What Are The Risks From Meningococcal Vaccine
Most people have mild side effects from the vaccine, such as redness or pain where the shot was given. A vaccine, like any medicine, may cause serious problems, such as severe allergic reactions. This risk is extremely small. Getting the meningococcal vaccine is much safer than getting the disease.
You can learn more on the Vaccine Information Statements for meningococcal ACWY and meningococcal B.
What Is Meningococcal Disease
Meningococcal disease is a serious illness caused by a bacterium. It can cause meningitis, which is an infection of the brain and spinal cord, and it can also cause blood infections. The infection can cause death or lifelong disability.
About 375 people get the disease each year, and about 10 to 15 out of 100 people infected with meningococcal disease die. Of those who survive, up to one out of five will have permanent disabilities, such as deafness, brain damage, loss of limbs, or seizures.
A person with meningococcal disease may become seriously ill very quickly. Antibiotics can treat meningococcal infections, but often can’t be given soon enough to help.
Anyone can get meningococcal disease, but it is most common in infants less than 1 year of age. Teens are less likely to be infected than infants, but disease levels increase in adolescence starting around age 11, and peak around age 19 years.
Why Should A Baby Be Vaccinated
MenB infection is most common in babies and young children. This is because their immune systems arent yet fully developed to fight off infection. The highest number of cases are in babies around 5 months of age. This is why the first immunisations are offered to babies younger than this and have to be given at 2 and 4 months of age.
This vaccine helps protect babies against MenB, There are other vaccines, like MenC, that protect against some other types of meningococcal infections.

Special Considerations For Use Of Menactra For People With Functional Or Anatomic Asplenia Or Hiv
Children with functional or anatomic asplenia or HIV should not receive Menactra® before the age of 2 years. This timing avoids interference with the immunologic response to the infant series of pneumococcal conjugate vaccine . CDC recommends infants 2 through 23 months of age with functional or anatomic asplenia or HIV receive Menveo®.
People 2 years of age or older with functional or anatomic asplenia or HIV should not receive Menactra® at the same time as PCV. They should either receive Menveo® or MenQuadfi® when they get PCV or wait and receive Menactra® 4 weeks after completion of all PCV doses.
Who Should Get Meningococcal Vaccines
CDC recommends meningococcal vaccination for all preteens and teens. In certain situations, CDC also recommends other children and adults get meningococcal vaccines. Below is more information about which meningococcal vaccines, including booster shots, CDC recommends for people by age.
Talk to your or your childs doctor about what is best for your specific situation.

Cdc Recommends Meningococcal Vaccination For People Identified As Being At Increased Risk During Outbreaks
CDC supports state and local health departments in investigating outbreaks and implementing outbreak control measures. During a serogroup A, C, W, or Y meningococcal disease outbreak, CDC recommends MenACWY vaccination for people at increased risk because of the outbreak. During a serogroup B meningococcal disease outbreak, CDC recommends MenB vaccination for people at increased risk because of the outbreak. People who have previously received MenACWY or MenB vaccine and become at increased risk because of an outbreak may be recommended to receive a booster dose depending on how long it has been since they previously received the vaccine.
Why The Meningitis B Vaccine Is Used
There are many reasons that the meningitis B vaccine was developed and why you would want to protect yourself and those you love against it.
Meningitis B is a serious disease that progresses quickly and can lead to death. The mortality rate from meningitis B in the United States is about 10 to 15 percent when treated and up to 50 percent when untreated. Its also possible to develop long-term conditions such as hearing loss or even brain damage after recovering from meningitis B.
The MenB bacterial infection is passed between people through saliva and respiratory fluids. Activities like sharing drinks, kissing, or coughing can spread the bacterium. The meningitis B vaccine can help reduce transmission between people and prevent or manage outbreaks.
Unlike many diseases, meningitis B is most common in young people. Infants and young children are at the highest risk. Adolescents and young adults are at the next highest risk of infection.
Between 2013 and 2018, meningococcal disease outbreaks occurred at 10 universities and led to two deaths. All 10 universities implemented MenB vaccination to prevent further spread.

Managing Fever After Meningococcal Acwy Immunisation
Common side effects following immunisation are usually mild and temporary . Specific treatment is not usually required.
If fever is present, drinking extra fluids and not overdressing can help.
Although routine use of paracetamol after vaccination is not recommended , if fever is present, paracetamol can be given. Check the label for the correct dose according to your childs weight or speak with your pharmacist, especially when giving paracetamol to children.
Are Free Or Low
Yes, if you don’t have insurance or your insurance does not cover the cost of the meningococcal vaccines, you may be able to find free or low-cost meningococcal shots.
- Talk to your doctor or clinic to see if they participate in the Minnesota Vaccines for Children Program. If the person in need of vaccination is 18 years old or younger, they may be eligible for no-cost vaccines. However, there may be an administration fee of up to $21.22 per shot.
- Talk to your city or county health department. They may be able to provide low-cost meningococcal shots.

How Do We Know The Vaccine Is Safe
Before they’re allowed to be used, all vaccines are carefully tested for safety and effectiveness. They’ve been through trials in the laboratory and among volunteers.
The UK is the first country to introduce the MenB vaccine into its routine immunisation schedule for children. The vaccine is already offered to children in the UK with certain medical conditions and has also been used to contain outbreaks of MenB disease. It has been proved to be both safe and effective.
Menb Vaccination Of Adolescents
Adolescents and young adults may also receive a serogroup B meningococcal vaccine. The preferred age for receipt is 16 through 18 years so adolescents have protection during the ages of increased risk.
Patients taking complement inhibitors, such as eculizumab or ravulizumab , are at increased risk for meningococcal disease. These patients may still contract meningococcal disease despite being fully vaccinated or receiving antimicrobial prophylaxis.
CDC recommends that certain adolescents and young adults should receive a serogroup B meningococcal vaccine. They include those at increased risk because of a serogroup B meningococcal disease outbreak and people with certain medical conditions or taking certain medications. These include
- Complement component deficiency
- Functional or anatomic asplenia
- Complement inhibitor
Those at increased risk need regular booster doses.
- Administer a booster dose of MenB vaccine 1 year after series completion and then every 2 to 3 years thereafter.
- For those at increased risk due to an outbreak who previously received the MenB vaccine series, CDC recommends a booster dose if a year or more has passed since primary series completion.

Common And Local Adverse Events
Conjugate meningococcal vaccines
Injection site reactions occur in up to 59% of vaccinees. Fever is reported in up to 5% of recipients and systemic reactions, such as headache and malaise, are reported in up to 60% of recipients.
Mild reactions, including injection site reactions , occur in up to 50% of vaccine recipients. Irritability occurs in up to 80% of infants and fever in up to 9% when other vaccines were administered. Headaches and malaise occur in up to 10% of older children and adults. These reactions last no more than a few days.
Serogroup B Meningococcal vaccines
Solicited local and systemic reactions have been commonly reported in clinical trials and include injection site tenderness, induration, sleepiness and irritability. Higher rates of fever have been observed with simultaneous administration of 4CMenB vaccine and routine infant vaccines therefore, routine prophylactic administration of acetaminophen or separating 4CMenB vaccination from routine vaccination schedule has been proposed for preventing fever in infants and children up to three years of age.
Solicited local and systemic reactions have been commonly reported in clinical trials and include injection site tenderness, induration and irritability.
What Are The Different Types Of Vaccines For Meningitis B
In the United States, two types of meningitis B vaccines are Food and Drug Administration -approved Bexsero and Trumenba.
To receive FDA approval, both vaccines had to undergo clinical trials showing their safety and effectiveness. Both vaccines work in a similar way but use different proteins to stimulate your immune response.
Bexsero is produced by GlaxoSmithKline. Its administered in two 0.5 milligram doses, 1 month apart.
Before approval, safety data was reviewed from 3,139 subjects in clinical trials in the United States, Canada, Australia, Chile, the United Kingdom, Poland, Switzerland, Germany, and Italy. Additional safety information was collected from 15,351 people who received Centers for Disease Control and Prevention sponsored vaccines at universities.
Trumenba is produced by Pfizer and is administered in two to three doses. For the three-dose schedule, the second dose is administered 1 to 2 months after the first, and the third vaccine is given 6 months after the first dose. For the two dose schedule, the second dose is given at 6 months after the first.
Before the FDA approved Tremenba, reviewers examined
People who have the highest chance of getting meningitis B include:
In the U.S. meningitis B vaccine isnt available yet for infants younger than 1 year old but is administered in the United Kingdom as part of the National Health Service vaccination schedule.

Persons New To Canada
Health care providers who see persons newly arrived in Canada should review the immunization status and update immunization for these individuals. Review of meningococcal vaccination status is particularly important for persons from areas of the world where sickle cell disease is present as persons with sickle cell disease are at risk of serious meningococcal infections. In many countries outside of Canada, conjugate meningococcal vaccines are in limited use. Information on vaccination schedules in other countries can be found on the World Health Organization website. Refer to Immunization of Persons New to Canada in Part 3 for additional general information.
Why Do Teens Need A Meningococcal Vaccine
Of the 1,000-2,600 people who get meningococcal disease each year, one-third are teens and young adults. Ten percent to 15% of those who get sick with the disease will die, even with antibiotic treatment. As many as 20% of the survivorswill have permanent side effects, such as hearing loss or brain damage.
The immunization can help prevent this serious disease.

Microbiological And Clinical Overview
N. meningitidis is a Gram-negative aerobic diplococcus, hosted exclusively by men. It is an opportunistic pathogen, usually living as a commensal in the nasopharynx, colonizing the upper respiratory tract, without causing damage to the host.6,7 The highest rates of nasopharyngeal carriage are reported in adolescents and young adults. The asymptomatic carriage prevalence increases from 4.5% in childhood, with a peak of 23.7% in 19-year-old individuals, and then decreases to 78% in adulthood.8 The different N. meningitidis strains are divided in 12 serogroups on the basis of the capsular polysaccharides immuno-histochemical characteristics serogroups A, B, C, W, and Y are responsible for most IMD cases worldwide. Further classification into serotypes/subserotypes or immunotypes is established on major outer membrane class 1 and class 2 or 3 proteins or on lipopolysaccharides , respectively.9
Every year MenB causes 500,000 cases of septicemia and meningitis worldwide although the incidence of the invasive form is generally low, it is matter of great concern for health professionals due to the quick onset and course of the disease, the difficult of early diagnosis, the major post-infection sequelae , and high fatality rates .14,1618
Where Can I Find These Vaccines
Your doctor is usually the best place to receive recommended vaccines for you or your child. These vaccines are part of the routine childhood immunization schedule. Therefore, vaccines for children and teens are regularly available at
- Pediatric and family practice offices
- Community health clinics
If your doctor does not have these vaccines for adults, ask for a referral.
Vaccines may also be available at
- Health departments
- Other community locations, such as schools and religious centers
You can also contact your state health department to learn more about where to get vaccines in your community.
When receiving any vaccine, ask the provider to record the vaccine in the state or local vaccine registry, if available. This helps providers at future visits know what vaccines you or your child have already received.

Who Needs To Get Vaccinated For Meningitis
Its especially important for you to keep all of your meningitis vaccinations up-to-date if you fall into a high-risk category for getting the disease. High-risk categories include:
- Certain Ages. Infants less than one-year-old and young adults between the ages of 16 and 21 are the most likely to develop meningitis. Its most important to have all boosters and available vaccinations at these ages.
- Crowded Settings. Large group settings like college campuses are where outbreaks of meningitis are the most common. Get your vaccines up-to-date before entering into these settings for extended periods of time.
- Certain underlying conditions. Some underlying medical conditions can increase your chance of getting meningitis. These include HIV and other conditions that weaken your immune system. Not having a spleen also places you at higher risk.
- Work that involves meningitis-causing agents. Microbiologists and any other researchers that regularly come into contact with the bacteria and viruses that cause meningitis are consistently at risk.
- Travel to certain areas. Some areas in the world like sub-Saharan Africa have higher rates of meningitis and the pathogens that cause it. Check with your doctor before traveling to new parts of the world.
You Are Pregnant Or Breastfeeding
- Pregnant women who are at increased risk for serogroup A, C, W, or Y meningococcal disease may get MenACWY vaccines.
- Pregnant or breastfeeding women who are at increased risk for serogroup B meningococcal disease may get MenB vaccines. However, they should talk with a doctor to decide if the benefits of getting the vaccine outweigh the risks.

Are There Times You Shouldn’t Get The Vaccine
Typically, you want to avoid getting it if you:
- Are very sick. A mild cold is OK, but for anything more than that, it’s better to hold off.
- Had a severe, life-threatening allergy to a meningitis vaccine or some part of it. Your doctor can tell you what’s in the vaccine.
- Had a severe reaction to the DTap vaccine or latex
- Have Guillain-Barre syndrome. Ask your doctor if the vaccine is safe for you.
- Have a latex allergy
May be pregnant or are breastfeeding. It’s typically best to avoid the vaccine in this case, but if it’s needed, your doctor can help weigh the pros and cons.
Simultaneous Administration With Other Vaccines
Men-C-C and 4CMenB vaccine may be administered concomitantly with routine childhood vaccines, and Men-C-ACYW vaccine may be administered concomitantly with adolescent and adult age appropriate vaccines. MenB-fHBP can be given concomitantly with quadrivalent human papillomavirus vaccine meningococcal serogroup A, C, Y, W conjugate vaccine and tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine adsorbed. The concomitant administration of MenB-fHBP has not been studied with other vaccines.
Men-C-ACYW-CRM can be administered with routine paediatric vaccines however, further studies are needed with regard to concomitant administration with pneumococcal 13-valent conjugate vaccine. Co-administration of Men-C-ACYW-CRM and combined tetanus toxoid, reduced diphtheria toxoid and acellular pertussis vaccine may result in a lower immune response to the pertussis antigens than when Tdap vaccine is given alone however, the clinical significance of this is unknown. Tdap vaccine given one month after Men-C-ACYW-CRM induces the strongest immunologic response to pertussis antigens.
If vaccines are to be administered concomitantly with another vaccine, a separate injection site and a different syringe must be used for each injection.
Refer to Timing of Vaccine Administration in Part 1 for additional general information.
