The 9th grader, whose identity was not released by authorities, died Tuesday. She received her first Pfizer shot on Dec. 3, 2021, and experienced adverse reactions, including dizziness and difficulty breathing.

She received her second dose of the Pfizer vaccine Monday, and again developed adverse reactions such as tightness in her chest, dizziness, breathing difficulties and seizures, according to VN Express.

The girl received emergency treatment from medical officers at the vaccination site before being transferred to the Ha Hoa District medical center. Her condition rapidly deteriorated upon arrival at the hospital where she began to vomit blood. She later fell into a coma and died.
