OREANDA-NEWS. Sputnik's nasal form will effectively protect against the omicron strain, according to the developer's Twitter account.

"Not only from the point of view of protecting against the virus itself, but also from the point of view of preventing its transmission," the publication says. The drug will enter the market in the first quarter of 2022.

In mid-October, it became known that the Ministry of Health authorized clinical trials of the SPRAY 08-Gam-COVID-Vac-2021 vaccine, developed by the Gamaleya Center. As pointed out by Gunzburg, there were no side effects of the nasal preparation. According to his deputy Denis Logunov, such a procedure is painless and is aimed at creating an additional barrier in the form of immunity in the upper respiratory tract.

This week, Vladimir Putin said that he had been vaccinated with a nasal vaccine against coronavirus and that he had no discomfort after that.

Vaccination remains the most reliable way to protect against COVID-19. According to the head of the Russian Ministry of Health Mikhail Murashko, the proportion of those vaccinated among COVID-19 patients does not exceed four percent, while the vast majority of patients in hospitals are unvaccinated. At the end of September, the WHO announced the connection of mortality from SARS-CoV-2 with the refusal of preventive immunization.
