Canadian vaccines

 Why do Canadian parents repeatedly say their vaccines are mercury free and they say it with absolute. 
So where do they get this from?  

According to Health Canada
Currently, the only thimerosal-containing vaccine in routine use in the infant immunization schedules of some Canadian jurisdictions is the hepatitis B vaccine.

 This does not mean that all thimerosal-containing vaccines have been eliminated in Canada. A number of other thimerosal-containing vaccines are licensed that are used in special circumstances, that could continue to expose infants < 6 months of age to ethylmercury.  
These include some single antigen acellular pertussis and conjugate H. influenzae vaccines, diphtheria-tetanus, and diphtheria- tetanus-acellular pertussis combination vaccines, all of which contain thimerosal in a concentration of 0.01%, and represent an exposure of 25 µg ethylmercury per 0.5 mL dose(11).  
Thimerosal- containing hepatitis B vaccine continues to be used in some Canadian jurisdictions to protect high risk infants born to chronic hepatitis B infected mothers. Influenza vaccines that are licensed in Canada also contain 0.01% thimerosal but are not recommended or used in infants < 6 months of age because of lack of effectiveness early in life.

 Here are the thimerosal concentrations in the Hep B vaxes licensed for use in Canada: 
Engerix BTM [Glaxo Smithkline] and Recombivax BTM [Merck Frosst Canada]) have been available in Canada since these programs were initiated, containing thimerosal at a concentration of 0.005% or 50 µg/mL.  
A regular infant dose of 0.5 mL Engerix BTM contains 12.5 µg of ethylmercury, while a regular infant dose of 0.25 mL of Recombivax BTM contains 6.25 µg.
Health Canada also states: 
There is no legitimate safety reason to avoid the use of thimerosal-containing products for children or older individuals, including pregnant women.
