Undersecretary of Public Health, Christopher Square, commented that the National Pandemic Response Commission (CNRP) is analyzing the possibility of an eventual fifth dose against covid-19. In addition, he did not rule out the option that people could be inoculated once or twice a year.
“Currently, we’re looking at protection data over the next few months in people who have had their fourth dose, so we know how long that protection lasts. That’s a question that’s not fully settled yet, so the decision definition of when and to whom it will be necessary to inoculate with a fifth dose is still under evaluation,” he said.

Although he assured that “most likely, according to scientific consensus, is that this is a virus for which we are going to need to vaccinate recurrently over time as we do against influenza. Most likely, we are going to have a change of logic to have a daily vaccination that will require one or two doses a year, depending on the viral circulation of the variant in question and also the risk of the group. The discussion among CNRP experts is advancing along these lines.”
Also, the authority confirmed that during this year, the inoculation will continue according to the time that has passed since the last dose. Finally, he stressed that “eventually by 2023 we will be in a mode more similar to influenza, vaccinating at certain times of the year.”
