| The following descriptions of frequency have been defined: Very common ( 10%); common ( 1% and <10%); uncommon ( 0.1% and <1%); rare ( 0.01% and <0.1%); very rare (<0.01%).Adverse Reactions from clinical trials Adverse reactions reported across all age groups are provided below. Adverse reactions were collected on the day of vaccination and each day following for at least 3 and up to 6 days. The majority of reactions were self-limiting and resolved within the follow-up period.In all age groups injection site reactions (including redness, swelling and tenderness/pain) were very common (ranging from 1 in 3 older children to 1 in 10 pre-school children). However, these were not usually clinically significant. Redness or swelling of at least 3cm and tenderness interfering with movement for more than 48 hours was infrequent where studied.Fever of at least 38.0°C is common (ranging from 1 in 20 in infants and toddlers to 1 in 10 in pre-school children), but does not usually exceed 39.1°C, particularly in older age groups.In infants and toddlers symptoms including crying and vomiting (toddlers) were common after vaccination. Irritability, drowsiness, impaired sleeping, anorexia, diarrhoea and vomiting (infants) were very common after vaccination. There was no evidence that these were related to Menjugate Kit rather than concomitant vaccines, particularly DTP.Very commonly reported adverse events include myalgia and arthralgia in adults. Drowsiness was commonly reported in younger children. Headache was very common in secondary school children and common in primary school children.Adverse reactions reported across all age groups | General disorders and administration site conditions | | Very common

Adverse Reactions from Post Marketing Surveillance (for all age groups) The most commonly reported suspected reactions in post marketing surveillance include dizziness, pyrexia, headache, nausea, vomiting and faints.The frequencies given below are based on spontaneous reporting rates, for this and other Meningococcal group C conjugate vaccines and have been calculated using the number of reports received as the numerator and the total number of doses distributed as the denominator.| Nervous system disorders | | | Very rare
| Dizziness, convulsions including febrile convulsions, faints, hypoaesthesia and paraesthesia, hypotonia
| There have been very rare reports of seizures following Menjugate Kit vaccination; individuals have usually rapidly recovered. Some of the reported seizures may have been faints. The reporting rate of seizures was below the background rate of epilepsy in children. In infants seizures were usually associated with fever and were likely to be febrile convulsions.There have been very rare reports of visual disturbances and photophobia following vaccination with Meningococcal group C conjugate vaccines, usually in conjunction with other neurological symptoms like headache and dizziness.| Respiratory, thoracic and mediastinal disorders | Apnoea in very premature infants ( 28 weeks of gestation) (see section 4.4)

| Gastrointestinal disorders | | | Very rare
| Nausea, vomiting and diarrhoea
|
| Skin and subcutaneous tissue disorders | | Very rare

| Immune system disorders | | | Very rare
| Lymphadenopathy, anaphylaxis, hypersensitivity reactions including bronchospasm, facial oedema and angioedema. | Relapse of nephrotic syndrome has been reported in association with Meningococcal group C conjugate vaccines. | |
