Infectious disease prevention, immunoprophylaxis, and epidemiology in pharmacy
What the exam tests
This domain tests infection prevention in the pharmacy, vaccine handling, immunization principles, and basic epidemiology: chain of infection, transmission, outbreak response, and post-exposure management.
Core rules
- Hand hygiene, PPE, cleaning, disinfection, and safe waste disposal interrupt transmission in the pharmacy.
- Vaccines must be stored within the validated cold chain, usually +2 °C to +8 °C unless the product label states otherwise; never freeze adjuvanted vaccines.
- Follow the current national immunization calendar and the product’s package insert for dose, route, and schedule.
- Maintain an anaphylaxis kit and trained staff wherever vaccines are given.
- Needlestick and mucosal exposures require immediate washing, reporting, risk assessment, and post-exposure prophylaxis as indicated.
Worked example
The vaccine refrigerator is found at +12 °C for two hours. What should staff do?
Reasoning: do not administer the vaccines until stability is confirmed. Label the affected stock “do not use”, quarantine it, record the time and temperature, and contact the responsible pharmacist and immunization programme or manufacturer for a stability assessment. Some vaccines may remain usable after a documented excursion; others must be discarded. The decision must be documented, and the refrigerator should be checked, repaired, and monitored with a calibrated thermometer and alarm.
Traps that cost marks
- Freezing vaccines to “keep them colder”.
- Using a domestic refrigerator without temperature monitoring or a lock.
- Reusing a needle or recapping it by hand.
- Ignoring an exposure because the patient’s status is unknown.
- Giving an antihistamine instead of adrenaline for anaphylaxis.
Exam focus
State the control measure, the documentation, and the escalation route.
