Russia has just approved a vaccine opposed to coronavirus to be used in tens of thousands of people, its effectiveness has not been very well tested, according to reports.
Russia named the newly approved vaccine “Sputnik V”, referring to the world’s first synthetic satellite, which introduced the area race, Reuters reported. Russian state television presented the global effort to expand a coronavirus vaccine as a similar “race,” and in pronouncing Sputnik V’s approval, President Vladimir Putin necessarily proclaimed Russia a favorite, according to the New York Times.
“We will have to be grateful to those who took this vital first step for our country and the world,” Putin said at a cupboard assembly Tuesday morning (August 11) referring to vaccine developers, according to the Associated Press.
“I know that [the vaccine] has proven effective and that bureaucracy has strong immunity,” Putin said, despite a lack of published knowledge about the first human tests of the vaccine and that complex human trials are not being conducted lately. The haste to approve the vaccine has prompted considerations from scientists in Russia and that only conscientiously designed human trials, which come with thousands of people, can obviously show that a vaccine is safe and effective enough for public use.

“Accelerated approval will not make Russia the leader in the [vaccine] race, it will only disclose unnecessary danger to vaccine users,” the Russian Association of Clinical Trial Organizations said Monday (The Associated Press reported.
“It is not imaginable to know whether the Russian vaccine has proven effective without presenting clinical articles for research and then possibly there would be disorders with the quality of knowledge,” said Keith Neal, emeritus professor of infectious disease epidemiology at the University of Nottingham in England. in a publication at Science Media Center, an organization that provides specialized observation on clinical studies and news coverage. The first human testing of the Russian vaccine began in mid-June and included 76 participants, but no knowledge of these trials was published, according to the Associated Press.
Beyond this lack of transparency, scientists are involved in a “phase 3” clinical trial, the final level of verification required for a vaccine to be approved.
Phase 1 and 2 trials come with a few hundred participants and check whether a vaccine causes an immune reaction without triggering harmful side effects in the short term, Live Science has already reported. Although these early trials provide information on the efficacy of a vaccine, only Phase 3 trials, which include thousands to tens of thousands of volunteers, can compare infection rates among vaccinated and unvaccinated people.
In other words, only phase 3 trials can show that a vaccine prevents COVID-19 infection. To approve a vaccine in the United States, the Food and Drug Administration (FDA) is ordering a COVID-19 vaccine to decrease a user’s chances of inflamed with the virus through at least part of a placebo or an inert injection.

Russia plans to start testing its already approved vaccine on August 12, kirill Dmitriev, managing director of the Russian Direct Investment Fund (RDIF), told reporters, according to the Associated Press. (RDIF funded the progression of the vaccine). The Phase 3 trial will come with “several thousand” of participants from the United Arab Emirates, Saudi Arabia, the Philippines and in all likelihood Brazil, Dmitriev said. But before the knowledge of the trial becomes available, Russia will offer the vaccine to tens of thousands of people, he added.
“People outdoors in clinical trials will have access to the vaccine in August, and some, already on a giant scale, in October,” Dmitriev said. Specifically, Deputy Prime Minister Tatyana Golikova said doctors can start getting vaccinated this month, according to the Associated Press. Russian Health Minister Mikhail Murashko said the country would soon begin a massive crusade to distribute the vaccine and that medical staff and teachers would prioritise it first, the New York Times reported.
Without Phase 3 data, however, there is no way to know that the vaccine will outperform other people who get it to the maximum; In addition, rare side effects related to the vaccine can only occur when more and more people get the injection.
Due to their short duration of only a few months, Phase 1 and 2 trials are more useful for reading non-unusual short-term side effects, such as redness, mild fever and swelling or pain at the injection site. the informed past. One of Putin’s daughters participated in a first Sputnik V test and had a brief fever after the injection, according to the Associated Press.

Short-term effects, such as fever, occur when a vaccine stimulates the immune formula; However, some side effects may only appear once a vaccinated user encounters the coronavirus in their real life.
One such side effect is known as antiframe-dependent strengthening (EAD), a phenomenon that paradoxically makes the framework more vulnerable to infection after vaccination, Live Science has already reported. Candidate vaccines for animal coronaviruses and SARS-CoV, which caused outbreaks of severe acute respiratory syndrome in the 2000s, have caused EAD-type effects on animals, allowing a COVID-19 vaccine to do the same. Evidence of EAD may emerge in animal studies before a vaccine reaches humans, but it can also appear in Phase 3 trials, as more participants are most likely exposed to the virus in as giant trials as previous ones.
“A sign of EIM, or a similar problem, would be if other people who won the vaccine in the trials had higher COVID-19 attack rates than other people who won the placebo,” meaning that the virus is more likely to infect the vaccinated group, Dr. Sarah George, associate professor of infectious diseases and immunology at St. Louis. WordsSideKick.com told in July. Such trends would not be evident only two months after human testing, as has been done in Russia.

Although it has not shared strong evidence that its vaccine is also effective, Russia is reported to have won requests for access to Sputnik V from more than 20 countries, Dmitriev said, according to Reuters.
The questionable vaccine, developed through the Gamaleya Institute in Moscow, uses two strains of adenovirus as a basis, according to the Associated Press. Adenoviruses often cause bloodless symptoms in humans, however, those used in the vaccine have been changed to prevent the disease. After adjusting the viruses, the developers added genes that encode the coronavirus’s “peak” protein, a design that connects to cells to cause an infection, which the immune formula recognizes and uses to attack the pathogen if the frame was ever exposed.
Vaccines developed through CanSino Biologics in China and the University of Oxford and AstraZeneca in Britain use adenovirus as the basis, Live Science reported. These vaccines are lately in phase 3 trials.
