Question
An infant has experienced seizures and foaming at the mouth, along with confusion, after vaccination. This has never happened before during previous vaccinations. Parents are consulting about the possible causes and how to manage this situation.
Answer
Seizures and foaming at the mouth in infants after vaccination are usually not related to the vaccine itself but may be due to fever or low levels of calcium or magnesium in the body. Fever-induced seizures are more common, and when calcium levels are low, fever can exacerbate the occurrence of seizures. Treatment should first focus on fever reduction and anti-seizure therapy. If there is a deficiency in calcium, supplementation and anti-seizure treatment are also necessary. For infants under 2 years old, epilepsy is generally not considered as a primary concern.
