Although the microorganisms in the vaccine are alive, they cannot cause disease in humans because they are weakened. Oxford/AstraZeneca, Sputnik V ve Johnson & Johnson‘s vaccines are produced in a similar way.
Sinopharm’s new vaccine, on the other hand, has an efficiency of 72.5 percent, according to the company’s data. The second vaccine is an inactive vaccine, like Sinopharm’s first approved vaccine. In the inactive vaccine, which is a traditional method, the virus is killed, disintegrated and inactivated, and the immune system is stimulated without harming the body.

Trade Minister Denis Manturov stated that the price reduction is possible thanks to improvements and optimization in industrial production of the vaccine. The minister noted that the significant increase in the amount produced with the introduction of mass vaccination in Russia also played a role in the price reduction.
Manturov added that the new price will only apply to vaccination campaigns within Russia.
Sputnik V was the first registered vaccine against coronavirus in the world by obtaining a use permit in Russia in August. Russia’s consent to the vaccine before the Phase 3 research results were completed led to the international suspicion of the vaccine.
