The nasal vaccine against coronavirus infection will need to be vaccinated every six months, said Alexander Gintsburg, director of the Gamaleya Research Center for Epidemiology and Microbiology.
“Once every six months [you will need to be revaccinated with a nasal vaccine],” Gunzburg answered the corresponding question from RIA Novosti.
On March 18, the Gamaleya Center applied to the Ministry of Health of the Russian Federation with a request to register a nasal vaccine against COVID-19.
On February 19, Gunzburg said that it would be possible to refuse intramuscular vaccination against the Sputnik V coronavirus only if the nasal vaccine is 100% effective.
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.
Prior to that, in December 2021, the Russian Ministry of Health issued Generium permission to conduct the second and third phases of clinical trials of the combined vector vaccine against the GNR-099 coronavirus.
