According to a Bloomberg report, Russia has claimed to register the world’s first COVID-19 vaccine by 12th of August,2020. The vaccine is reported to be developed by Moscow’s Gamaleya Institute of Epidemiology and Microbiology and the Russian Direct Investment Fund. The Bloomberg report further adds about the vaccine is to be in public use within 4 to 7 days of registration by drug regulatory. The efficiency of the vaccine is under question because the data about its trials has not been yet endorsed by Russia.
Has the Gamaleya Vaccine cleared all trials?
Generally, a vaccine needs to clear three trials before it gets in public; but this vaccine has cleared only first human trial and would be in use after the success of the second trial, while the third phase trial will be carried out even after its approval of use.
According to a report in TASS news agency, this candidate vaccine has successfully reported its phase-I trial in the last week of July, whereas the phase-II trial is to be started on July 13. Russia, however, is arranging to approve the vaccine without phase-III trial and is in quest of completing its phase-II trial as soon as possible.
Why three trials are required to approve a vaccine?
Before approving a vaccine for public use, it needs to clear three trials to ensure the safety of living beings. However, health experts and scientists warn and resist against the approval of any vaccine if it has not been gone through all three trials. According to them, releasing a vaccine in haste can cause inevitable side effects.
- In the first trial, a vaccine is tested to assess the safety of human beings. It is usually tested on a small of people and executes for a few weeks to months.
- The second trial goes on to test the ability of the vaccine to activate the immune system against disease. It is assessed on a few hundred volunteers in this phase.
- In the final trial, the vaccine is tested on several volunteers, usually thousands in numbers. People are sectioned in two groups, one group is injected with the vaccine, whereas, the other group is usually given a dummy vaccine. All volunteers are left to live their normal life. After a few weeks, they are assessed to measure the effects on the body or whether the vaccine has shown any resistance against the disease or infection. This phase of the trial can take several months to curb the disease.
Russia is trying to curb the Covid-19 with its constant test of a vaccine
The trial of one of the other Covid-19 vaccines is carried out at the Russian state virology institute. Several other COVID-19 vaccines are showing positive results. On July 27, the first 4 out of 5 have been injected.
” The Russian Defense Ministry tests the vaccine on volunteers in full compliance with the acting legislation and scientific methodological regulations, in order to prevent further risks, without any attempt to reduce the duration of the research.” A global news agency Sputnik has written about the Russian government’s statement.
