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.

“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.

 

Dmitriev said at least 3,000 people had already been recruited for the large-scale trial of the Sputnik-V vaccine launched last week, and initial results were expected in October or November this year.

Commenting on the results of the early-stage trials, lead author Dr Naor Bar-Zeev of the International Vaccine Access Center, Johns Hopkins Bloomberg School of Public Health, USA said the studies were “encouraging but small”.
