FDA to consider plan to cut Moderna's vaccine dose in half
The FDA is meeting this week to consider a plan to cut Moderna's vaccine dose in half.
The head of Operation Warp Speed says clinical data shows the vaccine can be just as effective in half doses for people aged 18 to 55.
Officials say that could make the vaccine available to twice as many people.
It's not clear if the same half-dose strategy would work with the other approved vaccine from Pfizer.
