According to NHS and Green Book guidelines, the meningococcal B vaccine is routinely offered to infants as part of the routine childhood vaccination schedule at 2 months, 4 months, and 12 months of age. Additionally, the vaccine may be recommended for individuals at higher risk, such as those with certain medical conditions or those in close contact with individuals with meningococcal disease.

Common side effects of the meningococcal B vaccine are generally mild and may include redness, swelling, or tenderness at the injection site, as well as fever or irritability. These side effects are usually short-lived and resolve on their own. Serious side effects are rare.

The meningococcal B vaccine is generally safe for most individuals. However, it may be postponed or avoided in cases of severe allergic reaction to a previous dose or to a component of the vaccine. If a person is ill or has a fever at the time of their scheduled vaccination, it may be advisable to delay the vaccine until they have recovered. Consult your healthcare provider for personalized advice.
