Extension of shelf life from 7 months to 9 months has been approved for Spikevax (COVID-19 vaccine Moderna)

Change to expiry

Moderna has approved a shelf-life extension for Spikevax® vaccine when stored at frozen conditions (-25°C to -15°C). Frozen vials of Spikevax® vaccine manufactured before February 2022 and with listed expiry dates up to August 2022 can be stored for 9 months as opposed to 7 months.

Full details are provided in the Moderna DHCP letter.

Implications for vaccination sites

Spikevax® vaccine is supplied thawed to all Covid-19 vaccination sites and if the extension is applicable, it will be applied by the NHS’s Specialist Pharmaceutical Logistics (SPLs) Partners prior to delivery to sites. Sites do not need to take any further action.

As a result of the 2-month frozen shelf-life extension, sites may find that the thawed expiry date at 2°C to 8°C on the carton label is later than the expiry date printed on the vial of vaccine. Please be assured that the vaccine is safe to use until the expiry date on the carton label.

For example: The thaw label on the carton could say Exp: 03/06/2022, but the vial inside the carton might say Exp:25/05/2022

Sites are not permitted to extend the shelf-life of any Spikevax® vaccine already held on-site. The existing expiry date on the thaw label on the carton must be followed. 

Vials with expiry post August 2022

All vials and cartons labelled by Moderna Biotech SL with an expiry date beyond August 2022 will already reflect the 9-month frozen shelf-life and no further action will need to be taken by the NHS or its partners.
