We have a child who received multiple vaccines, some of which contained gelatin and neomycin. We suspect that the child may have reacted to the gelatin or neomycin. What is the protocol that I should use to skin test to neomycin? Thank you for your help.


Thank you for your inquiry.

You will find a skin test protocol for testing to neomycin in the article referenced below from the Annals of Allergy, Asthma, and Immunology.
