It is official information.
Says the Public Vaccination Monitor.
Until this Monday, in Argentina
25,178,202
people received a dose of the coronavirus vaccine.
And
only 7,157,189 received both
, 15.62% of the population.
In that gap of complete immunization - which raises the nerves of the health authorities in the face of
a third wave of infections
- Sputnik V is the one that is more in the red.
Among the immense group of inoculated with a dose throughout the country, there are those who this week will be four months waiting for the second Russian puncture.
Only in the City of Buenos Aires there are 180 thousand people who have already passed the three months, according to data from the Buenos Aires Ministry of Health.
The doubts are not lacking in the population that put the shoulder for the first time.
Nor are there too many answers about when component 2 of the Russian formula will arrive.
What is the real efficacy, not in the laboratory, 120 days after the first puncture?
Is there "concrete" protection with a single dose of Sputnik against the Delta variant?
Will AstraZeneca be received in replacement or will the wait continue?

"Next week
300 more liters
of Sputnik
component 2
will be arriving
," said the Minister of Health of the Nation, Carla Vizzotti this Saturday.
She was hopeful that with that arrival "we will have 1 and a half million second doses."
If their wish is fulfilled and that amount is produced on Argentine soil, at the end of August the group of people in the first paragraph
would spend almost 5 months waiting
.
But that is an "eventual" scenario.
Let's go back to the "completed" 4 months.
At the end of this note, the Ministry of Health of the Nation told
Clarín
that it had no information about upcoming flights of Aerolineas Argentinas scheduled this week to bring Adenovirus 5, part No. 2 of this vaccine from Russia.
Everything indicates that the 120-day gap is already written in the history of our vaccination plan.
"Sputnik has an efficacy of 80%, with one dose, and
falls between 10% and 15% compared to the Delta variant
, according to data still based on few cases. To these conclusions this week the data from the study of combination of vaccines ", explains to this newspaper Javier Farina, infectologist of the Argentine Society of Infectology (SADI).

In this sense, Vizzotti herself had also responded with other brands to the questions for Sputnik.
"Surely next week we will have data from local studies between Sputnik-Moderna and Sputnik-Sinopharm," he said on Saturday, pointing out that "all the information goes in the sense of safety" of "what it means to exchange vaccines."
The combination of the Sputnik V vaccines with Sinopharm and AstraZeneca
does not have serious adverse effects
, according to a preliminary study released on Friday by the Buenos Aires Ministry of Health.
The health portfolio detailed that 41.6% of the people who applied these combinations did not have any symptoms related to the vaccination, 8.4% referred low-grade fever and back pain and 50% pain in the area of application.
On Wednesday of last week, the Richmond laboratory reported that 500 liters of component 2 of the Sputnik V vaccine arrived in the country that "will allow to continue producing" more than
750 thousand doses
to continue completing the vaccination scheme against the coronavirus.

According to the laboratory, with this shipment, 760,000 doses of component 2 of the vaccine developed in Russia will be manufactured in Argentina, which "will soon be available" to society.
The Richmond Lab in Argentina is in charge, based on an agreement with the Gamaleya Institute and the Russian Direct Investment Fund (RDIF), to produce the Sputnik V vaccine in the country.
The strategy, then, despite the celebration for the arrival of the "liquid" from Moscow for its local completion, seems to point to the mixing of doses.
Do the antibodies from the first dose reach?
Eduardo López, head of the Medicine department at Gutiérrez Hospital and a member of the committee that advises the Government, warns
Clarín
about a
"preconception" or a "consolation of the poor"
among a portion of the group of people who are about to meet four months since the first russian injection.
"They believe that because they had covid before and received the first dose of Sputnik afterwards, they are covered. And they are not.
Nobody knows how long the antibody levels last with the first dose, four months later.
What is known is what that says the Gamaleya Institute, that the effectiveness against serious pictures is up to 79% after the first injection, at 45 days. And that it leaves memory in the cells to protect in case of reinfection. But from Russia they also recognize that
for the Delta variant the two doses are necessary
", mark.
Sputnik's complete protection exceeds 90% against the Delta variant.
"The logical thing would be that, in the event that there was
community circulation
of this variant, which is so contagious, it would be highly recommended that people be vaccinated with both doses. The same applies to the rest of the vaccines," he says.
Infections with the Delta variant of Covid could trigger a "third wave" of infections.

He talks about the fact that almost all the producing laboratories, such as Pfizer, Moderna, AstraZeneca and Sputnik V, issued statements and even published data saying that with a single dose the efficacy is "just over 50%".
In the case of Sinopharm, there is no data on its efficacy against Delta.
But that Chinese vaccine does not present a gap between the first and second doses in Argentina.
"
It is most likely that AstraZeneca is approved to combine it with Sputnik
, in the absence of component 2. But the vaccination should be completed before the arrival of the third wave, product of the new variant," closes the infectologist.
