The vaccine currently available is the usual seasonal vaccine that includes protection against three strains of influenza. This does NOT include H1N1 2009 strain.
H1N1 2009 influenza vaccine is anticipated to be available in November. It will be available in injectable and nasal forms. The manufacturing process is identical to current seasonal influenza vaccine. It is not an "experimental" vaccine. It is recommended for children over 6 months old and will be most important for children under age 5 and those with chronic health conditions that put them at higher risk for complications from influenza. Dosing and schedule has not been finalized but will likely closely mirror current seasonal influenza vaccine schedule.
