Russia's Covid-19 vaccine showed antibody response in initial trials

COVID-19 | Russia’s "Sputnik-V" Covid-19 vaccine produced an antibody response in all participants in early-stage trials, according to results published on Friday by The Lancet medical journal that were hailed by Moscow as an answer to its critics.

The results of the two trials, conducted in June-July this year involving 76 participants, showed 100 percent of participants developing antibodies to the new coronavirus and no serious side effects, The Lancet said.
