Anaphylaxis in the vaccination setting for all vaccines
Recognising and managing anaphylaxis
The Green book provides details on the distinguishing features of an anaphylactic reaction compared to other potential reactions.
Anaphylaxis is likely when all of the following three criteria are met:
- sudden onset and rapid progression of symptoms
- life-threatening airway and/or breathing and/or circulation problems
- skin and/or mucosal changes (flushing, urticaria, angioedema)
The Resuscitation Council UK in their 2021 guidance advises that, particularly in community settings, dial 999 urgently for ambulance support and clearly state “ANAPHYLAXIS”. They also advise that all clinical staff should be able to recognise anaphylaxis, call for help and start treatment.
The Resuscitation Council UK recommend that an anaphylaxis pack should be immediately available in each location where vaccines are being given, and should not be stored in a locked cupboard or trolley. Staff should check packs regularly to ensure the contents are within their expiry dates.
The key management options for anaphylaxis are intramuscular adrenaline and oxygen. Note that antihistamines and steroids are no longer recommended for the immediate management of anaphylaxis in vaccination settings.
Use of oxygen
Additional information from the Resuscitation Council was published on 4th January 2021. It states that although oxygen is advised in the recent guidance for vaccination settings, it has not been needed for routine immunisations in the community, based on a local risk assessment. The immediate availability of oxygen is not an absolute requirement for vaccination settings.
