Final answer:

The Hepatitis B vaccine is contraindicated for individuals with an allergy to yeast, as the vaccine is produced using yeast cells.

Step-by-step explanation:

The Hepatitis B vaccine is specifically contraindicated for individuals with a history of anaphylaxis to yeast. This is because the vaccine is produced using recombinant DNA technology where the gene for the hepatitis B virus surface antigen (HBsAg) is inserted into the genome of the yeast, Saccharomyces cerevisiae. The yeast cells are then grown, and the HBsAg is harvested and purified for use in the vaccine. As the vaccine contains yeast proteins, individuals with an allergy to yeast could suffer a severe allergic reaction.
