Some 300,000 doses of the
Russian Sputnik V vaccine
arrived in Argentina this Thursday.
All vials are "dose 1".
That is, the first of the two that each person must apply to acquire immunity to the coronavirus.
Therefore, in the last hours, there was great expectation for the
arrival of the second doses
.
“The vaccination begins today.
We have to wait at least 21 days for the second dose.
The second dose can be done
until days 60 or 75
, it is the indicated thing, ”said this Tuesday the Minister of Health, Ginés González García, at the Posadas Hospital, at the start of the vaccination operation.
In a cable released on Monday, government sources and the manufacturing process in Russia told Reuters that there were surpluses of the first dose and
delays in the manufacture of the second
.
Russia's first large international shipment of its 300,000-dose Sputnik V coronavirus vaccine to Argentina consisted only of the first dose, because it is
easier to prepare
than the second, according to the news agency.
The Gamaleya Institute, which developed the vaccine, says it is more than 91% effective after the two-dose course, but some Russian manufacturers are finding that the second dose, given 21 days after the first,
is less stable
, added two sources cited by Reuters.
Consulted by
Clarín
, from the Russian Direct Investment Fund (RDIF) they reported that the second doses will be delivered to our country
in January
.
“The 300,000 doses delivered to Argentina are the first component of the vaccine.
The second component of Sputnik V will
be delivered in January
in full compliance with the schedule, ”said Alexander Gintsburg, Director of the Gamaleya Center, which develops the vaccine.
Unlike other Covid-19 vaccines, which are administered as two injections of the same product, the Russian Sputnik V vaccine is based on two doses administered with
different inactivated viruses
, known as vectors.
"With the aim of ensuring long-lasting immunity, Russian scientists have developed the novel idea of using two different types of adenoviral vectors (rAd26 and rAd5) for the first and second doses of the vaccine, thus reinforcing its immunizing effect," says the site Sputnik V.
