1. What Ervebo is and what it is used for

  • Ervebo is a vaccine for adults who are 18 years or older.
  • Ervebo is given to protect you against Ebola, which is caused by the Zaire ebolavirus, which is a type of Ebola virus. This vaccine does not protect you against other types of Ebola virus.
  • Because Ervebo does not contain all of the Ebola viruses, it can not give you Ebola.

Healthcare professionals may recommend that you be given this vaccine in a crisis involving the spread of Ebola.

What is Ebola?

  • Ebola is a serious disease caused by viruses. If you get Ebola, you could die from the disease. Ebola can be transmitted by humans or animals that are infected with Ebola or have died from Ebola.
  • You can get Ebola through blood and body fluids such as urine, feces, saliva, vomit, sweat, breast milk, semen, and vaginal fluids from people infected with the Ebola virus.
  • You can also get Ebola through items that have been in contact with blood or body fluids from a human or animal Ebola (such as clothing or items that have been in direct contact with infection).
  • Ebola is not transmitted through air, water or food.

You will receive information from healthcare professionals and you will then decide together whether you should receive this vaccine.

2. What you need to know before you get Ervebo

You should not get Ervebo:

  • if you are allergic to Ervebo, rice, or any of the other ingredients of this vaccine (listed in section 6).

You should not receive Ervebo if any of the above applies to you. Talk to your healthcare provider if you are unsure.

Warnings and cautions

Everyone who receives this vaccine may not be protected and the time you are protected against Ebola by Ervebo is not known.

Continue to follow the recommendations of your healthcare provider to protect yourself against Ebola infection after receiving this vaccine.

Proper handwashing is the most effective way to prevent the spread of dangerous microorganisms such as the Ebola virus. It reduces the number of microorganisms on your hands and thus reduces their spread from person to person.


Suitable methods for hand washing are described below.

  • Use soap and water when your hands are soiled with dirt, blood, or other body fluids. There is no need to use antimicrobial soap to wash your hands.
  • Use alcohol-based hand sanitizer when hands are not dirty. Do not use alcohol-based hand sanitizer when your hands are soiled with dirt, blood, or other body fluids.

In the area affected by Ebola:

In an area affected by Ebola, it is important to avoid the following:

  • Contact with blood and body fluids (such as urine, feces, saliva, sweat, vomiting, breast milk, semen, and vaginal fluids).
  • Items that may have come in contact with an infected person’s blood or body fluids (such as clothing, bedding, needles, and medical equipment).
  • Funeral or funeral rituals that require the handling of the body of someone who died of Ebola.
  • Contact with bats, monkeys, or with blood, fluids, and raw meat made from these animals (bushmeat) or meat from an unknown source.
  • Contact with semen from a man who has had Ebola. You should practice safe sex until you know that the virus is gone from the sperm.

In case of rash on the skin:

If after the vaccination with Ervebo you get a rash with sore skin, cover it until it heals. Dispose of used patches and dressings, if possible in a closed container, and dispose of them in the dustbin to ensure that people with weakened immune systems or animals do not come into contact with the patches and dressings.

Talk to healthcare professionals before you receive Ervebo if you:

Have had allergic reactions to vaccines or medicines

  • If you have ever had an allergic reaction to a vaccine or medicine, talk to your healthcare provider before receiving this vaccine.

Has a weakened immune system

If your immune system is impaired (meaning your body has a poorer ability to fight disease), you may not be able to get Ervebo. Your immune system may be impaired if:

  • you have HIV – infection or AIDS,
  • you are taking certain medicines that lower the immune system, e.g. immunosuppressive drugs or corticosteroids,
  • you have cancer or problems with the blood that lowers the immune system,
  • Someone in your family has a weakened immune system.

If you think your immune system may be down, ask your healthcare provider before receiving this vaccine. If you receive the vaccine and have a weakened immune system, it may mean that the vaccine does not work as well as in someone with a normal immune system.

Have contact with sensitive people

Tell your healthcare staff if you may be in close contact with or the same household for the next 6 weeks after receiving Ervebo as:

  • infants younger than 1 year,
  • someone who may be pregnant or breastfeeding,
  • someone who has a weakened immune system.

This is because you can pass the virus in the vaccine to them through your body fluids.

Planning to donate blood

  • Do not donate blood for at least 6 weeks after receiving this vaccine.

Has contact with farm animals

  • Make sure that your blood or body fluids do not come into close contact with farm animals for at least 6 weeks after receiving this vaccine. This is because there is a risk that you pass on the virus in the vaccine to the animals.

Have fever

  • If you have a fever, talk to your healthcare provider before receiving Ervebo. The vaccination may need to be postponed until the fever has passed.
  • A mild infection, e.g. a cold, should not be a problem but talk to your healthcare provider before getting Ervebo.

Have a bleeding disorder or have easy bruising

  • Tell your healthcare provider if you have problems with bleeding or you are easily bruised. Ervebo may cause bleeding or bruising at the site where the vaccine is injected.

Test for Ebola after receiving Ervebo

  • You can test positive for the Ebola virus after receiving Ervebo. That does not mean you have Ebola. Tell healthcare professionals that you have received Ervebo. Healthcare professionals may need to take another test.

Children and young people

If you or your child are under 18, talk to your healthcare provider. It is not known if it is safe and works in children and adolescents.

Other medicines and Ervebo

Tell your healthcare provider if you are taking, have recently taken, or might take any other medicines or vaccines.

No studies have examined how other medicines or vaccines and Ervebo may affect each other. The use of Ervebo with other vaccines is not recommended.

If you are planning to receive blood or blood products

You should not be given this vaccine while you are receiving blood or blood products. Ervebo may not have as good an effect if you receive blood or blood products 3 months before or up to 1 month after vaccination.

Pregnancy and breastfeeding

  • If you are pregnant or breast-feeding, think you may be pregnant, or are planning to have a baby, ask your healthcare provider before receiving this vaccine. They will help you decide if you should be vaccinated with Ervebo.
  • You should not become pregnant within 2 months of receiving this vaccine. Women who may become pregnant should use an effective method of contraception. It is not known whether Ervebo can harm you or your fetus. It is also not known whether the vaccine can be passed on to your baby via your breast milk.
  • If you can come into close contact with, or in the same household as someone who may be pregnant or breastfeeding for 6 weeks after receiving Ervebo, tell your healthcare provider. This is because you can transmit vaccines to them through your body fluids.
