Injecting food proteins causes the development of food allergies. Vaccines contain numerous food proteins such as peanut, sesame, cow's milk, wheat, corn, gelatin, egg, fish etc. The only option to completely avoid the risk is to avoid vaccines. Avoiding vaccines obviously makes you vulnerable to vaccine preventable diseases (VPD). With current vaccines, you can therefore only attempt to reduce risk of food allergies but cannot completely avoid the risk. Similar description applies to autism, asthma and autoimmune disorders such as type 1 diabetes. Details of strategies to reduce risk are described.
