With the start of the third phase of the coronavirus vaccine from the Chinese-Canadian laboratory CanSino Biologics, so far 950 volunteers have been registered for a total of 1,000 doses to be applied in Oaxaca, reported Víctor Bohórquez López, director of the Network Osmo in Oaxaca.
For this reason, he asked the population of the state to continue registering as volunteers, in case any of those who have registered turn out not to be suitable for the vaccine to be applied after the clinical evaluation.
Oaxaca is the first state in the country to start phase 3 of this vaccine against COVID-19. Today, 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 and hypertension.
“There are inclusion criteria, but there are also exclusion criteria if you identify that you have an uncontrolled disease, such as diabetes and hypertension, they are exclusion factors,” explained Dr. Norma Rivera, who heads the research in Oaxaca for this vaccine.
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 that the volunteers will be monitored for a period of 12 months. Each week they will be called by phone to find out their health status and a physical check-up will be carried out 28 days after the application of the dose.
After six and 12 months of application, the volunteer will have to go to the facilities again to have blood samples taken and verify that the vaccine 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 lead a normal life, but that they must continue with prevention measures to avoid getting this disease; that is, they must continue to wear face masks, keep their distance, and frequent hand washing, among others.
