– Storage
Powder: between 2 °C and 8 °C.
•  Diluent: a cold chain is not required for storage. However, at least 12 hours before reconstitution of the vaccine, the diluent must be refrigerated between 2 °C and 8 °C so that the diluent and lyophilised powder are at the same temperature: a temperature difference during reconstitution may reduce vaccine efficacy. Do not freeze.
•  Reconstituted vaccine: between 2 °C and 8 °C, for 6 hours maximum.
