Hundreds of second-dose vaccination appointments were postponed this week in Riverside County due to supply delays caused by winter storms throughout the country, county officials said Thursday.
About 600 appointments slated for this week were rescheduled, or were in the process of being rescheduled, due to a shortage of Moderna vaccine doses, according to the Riverside University Health System.
RUHS spokesman Jose Arballo said the new appointments will be scheduled for early next week based on the “anticipated delivery” of additional Moderna doses. He said the new second-dose appointments will still fall within the 42-day time frame recommended by the Centers for Disease Control and Prevention.
The delays have not affected residents with appointments for their first doses, he said.
Weather-related delays of vaccine shipments have also forced the closure of vaccination sites in Orange County and are causing delays in vaccinations in San Diego County. The city of Los Angeles reported it will be closing its vaccination sites Friday due to the delayed shipments, although Los Angeles County says its county-run sites will remain open.
