As Covid cases among children continue to rise in the US due to spread of the Delta variant, experts are urging the federal government to fast-track vaccine approval for those under the age of 12.

New data analysis from the American Academy of Pediatrics (AAP) indicated that children accounted for 15% of new cases reported last week, with a total of almost 94,000 cases. There was a 4% increase in child cases over the past two weeks, the AAP found.

All of this was likely unnecessary if we as adults did what we needed to do and get the vaccine. We could have protected these children.

School districts in Florida and Texas are bucking their Republican governors' bans on requiring masks for children and teachers as coronavirus cases soar in conservative areas with low vaccination rates, Reuters reports.

The Broward County school board in Florida on Tuesday became the latest major district to flout an order by the governor Rick DeSantis outlawing mask requirements in that state. The Dallas Independent School District said late Monday that it would also require masks, despite an order banning such mandates from the governor Greg Abbott.
