Varicella (chickenpox) vaccine - what you need to know: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Seek emergency help immediately for trouble breathing, swelling of the face or throat, widespread hives, severe weakness, collapse, or other signs of a serious allergic reaction.

    A seizure, severe confusion, difficulty waking, or major breathing difficulty also needs emergency assessment.

    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous
  2. 2

    Does any of this apply?

    Book an appointment

    Routine arm soreness, mild tiredness, or a low fever can usually be monitored at home.

    If you are uncertain, contact the clinic that gave the vaccine.

Every sign above is quoted from the sofidex article on Varicella (chickenpox) vaccine - what you need to know. If you are not sure, err upward — it is always reasonable to be checked.
