Thinking about the nature of time right now can be pretty confusing. And you would not be

alone if you occasionally forgot what day it was. But while so much of the world has paused,

or at best slowed down to a crawl, there are places where people are sprinting.

To treat patients, to manufacture personal protective equipment, to get enough testing to the public.

These are all crucial things that need to happen.

But perhaps the most crucial is a coronavirus vaccine.

The ultimate, the ultimate solution to a virus that might keep coming back would be a vaccine.

We may have cycling with another season. We likely will have interventions, but the ultimate game changer in this will be a vaccine.

A vaccine against COVID-19 could confer immunity,

allow us to protect health care workers,

and would mean that we could really truly carve out some kind of safe version of normal.

But making a vaccine is not a speedy process.

On average, vaccines can take a decade to develop.

That's Tim Leahy. He's an infectious disease doctor and director of clinical ethics at the

University of Vermont Medical Center.

It just takes a year for the animal study. It takes a year for the phase one human trial,

a year or two for the phase two trial, and then a few years for the phase three trial.

But that typical cautious time frame doesn't work in a worldwide pandemic.

Right now, there are 60-some coronavirus vaccines in the development stage, according to the World Health Organization.

And of those, some are moving along much faster than we'd normally see. Are there currently coronavirus vaccines being tried on humans? Yes, there are three trials in the United States,

and there's a group in Oxford that's just ramping up to do a phase one clinical trial.

Does it worry you the speed at which all this is happening?
