According to the CDC, there are two types of meningococcal vaccines available in the United States. The first is the meningococcal polysaccharide vaccine or Menomune. The second is the meningococcal conjugate vaccine, which is otherwise referred to as Menactra, Menveo, and MenHibrix. Both vaccines work to prevent four types of meningococcal disease, including two of the three types that are most common in the United States. There are other, less common types of meningitis that the vaccines are unable to protect against.
How Does the Meningitis Vaccine Work?
The meningitis vaccine is made up of parts of the meningococcal bacteria that cannot cause infection. When you receive the vaccine, your body creates antibodies to fight these harmless traces of the meningococcus bacteria. As a result, these antibodies will help protect you from developing an actual infection if you come into contact with someone who has meningitis.
Who Needs the Meningitis Vaccine?
The meningococcal vaccine is mostly recommended for adolescents since those aged 16 through 21 years old are at the highest risk for the disease. Because the vaccine is only effective for five years, all 11 to 12-year-olds should be vaccinated with Menactra or Menveo, and then the booster should be given at age 16. Most importantly, if you are about to start college and have not had a meningitis vaccination in more than five years, it is highly recommended to receive the booster dose. In fact, it is required before attending many colleges.
Aside from young adults, there are other people who might be at risk for developing meningitis. You should consider receiving the meningococcal vaccine if you:
- Live in a residence hall or dormitory, such as on a college campus.
- Are a military recruit.
- Have a damaged spleen or your spleen has been removed.
- Have persistent complement component deficiency, which is an immune system disorder.
- Are part of a laboratory personnel who is routinely exposed to meningococcal bacteria.
- Are traveling or residing in countries where the disease is common, such as parts of Africa.
- Have been exposed to meningitis during an outbreak.
What are the Risks Receiving a Meningitis Vaccine?
Like any medicine, vaccines have the possibility to cause serious problems. However, the risk of the meningococcal vaccine resulting in serious harm or death is very small. The most common side effects for adolescents are brief fainting spells or jerking, seizure-like movements. Sometimes this can cause falls and injuries. If you or a loved one feels faint, sitting or lying down for about 15 minutes after the vaccination can help prevent this from happening.
One other mild side effect that is experienced by about half of the people who get the meningococcal vaccination is redness, pain, or swelling at the site of the shot. Additionally, a small percentage of people who receive the vaccine develop a slight fever. If these problems occur, they will probably last for about one to two days.
A serious allergic reaction, which can result in severe health issues or even death, after the shot is very rare but not impossible, so be aware of any side effects that are consistent with an allergic reaction. These include hives, swelling of the face and throat, dizziness, weakness, and fast heartbeat. These kinds of symptoms would usually develop within a few minutes to an hour after receiving the shot.
