About the vaccine
The Sputnik V vaccine is being developed by Gamaleya Scientific Research Institute of Epidemiology and Microbiology along with the Russian Defence Ministry and the Russian Direct Investment Fund (RDIF) has bankrolled the project.Sputnik V uses a combination of two viral vectors adapted from the common cold-causing adenovirus, for pharmaceutical use – the adenovirus type 26 (rAd26) vector and a recombinant adenovirus type 5 (rAd5) vector. The vector carries the genetic code of the “spike” protein, which is spread across the surface of the COVID-19 -causing SARS-CoV-2 virus. This code acts as a tag for the immune system to recognize the virus if a genuine infection by the coronavirus comes along.According to a statement by the RDIF, the use of two different vectors in two separate shots achieves a more effective immune response, as compared to the use of the same vector in two shots. By using the same vector twice, the immune system launches a defence mechanism against the virus and starts to reject the drug in the second injection,The vaccine can be given to a person in two ways - frozen or lyophilised- is the process of freeze-drying a vaccine to make it more convenient to transfer and increase its shelf life. It is administered via an intramuscular injection - which is a technique used to deliver the vaccine deep into the muscles, allowing it to be absorbed into the bloodstream quickly.On Sunday, multi-disciplinary teams deployed by the Centre to 50 districts across Maharashtra, Chhattisgarh and Punjab, flagged several problems with the states’ approach to contain the spread of the coronavirus pandemic.Meanwhile, in view of increased demand for Remdesivir due to a surge in COVID-19 cases, the government banned the export of the antiviral injection and its Active Pharmaceutical Ingredients (API) has been banned till the situation improves.
