1. What is IMVANEX and what is it used for
IMVANEX is a vaccine used to prevent smallpox, monkeypox, and disease caused by cowpox virus in adults and adolescents from 12 years of age.
When the vaccine is given to a person, the immune system (the body's natural defense system) produces its own protection in the form of antibodies against the smallpox virus, monkeypox virus, and cowpox viruses.
IMVANEX does not contain the smallpox virus (Variola) or the monkeypox virus or the cowpox viruses. It cannot cause or spread infection and disease caused by the smallpox virus, monkeypox virus, or cowpox viruses.
2. What you need to know before you are given IMVANEX
You should not receive IMVANEX:
- if you are allergic or have previously suffered a sudden and potentially life-threatening allergic reaction to the active substance or any of the other ingredients of this medicine (listed in section 6) or to chicken proteins, benzonase, gentamicin, or ciprofloxacin, which may be present in the vaccine in very small amounts.
Warnings and precautions
Talk to your doctor or nurse before receiving IMVANEX:
- if you have atopic dermatitis (see section 4).
- if you have an HIV infection or any other disease or treatment that weakens the immune system.
- if you are nervous about receiving the vaccine or have ever fainted after an injection with a needle.
The efficacy of IMVANEX in protecting against smallpox, monkeypox, and disease caused by cowpox virus has not been studied in humans.
In case of illness with high fever, your doctor will postpone vaccination until you are better. The presence of a minor infection, such as a cold, should not require postponement of vaccination, but consult your doctor or nurse first.
It is possible that IMVANEX may not fully protect all people who receive the vaccine.
Previous vaccination with IMVANEX may alter the skin response ("take") to subsequent smallpox vaccines with replicating viruses and cause reduced or absent take of these vaccines.
Other medicines or vaccines and IMVANEX
Tell your doctor or nurse if you are taking or have recently taken any other medicine or if you have recently received any other vaccine.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor. The use of this vaccine is not recommended during pregnancy and breastfeeding. However, your doctor will assess whether the potential benefit of preventing smallpox, monkeypox, and disease caused by cowpox virus outweighs the potential risks to you and your baby.
Driving and using machines
No information is available on the effects of IMVANEX on the ability to drive or use machines. However, if you experience any of the side effects included in section 4, some of them may affect your ability to drive or use machines (e.g., dizziness).
IMVANEX contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per dose, which is essentially "sodium-free".
3. How IMVANEX is given
You can receive this vaccine whether or not you have been vaccinated against smallpox in the past.
Your doctor or nurse will inject the vaccine under your skin, preferably in the upper arm. It should not be injected into a blood vessel.
If you have never been vaccinated against smallpox, monkeypox, or cowpox viruses:
- You will receive two injections.
- The second injection will be given no less than 28 days after the first.
- Make sure to complete the two-injection vaccination course.
If you have been previously vaccinated against smallpox, monkeypox, or cowpox viruses:
- You will receive one injection.
- If your immune system is weakened, you will receive two injections, and the second will be given no less than 28 days after the first.
If you miss an appointment for an IMVANEX injection
If you miss a scheduled injection, talk to your doctor or nurse and schedule another appointment.
If you have any other questions about the use of this vaccine, ask your doctor or nurse.
