PRIORIX Product Information
PRIORIX® PRODUCT INFORMATION
DESCRIPTION
PRIORIX is a live virus vaccine for immunisation against measles, mumps and rubella. PRIORIX is a sterile lyophilised mixed preparation containing the attenuated Schwarz measles virus strain, the RIT 4385 strain of mumps virus (derived from the Jeryl Lynn strain) and the Wistar RA 27/3 rubella virus strain. Each virus strain is separately obtained by propagation in either chick embryo tissue cultures (mumps and measles) or MRC5 human diploid cells (rubella). PRIORIX is presented as a white to slightly pink pellet for reconstitution with sterile Water for Each 0.5mL dose of the reconstituted vaccine contains not less than 103.0 CCID50 (cell culture infectious dose 50%) of the Schwarz measles, not less than 103.7 CCID50 of the RIT 4385 mumps and not less than 103.0 CCID50 of the Wistar RA 27/3 rubella virus strains. The three virus strains are mixed prior to lyophilisation. The lyophilised vaccine also contains lactose, neomycin sulphate, amino acids and sorbitol and mannitol as stabilisers. The manufacture of this product includes exposure to bovine derived materials. No evidence exists that any case of vCJD (considered to be the human form of bovine spongiform encephalopathy) has resulted from the administration of any vaccine product. PRIORIX meets the World Health Organisation requirements for manufacture of biological substances and for measles, mumps and rubella vaccines and combined vaccines (live). CLINICAL PHARMACOLOGY
PRIORIX induces antibodies against all vaccine components. Clinical Trials
Seroconversion has been shown to equate with protection against each of the measles, mumps Primary Immunisation:
In clinical studies, PRIORIX has been demonstrated to be highly immunogenic. PRIORIX Product Information
In previously seronegative vaccinees, antibodies were detected in 98.0%, 96.1% and 99.3% of subjects against measles, mumps and rubella respectively. In a pooled analysis of comparative studies of over 1400 children, antibodies against measles, mumps and rubella were detected in 98.7%, 95.5% and 99.5% of previously seronegative subjects (n=1094) who received PRIORIX. Antibodies against measles, mumps and rubella were detected in 96.9%, 96.9% and 99.5% of subjects (n=388) respectively, who had received a commercially Similar seroconversion rates were seen in subjects who received PRIORIX by the intramuscular Seroconversion rates in a limited number of subjects (n=60) aged 9-11 months were also measured. 100% of these subjects developed antibodies against mumps and rubella. 96.6% of the subjects developed anti-measles antibodies. Antibody levels of participants in the pooled studies have been monitored for up to 12 months following vaccination. All subjects remained seropositive for anti-measles and anti-rubella antibodies. Anti-mumps antibodies were detected in 88.4% of subjects. A similar result was observed with a commercially available MMR vaccine. In a more recent study comparing the current formulation of PRIORIX (albumin-free) with the previous formulation containing albumin, antibodies against measles, mumps and rubella were detected in 98.4, 94.8 and 100% of previously seronegative subjects (n=191) who received the current formulation. Antibodies against measles, mumps and rubella were detected in 99.5, 94.7 and 100% of subjects (n=190) respectively, who had received the formulation used in the earlier studies containing albumin. There were no significant differences in immunogenicity between the current formulation of PRIORIX (albumin-free) and the formulation containing albumin used in the Booster Immunisation:
A booster dose of PRIORIX was administered to children aged 4 - 6 years or 11-12 years, who had been primed with a different MMR vaccine. All subjects aged 4-6 years who were seronegative at the time of booster, subsequently seroconverted. In subjects aged 11 -12 years who were seronegative at the time of booster, seroconversion rates of 85.7%, 93.5% and 100% were observed for measles, mumps and rubella respectively. PRIORIX Product Information
INDICATIONS
PRIORIX is indicated for active immunisation against measles, mumps and rubella. The Australian NH&MRC Immunisation Handbook recommendations for MMR vaccination are as MMR vaccine is recommended for all children at 12 months of age and again at 4-6 years of age unless there is a genuine contraindication. In populations with a high incidence of early measles, vaccination at 9 months of age is recommended. Because of the risk to Aboriginal children, the Northern Territory health authority has adopted a practice of administering the first dose of MMR vaccine to Aboriginal children at the age of 9 months. This conforms with WHO recommendations for such populations. The second Unimmunised children in the following groups are at particular risk from severe measles infection: • children with chronic conditions such as cystic fibrosis, congenital heart or kidney disease, failure to thrive, Down Syndrome, • children from the age of 1 year upwards in child care centres, family day care and playgroups, • children living in institutions, and • Aboriginal and Torres Strait Islander children. HIV-positive individuals may be given measles, mumps, rubella combined vaccines in the absence CONTRAINDICATIONS
It is contraindicated to administer PRIORIX to pregnant women (See Use in Pregnancy). If vaccination of postpubertal women occurs, pregnancy should be avoided for three months. PRIORIX should not be administered to subjects with known hypersensitivity to any components of the vaccine. Vaccination is contraindicated in children who are allergic to neomycin, although a history of contact dermatitis to neomycin is not a contraindication. As with other vaccines, the administration of PRIORIX should be postponed in subjects suffering from acute severe febrile illness. The presence of a minor infection, however, is not a PRIORIX Product Information
PRIORIX should not be given to subjects with impaired immune responses. These include patients with primary or secondary immunodeficiencies¸ those with untreated malignant disease and those receiving immunosuppressive or X-ray therapy or high dose steroids (equivalent to However, measles, mumps, rubella combined vaccines can be given to asymptomatic HIV-infected persons without adverse consequence to their illness, and may be considered for those who are PRECAUTIONS
PRIORIX should under no circumstances be administered intravenously.
As with all injectable vaccines, appropriate medical treatment (i.e. adrenaline) and supervision should always be readily available in case of anaphylactic reactions following the administration of Alcohol and other disinfecting agents must be allowed to evaporate from the skin before injection of the vaccine as they can inactivate the attenuated viruses in the vaccine. Infants below 12 months of age may not respond sufficiently to the measles component of the vaccine due to the possible persistence of maternal measles antibodies. This should not preclude the use of the vaccine in younger infants (< 12 months) as vaccination may be indicated in certain situation such as high risk areas (see Indications). In these circumstances revaccination at or after Limited protection against measles may be obtained by vaccination up to 72 hours after exposure to natural measles. If the vaccination status of the child is in doubt, the vaccine should be given as there are no ill effects of vaccinating individuals who are already immune. The antibody response to the rubella and mumps components is too slow for effective post-exposure prophylaxis. Transmission of measles and mumps virus from vaccinees to susceptible contacts has never been documented. Pharyngeal excretion of the rubella virus is known to occur about 7 to 28 days after vaccination with peak excretion around the 11th day. However there is no evidence of transmission of this excreted virus to susceptible contacts. PRIORIX should be given with caution to persons with a history or family history of allergic disease or those with a history or family history of convulsions. PRIORIX Product Information
The measles and mumps components of the vaccine are produced in chick embryo cell culture and may therefore contain traces of egg protein. Persons with a history of anaphylactic, anaphylactoid, or other immediate reactions (e.g., hives, swelling of the mouth and throat, difficulty breathing, hypotension, or shock) subsequent to egg ingestion should not be vaccinated with It appears that persons are not at increased risk if they have egg allergies that are not anaphylactic or anaphylactoid in nature. Such persons may be vaccinated in the usual manner. There is no evidence to indicate that persons with allergies to chickens or feathers are at increased risk of As for any vaccine, immunisation with measles, mumps, rubella vaccine may not result in seroconversion in 100% of susceptible persons given the vaccine. Use in Pregnancy (Category B2):
It is contraindicated to administer PRIORIX to pregnant women. Pregnancy should be avoided for three months after vaccination (see Contraindications). The Australian Medicines in Pregnancy handbook (3rd edition) states that: Currently available live virus vaccines have not caused teratogenic effects in humans. Caution needs to be exercised as live virus vaccines have been shown to cross the placenta and infect the foetus. Some live virus vaccines have caused birth defects in animals. (The NH&MRC publication “Immunisation Procedures” should be consulted for more comprehensive information.) Women of child bearing age should be tested for rubella antibodies prior to pregnancy. All seronegative women, provided they are not pregnant, should be offered rubella vaccine. Those administering the vaccine should be careful to instruct women to whom it is given that they should not become pregnant for at least two full menstrual cycles because rubella vaccine can cause foetal infection. However, to date, there have not been any rubella-like birth defects in the live born infants (about 400) of seronegative mothers vaccinated during or just before pregnancy. Based on this experience, the rubella vaccine cannot be considered teratogenic during pregnancy and need not be the reason to recommend termination of pregnancy. The final decision must be Use in Lactation:
There is little human data regarding use in breastfeeding women. Persons can be vaccinated PRIORIX Product Information
Interactions
Although data on concomitant administration of PRIORIX and other vaccines have not been obtained, it is accepted that measles, mumps and rubella combined vaccines may be given at the same time as oral polio vaccine (OPV), inactivated polio vaccine (IPV), combined diphtheria, tetanus and pertussis vaccines (acellular or whole-cell), hepatitis B vaccines and Haemophilus influenzae type b vaccines (Hib), as long as separate sites and separate syringes are used. If PRIORIX cannot be given at the same time as another live attenuated vaccine, an interval of at least 1 month should be left between the two vaccinations. If tuberculin (Mantoux) testing is needed, it should be carried out before, or simultaneously with measles, mumps and rubella vaccination. It has been reported that live measles (and possibly mumps) vaccine may cause a temporary depression of tuberculin skin sensitivity which could last 4 to 6 weeks. Tuberculin testing is therefore unreliable (false negative) for 4 to 6 weeks after administration of measles, mumps, rubella vaccine. In subjects who have received human gammaglobulins or blood transfusions, vaccination should be delayed for at least 3 months because of the possibility of vaccine failure due to passively acquired measles, mumps and rubella antibodies. PRIORIX should not be mixed with other vaccines in the same syringe. PRIORIX can be used as a booster dose in subjects who have previously been vaccinated with PRIORIX or another measles, mumps and rubella combined vaccine. ADVERSE REACTIONS

DOSAGE AND ADMINISTRATION
All parenteral drug and vaccine products should be inspected visually for any particulate matter and/or variation of physical aspects prior to administration. The vaccine must be reconstituted by adding 0.5mL of sterile water diluent to the vial containing the pellet of lyophilised vaccine. After the addition of the diluent to the pellet, the mixture should be well shaken until the pellet is completely dissolved in the diluent. The vaccine should be injected as soon as possible after reconstitution. The reconstituted vaccine can be stored between +2 and +8°C, for up to 8 hrs before use. A reconstituted dose of 0.5mL is recommended for children and adults. Two doses are usually given. The first dose is usually given at 12 months of age, followed by a booster dose at 4 - 6 years of age (see Indications). A single dose may be given to adults who do not have immunity. Administration
PRIORIX is administered by subcutaneous or intramuscular injection. THE VACCINE SHOULD The NH&MRC recommends that MMR vaccines should be administered into the anterolateral thigh of children under 12 months of age. The deltoid region is the preferred site of vaccination in older The vaccine should be stored between +2°C and +8°C in a refrigerator. The expiry date of the vaccine is indicated on the label and packaging. The shelf life of PRIORIX is 24 months from the date of manufacture when stored at a temperature between +2°C and +8°C.
