A medical staff in the U.S. who received the Corona 19 vaccine developed by pharmaceutical company Pfizer had an adverse reaction and then died, and health authorities began investigating the cause.



Local media reported that a man who worked as an x-ray technician at a hospital in Santa Ana, California, USA, died four days after receiving the Pfizer vaccine.



Reportedly, the man who died was 60 years old and finished the second vaccination on the 5th, but after a few hours, he suffered adverse reactions such as shortness of breath and upset stomach.



The man later had a drop in blood pressure, abnormal kidney function, and died on the 9th after receiving treatment with a respiratory tract attached.



"My husband was a bit overweight with high blood pressure, but there was no health problem," said the wife of the man who died.



In response, local police said they are investigating the cause of Juke's death, and will notify health authorities if it determines that there is a connection to the vaccine.



In Miami, Florida, USA, an obstetrician and gynecologist died of a brain hemorrhage 16 days after vaccinating Pfizer, and authorities are investigating it.



Also, on the 21st, a resident of Placer County, California, died hours after vaccination, and health officials are investigating the cause of death.
