The meningococcal vaccine is typically given once in adolescence with a booster at 16, but schedules vary based on age and risk factors.
Understanding the Meningococcal Vaccine Schedule
The meningococcal vaccine protects against meningococcal disease, a serious bacterial infection that can cause meningitis and bloodstream infections. Knowing how often you need to get this vaccine is crucial for maintaining protection, especially during high-risk years.
Generally, the Centers for Disease Control and Prevention (CDC) recommends that all preteens and teens receive the first dose of the meningococcal conjugate vaccine (MenACWY) at 11 or 12 years old. A booster shot is then given at age 16 to maintain immunity through late adolescence when the risk of infection peaks.
This two-dose schedule is designed to provide long-lasting protection during teenage years, which are considered a vulnerable period due to increased social interaction and behaviors that facilitate the spread of bacteria. However, this schedule can differ for younger children, adults with certain medical conditions, or those traveling to areas where meningococcal disease is more common.
Primary Series and Booster Timing
The initial dose primes the immune system, while the booster strengthens and prolongs immunity. If the first dose is administered after age 16, a booster isn’t necessary because one dose at this age offers sufficient protection.
For children under 7 who are at increased risk (due to medical conditions like asplenia or complement component deficiencies), a different vaccination schedule applies. These children may require multiple doses spaced out over time to ensure adequate protection.
Different Types of Meningococcal Vaccines and Their Schedules
There are two main types of meningococcal vaccines used in the United States:
- MenACWY (Meningococcal Conjugate Vaccine): Protects against serogroups A, C, W, and Y.
- MenB (Meningococcal Serogroup B Vaccine): Protects against serogroup B.
Both vaccines target different strains of Neisseria meningitidis bacteria but are administered separately because they protect against distinct groups.
MenACWY Vaccine Schedule
MenACWY is routinely recommended for all adolescents with a primary dose at 11-12 years old and a booster at 16. For those who missed their first dose before age 16, it’s advised to get vaccinated as soon as possible with a single dose if older than 16.
Certain high-risk groups receive MenACWY earlier or more frequently:
- Children aged 2 months to 10 years with specific health conditions may need multiple doses spaced several months apart.
- Adults with certain medical risks might require periodic boosters every five years.
- Travelers to endemic regions, like parts of Africa or Saudi Arabia during Hajj season, often get vaccinated before travel.
MenB Vaccine Schedule
The MenB vaccine is usually recommended for people aged 16-23 years based on shared clinical decision-making rather than universal vaccination. The dosing schedule depends on which MenB vaccine brand is used:
- Bexsero: Two doses given at least one month apart.
- Trumenba: Either two or three doses depending on risk factors and timing.
Unlike MenACWY, there’s no routine booster recommendation for MenB unless ongoing risk exists.
Meningococcal Vaccination in Special Populations
Certain individuals require tailored vaccination schedules due to increased susceptibility or exposure risks.
Younger Children and Infants
Infants under two years old have higher vulnerability but don’t routinely get MenACWY unless they have health risks. Instead, infants may receive MenB vaccines if indicated by their doctor. The dosing for young children involves multiple shots over several months to build strong immunity.
People with Medical Conditions
Conditions like functional or anatomical asplenia (absence or malfunction of spleen), complement component deficiencies, or immunocompromising disorders increase meningitis risk dramatically. For these individuals:
- The MenACWY vaccine series begins earlier—often starting at two months old.
- Booster doses are given every five years instead of just once during adolescence.
- The MenB vaccine series may also be recommended routinely.
Travelers and Outbreak Situations
Travelers heading to countries where meningitis outbreaks occur—such as sub-Saharan Africa’s “meningitis belt”—should get vaccinated before departure. In outbreak settings within communities or college campuses, health authorities may recommend additional doses or catch-up vaccinations regardless of age.
Meningococcal Vaccine Effectiveness Over Time
The effectiveness of meningococcal vaccines can wane over time. That’s why booster shots are critical for sustaining immunity through late adolescence when exposure risk spikes.
Studies show that antibody levels decline within five years after the initial MenACWY dose in early adolescence. The booster shot at age 16 restores protection by increasing antibody levels back up significantly.
For high-risk adults who received their primary series as children or teens, boosters every five years help maintain protective immunity throughout adulthood.
MenB vaccines offer good short-term protection but long-term data is still emerging regarding duration. Currently, no routine boosters are recommended unless ongoing risk exists.
Meningococcal Vaccine Side Effects and Safety Profile
These vaccines have been widely studied and found safe across all age groups. Most side effects are mild and temporary:
- Pain or redness at injection site
- Mild fever
- Tiredness or headache
- Mild muscle aches
Severe allergic reactions are rare but possible with any vaccine. Healthcare providers monitor patients closely after vaccination for any immediate adverse effects.
Overall, benefits far outweigh risks since meningitis can cause severe complications including brain damage or death if not prevented.
The Importance of Staying Up-to-Date: How Often Do You Have to Get the Meningococcal Vaccine?
Keeping your vaccinations current ensures continuous protection against potentially life-threatening infections. Adolescents should get their first MenACWY shot between ages 11-12 followed by a booster at 16 unless they receive their first dose later—in which case only one dose after age 16 is needed.
Those with medical conditions must follow specialized schedules involving multiple doses starting in infancy plus boosters every five years throughout life.
Travelers headed to high-risk areas should be vaccinated prior to departure even if previously immunized years ago.
Here’s a clear summary table outlining typical vaccination timing based on age group and risk:
| Age Group / Risk Category | MenACWY Dose(s) | MenB Dose(s) |
|---|---|---|
| Ages 11-12 (Routine) | 1st dose now + booster at 16 yrs old | Optional; shared decision-making (ages 16-23) |
| Ages ≥16 without prior MenACWY doses | Single dose; no booster needed afterward | Optional; shared decision-making (ages 16-23) |
| Younger children with health risks (<7 yrs) | Multiple doses starting from infancy; boosters every 5 yrs | If indicated; multiple doses per brand schedule |
| Adults with ongoing risk (e.g., asplenia) | Doses every 5 yrs indefinitely | If indicated; per provider recommendation |
| Travelers to endemic areas | Dose prior to travel; boosters if>5 yrs since last | Dose if recommended based on destination |

Frequently Asked Questions
How often do you have to get the meningococcal vaccine during adolescence?
The meningococcal vaccine is typically given twice during adolescence. The first dose is recommended at 11 or 12 years old, followed by a booster shot at age 16. This schedule helps maintain protection when the risk of infection is highest in late teenage years.
How often do you have to get the meningococcal vaccine if you miss the first dose before age 16?
If the first meningococcal vaccine dose is missed before age 16, it’s advised to get vaccinated as soon as possible. A single dose after age 16 provides sufficient protection, so no booster is necessary in this case.
How often do you have to get the meningococcal vaccine for children under 7 with risk factors?
Children under 7 with certain medical conditions may require multiple doses of the meningococcal vaccine spaced over time. This different schedule ensures they receive adequate protection due to their increased vulnerability to infection.
How often do you have to get the meningococcal vaccine if you belong to a high-risk group?
High-risk groups may need to receive the meningococcal vaccine earlier or more frequently than the standard schedule. The exact timing depends on specific risk factors such as medical conditions or travel to areas with higher disease prevalence.
How often do you have to get both types of meningococcal vaccines?
The MenACWY vaccine is given routinely with two doses during adolescence, while the MenB vaccine is administered separately and on a different schedule. Both target distinct bacterial strains and may be recommended based on individual risk assessments.
The Bottom Line – How Often Do You Have to Get the Meningococcal Vaccine?
For most people, getting the meningococcal vaccine means one shot around age 11-12 followed by a booster at age 16 — that’s it for routine protection against serogroups A, C, W, and Y. If you miss this window but still want coverage after turning sixteen, just one dose will do fine without needing a booster later on.
If you have special medical conditions or travel plans that put you at higher risk, your doctor will likely recommend an adjusted schedule involving earlier shots and recurring boosters every five years — sometimes starting from infancy!
Serogroup B requires its own separate vaccination series usually between ages sixteen and twenty-three depending on personal risk factors. Unlike MenACWY vaccines though, routine boosters aren’t typically necessary unless continued exposure demands it.
Staying informed about your vaccination status ensures you’re shielded from invasive meningitis caused by these dangerous bacteria — so check your records regularly! Understanding exactly how often do you have to get the meningococcal vaccine helps keep you safe through critical stages in life without guesswork or confusion.
