LOS ANGELES (KABC) -- More than 12,000 vaccination appointments scheduled for Friday in Los Angeles have been delayed because of winter weather across the country, Mayor Eric Garcetti said Thursday afternoon. At least two major shipments, totaling more than 60,000 doses, have been held up in other states because of icy roads and grounded flights amid a massive winter weather storm across large portions of the country. Officials said 26,000 doses that were supposed to arrive Tuesday are in Kentucky, and 37,000 doses intended to be used for next week's appointments are in Tennessee. "Severe weather across the country has disrupted travel and shipping nationwide, including delaying the delivery of our vaccines,'' Garcetti said Thursday while announcing the closures. "Our city is ready to administer COVID-19 vaccines swiftly, safely and equitably -- and as soon as doses arrive in Los Angeles, we will get them into people's arms immediately.''
