Bexsero® Meningitis B Vaccine 2023
GSK's Bexsero® vaccine contains proteins from group B Neisseria meningitidis bacteria. The combination of proteins was chosen to protect against most MenB strains. The U.S. Food and Drug Administration (FDA) initially approved (BL 125546) Bexsero (Meningococcal Group B Vaccine) suspension for intramuscular injection in 2015. The approval of Bexsero was based on the demonstration of the immune response, as measured by serum bactericidal activity against three serogroup B strains representative of prevalent strains in the USA. BEXSERO is approved for 10- through 25-year-olds to prevent meningococcal group B disease (meningitis B) caused by Neisseria meningitidis bacteria.
The U.S. CDC's Advisory Committee on Immunization Practices recommends routine vaccination with a quadrivalent meningococcal conjugate vaccine (MenACWY) for adolescents aged 11 or 12, with a booster dose at age 16. And for people between 16 to 23 receive the Bexsero vaccine based on "shared clinical decision-making." The CDC's 2022 vaccination schedule was posted on February 17, 2022. According to the CDC, different meningococcal vaccines protect people against serogroups A, C, W, and Y. TIn addition, the theGSK vaccination schedule was updated in 2021, and the European Medicines Agency (EMA) issued authorization EMEA/H/C/002333 in 2013.
The global meningococcal vaccines market size is expected to reach USD 4.92 billion by 2030, registering a CAGR of 6.2%.
UK-based GSK is the producer of Bexsero. DrugBank Accession Number: DB10786. STN: BL 125546. BL 125546/824. ATC code: J07AH09.
Bexsero is an FDA-approved vaccine to prevent invasive diseases caused by Neisseria meningitidis serogroup B. As the expression of antigens included in the vaccine is epidemiologically variable in circulating B strains, meningococci that express them at sufficient levels are predicted to be susceptible to killing by vaccine-elicited antibodies.
Bexsro is contraindicated in cases of hypersensitivity, including severe allergic reactions, to any vaccine component after a previous dose of BEXSERO. Effectiveness against various other group B strains has not been confirmed.
Bexsero and Gonorrhea
A study published in Clinical Infectious Diseases on June 1, 2022, suggests that a meningococcal serogroup B vaccine may offer cross-protection against gonorrhea infection.
Bexsero is for intramuscular use only. The recommended immunization series consists of four doses. The primary infant series consists of three doses, given at 2, 4, and 6 months followed by a fourth dose (booster). The primary series can also be given at 2, 3, and 4 months of age, but the immune response to the NHBA antigen is lower.
Apart from active ingredients, the vaccine contains minimal amounts of aluminum, which strengthens and lengthens the immune response to the vaccine, salt (sodium chloride), sugar (sucrose), and an amino acid called histidine, both used as acidity regulators.
Bexsero Side Effects
The most common side effects of aofBEXSERO are pain, redness or hardness at the injection site, muscle pain, fatigue, headache, and nausea. Anyone allergic to these ingredients or severely allergic after a previous dose should not receive BEXSERO.
