some piece of a virus to your body so you can mount an immune response

And then your immune system sees those fragments

and learns to respond to it.

[ALBERT BOURLA]: You do things in parallel.

Research, trials, manufacturing, and distribution.

[MIKE MCDERMOTT]: So if we think about how long

we would take to build our manufacturing network,

typically that would be a two to three year process.

We shrank it down to about five months.

[NATHAN VARDI]: There are some important reasons why messenger RNA

was appealing for developing a COVID-19 vaccine.

First of all, the virus itself is an RNA virus.

So it lent itself to this technology.

[PHIL DORMITZER]: In an RNA based vaccine, you simply inject the

instruction set that teaches your body how to make a piece of the virus.

[LAURIE GARRETT]: This is going to have a huge impact down the road.

[FRANK SNOWDEN]: It's wonderful….

What's happening is an extraordinary scientific breakthrough.
