World Health Organization advisers will announce the make-up of this coming year’s seasonal flu vaccine on Thursday.
Flu vaccine makers anxiously await the decision, scheduled to be announced at 5 a.m. EST/1000 GMT, because they need this guidance to start formulating vaccines for the Northern Hemisphere’s fall vaccine mix.
The decision is more complicated this year because of the pandemic of H1N1 swine flu. Although the pandemic is on the wane, the virus is still infecting and killing people.
Other strains of flu are still circulating but at far lower levels than usually seen in February.
