4. Clinical particulars
4.1 Therapeutic indications

NeisVac-C is indicated for active immunisation in children from 2 months of age, adolescents and adults, for the prevention of invasive disease caused by Neisseria meningitidis serogroup C.

The use of NeisVac-C should be determined on the basis of official recommendations.

4.2 Posology and method of administration

There are no data on the use of different meningococcal group C conjugate vaccines within the primary series or for boosting. Whenever possible, the same vaccine should be used throughout.

Posology

Primary immunisation

Infants from 2 months up to 4 months of age:

Two doses, each of 0.5 ml, should be given with an interval of at least two months

Infants from 4 months of age, older children, adolescents and adults:

One dose of 0.5 ml

Booster doses

After completion of the primary immunization course in infants aged 2 months up to 12 months of age a booster dose should be given at approximately 12-13 months of age with at least an interval of 6 months after the last NeisVac-C vaccination.

The need for booster doses in subjects aged 12 months or more when first immunised has not yet been established (see section 5.1).

Method of administration

NeisVac-C is for intramuscular injection, preferably in the anterolateral thigh region in infants and the deltoid region in older children, adolescents, and adults. In children 12 to 24 months of age, the vaccine may be administered in the deltoid or the anterolateral thigh.

Precautions to be taken before handling or administering the medicinal product

The vaccine must not be administered subcutaneously or intravenously (see section 4.4).

NeisVac-C must not be mixed with other vaccines in the same syringe. Separate injection sites should be used if more than one vaccine is being administered (see section 4.5).

4.3 Contraindications

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1, including tetanus toxoid.

As with any vaccine, administration of NeisVac-C should be postponed for subjects suffering from an acute severe febrile illness.

4.4 Special warnings and precautions for use

Adequate medical treatment and provisions should be available for immediate use in the rare event of an anaphylactic reaction. For this reason the subject should remain under supervision for the appropriate length of time after vaccination.

NeisVac-C SHOULD UNDER NO CIRCUMSTANCES BE INJECTED INTRAVENOUSLY OR SUBCUTANEOUSLY.

Because of the risk of bleeding or hematoma at the injection site, benefits and risks should be carefully weighed when considering use of the vaccine in individuals with any coagulation disorder (e.g., thrombocytopenia) or concomitant anticoagulant therapy.

The potential risk of apnoea and the need for respiratory monitoring for 48-72 h should be considered when administering the primary immunisation series to very premature infants (born ≤ 28 weeks of gestation) and particularly for those with a previous history of respiratory immaturity.

As the benefit of vaccination is high in this group of infants, vaccination should not be withheld or delayed.

This medicinal product contains less than 1 mmol sodium (23 milligrams) per dose, i.e. essentially “sodium-free”.

No data on the applicability of the vaccine to outbreak control are as yet available.

The benefit-risk assessment of vaccination with NeisVac-C depends on the incidence of N. meningitidis serogroup C infection in a given population before the institution of a widespread immunisation programme.

Vaccination should be postponed in subjects with acute clinical conditions (with or without fever) that could be aggravated by adverse reactions to the vaccine or could impair the interpretation of possible adverse reactions to the vaccine.

In subjects deficient in producing antibody (e.g. due to genetic defect or immunosuppressive therapy) this vaccine may not induce protective antibody levels following vaccination. Hence, vaccination may not result in an appropriate protective antibody response in all individuals.

Persons with familial complement deficiencies (for example, C5 or C3 deficiencies) and persons receiving treatments that inhibit terminal complement activation (for example, eculizumab) are at increased risk for invasive disease caused by Neisseria meningitidis serogroup C, even if they develop antibodies following vaccination with NeisVac-C.

It would be anticipated that individuals with complement deficiencies and individuals with functional or anatomical asplenia would mount an immune response to meningococcal C conjugate vaccines; however, the degree of protection that would be afforded is unknown.

Although symptoms of meningism such as neck pain/stiffness or photophobia have been reported there is no evidence that meningococcal group C conjugate vaccines cause meningococcal C meningitis. Clinical alertness to the possibility of co-incidental meningitis should therefore be maintained.

This vaccine does not substitute for routine tetanus immunisation.

NeisVac-C will only confer protection against group C of Neisseria meningitidis and may not completely prevent meningococcal group C disease. It will not protect against other groups of Neisseria meningitidis or other organisms that cause meningitis or septicaemia. In the event of petechiae and/or purpura following vaccination (see section 4.8), the aetiology should be thoroughly investigated. Both infective and non-infective causes should be considered.

There are no data on the use of NeisVac-C in adults aged 65 years or more (see section 5.1).

4.5 Interaction with other medicinal products and other forms of interaction

NeisVac-C must not be mixed with other vaccines in the same syringe. Separate injection sites should be used if more than one vaccine is being administered.

Administration of NeisVac-C at the same time (but into a different injection site) as vaccines containing the following antigens did not have a potentially clinically significant effect on immune responses to these antigens in clinical trials:

- diphtheria and tetanus toxoids

- whole cell pertussis vaccine (wP)

- acellular pertussis vaccine (aP)

- Haemophilus influenzae conjugate vaccine (Hib)

- inactivated polio vaccine (IPV)

- measles, mumps and rubella vaccine (MMR)

- pneumococcal conjugate vaccines (7-, 10-, and 13-valent)

Minor variations in geometric mean antibody levels were sometimes observed between concomitant and separate administrations but the clinical significance, if any, of these observations is not established.

Concomitant administration of NeisVac-C (2 dose infant schedule) and DTaP-IPV-HBV-Hib in a 3-dose primary series in infants did not indicate any clinically relevant interference with responses to any of the antigens in the hexavalent vaccine.

In various studies with different vaccines, concomitant administration of meningococcal serogroup C conjugates with combinations containing acellular pertussis components (with or without inactivated polio viruses, hepatitis B surface antigen or Hib conjugates) has been shown to result in lower SBA GMTs compared to separate administrations or to co-administration with whole cell pertussis vaccines. The proportions reaching SBA titres of at least 1:8 or 1:128 are not affected. At present, the potential implications of these observations for the duration of protection are not known.

The antibody response rate to NeisVac-C, when given one month after tetanus toxoid containing vaccine, was 95.7% as compared to 100% when vaccines were administered concurrently.

Co-administration of an oral, live rotavirus vaccine (RotaTeq vaccine) with NeisVacC at 3 and 5 months of age (and usually at the same time as DTaP-IPV-Hib vaccine), followed by a third dose of the rotavirus vaccine at approximately 6 months of age, demonstrated that the immune responses to both vaccines were unaffected. Co-administration resulted in an acceptable safety profile.

4.6 Fertility, pregnancy and lactation

Pregnancy

There are no adequate data from the use of this vaccine in pregnant women. Animal studies are insufficient with respect to the effects on pregnancy and embryonal/foetal development, parturition, and postnatal development. The potential risk for humans is unknown. Nevertheless, considering the severity of meningococcal C disease, pregnancy should not preclude vaccination when the risk of exposure is clearly defined.

Breast-feeding

There are no adequate data from the use of this vaccine in lactating women. The risk-benefit relationship should be examined before making the decision as to whether to immunise during lactation.

Fertility

The effects of NEISVAC-C on fertility have not been established.

4.7 Effects on ability to drive and use machines

The vaccine is unlikely to impair the ability to drive or operate machinery.

4.8 Undesirable effects

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose

Overdosing with the vaccine is highly unlikely, because it is administered as a single dose syringe by a health care provider.

Multiple doses: in a clinical study in infants, 40 subjects received three doses of NeisVac-C at 2, 3, and 4 months and a fourth dose at 12-14 months of age. All four vaccine doses were well tolerated with no serious vaccine related adverse events.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic Group: Meningococcal vaccine

Immunogenicity in Toddlers

In a study investigating the immune response of a single dose of NeisVac-C 100% of the toddlers presented with an rSBA titre of at least 1:8.

Immunogenicity in children aged 3.5-6 years

In a study investigating the immune response of a single dose of NeisVac-C 98.6% of the children presented with an rSBA titre of at least 1:8.

Immunogenicity in adolescents aged 13-17 years and adults

In a study investigating the immune response of a single dose of NeisVac-C 100% of adolescents presented with an rSBA titre of at least 1:8.

In a clinical study in adults aged 18 to 64 years, 95.6% not previously vaccinated and 97.1% with a history of previous vaccination with a plain polysaccharide Men C vaccine had SBA titres of at least 1:8 after a single dose of NeisVac-C.

Post-marketing surveillance following an immunisation campaign in the UK

Estimates of vaccine effectiveness from the UK's routine immunisation programme (using various quantities of three meningococcal group C conjugate vaccines) covering the period from introduction at the end of 1999 to March 2004 demonstrated the need for a booster dose after completion of the primary series (three doses administered at 2, 3, and 4 months). Within one year of completion of the primary series, vaccine effectiveness in the infant cohort was estimated at 93% (95% confidence intervals 67, 99). However, more than one year after completion of the primary series, there was clear evidence of waning protection.

Up to 2007 the overall estimates of effectiveness in age cohorts from 1-18 years that received a single dose of meningococcal group C conjugate vaccine during the initial catch-up vaccination programme in the UK range between 83 and 100%. The data show no significant fall in effectiveness within these age cohorts when comparing time periods less than a year or one year or more since immunisation.

Post-marketing surveillance following immunisation in the Netherlands

In September 2002, the Netherlands implemented routine meningococcal group C vaccination for toddlers at 14 months of age. In addition, between June and November 2002, a catch-up campaign from 1-18 years of age was carried out. The catch-up campaign in the Netherlands covered nearly 3 million subjects (94% coverage). Disease surveillance in the Netherlands where NeisVac-C has been used exclusively in the vaccination programmes revealed that the incidence of meningococcal C disease has decreased sharply.
