Drug overview for BEXSERO (meningococcal group b vaccine, 4-component):

Generic name: MENINGOCOCCAL GROUP B VACCINE, 4-COMPONENT (MEN-in-go-COC-al)
Drug class: Meningococcal Vaccines - Serogroup B
Therapeutic class: Biologicals

Meningococcal group B (MenB) vaccine is an inactivated (recombinant) vaccine that is commercially available in the US as 2 different vaccines containing antigens derived from Neisseria meningitidis serogroup B. MenB-4C (Bexsero(R)) contains 3 recombinant cell surface proteins (neisserial adhesion A (NadA), neisserial heparin-binding antigen (NHBA), factor H-binding protein (FHbp)) and outer membrane vesicles (OMV) containing outer membrane protein PorA (serosubtype P1.4) derived from N. meningitidis serogroup B.

MenB-FHbp (Trumenba(R)) contains 2 FHbp variants, one from FHbp subfamily A (A05) and one from FHbp subfamily B (B01), derived from N. meningitidis serogroup B. MenB vaccine is used to stimulate active immunity to infection caused by N. meningitidis serogroup B.

The dosing schedule (i.e., number and timing of doses) differ between MenB-4C (Bexsero(R)) and MenB-FHbp (Trumenba(R)) and may depend on the individual's risk of exposure and susceptibility to Neisseria meningitidis serogroup B. Recommendations for the specific vaccine used should be followed.

The manufacturers state that data available to date are insufficient regarding the interchangeability of MenB-4C and MenB-FHbp. The US Public Health Service Advisory Committee on Immunization Practices (ACIP) and American Academy of Pediatrics (AAP) state that MenB-4C and MenB-FHbp are not interchangeable and recommend that the MenB vaccine used for the initial dose should be used to complete the vaccination series.

Meningococcal group B (MenB) vaccine is administered as MenB-4C (Bexsero(R)) or MenB-FHbp (Trumenba(R)). MenB-4C and MenB-FHbp are administered only by IM injection. Syncope (vasovagal or vasodepressor reaction; fainting) may occur following vaccination.

Syncope occurs most frequently in adolescents and young adults. Procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope. Syncope and secondary injuries may be averted if vaccinees sit or lie down during and for 15 minutes after vaccination.

If syncope occurs, the patient should be observed until symptoms resolve. MenB vaccine may be given simultaneously with other age-appropriate vaccines. When multiple vaccines are administered during a single health-care visit, each parenteral vaccine should be given with a different syringe and at different injection sites. Injection sites should be separated by at least 1 inch (if anatomically feasible) to allow appropriate attribution of any local adverse effects that may occur.

Drug Interaction	Drug Names
Non-Live or Non-Replicating Vaccines/Teplizumab SEVERITY LEVEL: 2-Severe Interaction: Action is required to reduce the risk of severe adverse interaction. MECHANISM OF ACTION: Teplizumab may cause lymphopenia and alter the immune system's response to vaccines.(1) CLINICAL EFFECTS: Administration of a non-live vaccine within the 2 weeks prior to, during, or for 6 weeks following teplizumab therapy may result in decreased effectiveness of the vaccine.(1) PREDISPOSING FACTORS: None determined. PATIENT MANAGEMENT: Ideally, administer vaccines prior to initiating teplizumab therapy. The manufacturer of teplizumab states that non-live vaccines (e.g., inactivated or mRNA vaccines) are not recommended within the 2 weeks prior to, during, or for 6 weeks after stopping teplizumab therapy.(1) The immune response to non-live vaccines should be monitored in patients who receive teplizumab within these time frames. The Centers for Disease Control's (CDC) Advisory Committee on Immunization Practices (ACIP) states that non-live vaccines should be used with caution in patients who are severely immunosuppressed. Patients who are vaccinated within the 14 days prior to initiating immunosuppressive therapy should be considered unvaccinated and should be revaccinated at least 3 months after immunosuppressive therapy is discontinued when immune competence is restored.(2) For COVID-19 vaccines, the CDC advises planning for vaccination at least 2 weeks before starting or resuming immunosuppressive therapy. Patients should be offered and given a COVID-19 vaccine even if the use and timing of immunosuppressive agents cannot be adjusted. The CDC states that an age-appropriate mRNA COVID-19 vaccine is preferred over the Janssen COVID-19 vaccine for the primary and booster doses for immunocompromised patients. All immunocompromised patients over 5 years of age should receive at least 1 booster dose if eligible. See the CDC's Interim Clinical Considerations for Use of COVID-19 Vaccines for age- and product-specific recommendations.(3) DISCUSSION: Vaccinations may be less effective if administered within 2 weeks before, during, and for 6 weeks following teplizumab therapy.(1)	TZIELD
