| Frequencies are reported as:Very common: | 10%
| Common: | 1% and < 10%
| Uncommon: | 0.1% and < 1%
| Rare: | 0.01% and < 0.1%
| Very rare: | < 0.01% | In controlled clinical studies in children aged from 9 months to 2 years, signs and symptoms were actively monitored during a 42-day follow-up period. Parents/guardians of the vaccinees were also requested to report any adverse events during the study period. The safety profile presented below is based on a total of approximately 12,000 subjects administered Priorix in clinical trialsInfections and infestations: Uncommon: otitis mediaCommon: upper respiratory tract infectionBlood and lymphatic system disorders: Uncommon: lymphadenopathyImmune system disorders: Rare: allergic reactionsMetabolism and nutrition disorders: Uncommon: anorexiaPsychiatric disorders: Uncommon: nervousness, abnormal crying, insomniaNervous system disorders: Rare: febrile convulsionsEye disorders: Uncommon: conjunctivitisRespiratory, thoracic and mediastinal disorders: Uncommon: bronchitis, coughGastrointestinal disorders: Uncommon: parotid gland enlargement, diarrhoea, vomitingSkin and subcutaneous tissue disorders: Common: rashGeneral disorders and administration site conditions: Very common: redness at the injection site, fever 38°C (rectal) or 37.5°C (axillary/oral)Common: pain and swelling at the injection site, fever >39.5°C (rectal) or >39°C (axillary/oral)In general, the frequency category for adverse reactions was similar for the first and second vaccine doses. The exception to this was pain at the injection site which was Common after the first vaccine dose and Very common after the second vaccine dose.During post-marketing surveillance, the following reactions have been reported in temporal association with Priorix vaccination:Infections and infestations: MeningitisBlood and lymphatic system disorders: Thrombocytopenia, thrombocytopenic purpuraImmune system disorders Anaphylactic reactionsNervous system disorders: Transverse myelitis, Guillain Barré syndrome, peripheral neuritis, encephalitis*Skin and subcutaneous tissue disorders: Erythema multiformeMusculoskeletal and connective tissue disorders: Arthralgia, arthritisGeneral disorders and administration site conditions:Kawasaki syndromeAs in natural rubella infection, arthralgia, or in isolated cases, chronic arthritis as well as myalgia, exanthema and swollen lymph nodes may occur two to four weeks after administration of live rubella vaccines. The incidence of joint reactions increases with the age of the vaccinee. Cases of exudative arthritis are extremely rare.In rare cases a mumps-like condition with an abbreviated incubation period cannot be ruled out. In isolated cases, a transient, painful swelling of the testicles had been reported after combined mumps, measles, rubella vaccination.Accidental intravascular administration may give rise to severe reactions or even shock. Immediate measures depend on the severity of the reaction.In comparative studies with other measles, mumps and rubella vaccines, the incidences of local pain, redness and swelling reported with Priorix were low, while the incidences of other adverse reactions were similar.* Encephalitis has been reported with a frequency below 1 per 10 million doses. The risk of encephalitis following administration of the vaccine is far below the risk of encephalitis caused by natural diseases (measles: 1 in 1000 to 2000 cases; rubella: approximately 1 in 6000 cases).In rare cases a measles-like syndrome has been reported following vaccination with Priorix. | |
