H1N1 vaccines should offer broad protection even if the pandemic flu virus mutates as it spreads, a top World Health Organization expert related on Wednesday.

Marie-Paule Kieny, director of the WHO’s vaccine research program, asserted that health employees should get immunized first when the shots start to be distributed, as early as this month. “The agreement is that the first doses should be available to governments to be used in September,” she claimed.

The U.S. Center for Disease Control and Prevention declared last week that it was doubtful the vaccines would be available before October. About thirty candidate vaccines are being worked on in the frenzy to combat influenza strain that first appeared in Mexico and the U. S. and then moved around the planet. “No nations will have vaccine for everybody from the first day it is available for use,” Kieny informed the WHO Circular , a publication of the United Countries agency.

“No nations will have vaccine for everybody from the 1st day it is available for use,” Kieny informed the WHO Circular , a publication of the United States agency. The chemical industry will used tiered pricing for the states purchasing H1N1 vaccines, charging rich states $10 to $20 per dose, middle-income nations half that amount and low income nations half that again, according to Kieny. “These are ballpark figures but this is the order of magnitude,” she revealed. Research on shots developed replying to H5N1 bird influenza, which is more lethal than the pandemic variety but spreads a lot less simply between humans, has helped vaccine manufacturers develop safe H1N1 shots quickly, according to Kieny. US analysts declared this week that H1N1 appeared improbable to mix with other circulating flu viruses into a “superbug.”

Kieny asserted the new strain would need to mutate in a major way for the vaccines in the works to be rendered ineffectual. “Although the virus can mutate, we are hoping that there’ll be enough cross-protection thru recognition of the new virus. But if the virus changes too much, we’ll need new vaccines,” she informed the WHO Circular .

The WHO foresees a 3rd of the planet’s population will finally become infected with H1N1, commonly called swine influenza. So far, at least 2,185 people have died of it and millions of people have been infected.
