Study of the Sputnik Light vaccine

A study to evaluate the effectiveness and safety of the Sputnik Light vaccine has started in Kaliningrad.

The first volunteers are examined, they signed an informed consent to participate in the study.

The participation of 150 volunteers is planned, "TASS reports from a representative of the center.

It is expected that the vaccine will arrive in Kaliningrad in the next two days, by this time the results of the analyzes of the participants in the study will be known.

Recall that on January 11, the Ministry of Health issued a permit to the center.

Gamaleya for clinical trials of the Sputnik Light vaccine.

According to the director of the center.

Gamalea, this one-component preparation will allow you to form immunity for three to four months.

Vaccination with "Kovivac"

Recall that on February 20, the third vaccine, Kovivac, was registered in Russia.

This drug was created by the Federal Scientific Center for Research and Development of Immunobiological Preparations named after M.P.

Chumakov RAS.

As the creators of the drug explained, this is a whole virion inactivated vaccine, which uses the whole inactivated SARS-CoV-2 virus.

The body is able to recognize and remember its antigenic composition. 

"In the course of clinical trials on volunteers, the vaccine has shown safety and efficacy," Russian Minister of Health Mikhail Murashko commented earlier.

Experts believe that booster vaccinations with this drug can be given every two to three years.

This point of view was expressed by the chief physician of the Leader of Medicine medical center, pediatrician, infectious disease specialist Evgeny Timakov.

He noted that the Kovivac vaccine was developed on the basis of a proven platform that has been used many times in the development of a number of other vaccines.

“Since this vaccine is made whole-virion, <...> then, in principle, any mutations of the virus that are serious can be rearranged, that is, it will be possible to take a new virus, grow it and make the production of a new vaccine on the same rails ", - said the expert on the air of the TV channel" Moscow 24 ".

At the same time, the expert believes that the use of various vaccines will be a more effective option for protecting against coronavirus.

So, according to Timakov, at the time of "strong contact with the coronavirus" should be vaccinated with the Sputnik V vaccine.

“A certain time passes, a year or two, when this vaccine is still valid, <...> and then we continue to vaccinate with just other vaccines, including the whole virion vaccine (Kovivac. -

),” the doctor said.

Vaccination of the ill

Professor of virology Alexander Chepurnov believes that in order to determine the need to get vaccinated with COVID-19, the level of antibodies should be monitored.

According to him, after a past illness, one should immediately pass an analysis for the appropriate indicator.

“The spread is colossal: after a couple of months, the antibodies begin to fade away, in someone, I know cases, after eight months the antibodies are still high,” RBC quotes Chepurnov.

The expert noted that in case of a decrease in the level of antibodies to the borderline values, you can get vaccinated.
