Immunisation: Influenza

The 2011 seasonal influenza vaccine contains pandemic A(H1N1), seasonal A(H3N2) and B strains. While these are the same strains used in the 2010 influenza vaccine, Australians are still encouraged to receive this year’s vaccine as immunity lasts only one year. Healthcare workers are amongst the groups targeted this year for immunisation. The Government Web site on immunisation has good information  and includes commonly asked questions along with links to other relevant sites.

Under the National Immunisation Program,  the influenza vaccine is funded for the following groups:

• All persons aged 65 years and over;
• All Aboriginal and Torres Strait Islander people aged 15 years and over;
