doctor in her 50s who received Pfizer's corona vaccine died of cerebral hemorrhage 16 days after vaccination, the New York Times reported.



The doctor's wife, who died, said that three days after her husband got the vaccine, he had spot-shaped bleeding in his hands and feet, so he went to the emergency room.



The doctor was known to have no underlying medical conditions.



While the US Centers for Disease Control and Prevention (CDC) is undertaking an investigation, vaccine maker Pfizer says no link has been found between vaccines and deaths.



In Ohio, the United States, a mutant coronavirus was discovered, causing an emergency.



Both new coronaviruses discovered in Ohio are of two species, and unlike the mutant viruses in Britain and South Africa earlier, U.S. quarantine officials said.



One of the two newly discovered mutant viruses has been found to have spread widely throughout Columbus, Ohio's capital, three weeks ago.



Ohio State University said it is true that the new mutant virus is highly contagious, but that the vaccine currently being vaccinated appears to be preventable.
