How does this medication work? What will it do for me?
This medication belongs to a group of medications known as vaccines. It is used to prevent influenza (the flu). Influenza is a common viral illness caused by 2 types of virus: influenza A and influenza B.
Each year, different strains (new, slightly different versions of the virus) appear. Scientists predict which strains will be most likely for the coming year, and then these strains are used to make up the year's influenza vaccine. Each year's influenza vaccine contains 3 virus strains that are likely to circulate in Canada in the coming winter. The vaccine only provides protection against the strains of flu virus used to prepare the vaccine.
The vaccine increases a person's defenses against the influenza virus. It works by introducing very small amounts of viral components (parts) into the body. These components are enough to stimulate the production of antibodies (cells designed to attack that particular virus), which will remain in the body ready to attack that same virus in the future. The vaccine is used to prevent influenza for people over 6 months of age who want to reduce their chances of getting the flu.
The National Advisory Committee on Immunization (NACI) recommends annual vaccination for:
- any healthy person wanting protection from influenza
- children aged 6 months to 18 years who are being treated with acetylsalicylic acid (ASA) for long periods of time
- health care workers
- healthy children aged 6 to 23 months
- healthy pregnant women
- household contacts (including children) of people at high risk who cannot be vaccinated or who may not respond to vaccination
- people at high risk of complications of influenza that are travelling to areas where influenza is likely circulating
- people over 65 years of age
- people who have HIV
- people with certain chronic health conditions, such as asthma, heart disease, diabetes, cancer, cystic fibrosis, anemia, or kidney disease
- residents of nursing homes or chronic care facilities
- people who provide essential community services
- people who provide services within relatively closed settings to persons at high risk (e.g., crew on a ship)
