The Ministry of Health of Russia has registered the nasal vaccine against coronavirus Gam-Kovid-Vak (Sputnik V), which became the world’s first vaccine of this format, reported the press service of the department in Telegram.
“The vaccine, just like Sputnik V, consists of two components based on adenoviral vectors 26 and 5 types and is administered using a special spray nozzle into the nasal cavity at an interval of three weeks, that is, in the “prime-boost” mode, — said in the message.
The drug forms immunity on the mucous membrane of the respiratory tract. Patients have increased titers of IgA antibodies in the blood and nasal mucus and IgG antibodies that neutralize the virus in the blood. Also, the drug causes a cellular immune response to the coronavirus.
Now the drug is allowed to be used only for vaccination of patients over 18 years of age.
Murashko announced the registration of a nasal vaccine “in the coming days”
