Biolab Medical Laboratory conducts an unprecedented study to measure “T-cells” activation in COVID-19-vaccinated Jordanians


 The Research Department of Biolab Medical Laboratory – The Kingdom’s leading accredited diagnostic laboratory - announced that it is currently conducting an unprecedented study to assess the ability of the various vaccines used in Jordan (Pfizer, Sinopharm, AstraZeneca, and Sputnik) to activate T-cells specialized in fighting the Coronavirus disease. 

Head of the Scientific Research Department, Dr. Issa Abu-Dayyeh, stated that this study enabled Biolab Medical Laboratory to introduce a much-needed specialized test to measure the activity of T-cells against COVID-19 in previously infected and vaccinated people, for the first time in Jordan. 

With regards to the outcome of the study Dr. Abu-Dayyeh explained that the preliminary data suggest that the COVID-19 specific T-cells in the individuals who received two doses of the Pfizer or AstraZeneca vaccines were still activated -as seen by their ability to produce the cytokine Interferon-gamma (IFN-ɣ)- even after six to eight months following the second dose Conversely, this did not seem to be the case in those receiving a full vaccination regimen of the Sinopharm and Sputnik vaccines. 

Dr. Abu-Dayyeh added that the team is currently recruiting more participants to the study, and that work is underway to assess the effect of the booster shot on T-cell activation, this study he concluded “helps evaluate the currently available vaccines in a more comprehensive way by measuring their ability to stimulate T-cells in addition to the heavily explored B-cells” 

The founder and CEO of Biolab Medical Laboratory, Dr. Amid Abdel-nour, expressed his happiness that Biolab has once again succeeded to add a valuable immunological test to Jordan’s diagnostic armory in the fight against COVID-19. 

Dr. Abdel-nour added that the results of this study constitute solid scientific support to the big efforts made by the Jordanian Ministry of Health and the National Center for Security and Crisis Management, in making vaccines, including booster doses, available to all eligible citizens. 

As a regional pioneer in the field of medical diagnostics and laboratory testing, Biolab provides an extensive portfolio of more than 700 diagnostic services, catering to individuals, physicians, hospitals, and other laboratories across the Middle East. In Jordan, Biolab operates a total of 20 branches, in key locations throughout the Kingdom. 

Biolab’s is now the only stand-alone laboratory in the region that is endorsed by four international accreditation bodies, including the College of American Pathologists (CAP), Joint Commission International (JCI), ISO 15189 certification provided by the Jordanian Accreditation System (JAS) for quality health services, and the Health Care Accreditation Council (HCAC).
