What is Sputnik Light, the Russian single-dose vaccine | Digital Trends Spanish


Russia announced the start of a clinical trial of Sputnik Light, a version of its one-dose COVID-19 vaccine.

Russian authorities believe that it could become a possible “temporary” solution to help countries with high infection rates.

“Open trials of safety, tolerance and immunogenicity of the drug Sputnik Light in the prevention of infection caused by the SARS-CoV-2 virus,” says the document approved by the Russian Ministry of Health.

The vaccine Light it will be tested on 150 people in Moscow and St. Petersburg before receiving authorization.

On August 11, 2020, Russia approved Sputnik V, its first vaccine against COVID-19 developed by the Gamaleya Institute and applied in two doses.

The original antidote will remain the main version used for the inhabitants of Russia, but the single-dose alternative could be destined for export.

“[La] Sputnik Light can serve as an effective temporary solution for many countries, which are experiencing a peak in coronavirus infection, “said Kirill Dmitriev, director of the Russian Direct Investment Fund (RDIF).

According to the Russian agency Sputnik, the original antidote uses two different vectors based on the human adenovirus.

In this way, it can offer a stronger and longer immune response than vaccines based on the same vector for two doses, according to the developers.

However, the version Light It consists of only the first component and can be administered only once.

The developers estimate that the vaccine could achieve an efficacy of up to 85 percent and a shorter protection period, unlike Sputnik V, whose effectiveness has been placed at 91.4 percent, according to Russian authorities.
