Egg allergy and MMR, what's the deal?

[higerprimate2]

All right, First Aid Step 2 (page 390 8th edition) says off you have a sever egg allergy then MMR is contraindicated. MTB Step (page 342) goes out of its way to state that a "documented" egg allergy is NOT a CI for the MMR vaccine. Is this some BS with the wording? What should I answer if this comes up on the test?

The contraindications for MMR that I have are:
1) moderate or severe febrile illness
2) anaphylaxis to neomycin or gelatin (or to prior vaccine)
3) severe immunosuppressed states
4) thrombocytopenia following 1st dose of MMR
5) recent immunoglobulin treatment
6) pregnancy.

This is from UWorld (Step 3). So, I am pretty sure that even with an egg allergy, you can give the MMR vaccine.

They're not really going to elaborate on the severity of the person's allergy. MMR has been documented as safe to administer to individuals with egg allergy, it's grown in chick embryo cells. The contraindications mentioned by futuredoctor10 are on the dot.

The MMR vaccine is as safe as any other vaccine, and children with an allergy to eggs must not have their vaccinations delayed.
