The measure is to be announced this week and the vaccine will be administered to vulnerable groups by mid-September, the newspaper informed, recalling that there were doubts a month ago about the need to administer a third anti-Covid dose in the country.

In view of the high transmission rate of the Delta variant, in which the number of Covid-19 patients in unvaccinated people and those with a complete vaccination scheme increased in July, Apoorva Mandavilli, a science reporter for this newspaper, warned about the contagions in the latter population group.

Mandavilli pointed out that data provided by California, Colorado, Massachusetts, Oregon, Utah, Vermont and Virginia confirmed higher percentages of immunized patients than previously expected among those coronavirus cases, hospitalizations, and deaths, although this trend is not generalized.

Despite the contagions, the so-called progressive infections in fully immunized persons are not common, and most seriously ill patients who die are not immunized, according to officials.

‘The main conclusion is that vaccines are really excellent, but they are not a perfect shield against the Delta variant. Vaccinated people should be careful, especially if they are at high risk,’ she concluded.
