Can a child vaccinated with Bexsero infect immunocompromised people and is it a live vaccine?

A child vaccinated with Bexsero does not infect immunocompromised people or other people from his environment. It is not a live vaccine. Bexsero is a protein vaccine developed using reverse vaccinology technology, where proteins that have been shown to be good antigens in the vaccine, i.e. factor H, adhesin A and heparin-binding antigen, have been identified based on the known sequence of the entire genome of meningococcal serogroup B; the vaccine also includes a surface protein prepared by the traditional method. The vaccine works by sensitizing the immune system. When the vaccine is administered, the immune system recognizes the bacterial fragments contained in the vaccine as foreign and produces antibodies against them. After contact of the vaccinated person with bacteria, antibodies along with other components of the immune system will be able to neutralize these bacteria.
