GSK / Fluarix
Fluarix is an influenza vaccine that contains inactivated fragments from three different strains of the virus that causes influenza (flu). The vaccine works by provoking the body's immune response, without causing the disease.
When the body is exposed to foreign organisms, the immune system produces antibodies. These antibodies are specific to the infecting agent and their first function is to help the body recognise and kill the foreign organisms. The antibodies formed remain in the body and recognise any future attack with the same organism. This forms what is known as immunity, as it enables the body to launch a swift attack against the invading organism, before it can cause disease.
Protection against many infections can be provided artificially by means of vaccines derived from altered forms of infecting organisms. These vaccines stimulate the immune system to produce antibodies in the same way as genuine infection, without actually causing the disease. As the organisms stimulate the production of a specific type of antibody, a different vaccine must be used for each disease.
Influenza vaccines provide immunity against infection with the influenza virus and therefore prevent flu. The flu virus, however, is constantly changing its structure (mutating). This means that each year a different vaccine containing different strains of the virus is required. This vaccine contains the strains of influenza that have been identified by the World Health Organisation and the EU as being prevalent for the 2006 to 2007 season.
The influenza vaccine is recommended for people who run an increased risk of complications if they get flu. These risk groups include people aged over 65 years, people living in long-stay residential care homes, and those older than six months of age with any of the following: chronic lung disease, including asthma; chronic kidney disease; chronic heart disease; diabetes; HIV infection; or an underactive immune system, either due to disease or treatment. Carers and healthcare workers who are involved in direct patient care are also advised to have the vaccine.
Influenza vaccination should be repeated each year with the appropriate, approved vaccine. Protection usually occurs within two to three weeks after vaccination, and the duration of the immunity varies, but usually lasts 6 to 12 months. Children who have not previously been vaccinated against influenza should receive a second dose following an interval of at least four weeks after their first vaccination.
The influenza vaccine will only protect against flu caused by the influenza virus. It will not prevent flu-like illnesses caused by other germs.
