Russia is confident in the Sputnik V vaccine against all corona variants


On June 20, Alexander Gintsburg, director of the Gamaleya Institute – the leader in the development of the Sputnik V vaccine against COVID-19 in Russia, said that this vaccine is capable of fighting all known strains of corona virus, from disappearing. strain in the UK to the Delta variant discovered in India.

“Sputnik V protects us against all strains known today, from British to Delta Indian strains,” said Professor Gintsburg.

He noted that the Indian strain of COVID-19 causes a faster transition from mild symptoms to more serious illnesses.

Mr. Gintsburg said: “It [chủng Ấn Độ-ND] More aggressive, it reduces the time it takes to go from mild symptoms to more severe forms of the disease, thus cutting down on the time in which the body can develop antibodies.”

At the end of May, the results of research conducted and published by Russia and Argentina showed that the Russian-made and produced Sputnik V vaccine against COVID-19 was highly effective against the strain of the SARS-CoV-2 virus. discovered in the Brazilian city of Manaos and has now spread to a number of countries in the region and around the world.

Accordingly, after the 14th day of being vaccinated with the first Sputnik V vaccine, about 85.5% of the test volunteers had antibodies against the SARS-CoV-2 virus and by day 42 after receiving the second dose of the vaccine. Second, up to 99.65% of the volunteers had the above antibody.

Rogelio Pizzi, Dean of the Faculty of Medicine at the University of Cordoba, said that Sputnik V has a very good response in total anti-S antibodies (Immunoglobulin IgG anti-S), but it also has a special response in inactivation. antibodies, and that’s what it takes to suppress the virus.

The team has also reproduced and developed a variant of the virus discovered in Manaos that is 70% more contagious than the original – and the results of research conducted with Sputnik V show that this vaccine inhibits the growth of the virus. .

The Sputnik V vaccine is always proud of the Russian medical community and leaders because it is the first approved in the world and is more than 91% effective, and has a strong effect in reducing the progression of more severe disease if still infected. COVID-19.

On June 13, Russia tested a nasal spray COVID-19 vaccine suitable for children aged 8-12 and plans to launch this new product in September.

Gintsburg told a meeting with Russian President Vladimir Putin that the spray for children is used the same vaccine, only replacing the needle with a nozzle. The vaccine dose for children is expected to be ready for use by September 15.

The team tested the COVID-19 vaccine on children aged 8-12 and did not detect any side effects in the tested group, including no increase in body temperature.

However, Mr. Gintsburg did not give details about the study, such as the number of children participating in the study.

Last May, Russia licensed the Sputnik Light vaccine developed by Russia’s Gamaleya Institute.

According to RDIF, research data shows that the product is 79.4% effective in preventing COVID-19 while costing less than 10 USD/dose.

Sputnik Light is exported to countries where the outbreak is strong, thereby helping to increase the number of people vaccinated and help these countries fight the epidemic.

Previously, Russia had licensed the use of three vaccines against COVID-19 including Sputnik V, EpiVacCorona and CoviVac.

Although approved by 70 countries around the world, the Russian vaccine is not popular in the country.

Moscow is a hot spot among Russian cities for the number of COVID-19 infections. So far, there are 1,278,265 infections recorded in Moscow, including 9,120 cases in the past day, the highest level since the outbreak broke out.

TASS news agency said more updated information on June 20, in a week, Russia recorded 51,853 cases, the highest level ever. One of the reasons given by analysts is that the Delta variant recorded in India has a stronger spread that hit Russia in this wave. This mutation attacks so quickly that the human body, even after being vaccinated, cannot produce antibodies fast enough and large enough to fight the stronger attacks of the virus.

This also explains why many Russians have been re-infected with COVID-19 and some have been vaccinated but still tested positive.

Mayor Sergei Sobyanin told Rossiya-1 TV channel on June 20, about 1.5 million Moscow citizens were vaccinated with two doses of the COVID-19 vaccine and some of them were re-infected.

Among the new infections, there is almost no virus strain from China that causes the COVID-19 pandemic (known as the Wuhan strain), he noted.
