    Allergic reactions to vaccinations can occur, but are very rare. By far the most common type are allergic reactions to egg, as an egg protein makes up part of the measles, mumps, and yellow fever vaccines. If you are not allergic to eggs, these vaccines shouldn't cause problems for you. If you are allergic to eggs, tell your doctor. Occasionally, too, the antibiotics neomycin or streptomycin are included in various vaccines. If you are allergic to either of these antibiotics, alert your doctor just to make sure you receive an antibiotic-free vaccine. No vaccines currently contain penicillin, so if you are allergic to penicillin, you have no reason to avoid getting vaccinated.
