What it is and what it is used for

for

Bexsero is a Meningococcal group B Vaccine. Bexsero contains four different components from the surface of the bacteria Neisseria meningitidis group B. Bexsero is given to individuals from 2 months of age and older to help protect against disease caused by the Neisseria meningitidis group B bacteria. These bacteria can cause serious, and sometimes life-threatening, infections such as meningitis (inflammation of the covering of the brain and spinal cord) and sepsis (blood poisoning). The vaccine works by specifically stimulating the body's natural defense system of the vaccinated person. This results in protection against the disease.

What you need to know before you or your child receive BEXSERO

Do NOT use Bexsero –

if you or your child are allergic to the active substances or any of the other ingredients of this vaccine (listed in section 6).

Warnings and precautions Talk to your doctor or nurse before you or your child receive Bexsero: if you or your child have a severe infection with a high temperature. If this is the case, then vaccination will be postponed. The presence of a minor infection, such as a cold, should not require postponement of the vaccination, but talk to your doctor or nurse first. if you or your child have haemophilia or any other problem that may stop your blood from clotting properly, such as treatment with blood thinners (anticoagulants). Talk to your doctor or nurse first.

if you or your child receive treatment that blocks the part of the immune system known as complement activation, such as eculizumab. Even if you or your child have been vaccinated with Bexsero you or your child remain at increased risk of disease caused by the Neisseria meningitidis group B bacteria. if your child was born prematurely (before or at 28 weeks of pregnancy), particularly if they had breathing difficulties. Stopping breathing or irregular breathing for a short time may be more common in the first three days following vaccination in these babies and they may need special monitoring. if you or your child have an allergy to the antibiotic kanamycin. If present, the kanamycin level in the vaccine is low. If you or your child may have an allergy to kanamycin, talk to your doctor or nurse first.

Fainting, feeling faint or other stress-related reactions can occur as a response to any needle injection. Tell your doctor or nurse if you have experienced this kind of reaction previously. There are no data on the use of Bexsero in adults above 50 years of age. There are limited data on the use of Bexsero in patients with chronic medical conditions or with weakened immunity. If you or your child have weakened immunity (for example, due to the use of immunosuppressive medications, or HIV infection, or hereditary defects of the body's natural defence system), it is possible that the effectiveness of Bexsero is reduced. As with any vaccine, Bexsero may not fully protect all of those who are vaccinated. Other medicines and Bexsero Tell your doctor or nurse if you or your child are taking, have recently taken, or might take any other medicines, or have recently received any other vaccine. Bexsero can be given at the same time as any of the following vaccine components: diphtheria, tetanus, whooping cough (pertussis), Haemophilus influenzae type b, polio, hepatitis B, pneumococcus, measles, mumps, rubella, chickenpox, and meningococcus A, C, W, Y. Talk to your doctor or nurse for further information. When given at the same time with other vaccines Bexsero must be given at separate injection sites. Your doctor or nurse may ask you to give your child medicines that lower fever at the time and after Bexsero has been given. This will help to reduce some of the side effects of Bexsero. Pregnancy and breast-feeding If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before Bexsero is given. Your doctor may still recommend that you receive Bexsero if you are at risk of exposure to meningococcal infection. Driving and using machines Bexsero has no or negligible influence on the ability to drive and use machines. However, some of the effects mentioned under section 4 "Possible side effects" may temporarily affect the ability to drive or use machines. Bexsero contains sodium chloride This medicinal product contains less than 1 mmol sodium (23 mg) per dose, i.e. essentially 'sodium-free'.

4.1. Therapeutic indications

Bexsero is indicated for active immunisation of individuals from 2 months of age and older against invasive meningococcal disease caused by Neisseria meningitidis group B. The impact of invasive disease in different age groups as well as the variability of antigen epidemiology for group B strains in different geographical areas should be considered when vaccinating. See section 5.1 for information on protection against specific group B strains. The use of this vaccine should be in accordance with official recommendations.

* There are no data in adults above 50 years of age.

Method of administration

The vaccine is given by deep intramuscular injection, preferably in the anterolateral aspect of the thigh in infants or in the deltoid muscle region of the upper arm in older subjects.

Separate injection sites must be used if more than one vaccine is administered at the same time.

The vaccine must not be injected intravenously, subcutaneously or intradermally and must not be mixed with other vaccines in the same syringe.

For instructions on the handling of the vaccine before administration, see section 6.6.

4.3. Contraindications

Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.

4.4. Special warnings and precautions for use

Traceability

In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

As with other vaccines, administration of Bexsero should be postponed in subjects suffering from an acute severe febrile illness. However, the presence of a minor infection, such as cold, should not result in the deferral of vaccination.

Do not inject intravascularly.

As with all injectable vaccines, appropriate medical treatment and supervision should always be readily available in case of an anaphylactic event following the administration of the vaccine.

Anxiety-related reactions, including vasovagal reactions (syncope), hyperventilation or stress-related reactions may occur in association with vaccination as a psychogenic response to the needle injection (see section 4.8). It is important that procedures are in place to avoid injury from fainting.

This vaccine should not be given to individuals with thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injection, unless the potential benefit clearly outweighs the risk of administration.

As with any vaccine, vaccination with Bexsero may not protect all vaccine recipients.

Bexsero is not expected to provide protection against all circulating meningococcal group B strains (see section 5.1).

As with many vaccines, healthcare professionals should be aware that a temperature elevation may occur following vaccination of infants and children (less than 2 years of age). Prophylactic administration of antipyretics at the time of and closely after vaccination can reduce the incidence and intensity of post-vaccination febrile reactions. Antipyretic medication should be initiated according to local guidelines in infants and children (less than 2 years of age).

Individuals with impaired immune responsiveness, whether due to the use of immunosuppressive therapy, a genetic disorder, or other causes, may have reduced antibody response to active immunisation.

Immunogenicity data are available in individuals with complement deficiencies, asplenia, or splenic dysfunctions (see section 5.1).

Individuals with familial complement deficiencies (for example, C3 or C5 deficiencies) and individuals receiving treatments that inhibit terminal complement activation (for example, eculizumab) are at increased risk for invasive disease caused by Neisseria meningitidis group B, even if they develop antibodies following vaccination with Bexsero.

There are no data on the use of Bexsero in subjects above 50 years of age and limited data in patients with chronic medical conditions.

The potential risk of apnoea and the need for respiratory monitoring for 48-72 hours 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.

Kanamycin is used in early manufacturing process and is removed during the later stages of manufacture. If present, kanamycin levels in the final vaccine are less than 0.01 micrograms per dose.

The safe use of Bexsero in kanamycin-sensitive individuals has not been established.

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

4.5. Interaction with other medicinal products and other forms of interaction

Use with other vaccines

Bexsero can be given concomitantly with any of the following vaccine antigens, either as monovalent or as combination vaccines: diphtheria, tetanus, acellular pertussis, Haemophilus influenzae type b, inactivated poliomyelitis, hepatitis B, heptavalent pneumococcal conjugate, measles, mumps, rubella, varicella, and meningococcal groups A, C, W, Y conjugate.

Clinical studies demonstrated that the immune responses of the co-administered routine vaccines were unaffected by concomitant administration of Bexsero, based on non-inferior antibody response rates to the routine vaccines given alone. Inconsistent results were seen across studies for responses to inactivated poliovirus type 2 and pneumococcal conjugate serotype 6B and lower antibody titers to the pertussis pertactin antigen were also noted, but these data do not suggest clinically significant interference.

Due to an increased risk of fever, tenderness at the injection site, change in eating habits and irritability when Bexsero was co-administered with the above vaccines, separate vaccinations can be considered when possible. Prophylactic use of paracetamol reduces the incidence and severity of fever without affecting the immunogenicity of either Bexsero or routine vaccines. The effect of antipyretics other than paracetamol on the immune response has not been studied.

Concomitant administration of Bexsero with vaccines other than those mentioned above has not been studied.

When given concomitantly with other vaccines Bexsero must be administered at separate injection sites (see section 4.2).

4.6. Fertility, pregnancy and lactation

Pregnancy

Insufficient clinical data on exposed pregnancies are available.

The potential risk for pregnant women is unknown. Nevertheless, vaccination should not be withheld when there is a clear risk of exposure to meningococcal infection.

There was no evidence of maternal or foetal toxicity, and no effects on pregnancy, maternal behaviour, female fertility, or postnatal development in a study in which female rabbits received Bexsero at approximately 10 times the human dose equivalent based on body weights.

Breast-feeding

Information on the safety of the vaccine to women and their children during breast-feeding is not available. The benefit-risk ratio must be examined before making the decision to immunise during breast-feeding.

No adverse reactions were seen in vaccinated maternal rabbits or in their offspring through day 29 of lactation. Bexsero was immunogenic in maternal animals vaccinated prior to lactation, and antibodies were detected in the offspring, but antibody levels in milk were not determined.

Fertility

There are no data on fertility in humans.

There were no effects on female fertility in animal studies.

4.7. Effects on ability to drive and use machines

Bexsero has no or negligible influence on the ability to drive and use machines. However, some of the effects mentioned under section 4.8 “Undesirable effects” may temporarily affect the ability to drive or use machines.

4.8. Undesirable effects

Summary of the safety profile

The safety of Bexsero was evaluated in 17 studies including 10 randomised controlled clinical trials with 10 565 subjects (from 2 months of age) who received at least one dose of Bexsero. Among Bexsero recipients, 6 837 were infants and children (less than 2 years of age), 1 051 were children (2 to 10 years of age) and 2 677 were adolescents and adults. Of the subjects who received primary infant series of Bexsero, 3 285 received a booster dose in the second year of life.

In infants and children (less than 2 years of age) the most common local and systemic adverse reactions observed in clinical trials were tenderness and erythema at the injection site, fever and irritability.

In clinical studies in infants vaccinated at 2, 4 and 6 months of age, fever (≥ 38 °C) was reported by 69% to 79% of subjects when Bexsero was co-administered with routine vaccines (containing the following antigens: pneumococcal 7-valent conjugate, diphtheria, tetanus, acellular pertussis, hepatitis B, inactivated poliomyelitis and Haemophilus influenzae type b) compared with 44% to 59% of subjects receiving the routine vaccines alone. Higher rates of antipyretic use were also reported for infants vaccinated with Bexsero and routine vaccines. When Bexsero was given alone, the frequency of fever was similar to that associated with routine infant vaccines administered during clinical trials. When fever occurred, it generally followed a predictable pattern, with the majority resolving by the day after vaccination.

In adolescents and adults, the most common local and systemic adverse reactions observed were pain at the injection site, malaise and headache.

No increase in the incidence or severity of the adverse reactions was seen with subsequent doses of the vaccination series.

Tabulated list of adverse reactions

Adverse reactions (following primary immunisation or booster dose) considered as being at least possibly related to vaccination have been categorised by frequency.

Frequencies are defined as follows:

Very common:

Common:

Uncommon:

Rare:

(<1/10,000)

(cannot be estimated from the available data)

Within each frequency grouping, undesirable effects are presented in order of decreasing seriousness.

In addition to reports in clinical trials, worldwide voluntary reports of adverse reactions received for Bexsero since market introduction are included in the list. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency and they are consequently listed with the frequency unknown.
