Well 98% not effective. Old news here but the new readers on this forum might take something away from it.
Remember swine flu is a variant of H1n1. This article is fact.
''So far this season, it is far higher: more than 98% (321 of 325) of H1N1 isolates tested by the Centers for Disease Control and Prevention (CDC) were resistant to the drug.
None of the H1N1 isolates have shown resistance to zanamivir (Relenza), the other flu drug in the neuraminidase inhibitor class. H1N1 is one of three flu subtypes that circulate each season, along with A/H3N2 and influenza B.
Because of the spread of resistance, the CDC in December changed its recommendations on antiviral treatment for flu. For patients suspected of having influenza A, the CDC recommended using zanamivir or a combination of oseltamivir and rimantadine (an older flu drug in a different class) instead of oseltamivir alone.
