Holiday Calendar
In observance of the State and Federal holidays coming up, there will be no order processing or vaccine deliveries during the dates listed below. Order processing and deliveries will recommence the following business day following routine processing timelines and during provider’s listed days/hours of availability. Providers must update hours in myCAvax for any additional holiday or temporary closure dates to prevent shipment incidents.
- Tuesday, November 11
- Wednesday November 26 through Friday, November 28
- Monday, December 22 through Friday, January 02
CDPH strongly encourages providers to maintain enough vaccine supply to prevent vaccine outages if orders are delayed due to weather and/or carrier interruptions.
Key Notes
If vaccine inventory or accountability corrections are needed prior to order approval, VFA Program staff will notify the clinic’s Vaccine Coordinator. Please respond as soon as possible to prevent delays in order approval. Orders needing correction will be held in queue until requested corrections are resolved or orders will expire after 2 weeks of pending corrections.
Delivery windows are dependent on provider’s days/hours of operation. Update hours in myCAvax for any holiday or temporary closure
