Examiners frequently confuse FEFO with FIFO to test attention to detail. Memorize: in EPI it is FEFO — expiry date drives the order, not the date of receipt.

Model Answer

FEFO stands for First Expiry, First Out — vaccines with the nearest expiry date must be used first.

The key differentiator is TIMING, not the vaccines themselves. Both FIC and CIC receive the same vaccines; what differs is whether they completed them before or after the first birthday. Make the timing explicit in your answer.

Model Answer

A Fully Immunized Child (FIC) is a child who has received all required EPI antigens BEFORE reaching 12 months of age. A Completely Immunized Child (CIC) is a child who received all the required doses but completed them AFTER the first birthday (between 12 and 23 months). FIC status is the program goal because on-time immunization provides protection during the highest-risk months of infancy.

BCG has THREE unique features that examiners test: (1) intradermal route — the ONLY ID vaccine, (2) 0.05 mL — smallest dose in EPI, and (3) right upper arm — site-specific. A complete answer mentions all three.

Model Answer

BCG vaccine is given via the INTRADERMAL (ID) route at a dose of 0.05 mL. The correct injection site is the RIGHT UPPER ARM (over the deltoid region). BCG is the only intradermal vaccine in the EPI schedule. A small wheal should appear upon injection, and a small scar is the expected outcome — this is NOT a sign of infection.

Scenario questions test decision-making. Examiners want to see: (1) the CORRECT decision, (2) the REASON (EPI principle), and (3) the SPECIFIC APPLICATION (which vaccines). Always include all three layers.

Model Answer

The midwife should PROCEED WITH IMMUNIZATION. Mild illness such as cough and colds is NOT a true contraindication to vaccination. The EPI program is clear: it is safe and effective to immunize a mildly sick child. Turning the child away would be a MISSED OPPORTUNITY for immunization, which could leave the child unprotected during a vulnerable period. The midwife should explain to the mother that the vaccines are safe to give alongside mild illness and that the child's condition will not worsen because of the vaccine. The child should receive all EPI vaccines due at 4 months of age (Pentavalent 2, OPV 2, and PCV 2).

Question Type

Answer Structure

• State the correct action: proceed with immunization [1 mark]

The shake test is ONLY for freeze-sensitive vaccines. A common examiner trap is asking about BCG or OPV — the shake test does not apply to them. Always connect the test to the correct vaccine category.

Model Answer

The shake test is used to check if a freeze-sensitive vaccine has been accidentally frozen and damaged. It is used for: Hepatitis B, Pentavalent (DPT-HepB-Hib), PCV, IPV, and tetanus-containing vaccines (TT/Td) — vaccines that are destroyed by freezing. Procedure: Shake the suspected vial and a known good control vial simultaneously. Observe the sedimentation. Interpretation: A POSITIVE result (vaccine is damaged) occurs when flakes or sediment appear in the vial that settle FASTER than the control vial and CANNOT be resuspended by shaking. A positive shake test means the vaccine must be DISCARDED and not used on any child.

Question Type

Remember the rule with a simple phrase: 'Square darker than ring = DISCARD.' Examiners test whether students know the action, not just the description of the VVM.

Model Answer

The Vaccine Vial Monitor (VVM) is a heat-sensitive adhesive label attached directly to a vaccine vial. Its purpose is to indicate whether the vaccine has been exposed to excessive heat and may have lost potency. How to read it: The VVM has an INNER SQUARE surrounded by an OUTER RING. As the vaccine is exposed to heat over time, the inner square gradually darkens. The midwife must CHECK THE VVM BEFORE USE: (1) If the inner square is LIGHTER than the outer ring — the vaccine is SAFE to use. (2) If the inner square is AS DARK AS or DARKER THAN the outer ring — the vaccine has been damaged by heat and must be DISCARDED immediately. The VVM does not replace twice-daily temperature recording but provides an additional vaccine-specific safeguard.

Five-mark case studies are marked in distinct parts. Structure your answer with clear headings for each vaccine. Examiners are looking for classification (freeze-sensitive vs. heat-sensitive), correct test for each, and the decisive action.

Model Answer

ASSESSMENT OF PENTAVALENT VACCINE (Freeze-sensitive): The midwife performs the SHAKE TEST on the Pentavalent vial. Procedure: She shakes the suspected Pentavalent vial and a known good (unaffected) control vial of Pentavalent simultaneously for 10–15 seconds. She then holds both vials upright side by side and observes sedimentation. Interpretation and Action: - If the suspected vial shows FLAKES or SEDIMENT that settle FASTER than the control vial and CANNOT be resuspended → POSITIVE shake test → The Pentavalent vaccine is DAMAGED and must be DISCARDED. It is NOT given to any child. - If sedimentation in the suspected vial is the same as the control → Negative shake test → The vaccine may be used. ASSESSMENT OF BCG VACCINE (Heat-sensitive, live-attenuated): BCG is a live-attenuated vaccine that is HEAT-sensitive, NOT freeze-sensitive. Freezing does NOT typically destroy BCG. Therefore, the shake test does NOT apply. For BCG, the midwife should: (1) Check the VACCINE VIAL MONITOR (VVM) — if the inner square is as dark as or darker than the outer ring, discard. (2) Check the expiry date. (3) If BCG is already reconstituted, discard it and reconstitute a fresh vial (reconstituted BCG must be used within 4 hours). (4) If the VVM is acceptable and the vial is within expiry, the BCG may be used. General Principle: Freeze-sensitive vaccines (HepB, Penta, PCV, IPV, TT/Td) are assessed using the shake test. Heat-sensitive live vaccines (OPV, BCG, MMR/MCV) are assessed using the VVM and visual inspection. The midwife must always check the refrigerator temperature chart and report the cold-chain failure to the RHU in-charge.

COMPLETE DOH ROUTINE EPI SCHEDULE (Birth to 12 Months) AT BIRTH: - BCG: 0.05 mL, Intradermal (ID), Right upper arm (deltoid) - Hepatitis B (birth dose): 0.5 mL, Intramuscular (IM), Anterolateral thigh (vastus lateralis) — must be given within 24 hours of birth AT 6 WEEKS: - Pentavalent 1 (DPT-HepB-Hib): 0.5 mL, IM, Anterolateral thigh - OPV 1 (Oral Polio Vaccine): 2 drops, Oral, Mouth - PCV 1 (Pneumococcal Conjugate Vaccine): 0.5 mL, IM, Anterolateral thigh AT 10 WEEKS: - Pentavalent 2: 0.5 mL, IM, Anterolateral thigh - OPV 2: 2 drops, Oral, Mouth - PCV 2: 0.5 mL, IM, Anterolateral thigh AT 14 WEEKS: - Pentavalent 3: 0.5 mL, IM, Anterolateral thigh - OPV 3: 2 drops, Oral, Mouth - PCV 3: 0.5 mL, IM, Anterolateral thigh - IPV 1 (Inactivated Polio Vaccine): 0.5 mL, IM, Anterolateral thigh AT 9 MONTHS: - MCV1 / MMR 1 (Measles-containing vaccine): 0.5 mL, Subcutaneous (SC), Upper outer arm - IPV 2: 0.5 mL, IM, Anterolateral thigh AT 12 MONTHS: - MCV2 / MMR 2: 0.5 mL, Subcutaneous (SC), Upper outer arm KEY NOTES: 1. The Pentavalent vaccine contains DPT + HepB + Hib in a single injection. 2. BCG is the ONLY intradermal vaccine; MMR/MCV is given subcutaneously. 3. All IM vaccines in infants go to the anterolateral thigh (vastus lateralis), NEVER the buttock. 4. Two doses of measles-containing vaccine are required because a single dose does not seroconvert every child.

Examiner Tip

The EPI program has very few true contraindications. If your answer includes fever, malnutrition, or mild illness, you are listing FALSE contraindications — a conceptual error that examiners heavily penalize.

Model Answer

True contraindications to immunization under the EPI program are: 1. ANAPHYLAXIS to a previous dose of the same vaccine or to a vaccine component (e.g., a child who developed anaphylactic shock after a dose of Pentavalent should not receive further pertussis-containing vaccines). 2. PREVIOUS SEVERE NEUROLOGICAL REACTION to DPT/Pentavalent vaccine — specifically encephalopathy occurring within 7 days of a prior dose; further pertussis-containing doses should not be given. 3. BCG is contraindicated in a child with CLINICAL SIGNS OF AIDS / SYMPTOMATIC HIV INFECTION — because BCG is a live-attenuated vaccine that can disseminate in a severely immunocompromised child. (Note: Asymptomatic HIV-positive children may still receive BCG according to DOH protocol; the contraindication is for symptomatic/clinical AIDS.)

The phrase 'NEVER RESTART the series' is almost always worth at least one mark in defaulter tracking questions. Make it prominent and clear in your answer.

Model Answer

DEFAULTER TRACKING is the systematic process of identifying children who have missed a scheduled immunization dose and actively following them up to complete the immunization series. Midwife's Role: 1. IDENTIFICATION: The midwife uses the TARGET CLIENT LIST (TCL) for immunization and the FHSIS (Field Health Services Information System) to identify children who did not come for their scheduled vaccine dose. 2. FOLLOW-UP ACTION: She conducts HOME VISITS to defaulter families, often with the help of Barangay Health Workers (BHW), to remind parents and bring children back to the BHS for their missed dose. 3. COMPLETING THE SERIES: When the defaulter returns, the midwife continues the immunization from WHERE IT WAS LEFT OFF. The series is NEVER RESTARTED from the beginning, regardless of how much time has passed. 4. RECORDING: All completed doses are recorded on the child's IMMUNIZATION CARD and on the TCL.

This question tests safety knowledge. Two key words earn marks: SCIATIC NERVE (why not buttock) and VASTUS LATERALIS (correct site). Memorize both as a pair.

Model Answer

Intramuscular injections in infants should NEVER be given in the buttock (gluteal muscle) for two reasons: (1) Risk of SCIATIC NERVE INJURY — the sciatic nerve runs close to the surface in the infant's underdeveloped gluteal region, and an injection in this area can cause permanent nerve damage and paralysis. (2) The gluteal muscle in infants has MORE SUBCUTANEOUS FAT and LESS MUSCLE MASS, which impairs vaccine absorption and reduces immunogenicity. CORRECT SITE: The ANTEROLATERAL THIGH (vastus lateralis muscle) is the preferred IM site in infants. It is the largest muscle mass available in young infants, has less overlying fat, has no major nerves or blood vessels at risk, and provides reliable vaccine absorption.

Question Type

Examiner Tip

Five-mark questions on cold chain must cover ALL dimensions: temperature, shelf placement, storage rules, reconstitution, and failure response. Write with clear numbered headings to ensure you address each dimension and make it easy for the examiner to award marks.

Model Answer

VACCINE REFRIGERATOR MANAGEMENT AT THE BHS 1. TEMPERATURE RANGE AND MONITORING: All vaccines at the BHS are stored at +2°C to +8°C. The midwife must place a thermometer INSIDE the refrigerator and record the temperature TWICE DAILY — once in the morning and once in the afternoon — on a temperature monitoring chart (cold-chain monitoring form). This allows early detection of cold-chain breaks. 2. SHELF PLACEMENT: Shelf position is based on the vaccine's sensitivity: - TOP SHELF / NEAR FREEZER COMPARTMENT: Heat-sensitive vaccines — OPV (most heat-sensitive), BCG, and Measles/MCV/MMR. These are placed closest to the cooling source to stay coldest. - MIDDLE AND LOWER SHELVES: Freeze-sensitive vaccines — Hepatitis B, Pentavalent (DPT-HepB-Hib), PCV, IPV, and Tetanus-containing vaccines (TT/Td). These must NEVER be frozen. - REFRIGERATOR DOOR: NO vaccines should be stored in the door — temperature there fluctuates most with opening and closing. 3. STORAGE RULES (CRITICAL): - Vaccines ONLY in the refrigerator — NO FOOD, NO DRINKS. Food and drinks introduce warm air and contamination. - Ice packs and water bottles may be placed inside to stabilize temperature during power outages. - Reconstituted BCG must be used within 4 HOURS; reconstituted Measles/MMR must be used within 6 HOURS. Any remaining reconstituted vaccine is DISCARDED at end of session. - Apply FEFO (First Expiry, First Out) — always use the vial nearest to expiry first. - Check the VVM (Vaccine Vial Monitor) on every vial before use. Discard if the inner square is as dark as or darker than the outer ring. - Use auto-disable (AD) syringes for every injection — one syringe per child, no recapping. 4. RESPONSE TO COLD-CHAIN FAILURE: If a cold-chain break is suspected (temperature out of range, suspected freezing), the midwife must: (1) Quarantine the affected vaccines. (2) Perform the shake test on freeze-sensitive vaccines. (3) Check VVMs. (4) Report immediately to the RHU health officer for guidance on vaccine disposal and replacement.
