With the EUA of Johnson and Johnson’s Covid vaccine it means a second technology is being used in the U.S. to combat the COVID-19 virus.
“With Sputnik, with AstraZeneca and the J and J, they're using slightly different adenoviruses,” Daniel Griffin, MD, PhD Chief of Infectious Disease at ProHEALTH explains in this week’s episode.
“There are a number of adenoviruses. You can take an adenovirus from a chimpanzee, and that's what they're using at AstraZeneca. They took a Chimp adenovirus, the original chadox,” he told host Serena Marshall. “What the Russians are doing and I think this is clever, is they're using two different adenoviruses. One for the delivery of the initial and then a different one for the boost. And then J and J is actually just using one adenovirus, because you know, they're hoping for a one-shot, one and done vaccine.”
This week we explore:
- What we know about Adenovirus vectors
- How they differ from and are similar to the existing mRNA vaccines.
- What side-effects you should expect from a shot using Adenovirus vectors.
