When is the HiB vaccine contraindicated?
Hypersensitivity to any component of the vaccine, including diptheria toxoid and thimerosal in the multi-dose presentation. Vaccine components capable of causing adverse reactions: phenol, bacterial polysaccharides, thimerosal (Travel Medicine Advisor). (Note: There is currently, as of 1999, a move toward replacing thimerosal in vaccines, so the reference to thimerosal here may shortly be out of date.
