You're listening to TED Talks Daily. I'm Elise Hugh. We're waiting on a coronavirus vaccine

in hopes that it can snap life back into the way things were, at least kind of. But in global

That's the French word for hydro-alcoholic gel.

She actually pronounces it better than I do. But no one wants to be

we keep thinking of the vaccine discovery like it's the

holy grail. But there are a couple of shortcuts here that I'd like to unpack. I'm not a doctor.

I'm just a consultant. My clients focus on healthcare, biopharmac companies, providers, global

health institutions, and they've educated me.

We need to find the tools to fight COVID,

and we need to make them accessible to all.

First, one single vaccine will not get us out of this.

What we need is an arsenal of tools.

We need vaccines, we need therapeutics, we need diagnostics to make sure that we can prevent, identify and treat COVID cases in a variety of populations. Second, it's not just about

finding a tool. What do you think will happen when one of those clinical trials demonstrate
