## 문제

Situation: A nurse manages the National Immunization Program (NIP) at a Rural Health Unit (RHU) that serves 12 barangays.

At a session, a mother refuses the pentavalent vaccine for her 10-week-old because her first child had fever and a sore thigh after it. Which response by the nurse is BEST?

## 보기

1. Explain that these short-lived reactions are common and how to manage them **✔ 정답**
2. Give only the oral polio vaccine today, as it does not cause fever
3. Explain that the law makes the vaccine mandatory, then give it as scheduled
4. Agree to postpone the vaccine until the infant is older and stronger

**정답: 1**

## 해설

Fever and soreness after pentavalent vaccine are common, short-lived, and manageable at home, and they are not contraindications. The nurse addresses the mother's specific fear with honest information and teaching so that she can make an informed decision. If she still refuses, the nurse documents the refusal and the information given and offers the vaccine again at later visits.

## 심화 해설

Core nursing response

The best response is to acknowledge the mother’s specific concern, explain that fever and local soreness are common and self-limiting reactions, and teach simple home management. This approach respects the parent’s autonomy while addressing vaccine hesitancy with honest, evidence-informed information [1][2].

Pentavalent vaccine combines antigens against diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenzae type b. Post-immunization fever and injection-site tenderness are expected reactogenicity events, not contraindications. In a randomized controlled trial among Nigerian infants, fever occurred in a substantial proportion of recipients after pentavalent vaccination, and prophylactic acetaminophen reduced its incidence compared with no prophylaxis [1]. This supports the teaching point that fever is common and manageable rather than a reason to withhold the vaccine.

Key point! A prior sibling’s mild reaction does not contraindicate vaccination for the current infant. The mother’s fear is based on a real but benign experience, so the nurse should validate it and provide practical guidance: monitor temperature, offer fluids, apply a cool cloth to the injection site, and use acetaminophen if fever develops according to local guidelines [1][3].

Watch out! Option 2 is incorrect because giving only oral polio vaccine leaves the infant unprotected against five other serious diseases and does not address the mother’s underlying concern. Option 3 is coercive and damages trust; vaccine hesitancy research shows that perceived pressure or compulsion can reinforce resistance [2][4]. Option 4 delays protection during a period of high vulnerability and is not supported by evidence—infants do not need to be “older and stronger” to receive pentavalent vaccine safely [1].

Qualitative evidence from mothers in Northern Ghana highlights that clear communication about expected adverse events following immunization (AEFIs) and how to manage them improves trust and vaccine acceptance [3]. Similarly, a review of U.S. parental hesitancy found that parents often weigh personal stories of adverse reactions more heavily than population-level safety data, so the nurse’s individualized, empathetic explanation is more effective than simply citing mandates or statistics [4].

If the mother still refuses after teaching, the nurse documents the refusal, records the information provided, and offers the vaccine again at subsequent visits. This aligns with ethical practice and with evidence that repeated, respectful offers can eventually overcome hesitancy [2][3].

| Option | Rationale | Clinical judgment |
| --- | --- | --- |
| 1. Explain reactions and home management | Addresses fear, builds trust, enables informed decision | Best response |
| 2. Give only OPV today | Leaves infant unprotected; avoids the real issue | Incorrect |
| 3. State the law makes it mandatory | Coercive; may increase resistance | Incorrect |
| 4. Postpone until older | Unnecessary delay; no safety basis | Incorrect |

## 임상 시나리오

Managing Mild Post-Vaccination ReactionsAddressing Parental Concerns Without Delaying Immunization
Fever and injection-site soreness after the pentavalent vaccine are common, self-limiting reactogenicity events, not contraindications. They typically resolve within 24–48 hours.

A prior sibling's mild reaction does not contraindicate vaccination for the current infant. The nurse should validate the mother's concern and teach home management: monitor temperature, offer fluids, apply a cool cloth to the injection site, and use acetaminophen if fever develops according to local guidelines.

CautionDo not postpone or omit the vaccine based on a history of mild reactions. If the mother still refuses after education, document the refusal and the information given, and offer the vaccine again at later visits.

## 핵심 개념

- **Pentavalent vaccine** — Combined vaccine against diphtheria, tetanus, pertussis, hepatitis B, and Haemophilus influenzae type b.
- **Reactogenicity** — Expected local or systemic reactions after vaccination, such as fever or injection-site soreness, which are not contraindications.
- **Vaccine hesitancy** — Delay in acceptance or refusal of vaccines despite availability, often driven by concerns about safety or past experiences.
- **Informed decision** — A choice made by the parent after receiving accurate, understandable information about benefits and risks.
- **Contraindication** — A condition or factor that makes a particular treatment or procedure inadvisable; mild post-vaccination reactions are not contraindications.
