Results of Russia's COVID-19 vaccine produced antibody response

(Moscow) 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 and involving 76 participants, showed 100% of participants developing antibodies to the new coronavirus and no serious side effects, The Lancet said.
Russia licensed the two-shot jab for domestic use in August, the first country to do so and before any data had been published or a large-scale trial begun.
"The two 42-day trials – including 38 healthy adults each – did not find any serious adverse effects among participants, and confirmed that the vaccine candidates elicit an antibody response," The Lancet said.
"Large, long-term trials including a placebo comparison, and further monitoring are needed to establish the long-term safety and effectiveness of the vaccine for preventing COVID-19 infection," it said.
The vaccine is named Sputnik-V in homage to the world's first satellite, launched by the Soviet Union.
