massive switch to relenza by govt, page-2

From that article if you cant read. PS sorry port I saw you posted this.



''Both drugs work by blocking a protein on the surface of influenza particles called neuraminidase which allows the virus to spread from infected cells to other cells in the body. Scientists say mutant H1N1 viruses have evolved to evade Tamiflu through a single mutation in the neuraminidase that prevents the medicine from clinging to the viral protein, thereby enabling the pathogen to spread. Relenza isn’t affected by the mutation.''

The swine flu is related to H1N1. Enough said.
