Russia’s debatable COVID-19 vaccine showed symptoms of generating an immune reaction in an early test, according to a report published in The Lancet on September 4.
The report includes the main points of two first phase 1/2 studies of the vaccine, Sputnik V, in two hospitals in Russia.
Researchers enrolled 76 participants in any of the studies, 38 in the study, between June and August.Participants were between 18 and 60 years old and were followed for 42 days after initial management of the candidate vaccine.
During this heavily monitored period, researchers reported that all participants who won the vaccine developed antibodies opposed to the SARS-CoV-2 virus, which causes COVID-19, within 3 weeks.
Although some side effects have been reported, the maximum non-unusual is pain at the injection site and fever, the vaccine has been shown to be and is well tolerated.
Sputnik V is composed of two strains of adenovirus, which cause the unusual cold, to bring the SARS-CoV-2 peak protein gene.
This approach is used by AstraZeneca and the University of Oxford, whose vaccine candidate uses a modified chimpanzee adenovirus.
A large-scale phase 3 trial is planned to recruit 40,000 volunteers of other ages and risk groups, with the first effects of this expected in October or November.
Despite the lack of falsified evidence from a confirmation study, Russia granted regulatory approval for Sputnik V in August.
There has been widespread reaction around the world, and fitness experts warn that approval has not prevented the final touch of Phase 3 testing.
Following Lancet’s report, scientists said that while the initial effects are promising, it is vital that there is very little knowledge to definitively verify efficacy.
“Immunogenicity bodes well, no immunogenicity can be inferred in older groups, and the clinical efficacy of a COVID-19 vaccine has not yet been demonstrated,” said Naor Bar-Zeev, assistant professor at Johns Hopkins Bloomberg School of Public Health..
“Since vaccines are given to other healthy people and the COVID-19 pandemic, potentially all after approval after phase 3 trials, protection is paramount,” he added.
Russian President Vladimir Putin said last month that one of his daughters had volunteered for the vaccine, adding that she “feels and has a large number of antibodies” after receiving the vaccine.
Sputnik V evolved through the Gamaleya Institute in Moscow, which it criticized after researchers and administrators injected the prototype months ago, going through the same old human trial launch procedure.
