Your Flu Season Toolkit
Fact: Influenza is a highly contagious virus that infects millions of Canadians every year. While most recover in about a week, up to 8,000 people, most of them young children and seniors, will die due to flu-related complications like pneumonia. Groups at risk for these serious complications include children under the age of two, seniors over the age of 65, and people with chronic conditions like diabetes, anemia, cancer, immune suppression, HIV and kidney disease.
You can protect yourself and those around you from influenza. Annual immunization is the safest and most effective way to prevent infection, to reduce the severity of your symptoms if you do get sick, and to keep from spreading the virus to others.
Fact: The flu vaccine cannot cause influenza because it does not contain any live virus. Flu vaccines only contain parts of the more common strands of flu viruses in order to prompt your immune system to create the right antibodies to fight off the real virus.
Mild side-effects can occur but rarely last more than 48 hours. Severe allergic reactions are possible but occur less than once in every million vaccinations in Canada and are treatable.
Fact: It is necessary to be immunized each fall to make sure your body forms antibodies against the most common strains of flu viruses circulating that year. Because the flu viruses are capable of changing from year to year, the vaccine is updated annually.
Each year, the World Health Organization (WHO) identifies three strains of the influenza virus that are predicted to be the most common and therefore will have the most impact on our health. Influenza vaccines are then developed based on these three viruses.
Fact: You may not be at risk of a serious illness but those around you may be more vulnerable. Even mild symptoms of influenza mean that you could be carrying it into the lives of your family, friends, coworkers and many others that you come in contact with during the day.
By getting immunized every fall, you will develop the antibodies to break down the flu virus in your system, lower your risk of catching the virus, reduce the severity of symptoms and avoid spreading the infection to those who are more vulnerable.
Fact: Immunization is the most effective means to reduce the impact of influenza.
As with any vaccine, the flu shot may not protect 100% of all susceptible individuals. However, with a good match to circulating strains, influenza vaccination prevents illness in approximately 70-90% of healthy children and adults.
You might still get influenza, but vaccinated people usually experience only mild symptoms. You could still get another strain of influenza that the vaccine was not designed to protect against.
Fact: The benefits of flu shots far outweigh the risks. Flu shots are especially important for children ages 6 to 23 months, who without immunization could be susceptible to serious flu complications. Flu vaccines do not contain live influenza virus and will not infect your children with the flu.
