The vaccine coded SV-030721M, was evaluated by the Gamaleya Center, the Russian research institute that developed the Sputnik V vaccine, in order to meet regulatory requirements.

National Expanded Programme for Immunisation will use the vaccine in response to the fourth wave of COVID-19 infections and amid a limited supply of vaccines. This domestic manufacturing of Sputnik V will give more people access to qualified sources of vaccination.

The vaccine makes use of heterogeneous boosting, meaning that it employs two different vectors over the course of the two shots, which the developer claims to provide longer immunity than ones that use the same delivery mechanism.

The Sputnik V vaccine, the world’s first COVID-19 vaccine to be approved for use, was authorized for use in Vietnam on March 23, after AstraZeneca.

Sputnik V is one of the few COVID-19 vaccines that have a publicly available price (less than $10 a jab), and also can be stored at standard refrigerator temperatures (2-8 degrees Celsius) without the need for ultracold chain storage.
