Rabies is a dangerous virus transmitted throughbites from infected animals.
Oncesymptomsbegin, the disease is almost always fatal.
Fortunately, there is one option for the egg-allergic: Imovax, which is not cultured in chick embryos.
There’s one flu vaccineFlublok, made by Protein Sciences Corporationthat does not use chicken eggs during manufacturing.
However, studies showed that severe allergic reaction in people with egg allergies are very rare.
This vaccine is considered safe for people who have even severe egg allergies.

Yellow fever is the most potentially problematic of the three, and unfortunately, there’s no egg-free alternative.
