Vaccines: availability, supply, shortages and use of unlicensed medicines

Information for health professionals on availability of vaccines and use of unlicensed products Vaccines: availability, supply, shortages and use of unlicensed medicines

Vaccines with UK marketing authorisation

For vaccines with a UK marketing authorisation (i.e. UK product license), information and recommendations for use are available in the ‘Green Book’ Immunisation against infectious disease (UK Health Security Agency [UKHSA]). Health professionals should monitor for updates to the Green Book; it is possible to subscribe to email alerts so you will be notified when chapters are amended.

UKHSA regularly publish Vaccine Update, describing the latest developments in vaccines and vaccination programmes in the UK including supply updates; you can subscribe to get these by email.

Summary vaccine information is available in the Diseases in Brief and Factsheets A-Z section of our website.

The manufacturer’s marketing authorisation information can be found in the Summary of Product Characteristics (SPC) on the electronic Medicines Compendium (eMC).

Vaccine shortages

Vaccine shortages occur from time to time for a variety of reasons. Health professionals who are having difficulties obtaining vaccines are encouraged to contact their supplier for more information.

When vaccine supplies are restricted, health professionals should prioritise vaccine use; an effective risk assessment will ensure vaccine recommendations are appropriate, help identify higher risk travellers, and give priority to those who are most vulnerable.

In some vaccine shortage situations, the Medicines and Healthcare products Regulatory Agency (MHRA) and the Department of Health (DH) grant approval for vaccine companies to import alternative vaccine products. These products may not have a UK marketing authorisation and preference is that they should only be used where no suitable UK 'licensed' product is available.

Health professionals who are not independent prescribers must use a Patient Specific Direction to supply or administer these products, in addition to following any local guidelines. Prescribing information, produced in English should be available from the supplier. Where, unavailable, this information should be sought directly from the manufacturer. Additional resources for guidance on prescribing products without a UK marketing authorisation can be found in the resources section below.

Updates to marketing authorisations

Changes to vaccine marketing authorisations are published on the eMC. Recommendations for the use of vaccinations are considered and made by Joint Committee on Vaccination and Immunisation (JCVI), and thereafter published in the relevant chapter of Immunisation against infectious disease the ‘Green Book’. While the JCVI meet on a regular basis, there may be a time lag between updates to the manufacturers marketing authorisation and updates being made to the Green Book. In these situations, where the Green Book and marketing authorisation differ, health professionals should make a clinical decision if they wish to follow information provided by the manufacturer.
