Contraindications to vaccinations:

•Absolute

•Temporary

Contraindications to live attenuated vaccines:Absolute:1- History of anaphylactic reactions.

2- Subsequent doses of pertussis vaccines are absolutely

contraindicated if the child gets (within 48 hours of vaccination )

• Fever (40.5º) ,

•Collapse or shock .

•Persistent crying for 3 hours without apparent cause.

•Convulsion with or without fever within 3 hours after

vaccination.Give a single dose vaccine of diphtheria + tetanus pediatric formula ( avoid pertussis component).

Contraindications to live attenuated vaccines:Absolute:

3- HIV infection is an absolute contraindication to administration of

live attenuated vaccines ( OPV & BCG).

Temporary:

1- Severe illness that needs hospitalization.Deferred immunization till the infant recovers and could be at discharge.

2- Immunosuppression.

The strategy for the vaccine delivery

The strategy for the vaccine delivery:

(I) The fixed site strategy.

(II) Outreach site strategy.

(III) Mopping up Immunization.

(IV) The National Immunization Days (NIDs).

1. The fixed site strategy:

There is integration of immunization services through (MCH): Advantages:-

1-Available resources.

2- Cold Chain maintenance.

3- Save ,time, effort and money.

2.The out reach Strategy The outreach is carried for routine immunization that is compulsory

for the targets in certain areas where:

- immunization services are not accessible.

- vaccination coverage is Low.

Limitations:

(i) Expensive

(ii) Cold chain failure.

(iii) Difficulty to arrange the immunization schedule.

(Outreach immunization

(3) Mopping up Immunization:

• It is house-to-house immunization with OPV in high risk districts.

• High risk districts are those:

• Where the wild polio virus is still circulating

• With low immunization coverage.

• Population, with overcrowding poor sanitary environment

and low access to health services.

(4) The National Immunization Days (NIDs):

It is periodic immunization of all the eligible targets in a defined

group over a large geographic areas within a short period of time. It

is one of the strategy for polio eradication and tetanus elimination.

The cold chain

The cold chain:

It is the system of storage and transportation of the

vaccine at low temperature (cold condition) from the

manufacture till it is consumed.

The cold chain:

• Polio vaccine is the most sensitive vaccine to heat.

• Live attenuated vaccines are allowed to be frozen (OPV,

Measles and BCG).

• Inactivated vaccines must not be frozen ( DPT, DT, dT , TT

and HB) .

-To stabilize the temperature of the refrigerator at the

- Fully frozen ice-packs are used for lining the vaccines

carriers and the cold boxes during storing the vaccines

The refrigerator :

• Placed in the coolest place of the health centers away from sunlight

• Well ventilated and adequate air circulation around it .

• Kept locked and open only when necessary.

•Ice packs are kept in the freezer.

• Its temperature is recorded twice daily.

• Both the monitor and thermometer are placed in the refrigerator.

• The temperature chart is stuck on the door outside the refrigerator.

• The diluents should be kept on the lowest shelf.

• Drugs, drinks or food must not be stored in the refrigerator

Tools for monitoring the cold chain

Tools for monitoring the cold chain:

1- Cold Chain Monitor Card.

2- Freeze Watch Indicator

3- Cold Chain Refrigerator Graph

4- Vaccine Vial Monitors

5- Shake Test

Cold Chain Refrigerator Graph The vaccines are stored in refrigerators, they are monitored twice a day and readings are recorded on a chart to ensure a safe temperature is maintained

+2°C

+8°C

2-Cold Chain Monitor Card: is used to show cumulative exposure to Temp. above the safe range during storage& transportation.

2-Cold Chain Monitor Card:

3-Vaccine vial monitors:

Every vial is also shipped with a

temperature-sensitive label, that health

workers monitor during vaccination

sessions.

SAFEIf the inner square is lighter than the outer

ring and the expiration date is valid, the

vaccine is usable

SPOILEDIf the inner square

matches or is darker than the outer ring, the vaccine must be

discarded.

4-The shake test

DPT, hepatitis B and

tetanus toxoid vaccines

can all be damaged by

freezing. By shaking two

vials, side-by-side, one

that might have been

frozen and one that has

never been frozen, health

workers can determine if a

vaccine has spoiled.

What damage the Vaccines?

1. Any defect in the cold chain.

2. Out date expiry.

3. Exposure of the vaccine to unacceptable temperature

during the immunization session.

4. Exposure of the vaccine to direct sunlight (BCG)
