Introduction
Flu vaccines are primarily cultivated in chicken embryos, so they may contain trace amounts of egg protein. However, for most individuals with egg allergies, the amount of egg protein present in the flu vaccine is extremely low and typically insufficient to trigger a severe allergic reaction. In addition, there are various manufacturing processes for flu vaccines, some of which can reduce the risk of allergic reactions for individuals with egg allergies.
Generally speaking, people with egg allergies can usually receive the flu vaccine. The detailed explanation is as follows:
Flu vaccines are primarily cultivated in chicken embryos, so they may contain trace amounts of egg protein. However, for most individuals with egg allergies, the amount of egg protein in the flu vaccine is extremely low and generally insufficient to trigger a severe allergic reaction. Additionally, flu vaccines are produced using various manufacturing processes, some of which can reduce the risk of allergic reactions for individuals with egg allergies.
If the egg allergy is very severe and has previously caused a serious allergic reaction, there may be some risk in receiving the flu vaccine. In such cases, doctors may recommend alternative preventive measures, such as avoiding exposure to the influenza virus. At the same time, doctors will ask about the type and severity of allergic symptoms to determine whether vaccination is appropriate.
Prior to vaccination, you should inform the doctor about your egg allergy. The doctor will evaluate your individual situation and provide personalized recommendations. After receiving the vaccine, you should remain at the vaccination site for 30 minutes for observation to ensure no allergic reaction occurs. If any adverse symptoms appear, such as rash, difficulty breathing, or dizziness, seek immediate medical attention.
