translated from Spanish: Sinovac and Pfizer-BioNTech vaccines show 90% and 98% effectiveness in Chile

The second region that shows the most decline is Magallanes, which has decreased its cases 37.4% in the last 14 days and 30.1% in the last week. On the other hand, “the positivity rate of the PCR test has been slowly but steadily decreasing, and at this time the positivity rate at the national level is 6.9%,” the authority said. In addition, the minister released vaccination figures against COVID-19. He said that as of yesterday afternoon, 12,467,055 people had been vaccinated with one dose. This is equivalent to 82.02% of the target population. And with two doses “we have vaccinated 10,289,270 people, which is equivalent to 67.69% of the target population, who have already completed their vaccination schedule,” he said. Then, Dr. Rafael Araos, advisor to the Undersecretariat of Public Health, referred, who delivered the third update of the Analysis of Effectiveness of coronavac vaccines in Chile and new information on the immunization process.” It is important to mention that as we progressed in the coverage of the vaccination program, with people who have already completed their immunization schedule, we were seeing a remarkable change in people who became ill with COVID-19. And currently a large part of the people who make the infection correspond to young people who are not immunized, that is, who have not received the vaccine, who have received only one dose or who are not yet within the protection period,” Araos explained. He added that “that should be absolutely clear, because saying that the vaccine didn’t work has a negative effect on the progress of the program, on people’s confidence and that’s the worst thing that can happen to us right now.” The doctor noted that those positive results are reflected in the figures they handle, which indicate that only about 25% to 30% of people who get sick have received their full vaccination schedule. In addition, the majority of people who are hospitalized for this disease are unc vaccinated people, as well as those admitted to intensive care units, who only 26.36% have a competing vaccination schedule.” With this we can say with certainty, based on our vigilance, that there is an association that allows us to say that the displacement of cases to unauthorized persons and young people has to do with the vaccination program. This is reflected in the effectiveness analyses”, explained Rafael Araos.Regarding the effectiveness of the Coronavac vaccine (Sinovac), the Effectiveness Analysis reflects that after 14 days since the second vaccine is administered, it achieves between 63% and 64% immunity, that is, if it was projected that 100 people would get sick with symptoms without the vaccine , with the complete vaccination schedule only 36.As for hospitalization, the effectiveness is between 86.8% and 87.8% and admission to intensive care units is 90%, which means that if 100 people are expected to require intensive treatment for getting sick with COVID-19, with both vaccines administered and after 14 days , this figure drops to 10 people. Finally, the vaccine has an 86.4% effectiveness to prevent deaths from the SARS-CoV-2 virus.On the other hand, on this occasion, the authorities released the effectiveness figures that the Pfizer-BioNTech vaccine has shown in our country and with which almost five million doses have been administered. This vaccine is effective in preventing 90.9% of infections, 97.1% of hospitalizations and 98.4% of admissions to intensive care units. In addition, it decreases the chances of death by 91.8% to people who completed their vaccination schedule.
