How do COVID-19 Viral Vector Vaccines Work?


Weakened adenoviruses can be used to deliver instructions to make the SARS-CoV-2 spike protein, educating the immune system and preparing it for future encounters with SARS-CoV-2.

The Johnson & Johnson, Astrazeneca, and the Sputnik V vaccines all use adenovirus vector technology.
