Core Topic 8 Storage and handling of vaccine
Learning Outcome • To follow correct procedures for storage and handling of vaccines Immunisation Department, Centre for Infections
Learning Objectives • Describe the cold chain and the importance of its maintenance • Specify minimum/maximum temperatures for vaccine storage • Describe the effects of temperature on potency and efficacy of vaccine • Describe the requirements for the correct ordering, delivery and storage of vaccines in the workplace • Identify vaccines sensitive to light heat and freezing • Know how to manage breakdowns in the cold chain, where • to dispose of damaged vaccine, who to inform and what action to take • Explain how to audit current management of cold chain within their practice area. Immunisation Department, Centre for Infections
Cold Chain • The ‘cold chain’ is the system of transporting and storing vaccines within the safe temperature range of 2˚C to 8˚C • (Nayda C., Kempe A., Miller N. Keep it Cool: the Vaccine Cold Chain. Guidelines for Immunisation Providers on Maintaining the Cold Chain. Second edition. Commonwealth of Australia 2001) Immunisation Department, Centre for Infections
Why is the cold chain important? • Vaccines are: • Biological products • lose potency with time • Process irreversible and accelerated if proper storage conditions are not adhered to. Immunisation Department, Centre for Infections
Why is the cold chain important? • 2. Assurance/confidence in potent product and vaccine programmes • Professional responsibility • Confident the vaccines you give will be effective • Public Health responsibility • Public confidence in immunisation programmes Immunisation Department, Centre for Infections
Why is the cold chain important? • 3. Ensuring maximum benefit from immunisations • Responsibility not to waste scarce NHS resources • Reduce wastage from errors Immunisation Department, Centre for Infections
Vaccine costs and wastage • The Department of Health spends over £150 million a year on vaccines for the routine childhood programme, all of which are provided free of charge to GP surgeries and PCTs • The cost to provide vaccines for the completion of a routine childhood immunisation schedule to an individual child up to the age of 16 is over £200 • (Vaccine Update Jan 2008) • This dose not include a 3 dose course of HPV (Human Papillomavirus) vaccine! Immunisation Department, Centre for Infections
Why is the cold chain important? • 4.Compliance with SPC/Manufacturer • Any vaccine that has not been stored at a temperature of 2-8ºC as per its licensing conditions is no longer a licensed product • Responsibility/ liability rests with immunisation provider and PCT.

Sensitivity to HEAT BCG Varicella MMR MenC Hepatitis B DT and/or aP/IPV/HIB Sensitivity to COLD HepB and combination DTand/or aP/IPV/HIB Influenza MenC *MMR *Varicella *BCG (*Freeze dried) Vaccine Stability • MOST SENSITIVE • LEAST SENSITIVE Immunisation Department, Centre for Infections
Light Sensitive Sensitive to strong light, sunlight, ultraviolet, fluorescents (neon) BCG MMR Varicella Meningococcal C Conjugate Most DTaP containing vaccines • Vaccines should always be stored in their original packaging until point of use to protect them from light Immunisation Department, Centre for Infections
Vaccine Storage X No food or medical specimens X Do not place fridge in direct sunlight or near heat source X Do not remove vaccines from original boxes until ready to use X Do not store vaccines in fridge doors or in solid plastic trays/containers within the fridge X Keep vaccines away from fridge walls and cold air vents • Use a dedicated vaccine fridge • Safeguard electricity supply • No more than 50% full • Place vaccines in clearly labelled plastic mesh baskets • Group vaccines by type (Paediatric, Adult, Adolescent) • Defrost/calibrate fridge regularly • Ensure back up facilities are available in the event of fridge failing • Picture taken from www.medisave.co.uk Immunisation Department, Centre for Infections
Temperature Monitoring • Use max/min thermometer • Probe should be placed in the centre of fridge • Temperature should be recorded at least once a day • Reset daily • Calibrate as recommended • Take immediate action if temperature is outside recommended range Immunisation Department, Centre for Infections
Sample refrigerator temperature record chart • Available at: http://www2.cdc.gov/nip/isd/immtoolkit/content/vacstorage/logs.htm Immunisation Department, Centre for Infections
Storage temperature • Never exceed 8ºC or fall below 2ºC • Aim for 5ºC • Aim to maintain vaccine fridge as close as possible to 5˚C as this gives a safety margin of + or – 3˚c Immunisation Department, Centre for Infections
Ordering and Delivery • Named trained designated person and deputy who haveoverall responsibility for ordering, receipt and care of vaccines. • Responsibilities include: • Ensuring cold chain has been maintained during transport and managing receipt of vaccines directly into refrigeration • Checking delivery for leakage, damage and discrepancies • Rotation of stock • Maintaining stock information system to keep track of orders, expiry dates and running total of vaccines • Ensuring adequate supply/ Minimising over ordering or stockpiling Immunisation Department, Centre for Infections
Risks of excess stock • Over-Packed • Fridge • Poor Air • Flow • Poor Storage • Rotation • Freezing • Increased Risk • of using out of • date Stock • Sub-Optimal • Vaccines • Increased • Waste • Unprotected • patient • Increased Cost • To Clinic Immunisation Department, Centre for Infections
Cool Boxes and Transporting vaccines • Use a validated cool box and ice packs from recognised medical supply company • Monitor maximum/minimum temperature, recording at regular intervals • Vaccines should be wrapped in bubble wrap or similar insulation material to prevent direct contact with ice packs • Use insulating material to fill any spaces within the cool box • Only take enough vaccine for particular session and minimise exposure of the vaccines to room temperatures Immunisation Department, Centre for Infections
What to do if there has been a Cold Chain failure • Prior to administration • Any vaccine that has not been stored at a temperature of 2-8ºC as per its licensing conditions is no longer a licensed product • Where there is any doubt that cold chain has not been maintained, vaccines should not be used until further advice has been sought from the vaccine manufacturer • Written procedure for the disposal of vaccines by incineration should be available locally Immunisation Department, Centre for Infections
Post administration • Treat as Serious Untoward Incident • Inform Practice Manager/Line Manager/PCT of the incident • Suspend all immunisation clinics until resolved Immunisation Department, Centre for Infections
Best practice in Cold Chain compliance • Defined local policies should be in place and written in accordance with PGDs, SPCs, DH ‘Green Book’ • Regular audit of current practice • Training • Local multidisciplinary support Immunisation Department, Centre for Infections
Useful resources • Chapter 3&4 Green Book: “Storage, distribution and disposal of vaccines” and “Immunisation Procedures” • Poster and plug stickers available to order from DH publications orderline (www.dh.gov.uk) • CDC Vaccine Storage and Handling Toolkit http://www2a.cdc.gov/vaccines/ed/shtoolkit/ • WHO.
