Since Thimerosal is not being used in routine childrens immunization shots in BC what preservative is being used?
Thimerosal is added to vaccines produced in multi-dose vials to prevent bacterial growth. Today, all routine childhood vaccines used in BC (with the exception of certain flu vaccines) are produced in single-dose vials and do not require thimerosal. However, certain vaccines given in childhood may contain other preservatives. You can find a list of contents in vaccines available in Canada here.
