Context: The Russia Direct Investment Fund (RDIF), which is piloting Russia’s Sputnik V candidate vaccine, currently in Phase 3 trials, has partnered with the Hyderabad-based Dr. Reddy’s Laboratories to test, and subject to regulatory approvals in India, supply 100 million doses of the vaccine.

  • The Sputnik V vaccine, which is based on well-studied human adenoviral vector platform with proven safety, is undergoing clinical trials for the coronavirus pandemic. 

Analysis

  • Governments around the world are making a big bet that the first vaccines for COVID-19 could be made with genetically engineered viruses
  • The engineered viruses, called adenoviral vectors, are designed to shuttle a gene from SARS-CoV-2, the novel coronavirus that causes COVID-19, into our bodies where our cells will read it and make coronavirus spike proteins.
  • As with all vaccines, the idea is to trick our body into thinking it’s been infected. 
  • Those self-made spike proteins would train our bodies to detect and terminate any real SARS-CoV-2 infections before the virus wreaks havoc. 
  • The technique has been in development for more than 3 decades, but thanks to COVID-19, it is about to be put to the test like never before.
