WHO decision on flu vaccine strains expected next week
Influenza experts will meet from Feb 14 to 19 at the World Health Organization (WHO) headquarters in Geneva to decide which flu strains to recommend for use in vaccines for the Northern Hemisphere's 2010-11 flu season, according to the US Centers for Disease Control and Prevention (CDC). In a recent question-and-answer statement, the CDC said the vaccine, as in past years, is likely to be trivalent (covering three strains), "although committee members may consider other options." In line with a WHO recommendation made last September, the seasonal vaccine that Australia will use for its upcoming winter flu season includes the pandemic H1N1 virus along with an H3N2 strain and an influenza B strain. The US Food and Drug Adminstration's vaccine advisory committee will meet Feb 22 to consider the WHO's vaccine recommendation, the CDC said. The panel normally follows the WHO's lead.
