COVID Vaccine
Why was the “world’s first” Covid-19 vaccination met with widespread scepticism?
Russia’s first covid vaccine was created by Moscow’s Gamaleya Research Institute in partnership with the Russian Defense Ministry and based on the DNA of a SARS-CoV-2 type adenovirus.
President of Russia Mr Vladimir Putin said that Russia is the first country who give regulatory permission to the Covid-19 vaccination known as ‘Sputnik V,’ raising concern among vaccine specialists who believe the government is cutting corners and putting citizens at risk.
Putin claims that the vaccine provides “durable protection” to Covid-19 and that one of his daughters received the vaccine and felt better as a result.
The vaccine is created by Moscow’s Gamaleya Research Institute in partnership with the Russian Defense Ministry.
Based on the DNA of a SARS-CoV-2 type adenovirus.
The world’s concern about the safety and effectiveness of Russia’s quick vaccination arises from the fact that it approved without phase-3 human trials, which is generally required before regulatory approval and even rushed phase-1 and phase-2 trials, which were all completed in less than two months.
“I’m worried that Russia is cutting corners, so the vaccine that will come out maybe not only ineffective but also unsafe,” said Lawrence Gostin, a global public health law expert at Georgetown University. That isn’t how it works. The trials must come first.”

Human clinical trials are essential for vaccine development.
Clinical trials are essential for a vaccine’s approval because they establish its effectiveness and security. They also help determine the best route of administration, the number of boosters required at vaccination intervals, and the duration of immunity.
Clinical development divided into three stages.
Small groups of people are given the experimental vaccine during phase 1.
In phase 2, the clinical trial enlarged, and the vaccine given to persons who have similar features (such as age and physical health) to those who will benefit from the new vaccine.
Thousands of people are given the vaccine in phase three, and it examined for efficacy and safety.
Human clinical trials are important for vaccine development.
A vaccine’s testing, manufacture, and approval are often a lengthy and difficult procedure that takes anywhere from 10 to 15 years. Vaccine experiments are being accelerated around the world due to the current urgency. This speeding up, however, does not imply sacrificing safety by skipping clinical testing steps.
“One cannot talk about vaccine approval for the public without examining the long-term safety and efficacy of the vaccine on a large number of patients,” Arun Bhatt, consultant, clinical research and therapy development, said of the importance of phase-3 clinical trials.

The phase one human trials began on June 17, according to news reports.
Phase 2 studies began on July 13 and expected to be finished within a few months.
On August 2, the Gamaleya Institute announced the successful completion of clinical testing.
Only the results of phase I of the clinical studies have been made public by Russia thus far. There is no information on whether all three phases of clinical trials were completed or only phased 2. Russia claimed that the super fast vaccine could make it possible because its Covid-19 vaccine candidate was very similar to a Middle East Respiratory Syndrome (MERS) disease caused by another coronavirus and had already extensively tested.
During his testimony before a group of US lawmakers, Dr Anthony Fauci, the country’s top infectious disease specialist, questioned the fast-track method. “I sincerely hope that the Chinese and Russians thoroughly examine the vaccines before administering them to anyone. Because claiming to have a vaccine ready to distribute before testing is, at the very least, problematic,” Fauci said.
The World Health Organization warned Russia against pushing its new Coronavirus vaccine to market.
Surprisingly, Russia previously stated that it would complete phase-3 human studies after regulators approved the shot.
Russian officials have stated that mass vaccinations will begin in October.
The World Health Organization has replied to Russia’s claim by stating that it must submit a thorough examination of the vaccine’s safety data if the country wants the WHO’s stamp of approval.
Human trial data is critical for determining the vaccine’s safety, effectiveness, and long-term impact on humans. While vaccinations have few harmful side effects, they are mostly subjected to strict observation and approval methods before being released to the general public.
The novel coronavirus disease is still spreading all over the world, with over two crore cases and over 7 lakh deaths. Oxford-AstraZeneca, Moderna, and Pfizer are currently the frontrunners in the global race for the Covid-19 vaccine.
