No H1N1 vaccine before September, WHO says

GENEVA, June 11 (Reuters) - Different regulatory authorities need to work together to speed registration of a safe H1N1 flu vaccine, which will not be available before September, WHO Director-General Margaret Chan said on Thursday.

She also told a news conference the virus did not appear to be mutating, something that could make the infection even more difficult to fight.

“The virus is pretty stable,” she said after the World Health Organisation raised its pandemic alert to phase 6 to indicate a flu pandemic was under way.

Drugmakers have obtained the new influenza A (H1N1) seed virus in the past two weeks, enabling them to begin the production process by growing the virus in eggs.

Company officials said on Wednesday that they were on track to have a vaccine against the new strain ready for the northern hemisphere autumn. (Reporting by Laura MacInnis, Jonathan Lynn and Stephanie Nebehay, Writing by Michael Kahn, Editing by Alison Williams)
