Final Answer:
The vaccine contains trace amounts of neomycin, and administering it could trigger an adverse reaction in individuals with such allergies. Thus, the correct answer is option (A) MMR vaccine.
Step-by-step explanation:
The MMR vaccine, which protects against measles, mumps, and rubella, contains a trace amount of neomycin, an antibiotic. Neomycin is used in the manufacturing process of the vaccine to prevent bacterial contamination.
Individuals with a known allergy to neomycin may experience an adverse reaction if exposed to this component. Therefore, if a child has a documented neomycin allergy, it is recommended to avoid administering the MMR vaccine to prevent potential allergic reactions.
Thus, the correct answer is option (A) MMR vaccine.
