context. vaccines are not antivirals



''Creating a prototype pandemic vaccine, however, does not guarantee that countries will be protected in the event of a flu pandemic. ``This vaccine will only give protection against this particular H5N1 strain and possibly other H5N1 strains,'' said Osterhaus. Thus, if the next influenza pandemic is sparked by a subtype other than H5, much of this vaccine may prove of little use.

``It's a risk judgment for those potentially purchasing vaccine,'' said Dr. Angus Nicoll, influenza coordinator at the European Center for Disease Prevention and Control.

Because it is impossible to predict which influenza strain will spark the next pandemic, it is equally impossible to produce a vaccine that will be completely effective.''
