Brief description of the problem

AstraZeneca UK Ltd. has informed the MHRA that, following routine stability analysis, the printed expiry date for the listed batches of Fluenz Tetra nasal spray suspension is incorrect. Due to the outcome of the ongoing analysis, the expiry dates for batches TH2127, TH2127B, TH3110, TH3110B, TJ2290 and TJ2290B need to be reduced by up to 5 days as a precautionary measure. The products may be safely administered up to the amended expiry date. The amended expiry dates are included in the table above.

Advice for healthcare professionals

The advice for healthcare professionals includes specific actions on continuing to use the vaccines up until the amended expiry date. Disseminate this information within 5 days, ensure any of the above batches are identified and used within the amended expiry date. After the amended expiry date, any unused products should be quarantined for return. This timeframe relates to acknowledging the information contained within the alert and ensuring that no vaccines are administered after the amended expiry date.

• Healthcare professionals, specifically those involved in the administration of this vaccine should continue to use the vaccine as directed. The vaccines may be administered safely up to the amended expiry date. Batches administered before the amended expiry date are fully effective.

• Except for the amended expiry date, there are no other changes to the product information.

• Any stock that has not been administered before the amended expiry date should be quarantined. All quarantined stock should be returned to your supplier using your supplier’s approved process.

Advice for patients and their representatives

No further action is required by patients as this is a Pharmacy and Wholesaler level recall. Fluenz Tetra is administered under the supervision of a healthcare professional. Healthcare professionals will ensure that these batches are not used after the amended expiry date; if there is any concern, discuss this alert with the administering healthcare professional. The products may be safely administered up to the amended expiry date. In the unlikely event that you receive the vaccination after the amended expiry date, it should not cause harm, but it may be less effective against one of the four strains of flu included in the vaccine.

Patients who experience adverse reactions or have any questions about the medication, should seek medical attention. Any suspected adverse reactions should also be reported via the MHRA Yellow Card scheme.
