Question
Is there a risk of high blood calcium symptoms in children after receiving the D3 vaccine? How can one observe and judge this?
Answer
When children receive high doses of D3 vaccine (such as 900,000 units), there is a possibility of triggering high blood calcium symptoms. After vaccination, parents should pay attention to any changes in their child’s appetite, mental state, and sleep patterns. If they notice symptoms such as loss of appetite, irritability, constant crying, high fever, and vomiting, further examination of the child’s blood calcium levels may be necessary. Additionally, be aware of any white residues in the child’s urine, which could be a sign of excessive calcium intake. In such cases, reducing the child’s sun exposure time and avoiding high-calcium foods may help improve the symptoms.
