The Secretary of Foreign Affairs, Marcelo Ebrard Casaubón reported that the first doses for phase 3 testing of the Chinese laboratory’s CanSino Biologics vaccine against Covid-19 have arrived in Mexico.  Ebrard stated that between 10,000 and 15,000 volunteers will participate in vaccine testing trials. The participants must be of legal age and will represent 37 percent of the total vaccine volunteers worldwide.


President Andrés Manuel López Obrador said that the tests on Mexican volunteers will be carried out in real time by the Federal Commission for the Protection against Sanitary Risks. The results will be reported 14, 28 and 120 days after the vaccine has been applied. The vaccine will be distributed in health centers in 12 states. Guanajuato will not participate as one of the states with volunteers.


Testing of the pharmaceutical company’s CanSino vaccine will be worldwide with between 30,000 to 40,000 volunteers from different countries including China, Argentina, Chile, Russia, Saudi Arabia, and Pakistan, among others. The  vaccines have already been tested among members of China’s national military.


“It is something very significant, that phase 3 begins in Mexico, and that we will soon have the results, because this will bring us calm, certainty,” declared President Obrador in his daily morning conference on Nov. 3.


The vaccines arrived in Mexico on Oct. 30, and were received by Foreign Relations officials. They have since remained under guard by the Secretary of the Navy, according to Martha Delgado, undersecretary for Multilateral Affairs and Human Rights.
