Egg allergy sufferers must avoid vaccines
Egg allergy is the most common food allergy in children, and several ordinary vaccines such as MMR are made in eggs and consequently contain microscopic remains of egg. So, there is a theoretical risk that the vaccines could cause an allergic reaction. However, the quantity of egg protein is so small that allergic children can easily get their vaccinations anyway. In most cases, the kids need to stay in the medical centre for observation for 30 minutes. Only if a child has previously reacted severely to eggs, will doctors choose to give the vaccination in a hospital, although no direct connection has been proved between severe allergic reactions and the content of egg in vaccines. Fatal reactions only occur 1.2 times per 1 million doses, and in most cases, they happen to patients who do not suffer from egg allergy.
