Russian President Vladimir Putin said today that the country had registered the first vaccine against the coronavirus and the reactions have poured in. Some were skeptical while others were hopeful. Russian TV channels and other outlets praised those who worked on the project and presented the work as a major accomplishment.

But there was also caution. Although COVID-19 vaccine advancements are good news, the Russian government's urgency to win the race for the drug caused the announcement to be made with a few months of human trials and that has generated uncertainty.

The president declared to his government that the vaccine had proven its effectiveness during tests and that it had offered lasting immunity against the virus.

"I would like to repeat that it has passed all the necessary tests,” he said. “The most important thing is to ensure full safety of using the vaccine and its efficiency. He even demonstrated the quality of the drug with a family link: he said that one of his two daughters - it is unknown if it was Maria or Katerina - had been vaccinated and that she felt fine.

"She has taken part in the experiment. She’s feeling well and has high number of antibodies," Putin said.

Putin said that his daughter had a temperature of 38 degrees on the day of the first injection, that the number dropped to 37 degrees the next day and that after the second injection she had a slight rise again "and nothing else."

But the short time frame in which Russia claims to have completed the vaccine is cause for doubts for the world's specialists. Several scientists were skeptical and questioned the decision to register the vaccine before phase 3 trials, which typically last months and involve thousands of people.

They even claimed that the information on the progress of the study was not published as the tests progressed, as did the other international projects seeking the drug.

Although having shown enthusiasm days ago regarding the news, today the World Health Organization stressed the need for the vaccine to comply with all the deadlines stipulated by the organization in order to be considered.

For his part, at a press conference, another WHO spokesman, Christian Lindmeier, pointed out when the Russian Government's intentions to register it this week were known that "we have to be always careful when any such measures or highlights or reports come out".

The organization's spokesman, Tarik Jasarevic, said from Geneva as published by The Guardian: "We are in close contact with Russian health authorities and discussions are ongoing with respect to possible WHO pre-qualification of the vaccine, but again pre-qualification of any vaccine includes the rigorous review and assessment of all required safety and efficacy data."

He also indicated: "Accelerating progress should not mean compromising security."

So far the Russians have not published a detailed study of the results of their trials to establish the efficacy of the vaccine. Last week the WHO had been hesitant when Russia had stated that its vaccine was almost ready and recalled that every pharmaceutical product must undergo all the different tests and trials before being approved for use.

The Russian Coronavirus Vaccine In Detail

Human studies of the Russian vaccine, which is called Sputnik V (after the first satellite launched into space by the Soviet Union), began on June 17 with 76 volunteers., In this group, half received a dose in liquid form and the other half, in soluble powder.

What needs to be completed is phase 3, which begins tomorrow and is the one that is applied en masse to a large number of volunteers, a fact that is key for scientists when it comes to confirming the suitability of a drug.

On the official website of the vaccine, Russia assures that the vaccine completely passed all stages of pre-clinical efficacy and safety trials, which included experiments with various types of laboratory animals, including 2 species of primates. The drug has been registered and Russia assured that its effectiveness is proven despite the lack of the last phase.

Putin then explained that the phase 1 and 2 clinical trials were completed on August 1 and that all the volunteers tolerated the tests well, and did not register any serious or unexpected adverse effects, a statement that also raised questions in the international scientific community since this requires accurate and public data to support.

Against this, however, the Kremlin states said that the vaccine-induced the formation of a high cellular immune response and antibodies, and no participant in the current clinical trial has contracted the coronavirus after administration.

What happened to those who received the drug? They developed antibodies in the blood serum to neutralize the virus and immune cells that were activated in response to the protein S of the 'spines' of the coronavirus, which indicates the formation of an immune reaction, both antibody, and cellular.

The third phase of clinical trials is beginning with more than 2,000 participants in Russia and several countries in the Middle East, including the United Arab Emirates and Saudi Arabia, and from Latin America, such as Brazil and Mexico.

Russian authorities said that large-scale production of the vaccine will begin in September, and mass vaccination campaigns will begin in October. 20 countries have already requested the Russian vaccine.
