“The nasal form of the Sputnik vaccine has already been registered based on the results of the first and second phases of trials.
In a week or two, we plan to start the third phase, which will experimentally show that after a nasal vaccine a person has sterile immunity, ”TASS quotes Gunzburg.
According to him, such a study and its results can be a fundamentally new step in the fight against airborne infections.
Earlier, Gunzburg said that a test system for determining immunity in those vaccinated with a nasal preparation against coronavirus already exists.
On April 1, the Russian Ministry of Health registered the world's first nasal vaccine against COVID-19 coronavirus infection.
