Review the clinical scenarios below involving special populations and potential infectious exposures. Match each patient with the most appropriate next step regarding immunization or post-exposure prophylaxis.
- A 24-year-old pregnant woman (G1P0) at 30 weeks gestation, lacking varicella immunity, who was exposed to a nephew with active chickenpox 3 days ago.Administer varicella-zoster immune globulin (VZIG) as soon as possible.
- An 8-month-old infant presenting for a well-child check whose family is traveling next week to a region with an active, widespread measles outbreak.Administer one dose of the MMR vaccine now, but do not count it toward the routine childhood series.
- A 29-year-old newly hired hospital employee who reports a history of severe anaphylactic reactions after consuming products containing baker's yeast.Withhold the recombinant hepatitis B vaccine due to an absolute contraindication.
- A 52-year-old man who is currently on postoperative day 2 following an emergency splenectomy due to blunt abdominal trauma.Delay administration of encapsulated bacterial vaccines until at least 14 days post-procedure.
Cevap
Match the pregnant patient with VZIG, the infant traveling to an outbreak with an early non-counting MMR dose, the healthcare worker with a yeast allergy to withholding the hepatitis B vaccine, and the post-splenectomy patient to delaying encapsulated vaccines for 14 days.
Each pair matches a specific clinical scenario with its evidence-based immunization guideline. Pregnant women exposed to varicella require VZIG. Infants under 12 months in outbreak areas need an early, non-counting MMR dose. Anaphylaxis to baker's yeast precludes the administration of the hepatitis B vaccine. Post-splenectomy patients require a 14-day delay after emergency surgery to mount an adequate immune response to encapsulated bacterial vaccines.

Modifications to standard immunization schedules are frequently required in special populations, including pregnancy, young infants in outbreak settings, severe component allergies, and altered immunologic states like post-splenectomy.
