Build the vaccination workflow from product information and the current programme. Prepare only the product needed under the defined process, with a return-to-storage flow written in advance.
Record product and lot ID, removal from cold storage, administration time and responsible person. Get any post-opening use conditions from the product's own instructions.
For a deviation or interruption, identify affected product, preserve records and get a use decision from the authorised immunisation programme or quality lead. Do not decide from a fixed temperature or time threshold.
