late onset allergies can occur at any time. I'd highly doubt the flu shot caused egg allergies. I'd bet late onset egg allergies caused the sickness from the shot. Could be the other way around but that seems strange.
All flu vaccines use immunologic adjuvant's to increase efficacy. Egg embryo's are used in the process to host the flu culture, the connection here is not at all implausible, and more common than is reported.
