Contents of the pack and further information
1. What Priorix is and what it is used for
Priorix is a vaccine that is administered to children from 9 months, adolescents and adults to protect them against diseases caused by the measles, mumps and rubella viruses.
How Priorix works
When a person is vaccinated with Priorix, the immune system (the body's natural defense system) will produce antibodies to protect the person from infection with the measles, mumps and rubella viruses.
Although Priorix contains live viruses, they are too weak to cause measles, mumps or rubella in healthy people.
2. What you need to know before you are given Priorix
Priorix must not be administered if
- you are allergic to the active substances or to any of the other components of this vaccine (listed in section 6). The signs of an allergic reaction may include skin rash with itching, difficulty breathing and swelling of the face or tongue;
- you are allergic to neomycin (an antibiotic). Although a known contact dermatitis (skin rash caused by direct contact with allergens such as neomycin) should not be a problem, consult your doctor first;
- you have a severe infection with a high temperature. In these cases, vaccination will be postponed until you recover. Although a mild infection, such as a cold, should not be a problem, consult your doctor first;
- you have a disease (such as Human Immunodeficiency Virus (HIV) or Acquired Immune Deficiency Syndrome (AIDS)) or are taking any medication that may weaken the immune system. Whether or not you receive the vaccination will depend on the level of your defenses;
- you are pregnant. Additionally, pregnancy should be avoided for 1 month after vaccination.
Warnings and precautions
Consult your doctor or pharmacist before you are vaccinated with Priorix if:
- you have central nervous system disorders, a history of seizures accompanied by high fever or a family history of seizures. In case of high fever after vaccination, consult your doctor immediately;
- you have ever had a severe allergic reaction to egg proteins;
- you have had an adverse reaction after vaccination against measles, mumps or rubella that involved easy bruising or bleeding for longer than usual (see section 4);
- you have a weakened immune system (e.g., HIV infection). You should be closely monitored as the response to vaccination may not be sufficient to ensure protection against the disease (see section 2 "Priorix must not be administered if").
Before or after any injection, fainting (especially in adolescents) may occur, so you should inform your doctor or nurse if you have fainted after receiving an injection in the past.
If you are vaccinated within 72 hours of contact with someone who has measles, Priorix will provide some protection against the disease.
Children under 12 months
It is possible that children vaccinated during their first year of life may not be fully protected. Your doctor will advise you if additional doses of the vaccine are required.
As with all vaccines, it is possible that Priorix may not fully protect all vaccinated individuals.
Use of Priorix with other medicines
Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines (or other vaccines).
Priorix can be administered to you at the same time as other vaccines such as diphtheria, tetanus, pertussis, Haemophilus influenzaetype b, oral or inactivated polio, hepatitis A, hepatitis B, varicella, meningococcal group B vaccines, as well as meningococcal group C, meningococcal groups A, C, W-135, Y and pneumococcal conjugate vaccine. Consult your doctor or nurse for more information.
A different injection site should be used for each vaccine.
If they are not administered at the same time, an interval of at least one month is recommended between the administration of Priorix and other live attenuated vaccines.
Your doctor may delay vaccination for at least 3 months if you have received blood transfusions or human antibodies (immunoglobulins).
If a tuberculin test is to be performed, it should be done before, at the same time as, or 6 weeks after vaccination with Priorix.
Pregnancy, breastfeeding and fertility
Priorix must not be administered to pregnant women.
If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before vaccination. It is also important that you do not become pregnant for 1 month after vaccination. During this time, you should use an effective method of contraception to prevent pregnancy.
In the event of unintended vaccination of pregnant women with Priorix, this should not be a reason to terminate the pregnancy.
Priorix contains sorbitol, para-aminobenzoic acid, phenylalanine, sodium and potassium
This vaccine contains 9 mg of sorbitol per dose.
Priorix contains para-aminobenzoic acid. It may cause allergic reactions (possibly delayed) and, exceptionally, bronchospasm.
This vaccine contains 334 micrograms of phenylalanine per dose. Phenylalanine may be harmful in cases of phenylketonuria (PKU), a rare genetic disorder in which phenylalanine accumulates because the body is unable to eliminate it properly.
This vaccine contains less than 23 mg of sodium (1 mmol) per dose; it is essentially "sodium-free".
This vaccine contains less than 39 mg (1 mmol) of potassium per dose, so it is considered essentially "potassium-free".
3. How Priorix is administered
Priorix is administered under the skin or into the muscle, either in the upper arm or on the outer thigh.
Priorix is intended for children from 9 months, adolescents and adults.
Your doctor will determine the timing and number of injections suitable for you based on official recommendations.
The vaccine should never be administered into a vein.

-----------------------------------------------------------------------------------------------------------------------------
This information is intended only for healthcare professionals:
As with all injectable vaccines, appropriate medical treatment and supervision should be available to deal with the rare possibility of anaphylactic reactions following administration of the vaccine.
Since alcohol and other disinfectants can inactivate the live attenuated viruses of the vaccine, they should be allowed to evaporate from the skin before administration.
Priorix must not be administered intravascularly under any circumstances.
In the absence of compatibility studies, this medicinal product must not be mixed with other medicinal products.
Before reconstitution or administration, the solvent and the reconstituted vaccine should be inspected visually for any foreign particles and/or changes in physical appearance. If any are observed, the solvent or the reconstituted vaccine should not be used.
The vaccine should be reconstituted by adding the entire contents of the pre-filled syringe to the vial containing the powder.
To learn how to insert the needle into the syringe, read the instructions provided with images 1 and 2 carefully. However, the syringe provided with Priorix may be slightly different (without screw thread) from the syringe in the image. In this case, the needle should be inserted without screwing.
Always hold the syringe by the body, not by the plunger or the Luer adapter (LA), and keep the needle in line with the syringe (as shown in image 2). Otherwise, the LA could become deformed and cause leaks.
If the LA comes off during syringe assembly, use a new dose of the vaccine (new syringe and vial).
- Unscrew the syringe protector by turning it counterclockwise (as shown in image 1).
Whether or not the LA turns, please follow the next steps:
- Insert the needle into the syringe by gently fitting the cone of the needle into the LA and turning a quarter turn clockwise until it clicks (as shown in image 2).
- Remove the needle protector (it may be difficult).
- Add the solvent to the powder. Shake the mixture well until the powder is completely dissolved.
Due to minor variations in its pH, the color of the reconstituted vaccine may vary from light orange to pink without affecting the potency of the vaccine.
- Withdraw the entire contents of the vial.
- A new needle should be used to administer the vaccine. Unscrew the needle from the syringe and insert the needle for injection, repeating the previous step 2.
The vaccine should be administered immediately after reconstitution. If this is not possible, it should be stored between 2°C and 8°C and used before 8 hours after reconstitution.
Disposal of unused medicinal products and all materials that have come into contact with them should be done in accordance with local regulations.
