Concept and Importance of
Vaccination
Immunization – is the process by
which vaccines are introduced into the
body before infection sets in.
Vaccines are administered to
introduced immunity thereby
causing the recipient’s immune
system to react to the vaccine that
produces antibodies to fight
infection.
Vaccinations promote health and
protect children from disease –
causing agents.
Infants and newborn need to be
vaccinated at an early age since they
belong to vulnerable age group.
General Principles in
Vaccinating Children
It is safe and immunologically
effective to administer all EPI
vaccines on the same day at different
sites of the body.
The vaccination schedule should
not be restarted from the beginning
even if the interval between doses
exceeded the recommended interval
by months or year.
Giving doses of a vaccine at less
than the recommended 4 weeks
interval may lessen the antibody
response. Lengthening the interval
between doses of vaccines leads to
higher antibody levels.
No extra doses must be given to
children who missed a dose of
DPT/HB/OPV. The vaccination
must be continued as if no time had
elapsed between doses.
Lecture Notes on EPI (Expanded Program on Immunization)
Prepared By: Mark Fredderick R Abejo R.N, MAN
Clinical Instructor
Do not give more than one dose of
the same vaccine to a child in one
session. Give doses of the same
vaccine at the correct intervals.
Strictly follow the principle of
never, ever reconstituting the freeze
dried vaccine in anything other than
the diluent supplied with them.
If you are giving more than one
vaccine, do not use the same syringe
and do not use the same arm or leg
for more than one injection.
Contraindication to
Immunization
Anaphylaxis
or
severe
hypersensitivity reaction to a
previous dose of vaccine is an
absolute
contraindication
to
subsequent doses of vaccine
Person with a known allergy to a
vaccine component should not be
vaccinated.
DPT2 or DPT3 is not given to a
child who has convulsions or shock
within 3 days after DPT1. Vaccines
containing the whole cell pertussis
component should not be given to a
children with an evolving
neurological disease.
Do not give live vaccines like BCG
to
a
individuals
who
are
immunosuppressed due to malignant
disease ( child with AIDS) , going
therapy with immunosuppressive
agents or radiation.
A child with a sign and symptoms
of severe dehydration
Fever of 38.5 C and above
2
The following are NOT
contraindication. Infants with
these conditions SHOULD be
immunized:
Allergy or asthma ( except if there
is a known allergy to a specific
component of vaccine mentioned
above )
Minor respiratory tract infection
Diarrhea
Temp. below 38.5 C
Family history of adverse reaction
following immunization
Family history of convulsions,
seizures
Known or suspected HIV infection
with no signs and symptoms of
AIDS
Child being breastfed
Chronic illness such as diseases of
heart, lung, kidney or liver
Stable neurological condition such
as cerebral palsy or Down’s
Syndrome
Premature or low birthweight
(vaccination should not be
postponed )
Recent or imminent surgery
Malnutrition
History of jaundice at birth
Note:
If parent strongly objects to
an immunization for a sick infant,
do not give it. Ask the mother to
comeback when child is well.
EPI Routine Schedule
Every
Wednesday
is
designated as immunization day and is
adopted in all part of the country
FIC “Fully Immunized Child” when
a child receives one dose of BCG, 3
doses of OPV, 3 doses of DPT, 3 doses
of HepB and one dose of measles
before a child’s first birthday.

EPI COLD CHAIN and LOGISTICS
Cold Chain Manager = Public Health Nurse
Temperature monitoring of vaccines is done in all levels of health facilities to
monitor vaccine temperature.
Temperature checking is done twice a day early in the morning and in the
afternoon before going home.
Temperature is plotted every day in monitoring chart to monitor break in cold
chain.

FEFO ( first expiry and first out ) vaccine is practiced to ensure that all
vaccines are utilized before its expiry date.
Proper arrangement of vaccines and labeling of vaccines expiry date are done to
identify those near to expire vaccines
Vaccine Wastage
Wastage is defined as loss by use, decay, erosion or leakage or through
wastefulness
Wastage rate = Doses supplied – doses administered
Doses supplied
x 100

Reconstituting the freeze dried BCG Vaccine:
Always keep the diluent cold
Using a 5ml. syringe fitted with along needle, aspirate 2 ml. of saline solution from
the opened ampule of diluent.
Inject the 2ml. saline into the ampule of freeze dried BCG.
Thoroughly mix the diluent and vaccine by drawing the mixture back into the
syringe and expel it slowly into the ampule several times.
Return the reconstituted vaccine on the slit of the foam provided in the vaccine
carrier.
Giving BCG Vaccine:
Clean the skin with a cotton ball moistened with water and let skin dry.
Hold the child’s arm with your left hand so that your hand is under and your thumb
and finger come around the arm and stretch the skin.
Hold the syringe in your right hand with the bevel and the scale pointing up
towards you.
Lay the syringe and needle almost flat along the child’s arm.
Insert the tip of the needle into skin – just the bevel. Keep the needle flat along the
skin and the bevel facing upwards, so the vaccine only goes into the upper layers of
the skin.
Put your left thumb over the needle end to hold it in position. Hold the plunger e
between the index and middle fingers of the right hand and press the plunger in
with your right thumb.
If the vaccine is injected correctly into the skin, a flat wheal with the surface pitted
like an orange peel will appear at the injection site.
Withdraw needle gently.
Note:
 Any remaining reconstituted vaccine must be discarded after 6 hours or at the end
of the immunization sessions, whichever comes first.
 The small raised lump appears at the injection site, usually disappears within 30
minutes.
 After 2 weeks, a red sore forms that is about the size of the end of an unsharpened
pencil.
 The sore remains for another two weeks and then heals, a small scar, about 5mm
across remains. This is a sign that the child has been effectively immunized.
 Repeat BCG vaccination if the child does not develop a scar after the 1st injection
 BCG vaccine is moderately effective. It has a protective efficacy of:
50 % against any TB disease
64 % against TB meningitis
74 % against death from TB

Nothing by mouth (NPO) 30 minutes before and
after OPV.
Do not touch the tip dropper bottle to the tongue.
Giving Oral Polio Vaccine
Read the manufacturer’s instructions to determine number of drops to be given.
Use the dropper provided for.
Two types of OPV containers:
- small plastic dropper bottles
- glass vials with dropper in a separate plastic bag
Let the mother hold the child lying firmly on his back.
If necessary open the child’s mouth by squeezing the cheeks gently between your
fingers to make his lips point upwards.
Put drops of vaccine straight from the dropper into the child’s tongue but do not let
the dropper touch the child’s tongue.
Make sure that the child swallows the vaccine. If he spits it out, give another dose.
If a child has diarrhea when you give OPV, administer an extra dose – that is, a
fourth dose at least four weeks after he or she has received the last dose in the
schedule

Role of A Nurse In Improving the Delivery of Immunization
in the Community.
As a nurse you need to:
Actively master list infants eligible for vaccination in the community.
Immunize infants following the recommended immunization schedule, route of
administration, correct dosage and following the proper cold chain storage of
vaccines.
Observe aseptic technique on immunization and use one syringe and one needle
per child. This reduces blood-borne diseases and promote safety injection practices.
Dispose used syringes and needles properly by using collector box and disposing it
in the septic vault to prevent health hazard.
Inform, educate and communicate with the parents
 to create awareness and motivate to submit their child for vaccination.
 to provide health teachings on the importance and benefits of
immunization, importance of follow up dose to avoid defaulters and
normal course of vaccine.
 to inform immunization schedule as adopted by local units.
Conduct health visits in the community to assess other health needs of the
community and be able to provide package of health services to targets.
Identify cases of EPI target diseases per standard case definition.
Manage vaccines properly by following the recommended storage of vaccines.
Record the children given with vaccination in the Target Client list and
GECD/GMC or any standard recording form utilized.
Submit report and record of children vaccinated, cases and deaths on EPI diseases,
vaccine received and utilized and any other EPI related reports.
Identify and actively search cases and deaths of EPI target diseases following
standard case definition.
