Immunization schedules are a high-yield topic for both pediatric board exams and general clinical practice. This article reviews essential guidelines and key vaccine contraindications.

Vaccine Contraindications (High-Yield)

  • Live Vaccines (MMR, Varicella, Rotavirus): Strictly contraindicated in severely immunocompromised individuals (e.g., severe T-cell deficiency, advanced HIV) and during pregnancy.
  • Egg Allergy: Note that standard influenza and MMR vaccines are safe to administer to patients with egg allergies, which is a common board distractor.

Catch-Up Schedules

For children who start their immunizations late, always consult the catch-up guidelines to determine the minimum interval between vaccine doses. Standard schedules cannot be accelerated beyond these parameters.
