Vaccine characteristics

The Russian vaccine Gam-COVID-Vac has been developed and manufactured to prevent the development of COVID-19 infection. This is a vector combination drug.

Gam-COVID-Vac is manufactured using biotechnology, which does not imply the use of coronaviruses dangerous to humans. The drug is formed from two parts. The first contains a recombinant adenovirus vector. It serves as a transport medium.

The second part contains a vector of adenoviral particles with the same gene. This is the main part of the vaccine, it builds immunity.

Gam-COVID-Vac contains the coronavirus vector. A vector is a virus that is devoid of the ability to multiply, that is, it is harmless to humans.

Release form of the drug

The vaccine "Gam-COVID-Vak" is produced in the form of a solution for injection into the muscle of 0.5 ml. The composition is placed in bottles made of transparent glass with tight rubber stoppers. Each container is provided with a label. The vaccine is packed in cardboard boxes, each with instructions.

If the vaccine is produced by Binnopharm JSC, then the solution is packaged in 1 ml transparent glass ampoules with labels. The vaccine is placed in contour packs and cardboard boxes. There are packages with vials of 3 ml.

When frozen, the vaccine becomes a white solid mass. After thawing, it will be a colorless solution or acquire a yellow tone.

The vaccine must not be re-frozen.

The lyophilisate for making a solution also has 2 components. It is packaged in transparent bottles, tightly closed with rubber stoppers, packed in cardboard boxes, provided with an annotation.

Manufacturers of the drug

The vaccine "Gam-COVID-Vac" has the trade name "Sputnik V". Scientists around the world competed behind the scenes to see who would be the first manufacturer of a coronavirus vaccine. Russian specialists have proven their ability to work quickly and efficiently, study unknown infections and develop advanced drugs.

In addition to GU NIIEM named after N.F. Gamalei RAMS, the vaccine is produced at several other enterprises:

at the branch of the Center for Epidemiology and Microbiology named after N.F. Gamalei "Medgamal"; Binnopharm JSC; JSC "Generium".

The first component contains an active substance and additional components. The active part has adenoviral particles of the 26th serotype. The composition contains the protein S gene of the coronavirus. The auxiliary part contains magnesium chloride, polysorbate, sucrose, water for injection and other necessary substances.

The second component of the vaccine also has an active part and additional ingredients. The active part contains adenoviral recombinant parts of serotype 5. They contain the S protein gene of the coronavirus. The additional part contains the same set of substances that are in the first.

epilepsy; immunodeficiency of the primary or secondary form; diseases of the hematopoietic system; pathology of the central nervous system; chronic liver pathologies; diseases of the excretory system; diseases of the heart, blood vessels; lung pathology, for example, bronchial asthma; skin pathologies, for example, eczema, atopic dermatitis, allergic manifestations.

Before vaccination, a medical examination is carried out, the body temperature of each patient is measured. If it is more than 37 ° C, the vaccine is not given.

Side effects

With proper storage and vaccination, observance of restrictions, the vaccine against coronavirus "Gam-COVID-Vac" is well tolerated.
