What Is Meningococcal Conjugate Vaccine

What Is Meningococcal Conjugate Vaccine

Getting your meningococcal ACWY vaccination at school what to expect

Meningococcal disease is a bacterial infection that can infect the spinal cord and brain and cause meningitis, which can be fatal or lead to permanent and disabling medical problems.

Meningococcal disease spreads from person to person through small droplets of saliva expelled into the air when an infected person coughs or sneezes. The bacteria is usually passed through close contact with an infected person, especially through kissing or sharing a drinking glass or eating utensil.

Meningococcal conjugate vaccine is used to prevent infection caused by serogroups A, C, W, and Y. This vaccine helps your body develop immunity to meningitis, but will not treat an active infection you already have.

The Menactra brand of this vaccine is for use in children and adults between the ages of 9 months and 55 years old. Menveo is for children and adults between the ages of 2 months and 55 years old. MenQuadfi is for adults and children at least 2 years old.

Like any vaccine, meningococcal conjugate vaccine may not provide protection from disease in every person.

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

  • Pharmacies
  • 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.

What Are The Side Effects Of Meningococcal Conjugate Vaccine

Get emergency medical help if you have signs of an allergic reaction: hives dizziness, weakness fast heartbeats difficult breathing swelling of your face, lips, tongue, or throat.

Keep track of all side effects you have. If you need a booster dose, you will need to tell the vaccination provider if the previous shot caused any side effects.

You should not receive a booster vaccine if you had a life-threatening allergic reaction after the first shot.

Becoming infected with meningococcal disease and developing meningitis is much more dangerous to your health than receiving this vaccine. Any vaccine may cause side effects but the risk of serious side effects is low.

You may feel faint after receiving this vaccine. Some people have had seizure like reactions after receiving this vaccine. Your doctor may want you to remain under observation during the first 15 minutes after the injection.

  • severe weakness or unusual feeling in your arms and legs
  • high fever or

Common side effects may include:

  • nausea, vomiting, diarrhea
  • low fever, not feeling well or
  • fussiness, irritability.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report vaccine side effects to the US Department of Health and Human Services at 1 800 822 7967.

Who Should Get The Meningococcal Vaccines

All children ages 11 through 12 years should receive meningococcal vaccine followed by a booster dose at age 16 years. Vaccination is also recommended for all adolescents ages 13 through 18 years who did not receive a dose at age 11-12 years.

Individuals ages 2 months and older who have certain conditions that weaken their immune system should receive meningococcal vaccine, including teens who are HIV positive. These persons should also receive booster shots every three to five years depending on their age. Talk to your health care provider if your preteen or teen has a condition that makes it harder for their body to fight off infection.

The MenB vaccine may also be given at age 16 years along with the MenACWY booster dose. MenB vaccine is also recommended for children age 10 years and older with certain high-risk conditions. The number of doses needed depends on the product used and if your child has a high-risk condition. Talk to your health care provider about this additional vaccine.

ACIP Updates Recommendations for Meningococcal Vaccination

Because the vaccines do not protect against all causes of meningitis, it is still possible that someone could receive the vaccine and still get meningitis from a different strain not protected by the vaccine. But the risk of contracting meningococcal meningitis is significantly lower after the vaccine.

: The chapter has been updated to align with the National Advisory Committee on Immunization Statement : The Use of Bivalent Factor H Binding Protein Meningococcal Serogroup B Vaccine for the Prevention of Meningococcal B Disease.

Updates include:

MenB-fHBP vaccine may be considered as an option for use in individuals 10 years of age and older in situations when a serogroup B meningococcal vaccine should be offered:

  • during serogroup B meningococcal disease outbreaks or with the emergence of hyperendemic Neisseria meningitidis strains that are predicted to be susceptible to the vaccine
  • for individuals who are close contacts with a case of invasive meningococcal disease caused by serogroup B Neisseria meningitidis
  • for individuals with underlying medical conditions that would put them at higher risk of meningococcal disease than the general population or
  • for individuals at higher risk of exposure to serogroup B meningococcal isolates than the general population.
  • MenB-fHBP vaccine may be considered as an option for individuals 1025 years of age who are not at higher risk of meningococcal disease than the general population, but who wish to reduce their risk of invasive serogroup B meningococcal disease.

    How Many Meningococcal Conjugate Vaccines Do You Need

    Meningococcal conjugate vaccine is usually given only once to adults and children 2 years and older. You may need a booster dose if you have a high risk of meningococcal infection and it has been at least 4 years since you last received this vaccine. Younger children will need to receive 2 to 4 doses.

    Symptoms And Causative Agent

    Neisseria meningitidis bacteria, also called meningococcus , are an important cause of bacterial meningitis and sepsis in the United States. Meningococci can also cause pneumonia, otitis media , arthritis, and other infections, although these are less common. Collectively, the different illnesses caused by N. meningitidis are referred to as meningococcal disease.

    Meningococcal meningitis symptoms include fever, headache, confusion and stiff neck, which may also be accompanied by nausea, vomiting, and sensitivity to light. Meningococcal bacteremia symptoms include sudden fever onset and rash. Other forms of meningococcal disease have symptoms related to the organ affected: otitis media has ear pain arthritis has joint pain and swelling.

    Invasive meningococcal disease can be fatal survivors may have permanent injury, including brain damage, hearing loss, or loss of a limb.

    What Are The Options For Meningococcal Vaccine

    Meningococcal vaccine explained – Dr Peter Richmond

    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.

    What Should I Discuss With My Healthcare Provider Before Receiving This Vaccine

    You may not be able to receive this vaccine if you’ve ever had an allergic reaction to a meningococcal, diphtheria, or tetanus vaccine.

    This vaccine may need to be postponed or not given at all if you have:

    • a severe illness with a fever or any type of infection
    • a weak immune system caused by disease or by using certain medicine
    • a history of Guillain-Barré syndrome or
    • a history of premature birth.

    You can still receive a vaccine if you’ve a minor cold.

    Your doctor should determine whether you need this vaccine during pregnancy or while breastfeeding.

    Effectiveness Of The Menacwy Vaccine

    The type of meningococcal vaccine that most young adults get is generally called the MenACWY vaccine, which protects against four strains of the Neisseria meningitidis bacteria.

    Since the CDC recommended vaccination for adolescents in 2005, cases of meningococcal disease fell by 90%. Similar declines werent seen in groups that didnt have this vaccine recommendation.

    Other studies also noted a large drop in meningococcal disease since the vaccine was introduced. One 2020 paper in JAMA Pediatrics analyzed the national rates of meningococcal disease between 2000 and 2005 and compared it to 2011 to 2017 .

    The annual incidence rates of three strains of meningococcal disease were already dropping in the pre-vaccine period by about 14.6% among adolescents 16 to 22 years old. But that drop accelerated after vaccine introduction. Between 2011 and 2017, the incidence of meningitis due to these strains dropped by 35.6% per year.

    This suggests that MenACWY vaccination is related to the drop in meningococcal disease among adolescents, though vaccination alone cant explain this decline. But other studies have replicated these results in other populations.

    A study compared meningococcal disease cases and deaths in the Republic of Korea Armed Forces between 2008 and 2013 and 2013 to 2016 . Data showed the MenACWY vaccine is 88% effective in protecting against meningococcal disease.

    What Are The Possible Side Effects Of Meningococcal Vaccines

    Some of the most common side effects are swelling, redness, and pain at the site of the injection, along with headache, fever, or tiredness. Serious problems, such as allergic reactions, are rare.

    The meningococcal vaccines contain only a small piece of the germ, so it can’t cause meningococcal disease.

    Can The Meningococcal Vaccine Cause Meningococcal Disease

    Vaccine, Menomune (Meningococcal groups A,C,Y,W

    The short answer is no. There are actually four meningococcal vaccines licensed in the U.S. None of the vaccines contains live bacteria.

    The vaccines contain antigens — substances that trigger the body’s immune system and cause it to make antibodies. These antibodies then protect the body by attacking and killing the bacteria if it should invade your system.

    The first vaccine — meningococcal polysaccharide vaccine or MPSV4 — was approved in 1978. It’s made with the antigens contained in the outer polysaccharide or sugar capsule that surrounds the bacterium.

    The meningococcal conjugate vaccine or MCV4 was approved in 2005. It uses antigens taken from the polysaccharide capsule and then bound to a separate protein that targets the body’s immune cells. This makes it easier for the body’s immune system to see and recognize the antigens.

    One type of MCV4, Menveo, is licensed for use in people ages 2 to 55. Another version, Menactra, is approved for those 9 months to 55 years old. MPSV4 is the only vaccine licensed for use in people over 55 as well as people 2 to 55. Both vaccines protect against four types of meningococcal disease.

    Are Students In College At Risk For Meningococcal Disease

    In the 1990s, college freshmen living in residence halls were identified as being at increased risk for meningococcal disease. Meningococcal disease and outbreaks in young adults were primarily due to serogroup C. However, following many years of routine vaccination of young people with quadrivalent meningococcal conjugate vaccine , serogroup B is now the primary cause of meningococcal disease and outbreaks in young adults. Among the approximately 9 million students aged 18-21 years enrolled in college, there are an average of 20 cases and 2-4 outbreaks due to serogroup B reported annually.

    Although incidence of serogroup B meningococcal disease in college students is low, college students aged 18-21 years are at increased risk compared to non-college students. The close contact in college residence halls, combined with certain behaviors , may put college students at increased risk.

    Is there a vaccine against meningococcal disease?

    Yes, there are 2 different meningococcal vaccines.

    What Are The Symptoms Of Meningococcal Disease

    Signs and symptoms of meningococcal disease include sudden onset of fever, stiff neck, headache, nausea, vomiting, sensitivity to light and/or mental confusion. A rash may also be present. Changes in behavior such as confusion, sleepiness, and unresponsiveness are important symptoms of illness. Anyone who has these symptoms should be seen by a healthcare provider immediately. In fatal cases, death can occur in as little as a few hours, even with appropriate medical treatment. Less common presentations include pneumonia and arthritis.

    How Is Meningococcal Disease Spread And Who Is Most At Risk

    Meningococcal disease is not as contagious as other illnesses, such as a cold or the flu. But it is spread by contact with infected respiratory and throat secretions. That can happen with coughing, kissing, or sneezing.

    Because the risk increases with close or prolonged contact with an infected person, family members in the same household and caregivers are at an increased risk. For the same reason, so are college students who live in dormitories.

    Guidance On Reporting Adverse Events Following Immunization

    90 second animation Meningococcal ACWY vaccine

    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.

    The vaccine is recommended, but not provided free, for the following people:

    • Laboratory workers routinely exposed to meningococcal bacteria
    • Military personnel
    • Those living or travelling in a high risk area for meningococcal disease

    For information on high risk travel areas contact a travel clinic.

    The vaccine is usually given as 1 dose. Some people may need additional doses of the vaccine. Speak with your health care provider to find out if you need more doses and when you should get them.

    People who are not eligible for the free vaccine but want to be protected against meningococcal A, C, Y and W strains of the disease can purchase the vaccine at most pharmacies and travel clinics.

    It is important to keep a record of all immunizations received.

    How Long Is The Meningococcal Conjugate Vaccine Good For

    Those at increased risk need regular booster doses. For children under the age of 7 years, administer a booster dose 3 years after completion of the primary series. For children 7 years old or older, administer a booster dose 5 years after completion of the primary series and every 5 years thereafter.

    Your booster schedule may be different. Follow the guidelines provided by your doctor or local health department.

    Be sure to receive all recommended doses of this vaccine or you may not be fully protected against disease.

    How Common Is Meningococcal Disease

    Meningococcal meningitis vaccine

    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.
