Moderna files for emergency use of second Covid-19 booster shot

The company said its request covered all adults over the age of 18, including for those at higher risk due to age or comorbidities

Moderna late on Thursday sought emergency use authorization from US health regulators for a second Covid-19 booster shot, as a surge in cases in some parts of the world fueled fears of another wave of the pandemic.

The US biotechnology company said its request covered all adults over the age of 18 so that the appropriate use of an additional booster dose of its vaccine, including for those at higher risk of Covid-19 due to age or comorbidities, could be determined by the Centers for Disease Control and Prevention (CDC) and healthcare providers.
