Russia registers the world’s first coronavirus vax nasal spray
MOSCOW – The world’s first nasal coronavirus vaccine has been registered in Russia, the health ministry said in a statement on Friday.
“The Russian Ministry of Health has registered the nasal spray form of the coronavirus vaccine Gam-COVID-Vac (Sputnik V) developed by the Gamaleya Research Institute of Epidemiology and Microbiology of the Ministry of Health,” says the press release.
According to the ministry, the vaccine consists of two components based on type 16 and type 5 adenoviral vectors. The two doses will be given three weeks apart.
This type of vaccination creates mucosal immunity against the coronavirus in the respiratory tract.
“The use of a nasal spray induces a humoral immune response (boosting IgA antibody titers in the blood and nasal secretions and virus neutralizing IgG antibody titers in the blood) and a cellular immune response to the infection caused by SARS-CoV-2,” the statement added.
At this stage, the vaccine is intended for the immunization of persons over 18 years of age.
Russian Health Minister Mikhail Murashko said earlier that the use of the nasal spray coronavirus vaccine would be included in recommendations for booster shots. (CASS)
