Swine flu vaccine manufacturers will start delivering vaccines in September

World Health Organization said on Thursday that Swine flu vaccine manufacturers will start delivering the vaccines in September for the first batch.

A number of drug makers have started testing swine flu vaccine in humans, and that early safety results should be offered next month, clearing the means for its use. Kieny also insisted that speeding the vaccine to the market will not support its safety, Marie-Paule Kieny, WHO's vaccine director, said.

WHO has recommended that first batch of the vaccines should be given to health care workers, pregnant women and people with health problems.

Kieny said WHO expects to see reports of side effects once the vaccine is given to millions of people, but that deadly side effects will be rare.

She said the agency would work with country officials to detect any sign the vaccine might cause more worrying side effects, like Guillain Barre syndrome, a temporary paralysis disorder reported by hundreds of people after the U.S.'s disastrous 1976 immunization campaign against another variant of swine flu.
