From ABC:
The U.S. approved a new COVID-19 vaccine made by Moderna late Friday but with limits on who can use it — not a replacement for the company’s existing shot, but a second option. The new vaccine, mNexspike, is a step toward next-generation coronavirus vaccines. It’s made in a way that allows for a lower dose — a fifth of the dose of its current COVID-19 vaccine, Spikevax — by refining its immune target.
The approval “adds an important new tool to help protect people at high risk of severe disease from COVID-19,” Stephane Bancel, Moderna’s CEO, said in a statement Saturday. The Food and Drug Administration approved the new vaccine for use in all adults 65 and older, and for people age 12 to 64 who have a least one health condition that puts them at increased risk from the coronavirus.
