    Vaccine Vivian — Immunizations: Live Vaccines, Real Contraindications and the Reactions to Expect

    A low fever is not a reason to skip a shot — but pregnancy and a suppressed immune system change everything

    Vaccine Vivian, the MnemoNurse character for Immunizations: Live Vaccines, Real Contraindications and the Reactions to Expect

    Vivian checks two things before any live vaccine: is she pregnant, and is this immune system able to handle it?

    Vivian separates real contraindications from false ones. LIVE vaccines — MMR, varicella, intranasal influenza, rotavirus — are withheld in pregnancy and in significant immunosuppression, and pregnancy is avoided for about four weeks after MMR or varicella. A mild illness with a low-grade fever is NOT a reason to delay; a moderate to severe febrile illness is. A previous anaphylactic reaction to a vaccine or its components is an absolute contraindication. Expected reactions — soreness, low-grade fever, fussiness — are treated with cool compresses and antipyretics as directed, while difficulty breathing, hives or swelling after a vaccine is an emergency.

    The story arc

    1. The setup

      A parent asks whether the visit should be rescheduled because the toddler has a runny nose and a temperature of 99.8.

    2. The turn

      In the next room, a woman who is 10 weeks pregnant is due for MMR.

    3. The crisis

      A child on chemotherapy is scheduled for varicella vaccine.

    4. The save

      Vivian teaches every family the same after-visit plan: soreness and a low fever are expected; trouble breathing, hives or swelling means emergency care.
