LIMA-The Peruvian health minister said that China’s Sinopharm could resume a trial for its coronavirus vaccine in the hard-hit Andean nation, just days after authorities suspended the tests to better understand why a volunteer had fallen ill.

Health authorities announced over last weekend that the Sinopharm trial would be temporarily halted as a safety measure after a volunteer experienced decreased strength in his legs, among other symptoms.

“We have had several meetings with Sinopharm and… the suspension has been lifted today (Wednesday),” Health Minister Pilar Mazzetti said.

Sinopharm Group Co Ltd, which is conducting its trials in Peru with nearly 12,000 volunteers, was about to complete the first stage of the trials in the next few days, and had plans to administer a second dose of its vaccine in the coming weeks.

Peru’s government said on Tuesday negotiations with Sinopharm to purchase COVID-19 vaccines are “well advanced.”

Peru had reported 989,457 cases of coronavirus as of early Friday, and 36,848 deaths.
