Smallpox/monkeypox vaccine (jynneos) - 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

    Call emergency services for signs of a severe allergic reaction, including difficulty breathing, swelling of the face or throat, widespread hives, severe dizziness, or collapse.

    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

    Is any of this happening?

    Be seen today

    After an mpox exposure, contact your healthcare team promptly if you develop a new rash, skin sores, swollen lymph nodes, fever, chills, or other concerning symptoms.

    Avoid close contact with others and call ahead before attending a clinic.

    These symptoms do not necessarily mean you have mpox, but they need assessment.

    Seek urgent medical care for chest pain, significant shortness of breath, persistent fainting, or rapidly worsening symptoms.

  3. 3

    Does any of this apply?

    Book an appointment

    Contact the vaccination service during routine hours if injection-site pain or swelling is worsening rather than improving, side effects are interfering with daily life, or you are unsure when to receive the second dose.

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