Peru has suspended trials for China's Sinopharm COVID-19 vaccine due to a "serious adverse event" that occurred with one of the volunteers for the study, The Sydney Morning Herald reports.
The health ministry said the event is "under investigation to determine if it is related to the vaccine or if there is another explanation".
Sinopharm Group Co Ltd, which is conducting its trials in Peru with some 12,000 volunteers, was about to complete the first stage of the trials in the next few days. Some 36,544 people have died so far in Peru from the coronavirus pandemic.
"The decision to temporarily suspend clinical trials is a safety measure contemplated in the regulations for clinical trials and protocols established to protect the health of research subjects, the health ministry said in the statement.
