Which of the following vaccines has a contraindication associated with neomycin allergy?

The MMR vaccine, which protects against measles, mumps, and rubella, contains live attenuated viruses and also includes neomycin as a stabilizer. Neomycin is an antibiotic that can cause allergic reactions in some individuals. Therefore, if a person has a documented allergy to neomycin, it is contraindicated for them to receive the MMR vaccine due to the risk of an allergic reaction, which may lead to serious health issues.

While the varicella vaccine also contains neomycin, the specific reference to the MMR vaccine often underscores its significance in pediatric vaccinations and the potential for allergic reactions linked to neomycin. The other vaccines listed, such as the DTP vaccine and the hepatitis B vaccine, do not have this particular contraindication regarding neomycin. Thus, recognizing the connection between neomycin and the MMR vaccine is crucial in ensuring patient safety and compliance with guidelines regarding vaccine administration.
