JEDDAH: King Abdullah International Medical Research Center (KAIMRC) in Saudi Arabia is preparing to take part in advanced trials of one or two COVID-19 vaccines. About 40 potential vaccines are being tested on humans, nine of which are at the advanced stage of clinical trials to evaluate their safety and effectiveness in protecting people against a virus that has infected more than 31 million people around the world. The center confirmed its readiness to cooperate with the Kingdom’s Ministry of Health and the Saudi Food and Drug Authority (SFDA) and participate in tests of one or two of the nine vaccines that are in the third phase of clinical trials, during which large-scale testing on humans takes place. Dr. Naif Al-Harbi, the head of KAIMRC’s drug-development unit, told Al-Ekhbariya TV news channel that it is unprecedented to have nine vaccines in stage three of clinical trials so soon, less than a year, after the emergence of a new virus. “Approval or disapproval of any drug normally follows the third stage of its clinical trials, which is the last stage,” he added. “Since the pandemic, KAIMRC has been in continuous contact with a number of drug companies in four countries (that are developing vaccines).” KAIMRC has been working with one Chinese pharmaceutical company in particular to help evaluate and accelerate the development of its vaccine, he said. “Over the past two months, we have been in contact with Sinovac to scientifically evaluate its product, in term of the tests on animals and a study of the results of stages one and two on humans,” Al-Harbi said. He added that the Kingdom’s Ministry of Health is working with a different Chinese company to evaluate whether the vaccine it is developing is effective. A number of factors are taken into consideration when reaching a conclusion. “We examine the drugs and make sure they have caused no side effects when tested on humans, or that they just caused insignificant side effects,” said Al-Harbi. “We also look into the manufacturing company’s profile to ensure it follows the standards of the good manufacturing practices, and that the company’s products are consistently produced and controlled according to quality standards.” He added that SFDA is also doing a great job in ensuring that vaccines are safe, to avoid any risks to the health of people in the Kingdom. In a message posted on Twitter, KAIMRC said that some countries, such as Russia, China and the UAE, have given doctors the green light to use some vaccines on patients before that have been approved, but only in emergency cases and when the results of early clinical studies indicate that the vaccine is safe. On Monday, Saudi Arabia announced 27 additional COVID-19-related deaths. The death toll in the country now stands at 4,512.
