According to RIA Novosti, Gunzburg noted that in this regard, it is not yet possible to test the effectiveness of the Sputnik V vaccine against this variant of COVID-19.

“We do not yet have a strain of a new variant of the virus.

The efficacy of a vaccine can only be determined experimentally, and that just requires a strain, ”he said.

Earlier, Gunzburg spoke about the conditions for starting the development of a new version of "Sputnik V".
