Moderna announced today that it’s asking the FDA to authorize its COVID vaccine for children under 6 years old. The pharmaceutical company says its vaccine is about 40-50% effective at preventing symptomatic COVID-19 during its trials. 

The CDC has also issued an alert in Alabama after a cluster of hepatitis cases in young children was reported. It’s unclear where the cases originated from.
