The medicine that helps little kids stay safe from Covid might not be made anymore this fall, which is a big problem.
This means there won't be a special shot to keep those under five years old safe from getting really sick.
There is another medicine, but it's only for kids who are already not feeling well, so many won't be able to get it.
Doctors are worried because not many little kids have gotten the shots already, so this could make things worse.
