FDA to limit Covid shot approval to elderly, those with medical conditions

> The new framework will also require vaccine makers to conduct a randomized controlled trial before the agency signs off on a coronavirus shot for healthy people between the ages of 6 months and 64 years. When possible, the agency will “encourage manufacturers” to complete such trials after they get the agency’s approval for a vaccine for high risk groups, a potentially expensive endeavor.

I wonder about this part. Will they have time to do this if they have to release an updated vaccine annually, like the Flu?
