Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor E.P.I Expanded Program on Immunization Objective: To reduce the morbidity and mortality among infants and children caused by the seven childhood immunizable diseases. Four Major Strategies Sustaining high routine FIC coverage of at least 90% in all provinces and cities. Sustaining the polio free country for global certification. Eliminating measles by 2008 Eliminating neonatal tetanus by 2008 Elements of EPI Target Setting (main element) Information, Education and Communication Cold chain logistic management Assessment and Evaluation of overall performance Surveillance, Studies and Research Seven (7) Childhood Immunizable Diseases Tuberculosis ( Primary Complex if less than 3 years old ) Diphteria Pertussis Neonatal Tetanus Poliomyelitis Hepatitis B Measles PD 996 : “ Providing for compulsory basic immunization for infants and children below 8 years old 1 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. Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor 3 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. Most Sensitive to Heat Most Sensitive to Cold Sensitive to Sunlight and Fluorescent light Type of Vaccine Storage Temp. OPV Measles Hepa B DPT Tetox BCG -15 to -25 C At the freezer Hours of Life after opening 8 hours 2 to 8 C Body of refrigerator 4 hours Vaccine can be stored in Refrigerator: Regional – 6 months Municipal / City – 3 months Main Health Center – 1 months Transport Box : 5 days Note: 3 trip in transport box with the same vaccine discard it 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 Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor Types of Vaccine Wastage Vaccine wastage in unopened vials Expiry Heat exposure Freezing Breakage Missing inventory Theft Discarding unused vials returned from an outreach session Vaccine wastage in opened vials Discarding remaining doses at end of session Not being able to draw the number of doses indicated on the label of a vial Poor reconstitution practices Submergence of opened vials in water Suspected contamination Patient reaction requiring more than one dose Wastage Factor: ( constant ) DPT OPV Measles BCG HepB Tetox = = = = = = 1.67 1.67 2 2.5 1.10 1.67 4 Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor 5 Target Setting Steps and examples in calculating vaccine requirements Steps BCG Infant DPT Hep B 3,000 3,000 3,000 3,000 90 90 90 105 1 3 3 2 TVR = EP x number of doses 90 270 270 210 Given wastage factor (constant ) 2.5 1.67 1.1 1.67 AVR = TVR x WF 225 451 297 351 20 10 or 20 1 or 10 10 or 20 12 46 or 23 297 or 30 36 or 18 MVR = AVR / 12 months 19 38 25 29 MVA = AVA / 12 1 4 or 2 25 or 2.5 3 or 1.5 Formula Total Population ( TP ) e.g 3,000 Determine the Eligible Population ( EP ) EP = TP x 3% (Infants/Children) Mothers Tetox EP = TP x 3.5 % ( Mothers ) Required number of doses to immunize a child/ mother Determine the total vaccine required ( TVR ) Wastage Factor ( WF ) Calculate the Annual Vaccine doses required ( AVR ) Number of doses per ampule/vial Determine Annual Vaccine Ampule/Vial required ( AVA ) Caculate the Monthly Vaccine doses Required ( MVR ) Determine Monthly Vaccine Ampule/Vial required ( MVA) AVA = AVR / # of doses per ampule/vial Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor 6 EPI VACCINES BCG ( Bacille Calmette-Guerin ) Vaccine Type of Vaccine Form of Vaccine Minimum Age at 1st Dose Number of Doses to Complete the Immunization Reason Number of Doses per Ampule Dosage Route of Administration Site of Administration Storage Temperature Special Precautions Side Effect Undesired Effect Contraindication Health Teaching Live Bacterial Freeze dried Birth or anytime at birth 1st dose : at birth 2nd dose: school entrance BCG given at earliest possible age protects the possibility of TB meningitis and other TB infectious in which infants are prone. 20 ( 20 children ) At birth : 0.05 ml At school entrance : 0.10 ml Intradermal ( a special syringe and needle is used for the administration of BCG vaccine ) Right deltoid region of the arm 2 C to 8 C ( in the body or refrigerator ) Note: Freezing does not damage it but ampules may break. Diluents should also be kept cold before using Correct ID administration is essential. A special syringe and needle is used for the administration of BCG vaccine A wheal formation Koch phenomenon ( inflammatory reaction 2-4 days ) Indolent ulceration Abscess on the injection site Enlarged lymph nodes Note: Swollen glands or abscesses occur because an unsterile needle or syringe was used, too much vaccine was injected or most commonly, the vaccine was injected incorrectly under the skin instead of its top layer. Immunosuppressed indvidual due to malignant disease ( child with clinical AIDS ) ; therapy with immunosuppressive agent or radiation. Do not massage the area of injection A scar will formed 12 weeks after injection Repeat BCG vaccination if the child does not develop a scar after first injection Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor 7 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 Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor 8 DPT ( Diphteria-Pertussis-Tetanus ) Vaccine Type of Vaccine Diphteria and Tetanus as “toxiods” which is a weakened toxin Pertussis as killed whole-cell bacterium Liquid vaccine 6 weeks 3 Form of Vaccine Minimum Age at 1st Dose Number of Doses to Complete the Immunization 4 weeks / minimum of 28 days Interval An early start with DPT reduces the chance of severe Reason pertussis 20 or 10 Number of Doses per Ampule 0.5 ml Dosage Intramuscular Route of Administration Upper outer portion of the thigh ( Vastus lateralis ) in Site of Administration infant ( R – L – R ) Outer upper arm if older 2 C to 8 C ( in the body of refrigerator ) Storage Temperature Note: “DT” component is damage by freezing “P” component is damage by heat DPT not usually given over 6 years of age Special Precautions Side Effect Fever in the evening after receiving the injection. Soreness, children may have pain, redness or swelling at the injection site. Contraindication 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. Health Teaching If the child has fever give paracetamol or any appropriate antipyretic at the time and at four and eight hours after immunization. Alternating cold compress for 24 hours to warm compress if there is pain and soreness . Giving DPT Vaccine Ask mother to hold the child across her knees so that her thigh is facing upwards. Ask her to hold child’s leg. Clean the skin with a cotton ball, moistened with water and let skin dry. Grasp the injection site with your thumb and index finger. Quickly push the needle, going deep in to the muscle. Slightly pull the needle back to be sure it is not into a vein. Inject the vaccine, withdraw the needle and press the injection spot quickly with a piece of cotton.

Children known to have rare congenital immune deficiency syndrome should receive IPV ( injectable polio vaccine ) rather OPV Causes almost no side-effects. Less than 1% of the people who receive the vaccine develop a headache, diarrhea or muscle pain. None 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 Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor 10 Hepatitis B Vaccine Type of Vaccine Form of Vaccine Minimum Age at 1st Dose Number of Doses to Complete the Immunization Interval Reason Number of Doses per Ampule Dosage Route of Administration Site of Administration Storage Temperature Special Precautions Side Effect Contraindication Health Teaching “Monovalent vaccine” contain only one antigen Cloudy liquid vaccine At birth 3 6 weeks interval from 1st dose to 2nd dose 8 weeks interval from 2nd dose to 3rd dose An early start of Hep B vaccine reduces the chance of being infected and becoming a carrier.

Contraindication Severe reaction to previous dose Pregnancy Congenital or acquired immune disorder Health Teaching If the child has fever give paracetamol or any appropriate antipyretic at the time and at four and eight hours after immunization. Alternating cold compress for 24 hours to warm compress if there is pain and soreness . It also prevent diarrhea Lecture Notes on EPI (Expanded Program on Immunization) Prepared By: Mark Fredderick R Abejo R.N, MAN Clinical Instructor 12 Reconstituting the Freeze Dried Measles Vaccine Using a 10 ml. syringe fitted with a long needle, aspirate 5 ml of special diluent, from the ampule. Empty the diluent from the syringe into the vial with the vaccine. Thoroughly mix the diluent and vaccine by drawing the mixture back into the syringe and expelling it slowly into the vial several times. Do not shake the vial. Protect reconstituted measles vaccine from sunlight. Wrap vial in foil. Place the reconstituted vaccine in the slit of the foam provided in the vaccine carrier. Giving Measles Vaccine Ask the mother to hold the child firmly. Clean the skin with a cotton ball, moistened with water and let the skin dry. With the finger of one hand, pinch up the skin on the outer side of the upper arm. Without touching the needle, push the needle into the pinched-up skin so that it is not pointing. Slightly pull the plunger back to make sure that the vaccine is not injected into a vein. Press the plunger gently and inject. Withdraw the needle and press the injection spot quickly with a piece of cotton.

The best injection site for a woman is outer side of the upper arm. Quickly push the needle, going deep in to the muscle. Slightly pull the needle back to be sure it is not into a vein. Inject the vaccine, withdraw the needle and press the injection spot quickly with a piece of cotton. 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.
