Eight vaccines are in phase 1. They’re only being tested on a small number of healthy, young people.

Fourteen are in phase 2, where a larger group is being tested.

Only 7 vaccines are in phase 3, which are being tested on thousands of people.

Those are the ones you’ve heard about:   Moderna, BioEnTech and AstraZeneca.

Moderna’s trials are underway in Seattle.

The development of making a vaccine is moving at record speed.

Vaccines usually take years to develop.

For perspective, it took 7 years to develop a vaccine for polio, 9 years for measles, 9 years for measles, 15 years for HPV and 34 years for chicken pox.
