This table includes not only vaccine ingredients (e.g., adjuvants and preservatives), but also substances used during the manufacturing process, including vaccine-production media, that are removed from the final product and present only in trace quantities.

In addition to the substances listed, most vaccines contain Sodium Chloride (table salt).
