VATI Pediatrics Practice Exam

The vaccine that is contraindicated for individuals with a severe allergy to neomycin is the measles, mumps, and rubella (MMR) vaccine. This is because the MMR vaccine contains neomycin as a stabilizer. For individuals with a documented severe allergic reaction to neomycin, receiving the MMR vaccine poses a risk of anaphylactic reaction, which is why it should be avoided.

While other vaccines listed, such as the hepatitis B and influenza vaccines, do not contain neomycin in their formulations and can generally be administered safely to individuals with a neomycin allergy, the varicella vaccine also presents a concern. However, the MMR specifically highlights the presence of neomycin and its associated risk in allergic individuals, making it a clearer contraindication.

In summary, individuals with a severe allergy to neomycin should refrain from receiving the MMR vaccine due to the potential for severe allergic reactions.
