The World Health Organization has confirmed that vaccines will not be available until the end of September-early October. Dr Margaret Chan, WHO director-general, confirmed that a vaccine will be available soon but not one that has been proven safe. Clinical trial data (that is needed before the vaccine can be distributed for general) use will not be available until another two to three months.
The vaccine still needs to be studied to find out if one or two doses are required to ensure immunity and to find out if there are any unforeseen side-effects.
The U.S may have as many as 160m doses of vaccine by October but they still don't know how far these doses will go. If more vaccine is required in each dose and two doses are required to ensure immunity then the 160m will only serve a fraction of the population.
However, swine flu is spreading faster in some countries than the experts predicted. So far it has infected more than a million people in the U.S and has killed more than 700 people globally.
