| | US scientists resurrect deadly 1918 flu |
 | | By replacing the genes for either the 1918 virus’s surface protein, haemagglutinin (HA), or for its polymerase complex, with genes from a tamer, related flu, the team showed that both contribute to its deadliness, with the HA especially damaging for lungs. |
 | | But, says Taubenberger, the 1918 sequences are already helping in another way: they prove that a bird flu can go pandemic without combining with a human flu, and suggest which mutations it needs. |
 | | But while a specific 1918 vaccine is possible, none is now available, and Tumpey says no vaccine has been tested against the resurrected virus. |
