HOW SPUTNIK V VACCINE WORKS?

 HOW SPUTNIK V VACCINE WORKS?

• Sputnik V, the vaccine against covid-19 developed by Russia, has been cleared for emergency use  by the Drug controller general of India, 
• The sputnik V vaccine, developed by Gamaleya National Research Institute of Epidemiology and Microbiology in Moscow.
• The researchers developed their vaccine from an adenovirus, a kind of virus that causes colds. they added the gene for the coronavirus spike protein to two types of adenovirus, one called ad26 and one called ad5, and engineered them so they could invade cells but no replicate. it can mount an immune response in the form of antibodies

"Once a person gets the vaccine, the vector enters a cell and uses it to make spike protein. As the immune system recognizes the spike protein and starts producing antibodies and activates other immune processes in the body."
