Two types of meningococcal vaccines are already available in the U.S. Some protect against serogroups A,C, W and Y, while other shots, like Trumenba, protect against serogroup B.
The Centers for Disease Control and Prevention recommends children aged 11 or 12 receive a MenACWY conjugate vaccine, followed by a booster at age 16. People 10 years or older who are at higher risk of meningococcal disease should receive a vaccine against serogroup B, according to the CDC.
