The delta version is wreaking havoc in countries that have made massive strides in vaccination planning. The United Kingdom, which will lift all restrictions tomorrow, is going through a rebound that has placed it as the country with the most positive cases in the past 24 hours.
There were more than 54 thousand infections as against 51 thousand in Indonesia, 41 thousand in India and 34 thousand from Brazil. It comes in the midst of a vaccination campaign that has covered 66 percent of the population on two doses and over 80 on one dose, including in Scotland, Wales and Northern Ireland.
According to a King’s College study, 47 percent of infections in Great Britain are from vaccinated people, but it does not specify that with one or two doses. This situation led to the criticism of Boris Johnson’s strategy by over 1,200 scientists. paper addressed to the magazine the Lancet In which they accuse him of conducting an “experiment” with the population and returning to the controversial theory of “group immunity”.
Concern for these hours focused on questions about the effectiveness of vaccines and a third booster dose or return to the vaccination schedule.

LPO spoke with Adrian Alasino, Director of the School of Medicine of the National University of Mar del Plata, who said that “the international panorama brings us many surprises and adds uncertainty to the situation in Argentina in the short term because there are things that we do not know.” For example, the number of cases with vaccinated people or the impact of this new variant is a scenario that is not entirely clear.”
The academic clarified that “there is still a third wave in Argentina and the region and we don’t know what the impact will be. It is important that we go ahead with the first dose but the second one needs to be accelerated because we are too short.” ” “The impact of the third wave will depend on the level of vaccination,” he said.
Alasino warned that “the outlook is uncertain, with the most important strategy being vaccination and, in Delta’s case, closing the borders that allow us to gain ground.” It is very difficult to predict but we think there will be a pandemic for some time. This will greatly complicate the sector due to the problems of social inequality and the deterioration of the health system.”
Regarding the delta version, the expert explained that “with both the possibility of a third dose and a return to the vaccination program, the scenario is uncertain and unknown.”
On the other hand, the LPO also consulted the head of Sanitary Zone VIII Gaston Vargas, who said that “the variable delta has been shown to be much more contagious, but there is no evidence that it is more lethal than the others. What happens when It’s more cases, more demand for the system and more risk of saturation.”
Vargas assured that “vaccines implemented in the country are effective and give good results with one or two doses. It is not possible to stop the arrival of the new version but we can delay it and expand the support base of vaccines.” “This is another face of the pandemic that will not be foreign to the region and the country,” he warned.
Regarding the possibility of a review of vaccines due to the infectivity of the new variant, the official stressed that “vaccines can be reviewed but it is important to note that this continues to prevent serious infections and lower mortality rates.” Despite the new forms it continues to achieve. What it did not manage to contain the number of infections is the reason why health systems are saturated”. “When you don’t gain herd immunity, the virus mutates and gives rise to these variants. So the original broad-spectrum vaccine may not be as effective, but that hasn’t happened in the world yet,” he said.

Gaston Vargas said that “it is not possible to get out of the context of the pandemic and it is very likely that this will prompt us to review the vaccines.” “As the virus continues to spread, unless there are cuts, we risk having to review vaccines, add doses or exceed them as the coronavirus comes running the arc all the time,” he explained.
In the end, Gaston Vargas noted that “the United Kingdom decreased the mortality rate, without a vaccine they would have had the same number of cases and many more deaths.” “With this data we can say that the vaccines work well. If 500 died and now 50, despite the increase in cases, that is a positive indicator,” he concluded.
The drop in cases and the lifting of restrictions in the United Kingdom and Israel generated excitement about a possible exit route from the pandemic, but the rise in infections from the delta variant raised a huge question mark that worries a region facing a third wave.
