An overview of the Comirnaty 30 (JN.1) vaccine and signposts to other useful resources

Presentation

Comirnaty JN.1 30 micrograms/dose dispersion for injection COVID-19 mRNA Vaccine (nucleoside modified) bretovameran is presented in multi-dose vials. We refer to it as Comirnaty 30 (JN.1) in our web articles and SOPs. The vials contain 6 doses of 0.3mL. 

Comirnaty 30 (JN.1) is thawed by the NHS’s Specialist Pharmaceutical Logistics (SPL) providers before onward supply to the NHS at 2 to 8°C. The SPLs attach a thaw label to the original carton of multidose vials. 

The thaw label applied by SPLs bears the new shelf life at 2 to 8°C. The vials inside the cartons are not labelled with the post thaw expiry date so it is essential that the vials remain within their carton until the point of removal from the fridge for immediate use. 

Further information may be found on our Ordering, receipt & storage of COVID-19 Vaccines page.

Consumables and Patient Information Leaflets

Patient Information Leaflets, and syringes and needles for administration are provided with the vaccines. 

Shelf life and storage

  • Comirnaty 30 (JN.1) may be stored for up to 10 weeks at 2 to 8°C following thawing. 
  • Within the 10 weeks, it may be stored for up to 24 hours at room temperature (between 8°C and 30°C) following removal from the refrigerator. 
  • Once punctured the vaccine is physicochemically stable for up to 12 hours at room temperature up to 30°C (within the allowed use period of 10 weeks at 2°C to 8°C and 24 hours pre-puncture at 8°C to 30°).
  • However, from a microbiological point of view, the method of puncture does not preclude the risk of microbial contamination, so the vaccine should be used as soon as practically possible e.g. within one work session which would not normally be more than 6 hours. 

Transport and movement

Unpunctured vaccine vials stored at 2 to 8°C may be transported throughout their 10-week post-thaw shelf life. 

Further information can be found in our Transport of COVID-19 vaccines article. 

Preparation

Comirnaty 30 (JN.1) is presented as a ‘ready to use’ formulation. 

Detailed advice about preparation, including a model standard operational procedure can be found on our Comirnaty 30 (JN.1) preparation page

Risk management

It is possible that Comirnaty 30 (JN.1) will be handled in the same location as other vaccines. Following the guidance on Handling multiple COVID-19 Vaccines will reduce the risk of errors. 

Licensed status

Comirnaty 30 (JN.1) has a Marketing Authorisation (PLGB) in the UK. 

Some of the vaccine vials being supplied to the UK have been labelled for the European market and so bear an EU marketing authorisation number rather than the PLGB number, and have one or more EU Patient Information Leaflets (PILs) in the carton. These vials are still considered licensed in the UK, but the EU PILs should not be given to patients. 

Allergy, excipients and dietary advice 

Comirnaty 30 (JN.1) is contraindicated in those with a hypersensitivity to the active substance or to any excipient (ingredient) in the vaccine, although revaccination may be possible on the advice of an expert (e.g. allergy specialist). See the Summary of Product Characteristics (SPC) for full details of the active substance and excipients included in the vaccine. 

Allergy to any excipient is possible, but polyethylene glycol (PEG) is of particular importance.  See the Green Book Chapter 14a: COVID-19 for details on how to manage individuals with a history of allergy. 

Comirnaty 30 (JN.1) is free from gluten, nut, soy, latex and animal products such as egg. However, as with most pharmaceutical products the manufacturer cannot guarantee that minute amounts of substances (listed previously) are not contained in raw materials from their suppliers, or that the product has not come into contact with latex during the manufacturing process.
