When Are Meningococcal Vaccines Given
Vaccination with MenACWY is recommended:
- when kids are 11 or 12 years old, with a booster given at age 16
- for teens 1318 years old who haven’t been vaccinated yet
Those who have their first dose between the ages of 1315 should get a booster dose between the ages of 1618. Teens who get their first dose after age 16 won’t need a booster dose.
Kids and teens who are at higher risk for meningococcal disease need the full series of MenACWY vaccines, even if they’re younger than 11 years old. This includes kids who:
- live in or travel to countries where the disease is common
- are present during an outbreak of the disease
- have some kinds of immune disorders. If the immune disorders are chronic, these kids also need a booster dose a few years later, depending on their age at the first dose.
The sequence and dosage depends on the child’s age, medical condition, and vaccine brand. Some types of meningococcal vaccines can be given as early as 8 weeks of age.
Kids 10 years and older with these risk factors also should get the MenB vaccine. They’ll need 2 or 3 doses depending on the brand. They might need more booster doses as long as the risk factor remains.
For those without risk factors, the decision to receive the MenB vaccine should be made together by teens, their parents, and the doctor. For them, the preferred age range is 1618 years. Usually, they need 2 doses.
How Well It Works
The Men-C-C meningococcal vaccine works well. It protects about 97% of infants for one year after they get the vaccine and drops to 70% protection after one year. Booster shots of this vaccine are given to keep the protection level high. The Men-C-ACYW meningococcal vaccine works well and protects about 85% of people from meningococcal disease. The level of protection goes down over a period of years. Not enough information is available to say how long the 4CMenB vaccine protection lasts.
Persons With Inadequate Immunization Records
Children and adults lacking adequate documentation of immunization should be considered unimmunized and started on an immunization schedule appropriate for their age and risk factors. Conjugate meningococcal vaccine, as appropriate for age, may be given regardless of possible previous receipt of the vaccine, as adverse events associated with repeated immunization have not been demonstrated. Refer to Immunization of persons with inadequate immunization records in Part 3 for additional general information.

What To Think About
The menigococcal vaccine can be given at the same time as other routine childhood vaccinations.
The conjugate meningococcal vaccines may be used during pregnancy when the benefits of getting the vaccine outweighs the risk.
The conjugate and multi-component vaccines may be given to women who are breastfeeding.
No evidence has shown that Canadian university students who live in dormitories or residence halls are at higher risk of getting meningococcal disease.footnote 2
Who Needs A Meningococcal Vaccine

The CDC recommends a meningococcal vaccine for:
- All children ages 11-18 or certain younger high-risk children
- Anyone who has been exposed to meningitis during an outbreak
- Anyone traveling to or living where meningitis is common, such as in sub-Saharan Africa
- Military recruits
- People with certain immune system disorders or a damaged or missing spleen

Why Are Meningococcal Vaccines Recommended
Meningococcal disease is caused by a type of bacteria. It can lead to an infection of the bloodstream or meningitis, or both, and can be life-threatening if not quickly treated. The MenACWY vaccine is very effective at protecting against four strains of the bacteria, while the MenB vaccine protects against a fifth strain.
How Common Is Meningococcal Disease
Meningococcal disease is becoming much less common. Over the past 20 years, the overall incidence of meningococcal disease in the US has declined 10-fold. Twenty years ago in Massachusetts there were 80-100 cases of meningococcal disease per year. In contrast, for the past decade the average is approximately 12 cases per year. Declining rates of meningococcal disease may be due in part to the introduction of meningococcal vaccines as well as other factors such as the decline in cigarette smoking, which may impact susceptibility to this disease.

Why Get Immunised Against Meningococcal Disease
Meningococcal disease is a very serious infection that can cause severe scarring, loss of limbs, brain damage and death.
Vaccination is a safe and effective way to protect yourself from meningococcal disease.
Meningococcal disease is most commonly caused by types A, B, C, W and Y. Vaccines can protect against all these types, but different vaccines protect against different types. No single vaccine protects against all types.
Who Should Get Immunised Against Meningococcal Disease
Anyone who wants to protect themselves against meningococcal disease can talk to their doctor about getting immunised.
Anyone wishing to reduce their risk of meningococcal disease can be offered vaccination with meningococcal B and meningococcal ACWY from as early as 6 weeks of age.
Meningococcal immunisation is recommended for:
- babies and young children under 2 years old
- teenagers and young adults aged 15-19 years
- teenagers and young adults aged 15 to 24 years living together in close quarters, such as dormitories and military barracks
- Aboriginal and Torres Strait Islander people aged 2 months to 19 years
- teenagers and young adults aged 15 to 24 years who are current smokers
- people who are travelling overseas to places where meningococcal disease is more common, or people travelling to mass gatherings like the Hajj ,
- people who have medical conditions that increase their risk of invasive meningococcal disease for example, people who have certain blood disorders, or are taking treatment for certain blood disorders people with weakened immune systems, such as people without a functioning spleen, people living with HIV and people who have had a stem cell transplant
- laboratory workers who work with the bacterium that causes meningococcal disease
Speak to your doctor or vaccination provider for advice or refer to the meningococcal recommendations in the Australian Immunisation Handbook for more information and list of medical conditions.

What Are The Options For Meningococcal Vaccine
Meningococcal vaccine is highly effective at protecting against four strains of the meningococcal bacteria. Three strains are common in the United States and the fourth strain protects travelers to certain countries where the disease is more common.
The MenACWY vaccine does not contain the meningococcal B strain that is more commonly found in infants and may cause some cases in adolescents. There is an additional vaccine, meningococcal B vaccine , that contains the B strain. If your clinic does not carry the MenB vaccine, you can ask them to order it for you, or to refer you to another clinic that has the vaccine. Talk to your health care provider about getting this additional vaccine.
Medical Conditions Resulting In High Risk Of Ipd
Table 1: Medical Conditions Resulting in High risk of IPD
Non-immunocompromising conditions
IPD is more common in the winter and spring in temperate climates.
Spectrum of clinical illness
Although asymptomatic upper respiratory tract colonization is common, infection with S. pneumoniae may result in severe disease. IPD is a severe form of infection that occurs when S. pneumoniae invades normally sterile sites, such as the bloodstream or central nervous system. Bacteremia and meningitis are the most common manifestations of IPD in children 2 years of age and younger. Bacteremic pneumococcal pneumonia is the most common presentation among adults and is a common complication following influenza. The case fatality rate of bacteremic pneumococcal pneumonia is 5% to 7% and is higher among elderly persons. Bacterial spread within the respiratory tract may result in AOM, sinusitis or recurrent bronchitis.
Disease distribution
Worldwide, pneumococcal disease is a major cause of morbidity and mortality. The World Health Organization estimates that almost 500,000 deaths among children aged less than 5 years are attributable to pneumococcal disease each year. In Canada, IPD is most common among the very young and adults over 65 years of age.

What Is The Men

The Men-B vaccine protects against infection by one of the most common types of meningococcal bacteria, type B. The vaccine is approved by Health Canada.
The Men-B vaccine is not part of the routine immunization schedule in B.C. However, a vaccine for meningococcal C disease is routinely provided to infants and a vaccine that protects against meningococcal types A, C, Y and W-135 is provided to students in grade 9. Both of these vaccines are provided for free. For more information see HealthLinkBC File #23a Meningococcal C Conjugate Vaccine and HealthLinkBC File #23b Meningococcal Quadrivalent Vaccines.

What Are The Side Effects Of Meningococcal Vaccines
Mild side effects happen in about half those who get the vaccine. They may include redness or pain where the skin was injected. These side effects last no longer than 1 or 2 days.
Serious side effects are rare and can include high fever, weakness, and changes in behavior.
Severe allergic reactions may happen within minutes or hours of having the vaccination. These are signs of an allergic reaction:
Where And When Can I Get The Vaccine
Talk to your doctor or local public health clinic to find out where and when your child should get vaccinated.
- The cost of Men-C-C is covered everywhere in Canada.
- Many provinces currently cover the cost of MCV-4 vaccine.
- Currently, no provinces or territories cover the cost of Men-B vaccine for all children. Some provide it for children at high risk of getting meningococcal disease.

Persons With Chronic Diseases
Asplenia
Two doses of Men-C-ACYW vaccine are recommended for persons with anatomic or functional asplenia, including sickle cell disease. When elective splenectomy is planned, all recommended vaccines should ideally be completed at least 2 weeks before surgery if only one dose can be given before surgery, the second dose should be given 8 weeks after the first dose, with a minimum interval of 4 weeks. In the case of an emergency splenectomy, two doses of vaccine should ideally be given beginning 2 weeks after surgery but can be given earlier, before discharge, if the person might not return for vaccination after discharge. Persons one year of age and older with asplenia who have not received Men-C-ACYW vaccine should receive two doses administered 8 weeks apart, with a minimum interval of 4 weeks. In addition, 4CMenB or MenB-fHBP vaccine should be offered. Periodic booster doses with Men-C-ACYW vaccine are also recommended.
Refer to Table 1 for vaccination recommendations of high risk individuals due to underlying conditions. Refer to Booster doses and re-immunization for additional information and Immunization of Persons with Chronic Diseases in Part 3 for additional general information.
Risks And Possible Side Effects
The shot has a few risks. Side effects are usually mild and go away within a few days. They may include:
- Soreness and swelling at the site of the injection
- Nausea
- Fever or chills
- Rare allergic reactions
You can take over-the-counter pain medicine to ease any pain and swelling after you get the shot.

Who Should Not Get A Meningococcal Vaccine
Your preteen or teen shouldn’t get the meningococcal vaccine if they:
- Has had a severe, life-threatening allergic reaction to a meningococcal vaccine before or to any vaccine component
- Is moderately or severely ill
- Has ever had Guillain-Barre syndrome
Pregnant women can get the meningococcal vaccine, but it’s only recommended for those with certain immune problems or those likely to be exposed to meningitis. With the newer MCV4 and MenB vaccines, there hasn’t been as much study in pregnant women compared to the MPSV4 vaccine.
Are Students Required To Get Meningococcal Vaccine Before College

Yes. Massachusetts law requires the following students receive quadrivalent meningococcal conjugate vaccine :
- Secondary School : newly enrolled full-time students who will be living in a dormitory or other congregate housing licensed or approved by the secondary school must provide documentation of having received a dose of meningococcal conjugate vaccine at any time in the past.
- Postsecondary Institutions : newly enrolled full-time students 21 years of age and younger must provide documentation of having received a dose of quadrivalent meningococcal conjugate vaccine on or after their 16th birthday, regardless of housing status.
Immunizations should be obtained prior to enrollment or registration however, students may be enrolled or registered provided that the required immunizations are obtained within 30 days of registration. There is no requirement for meningococcal B vaccination. However, adolescents and young adults may also be vaccinated with a serogroup B meningococcal vaccine, preferably at 16 through 18 years of age, to provide short term protection for most strains of serogroup B meningococcal disease.
More information about requirements and exemptions may be found in the MDPH document Information about Meningococcal Disease, Meningococcal Vaccines, Vaccination Requirements and the Waiver for Students at Colleges and Residential Schools.

Meningococcal Vaccine For Teens
Experts recommend the meningococcal conjugate vaccine for children when they are age 11 or 12. Teens who have not yet had this shot also need it. That’s especially the case if they are at risk for getting meningitis or have a weakened immune system. Your child should then have a booster shot at age 16, or 5 years after the first vaccine. If your child gets the first shot at age 16 or older, a booster dose is not needed.
Meningococcal Disease: What You Need To Know
What is meningococcal disease?
Meningococcal disease is a very serious bacterial infection caused by the bacterium Neisseria meningitidis. It is a leading cause of bacterial meningitis in children ages 2 through 18 in the United States. Meningitis is an inflammation of the meninges, which are the membranes that enclose the brain and spinal cord.
High fever, headache, vomiting, stiff neck and a rash are common symptoms of meningococcal disease. Among those who develop meningococcal disease, 10 to 15 percent die, despite treatment with antibiotics. Permanent brain damage, hearing loss, kidney failure, loss of arms or legs, or chronic nervous system problems can occur in those who survive.
Anyone can get meningococcal disease, but it is most common in infants less than one year of age and people with certain medical conditions, such as the lack of a spleen. Teenagers aged 15 to 19 and college freshmen who live in dormitories have a higher risk of getting meningococcal disease.
Fortunately, meningococcal disease is not as contagious as the common cold or the flu. The bacteria are spread by respiratory and throat secretions . The bacteria are not spread by casual contact or by simply breathing the air where a person with meningitis has been.
Who needs to be vaccinated?
The following people are at high-risk for meningococcal disease and should get vaccinated:

Guidance On Reporting Adverse Events Following Immunization
To ensure the ongoing safety of vaccines in Canada, reporting of AEFIs by vaccine providers and other clinicians is critical, and in some jurisdictions, reporting is mandatory under the law.
Vaccine providers are asked to report AEFIs, through local public health officials, and to check for specific AEFI reporting requirements in their province or territory. In general, any serious or unexpected adverse event felt to be temporally related to vaccination should be reported.
For additional information about AEFI reporting, please refer to Adverse events following immunization. For general vaccine safety information, refer to Vaccine safety and pharmacovigilance in Part 2.
