Government guarantees 200,000 second doses of Sputnik V in July

Vice Minister for Foreign Trade Benjamin Blanco assured that 25,000 second doses of the Sputnik-V vaccine will be received by July 9, and another 200,000 vaccines will arrive by July 19. According to the authority, the Russian fund assured that there will be no shortage.

It also guaranteed the second of the AstraZeneca vaccines.

However, amid reports of a possible shortage of second doses of Sputnik V and AstraZeneca, epidemiologists are suggesting two solutions: One that they consider “workable” is to combine vaccines to continue the program and immunize a larger percentage of the population achieve herd immunity; the other is to wait for cans of the same brand to arrive.

“It is expected to receive 25,000 second doses in the first week of July and 200,000 second doses between July 15th and 19th.” The declaration comes from the Vice Minister for Foreign Trade and Integration. According to the authority, the doses will arrive in the country in time to complete the vaccination schedule.

The first 25,000 doses of the Russian vaccine arrived on April 10th. “That’s why there is nobody who has completed 90 days,” says Blanco. The arrival of a first batch of second doses in the first few days of July will complement the vaccination process.

The deputy minister referred to the statement of the Russian Fund, which “assured us that you will have no difficulty in administering the second dose on time”.

Possible defect

In an emergency, the government has opened up the possibility of using a different brand for the application of the second dose, said Deputy Health Minister Álvaro Terrazas.

“In some European countries they are already giving one of the other vaccines as a second dose and warning that this will make the immune response even more effective, but these are studies that have not been done on our continent.” suggested the epidemiologist Virgilio Prieto.

However, he thinks it is “feasible” to opt for a brand other than the first to meet the second dose, given the genetic sequence used to make the vaccines.

One of the first combination studies is that of the University of Oxford, mentioned the epidemiologist Guillermo Accounts. “From a technical point of view, it is doable and this is not the first time this has been addressed,” he said.

There are also several ongoing studies examining the effects of combination vaccines, another option is to restart the vaccination schedule with a different dose. However, the World Health Organization (WHO) has not approved vaccination with an immunizer from another laboratory, said Alejandra Hidalgo, deputy minister for health insurance and health systems administration.

Epidemiologist Christian Gómez said it would be useful to maintain the recommendation made by pharmaceutical companies to keep first and second doses with vaccines of the same brand if there is no scientific evidence of the combination’s effectiveness.

The goal is immunity

Epidemiologist Virgilio Prieto said it was important to stick to the vaccination schedule because “the body needs a supplement to have a lot of serological antibodies that can respond to a real infection”. a population susceptible to vaccination has already been vaccinated. “As a result, one virus stops circulating because the rest (unvaccinated) is a population that is unable to produce large reproductions of the virus,” adds epidemiologist Guillermo Accounts.

“Once you’ve contracted the virus, the symptoms are very mild and protect you from complications and the risk of losing your life,” he said.
