Teacher Who Got Mixed Vaccine Doses Died of Brain Stem Swelling, Thai Officials Say

Coronavirus Covid-19 Vaccination Vaccine Jab Shots Thailand Bangkok-2

A Prachuap Khiri Khan who died after mixing doses of two coronavirus vaccines suffered cerebral swelling that pressed on her brain stem, the Department of Disease Control said.

The 39-year-old had been given AstraZeneca Plc.’s vaccine as a second dose after an initial jab of CoronaVac, made by China’s Sinovac Biotech. There is scant evidence on mixing-and-matching vaccines and the World Health Organization recently warned individuals against doing so.

Dr. Chawetsan Namwat said doctors monitoring side effects from vaccinations would consider the autopsy result with other pieces of evidence before concluding if the death was related to the Covid-19 vaccinations.
