Immunisation with Russia’s Sputnik V coronavirus vaccine and then revaccination with a nasal vaccine is likely to ensure full protection against COVID-19 infection.
However, this is yet to be studied in clinical trials, Alexander Gintsburg, director of the Gamaleya National Research Centre of Epidemiology and Microbiology, told Sputnik.
“We assume, although this will need to be studied during clinical trials.
“Such immunity will be sterile, that is, the vaccinated person will have not only humoral, but also mucosal immunity at the level of the entrance gate,” Gintsburg said.
