If a child has a serious allergic reaction to a component of a vaccine, what should be done?

When a child experiences a serious allergic reaction to a component of a vaccine, it is crucial to prioritize their safety. In such cases, the child should not receive that specific vaccine due to the potential for a severe allergic response, which could lead to serious health complications. A serious allergic reaction, or anaphylaxis, can occur quickly and requires immediate medical intervention.

The decision to refrain from administering that vaccine helps to prevent any further risk to the child's health. In consultation with a healthcare provider, the child may also be evaluated for potential alternatives or modifications to their vaccination schedule. This approach ensures that the child is protected from both the disease that the vaccine prevents and from the risk of an adverse reaction.
