    MOSCOW (Sputnik) - Sputnik Light COVID-19 vaccine can be used for revaccination, which will increase the level of antibodies against all circulating strains, Alexander Gintsburg, the chief of the Russian Gamaleya Research Centre, told Sputnik.

    "Revaccination with 'Sputnik V' can be done. There are absolutely no problems. Currently, the so-called single-component version of the vaccine, 'Sputnik Light,' is registered. It is registered, among other things, in order to raise the level of antibodies after illness or some time after vaccination", Gintsburg said.

    The Gamaleya chief added that the revaccination with Sputnik Light would develop antibodies against all existing COVID-19 variants.

    The slimmed-down version of the vaccine was registered in late March as an alternative to the main two-shot Sputnik V after successfully undergoing all three phases of clinical trials. The latter remains the main option for export and internal use in the country.
