💉On June 18, Russia allowed clinical trials of two forms of a potential COVID-19 vaccine developed by the Gamaleya National Research Center for Epidemiology and Microbiology.

💉The first vaccine, in the form of a solution for intramuscular administration, was carried out at the Burdenko Military Hospital.

↪️Another vaccine, in the form of a powder for the preparation of a solution for intramuscular administration, was carried out at Sechenov First Moscow State Medical University.

"The research has been completed, and it proved that the vaccine is safe. The volunteers will be discharged on July 15 and July 20," Smolyarchuk was quoted as saying in the report. There was, no further information on what phase of the clinical trials has this vaccine completed.

💉Earlier, the results of the COVID-19 vaccine tests showed that volunteers were developing immunity to the coronavirus.

↪️Did the vaccine conclude clinical trial or just phase 1?

The first stage of research on the vaccine at Sechenov University involved a group of 18 volunteers, and the second group comprised 20 volunteers.

After vaccination, all volunteers were expected to remain in isolation in a hospital for 28 days.

On average, it takes a minimum of 10-12 months to make a vaccine available for the general public after it is developed in a lab.

In some extreme cases, it may also take 10-12 years also—depending on how better we understand the pathogen.

Since the number of volunteers involved in the study was less than 40, the success only means that it has cleared phase 1 of a total of 3 phases of clinical trials

Even as per the WHO report, both the Russian vaccines from Gamaleya Research Institute are still under phase 1. As per the ClinicalTrials.gov database, phase 1 for these vaccines was estimated to be complete by August 15.

The overall number of global COVID-19 cases was nearing 1.3 crores as of Monday morning, while the deaths have increased to more than 5.68 lakh according to the data compiled by the Johns Hopkins University.
