Is there heavy metals or mercury present?...

Question: 

Is there heavy metals or mercury present?

Answer: 

Vaccines contain small amounts of specific ingredients, all of which play necessary and important roles. The ingredients in vaccines have been carefully studied for a long time, and are safe in the small amounts used in vaccines. 

Aluminum is used in vaccines as an adjuvant. Adjuvants help improve the immune response to a vaccine (help the vaccine work better). Aluminum has been used safely in vaccines for over 70 years. It is one of the most common metals found in nature and is present in air, food, and water. In the first 6 months of life, infants receive more aluminum in their diet than from vaccines.  You can read more about vaccine safety and aluminum in vaccines here.

Thimerosal, a mercury-based preservative, is added to influenza vaccines produced in multi-dose vials. It is added to prevent bacterial growth.  It has been used safely in vaccines for over 80 years. Today, all routine childhood vaccines used in B.C. (except certain flu vaccines) are produced in single-dose vials and do not require thimerosal. You can read more about vaccine safety and thimerosal in vaccines here.
