Injected into Our Body
The most severe reactions often occur when allergens are injected into the body and gain direct access to the bloodstream. This intravenous access carries the increased risk of a systemic reaction, such as anaphylaxis. The following are commonly injected allergens that can cause severe allergic reactions:
- Insect venom
- Vaccines (including allergy shots)
- Hormones (for example, insulin)
