Catterina Ferreccio, UC epidemiologist, on vaccination: "It is a mistake to rush the third dose"

We spoke with Catterina Ferreccio, epidemiologist of the Faculty of Medicine of the Catholic University regarding a possible third dose of vaccination.

In the Citizen DNA we talked with Catterina Ferreccio, epidemiologist of the Faculty of Medicine of the Catholic University, regarding the current situation of the pandemic in Chile and about a possible third dose of vaccination to face the coronavirus, Subject that she considers a mistake to rush.

"What we know at the Catholic University is that we studied the antibodies and discovered that when a second dose was given at 14 days and another at 28, was stronger at 28, Because if you have some antibodies circulating to a vaccine you're not going to respond as strongly.. It is a mistake to rush the third dose because what needs to be done is to protect young people and children.", The expert began by saying about what should happen with the vaccination of the national population..

To the above the epidemiologist added that the focus should be on vaccinating children "from 3 years and up", so that later they begin to think about a third dose of inoculation.

"Don't rush with seniors., because they have 60% protection with the vaccine. With personal protection, how to maintain distancing, wear a mask and keep washing your hands, You can get the other 50% needed, in order to be 100% protected. We must bring the vaccine and our behavior together.", assured the expert in conversation with the DNA Citizen.

Vaccine efficacy study: "It's not valid for the conclusions you draw"

On the other hand, the epidemiologist of the Catholic University commented on the results of a I am a student made by the Science and Life Foundation, which determined that "for the group over 70 years there was an important efficacy (on the part of the inoculation), but the rate of admission to intensive care units (Icu) of these cases is practically the same as before the vaccination process".

In the face of the above, The interviewee explained that "there are two studies on vaccine effectiveness".

"One that makes the group of Rafael Araos and Alejandro Jara del Minsal, which is the only one in which vaccinated and unauthorized people are compared to calculate the effectiveness of this, and the other is by Tomás Pérez-Acle, where they make an assumption that is that people over 70 are the same as those who are inside hospitals with those who are outside.. They have no information about whether or not the person is vaccinated.", Ferreccio assured.

Like this, The expert added that "the study that circulated is not valid for the conclusions it draws., because it doesn't have the necessary information".
