* WHO expert set to give briefing on flu vaccine Monday * H1N1-resistant cases have raised interest in jab (updates with WHO spokeswoman saying briefing likely on Monday) GENEVA, July 10 (Reuters) - The World Health Organisation (WHO) will probably hold a media briefing on Monday to issue guidance about the need for a H1N1 influenza jab, a WHO spokeswoman said on Friday. "The recommendations are still in the process of being developed," Fadela Chaib told a news briefing in Geneva, where the United Nations agency is based. "The press conference will probably be on Monday," she later told Reuters. Marie-Paule Kieny, WHO director of the Initiative for Vaccine Research, would give a news briefing once the recommendations emerging from the closed-door WHO meeting on Tuesday are approved by WHO Director-General Margaret Chan. The WHO raised its influenza pandemic alert to the highest level on June 11 in response to the worldwide spread of H1N1, a newly discovered virus strain commonly known as swine flu. Vaccine makers such as Sanofi-Aventis <SASY.PA>, Novartis <NOVN.VX>, Baxter <BAX.N>, GlaxoSmithKline <GSK.L> and Solvay <SOLB.BR> are seeking WHO guidance about whether to ramp up production of jabs for the strain, to keep making seasonal flu vaccines, or to produce a combination. The discovery of three isolated cases of H1N1 flu in Denmark, Japan and Hong Kong that resisted treatment with the anti-viral drug Tamiflu, made by Roche <ROG.VX> and Gilead <GILD.O>, has raised interest in a jab to prevent infection. The WHO said earlier this week that Tamiflu-resistant H1N1 flu does not appear to be spreading in a sustained or worrisome way. All patients with the resistant variety have recovered fully, and their viruses were sensitive to treatment with the other anti-viral recommended by the WHO, the inhaled drug Relenza made by Glaxo under license from Biota <BTA.AX>.
