Gunzburg justified the joint use of the nasal vaccine with Sputnik V

It will be possible to refuse intramuscular vaccination against the Sputnik V coronavirus only if the nasal vaccine is 100% effective. Such a statement on February 19 was made by the director of the Research Center for Epidemiology and Microbiology. Gamalei Alexander Gintsburg

During the conversation, the correspondentRIA Newsasked the expert why the Sputnik V injection, which protects against a severe course, if the nasal vaccine protects against infection.

“When we find out, as a result of large statistics, that the nasal vaccine protects by 100%, then the Sputnik V injection will not be needed, and if we understand that it protects by 70-80%, then we will need to do and more,” Gunzburg answered.

Earlier, on February 18, the scientist said that the Research Center for Epidemiology and Microbiology. Gamalei developed a test system for determining immunity after a nasal vaccine against COVID-19.

As Gunzburg emphasized, now it has become possible to determine immunity not only by a blood test, but also by a swab from the nose.

On February 16, immunologist Nikolai Kryuchkov, Candidate of Medical Sciences, told Izvestia that nasal vaccines against COVID-19 can contribute to the formation of immunity in the upper respiratory tract.

However, according to Kryuchkov, it is not yet clear whether the nasal vaccine will be effective enough, but he suggested that it would be less effective than intramuscular.

On February 15, clinical trials of the Generium coronavirus nasal vaccine began in Moscow. 660 people will take part in them. Volunteers will be divided into two groups. Each participant will receive an intramuscular injection and a nasal injection on Days 1 and 21. One group will have the study vaccine as a spray and a placebo as an injection, while the other group will have the opposite.

In December 2021, the Russian Ministry of Health issued Generium permission to conduct phases 2 and 3 clinical trials of the GNR-099 combined vector vaccine against coronavirus.

In the Russian Federation, a large-scale vaccination campaign is underway. Citizens are vaccinated for free. Six vaccines against coronavirus have been registered in the country: Sputnik V, which became the first vaccine against COVID-19 in the Russian Federation and the world, as well as Sputnik Light, Sputnik M, EpiVacCorona, EpiVacCorona-N and KoviVac .
