With the start of the third phase of the Chinese-Canadian vaccine from the CanSino Biologics laboratory, so far 950 volunteers have been registered for a total of 1,000 doses to be applied in the state, reported Víctor Bohórquez López, director of the Osmo Network in Oaxaca.
For this reason, he asked the state population to continue registering as volunteers, in case some of those who have registered turn out to be unfit to be given the vaccine after the clinical evaluation.

Oaxaca is the first state in the country to start phase 3 of this vaccine against COVID-19. On Friday it was applied to the first five volunteers who registered after signing a document with their informed consent and passing clinical tests, in which it is determined if they do not have any uncontrolled disease such as diabetes or hypertension.
“There are inclusion criteria, but there are also exclusion criteria if it is identified that you have an uncontrolled disease, such as diabetes and hypertension, they are exclusion factors,” explained Dr. Norma Rivera, who is leading the research in Oaxaca.

The specialist recalled that there were already two study phases carried out by the CanSino Biologics laboratory, in which the vaccine did not generate adverse effects in the patients who underwent these analyzes.
In Oaxaca, he explained, the volunteers will be monitored for a period of 12 months. Every week they will be called by phone to find out their health status and a physical check-up will be done 28 days after applying the dose.
Subsequently, six and 12 months after the application, the patient will have to go to the facilities again to have blood samples taken and verify that the vaccine has generated antibodies or defenses against COVID-19.

Víctor Bohórquez added that the decision to transport patients from their homes to the laboratory and from the laboratory to their homes once the vaccine has been applied is to protect the integrity of the volunteers.
He also reiterated that receiving the dose does not mean that they will lead their normal life, but that they must continue with preventive measures to avoid contagion.
