Safe fridge range for flu vaccine

Quick check as we prep for Friday’s 9 a.m… clinic at the library: what temperature range should inactivated influenza vaccine be stored at in the refrigerator? I’m using this to gauge what to reinforce during tonight’s volunteer cold-chain refresher.

Store inactivated flu at ‘2–8°C’ (36–46°F) in the fridge — never frozen; i set the data logger to alarm at 7°C and stage the boxed vials on the middle shelf the night before the 9 a.m. library clinic so the temp is stable. If that unit tends to swing with door opens, target a 4–5°C set point as a buffer.

I usually set the fridge to hold around 5°C to give a cushion within 2–8°C, and we use a glycol‑buffered probe so door opens don’t trigger false alarms (CDC toolkit: https://www.cdc.gov/vaccines/hcp/admin/storage/toolkit/index.html). @mlane22 want us to add water bottles for thermal mass tonight or leave shelves open?
