Receiving Vaccines

Key Points 

  • Never reject or return a vaccine shipment. 
  • Open immediately and look for damage. Potency may be reduced if vaccines get too warm. 
  • Never place unopened, unpacked shipment in a vaccine storage unit as thermal shippers may expose vaccine to temperatures that are too cold. 
  • Check shipment for temperature excursions and content discrepancies before storing. 
  • Report shipment incidents in myCAvax the day shipments arrive.

Questionable Shipments

Vaccine shipments exposed to out-of-range temperatures or received outside the shipping time specified on shipper inserts must be labeled Do Not Use (PDF) and stored in vaccine refrigerators or freezers—separate from the rest of the vaccine stock—until the Provider Call Center (or VFC Call Center for VFC orders) provides additional instructions.
