“We are showing, based on the data, that we have a very ceffective vaccine,” said RDIF head Kirill Dmitriev, adding that it was the sort of news that the vaccine’s developers would talk about one day with their grandchildren.
The interim results are based on data from the first 16,000 trial participants to receive both shots of the two-dose vaccine, the Russian Direct Investment Fund (RDIF), which has been backing the vaccine and marketing it globally, said.
The interim analysis was conducted after 20 participants in the trial developed COVID-19 and examined how many had received the vaccine versus a placebo.
That is significantly lower than the 94 infections in the trial of a vaccine being developed by Pfizer Inc and BioNTech. To confirm the efficacy rate, Pfizer said it would continue its trial until there were 164 COVID-19 cases.
The Russian trial will continue for six more months, RDIF said in a statement, and data from the trial will also be published in a leading international medical journal following a peer review.
