About one-third of Princeton University students given a vaccine to combat a meningitis B outbreak on campus in 2013 didn’t show signs of protection from the immunization, researchers reported.
However, none of the vaccinated students developed a meningitis infection, the study found.
It was the first-ever use of the meningococcal group B vaccine Bexsero (4CMenB) in the United States. Two-thirds of those who got the vaccine did develop evidence of an immune response against the specific strain that caused the outbreak, the study authors said.
