The meningitis B vaccine is not required for college enrollment in most states. While at least 22 states mandate some form of meningococcal vaccination for college students, the vast majority of those laws refer to the MenACWY vaccine, which covers four strains of meningococcal bacteria but not serogroup B. The meningitis B (MenB) vaccine is a separate shot, and the CDC classifies it as a “shared clinical decision” for teens and young adults rather than a routine requirement.
That distinction matters more than it might seem. Even though few schools legally require it, there are strong reasons college-bound students should understand what the MenB vaccine does and why health officials still recommend considering it.
What Most States Actually Require
State laws about meningococcal vaccines for college students vary widely, but they share a common pattern: when a state mandates meningococcal vaccination, it typically means the MenACWY vaccine, not the MenB vaccine. States like Connecticut, Hawaii, Illinois, Louisiana, Massachusetts, and North Dakota specifically reference the meningococcal conjugate (ACWY) vaccine in their requirements. Florida, Indiana, Kansas, Maryland, Missouri, and Oklahoma require meningococcal vaccination for students living in on-campus housing, and in practice this also means MenACWY.
Some states take an even lighter approach. California and Colorado require colleges to provide information about both MenACWY and MenB disease but stop short of mandating vaccination. Iowa similarly requires institutions with on-campus housing to share vaccine information without requiring the shots themselves. Georgia gives students the option to review information and waive vaccination altogether.
Individual universities can and do set their own policies beyond state law. Some schools, particularly after experiencing an outbreak, require or strongly recommend the MenB vaccine for incoming students. Always check your specific college’s immunization portal, because university requirements may be stricter than your state’s minimum.
MenACWY vs. MenB: Two Different Vaccines
Meningococcal disease is caused by several serogroups of bacteria, and no single vaccine covers all of them. The MenACWY vaccine protects against serogroups A, C, W, and Y. The MenB vaccine protects against serogroup B. These are completely separate shots, and getting one does not provide any protection against the strains covered by the other.
The CDC recommends MenACWY as a routine vaccination for all adolescents, with a first dose at age 11 or 12 and a booster at 16. This is the shot most states require for college. The MenB vaccine, by contrast, falls into a category the CDC calls “shared clinical decision-making,” meaning it’s recommended that teens and young adults between 16 and 23 discuss it with a healthcare provider and decide whether to get it. It is not on the routine schedule for all adolescents.
A newer combination vaccine now covers all five serogroups (A, B, C, W, and Y) in a single product, which may simplify the process for students who haven’t yet received either shot.
Why Serogroup B Matters on Campus
Despite not being universally required, the MenB vaccine addresses a real and specific risk for college students. Between 2013 and 2018, ten meningococcal disease outbreaks occurred on U.S. university campuses, and every single one was caused by serogroup B. Those outbreaks resulted in 39 cases and 2 deaths. This shift happened in part because MenACWY coverage among adolescents is now high, which has reduced outbreaks from serogroups A, C, W, and Y while leaving serogroup B as the primary remaining threat in college settings.
College dormitories create conditions where meningococcal bacteria spread more easily: close quarters, shared living spaces, and social behaviors common among young adults. The bacteria transmit through saliva and close contact, making residential campus life a higher-risk environment compared to the general population.
Dosing and Timing Before College
Both available MenB vaccines require multiple doses, and you need to use the same brand for all doses in the series. The standard schedule is two doses given six months apart. If you’re starting the vaccine less than six months before moving into a dorm, the CDC recommends a three-dose schedule: the first dose right away, a second dose one to two months later, and a third dose at six months. This accelerated schedule provides faster initial protection while still completing the full series.
One important rule: if the third dose ends up being given less than four months after the second dose, it needs to be repeated at least four months later (unless it was already at least six months after the first dose). Planning ahead avoids this complication. Ideally, students should start the series during junior year of high school to have full protection well before freshman move-in day.
Cost and Insurance Coverage
Under the Affordable Care Act, marketplace plans and most private insurance plans must cover recommended vaccines with no copay, coinsurance, or deductible when administered by an in-network provider. Meningococcal vaccines, including MenB, fall under this coverage. If your child is on a parent’s insurance plan, the vaccine should be fully covered at an in-network pharmacy or doctor’s office.
Exemptions If Your School Requires It
Every state that mandates vaccines for college enrollment allows exemptions, though the types vary. Medical exemptions are available everywhere and require a licensed physician to document that a health condition makes vaccination unsafe. Most states also allow religious exemptions, which typically involve submitting a written statement to the school explaining that vaccination conflicts with sincerely held religious beliefs. Some states accept philosophical or personal belief exemptions as well, while others, like North Carolina, limit exemptions to medical and religious grounds only.
The process is generally straightforward. Medical exemptions require a form signed by your doctor. Religious exemptions usually require a written statement that includes the student’s name, date of birth, and the reason for the objection. These documents go directly to the college, not to a state agency. Specific requirements vary by state and institution, so check with your school’s health services office for the exact paperwork needed.
The Bottom Line on Whether You Need It
Legally, most college-bound students are not required to get the MenB vaccine. The vaccine that states and schools typically mandate is MenACWY. But “not required” and “not recommended” are different things. Serogroup B is now responsible for every known university meningococcal outbreak in the U.S. since 2011, and the disease can progress from mild symptoms to life-threatening illness within hours. The CDC recommends that all 16- to 23-year-olds consider the vaccine, with 16 to 18 being the preferred age range for maximum benefit heading into college.
