Vaccines and Cold Chain

Page 16: Universal Immunization Programme

Vaccines

• Live attenuated – BCG, Measles and OPV

• Inactivated killed – DPT, TT, whole–cell pertussis, hepatitis B

• All vaccines should be stored at plus 2 to plus 8 degrees ideally in Ice Lined Refrigerators/ Domestic Refrigerators

• All government supply vaccines come with Vaccine Vial Monitors (VVMs)

• BCG and Measles vaccines are in powder form and come with diluents. Reconstitution is needed before use.

• Use reconstituted BCG and Measles vaccines within 4 hours of reconstitution and JE within 2 hours of reconstitution if kept at +2 to +8 degrees

• Use separate 5 ml syringes for each reconstitution

Page 17: Universal Immunization Programme

Cold

Why have the Cold Chain?

If vaccines are exposed to excessive

they may lose their potency or effectiveness.

Heat

Light

Page 18: Universal Immunization Programme

HEAT DAMAGE

• Heat damage is cumulative effect

• Reconstituted vaccine is most sensitive to heat and light.

• Measles and BCG vaccines should not be used 4 hrs after reconstitution and JE 2 hrs after reconstitution

• Temperature of diluents & vaccine must be same during reconstitution

Page 19: Universal Immunization Programme

Heat sensitivity

• BCG (after reconstitution)

• OPV

• Measles (before and after reconstitution)

• DPT

• BCG (before reconstitution)

• DT

• TT

• HepB

Page 21: Universal Immunization Programme

Remember

• All vaccines tend to lose potency on exposure to heat above +80 C

• Some vaccines (Hep B, TT, DPT) lose potency when exposed to freezing temperatures

• Some vaccines are sensitive to light (BCG, Measles).

• The damage is irreversible

• Physical appearance of the vaccine may remain unchanged but potency might be lost.

Page 22: Universal Immunization Programme

Vaccine carriers

• Used for carrying vaccines (16-20

vials) and diluents from PHC to the

outreach session sites.

• With 4 conditioned icepacks

maintain inside temperature of 2-80C

for 12 hours.

• Close the lid of the carrier tightly.

• Never use any day carriers with 2

icepacks or thermos flask for

carrying vaccines.

Page 23: Universal Immunization Programme

Place four conditioned Ice-Packs against the sides of the carrier

Place the plastic bag containing all vaccines and diluents in the centre of the carrier.

Fill the Ice-Pack with water to mark. Check water level before every use. Do NOT add salt to this water.

Fit the stopper and screw on the cap tightly

Make sure the Ice-Pack does not leak

Wipe the Ice-Pack dry and place in the Deep Freezer

Prepare Ice-Packs for Freezing

Place frozen Ice-Packs in the open till they “sweat,” (some condensation or droplets of water)

Check if an Ice-Pack has been conditioned by shaking it and listening for water

Unconditioned Ice-Packs may damage freeze sensitive vaccines (DPT, DT,TT and Hepatitis B)

Condition Frozen Ice-Packs

Pack the Vaccine Carrier

1 2

3

Collect vaccines in the carrier on the session day (Vaccine carriers may not store vaccines effectively beyond 12 hrs)

Do not drop or sit on the vaccine carrier.

Do not leave in sunlight. Keep in shade.

Do not leave the lid open once packed.

4 Remember to..

Correct Packing of the Vaccine Carrier

Page 26: Universal Immunization Programme

Domestic Refrigerators

• Only in urban areas with assured electric supply

• Hold over time (time taken in absence of power to raise temperature from minimum i.e. +2 degrees to maximum i.e. +8 degrees for an equipment) for a domestic refrigerator is only four hours

• Specific order of storing ice packs and vaccines in domestic refrigerator

Page 27: Universal Immunization Programme

Storing vaccines in Domestic Refrigerator

• Ice packs and OPV in freezer

• Block door panels (where bottles are stored) and vegetable tray at the bottom with thermocol

• Measles vaccine may be stored in the chiller tray below the freezer followed by T – series vaccines in the shelves below

• Hepatitis B should be stored below all vaccines

Usable and Unusable stages of VVM

Page 29: Universal Immunization Programme

Safe vaccines and waste disposal

Page 30: Universal Immunization Programme

Safe Injections • Cover any small cuts on the service provider’s skin. • Wash or disinfect hands prior to preparing injection material. • Always use an Auto Disable Syringe (ADS) for each injection

and a new disposable syringe to reconstitute each vial of BCG and measles

• Avoid giving injections if the skin of the recipient is infected or compromised by local infection (such as a skin lesion, cut, or weeping dermatitis)

• Check expiry date and VVM before use • If the injection site is dirty, wash with clean water • Use only diluent supplied with vaccine for reconstitution • Write time of reconstitution on label - Use reconstituted

vaccines within 4 hours • Use hub cutters immediately after injection has been

administered to separate needle from syringe • Disinfect sharps and non-sharps before disposal

Page 31: Universal Immunization Programme

Simple ways to improve injection safety

• Follow product-specific recommendations for use, storage, and handling of a vaccine.

• Discard any needle that has touched any non-sterile surface. • Discard a syringe that has been punctured, torn or damaged

by exposure to moisture • Consider all used equipment as contaminated • Cut the used syringe at the hub immediately after use.

Practice safe disposal of all sharps • Deposit used sharps (needles) in a hub cutter and disinfect

before safe disposal. • Prevent needle-stick injuries. Do not recap or bend needles. • Anticipate sudden movement of child.

Page 32: Universal Immunization Programme

Adverse Events Following Immunization (AEFI)

Page 33: Universal Immunization Programme

AEFIs

AEFI is any medical incident that takes place after an immunization, causes

concern, and is believed to be caused by immunization

AEFIs need to be detected, properly managed clinically, reported,

investigated, monitored and promptly responded to for corrective interventions

Page 34: Universal Immunization Programme

AEFI…..types • Vaccine reactions (high grade fever following DPT) –

caused/precipitated by active component or one of the other components of vaccine such as adjuvant/ preservative/ stabilizer

• Program error (bacterial abscess due to unsterile injections) – caused by vaccine preparation, handling or administration

• Injection reaction (fainting spell in teenager after immunization) – caused by anxiety or pain from injection rather than due to vaccine

• Coincidental (pneumonia after pulse polio NID during winters) - event occurs after immunization but is not caused by vaccine – chance temporal association

• Unknown – cause of event cannot be determined

Page 35: Universal Immunization Programme

Common minor vaccine reactions

• Local reaction (pain, swelling and/or redness), fever and systemic symptoms (e.g. vomiting, diarrhea, malaise) can result as a part of the immune response.

• Local reactions and fever should be anticipated in only 10% of the vaccine recipients, except in the case of whole cell DPT which produces fever in nearly half of those vaccinated.

• Fever and minor local and systemic reactions usually occur within a day or two of immunization (except for those produced by measles/MMR vaccine which occurs 6 to 12 days after immunization) and only last for few days.

• Fever and minor local reactions can usually be treated symptomatically with paracetamol.

Page 36: Universal Immunization Programme

Rare Serious Adverse Events Vaccine Reaction

BCG Suppurative adenitis, BCG Osteitis, Disseminated BCG infection

Hib None known

Hep B Anaphylaxis

Measles/MMR Febrile Seizures, Thrombocytopaenia, anaphylaxis

OPV Vaccine associated paralytic polio

Tetanus Brachial Neuritis, anaphylaxis, sterile abscess

DPT Persistent (>3 hrs) inconsolable crying, seizures, hypotonic hypo-responsive episode, anaphylaxis/shock

Japanese Encephalitis

Serious allergic reaction, neurological event

Page 37: Universal Immunization Programme

Reporting of AEFIs

For Immediate Reporting and Investigation • Death, hospitalization, disability or other serious and unusual

events that are thought by the public to be related to immunization

• Anaphylaxis

• Toxic shock syndrome (TSS)

• Anaphylactoid (acute hypersensitivity) reaction

• Acute Flaccid Paralysis (AFP) - Any case of AFP will be reported through the

current system for AFP surveillance and reporting

• Encephalopathy

• Sepsis

• Any event where vaccine quality is suspected

• Events occurring in a cluster

Page 38: Universal Immunization Programme

Reporting of AEFIs

• Report immediately by telephone/ fax/ messenger to PHC doctor/District Immunization Officer or Chief Medical Officer

• First Information Report format for AEFI reporting to be used

• Keep vaccines, diluents and syringes (including that used for reconstitution) for investigation

• Be vigilant for other cases

• Do not use multi dose vials further if AEFI occurs. If available use single dose vials.

Page 39: Universal Immunization Programme

Single dose vs multi dose vials

• Single dose vaccines are more costly

• Per dose cold chain space occupied is more

• Less wastage of doses if number of beneficiaries are less

• Lesser chance of AEFIs occurring due to incorrect handling

• More immunization waste generation

• Multi dose vaccines cheaper

• Reduced per dose cold chain space required

• Wastage is more if number of beneficiaries are less

• More chances of AEFI (cluster) occurring due to incorrect handling

• Less generation of immunization waste
