The nasal vaccine against coronavirus, which the Gamaleya Research Center for Epidemiology and Microbiology is working on, will be two-component, but if it is used as a booster, then one vaccination is enough.
Director of the center Alexander Gintsburg told RIA Novosti.
Earlier, the deputy head of the Gamalea Center Denis Logunov said that the nasal version of the “Sputnik V” vaccine against COVID-19 creates an additional barrier in the upper respiratory tract in the form of immunity and has minimal side effects.
