Coronavirus expert says Americans will be wearing masks for ‘several years’

In reality I think we have a lot of tools to create a vaccine that we didn't have just a couple of years ago. I honestly hope we have a 70 percent effective vaccine by year end, and that we can produce it in enough quantity to see some results by summer. That and I hope that the immunity lasts more than a year.
