Two new vaccines can reduce the spread of meningitis by reducing the number of meningitis-causing bacteria that people carry, according to a new study.
Researchers tested the two vaccines -- MenACWY-CRM and 4CMenB -- on volunteers aged 18 to 24. MenACWY-CRM cut meningitis-causing bacteria populations in the nose and throat by 39 percent and 4CMenB lowered those populations by 20 to 30 percent.
