Adverse reactions to meningococcal vaccines

Meningococcal meningitis is the abbreviation of epidemic cerebrospinal meningitis, which is commonly known as epidemic meningitis. Epidemic meningitis is highly contagious. It is a disease that seriously endangers patients. Many patients lose their lives due to delayed treatment due to lack of attention, and some patients are left disabled. The onset of meningococcal meningitis is mostly seen in children. It is more common in winter and spring, usually occurring from November to December before the previous year or from February to May of the following year.

In order to reduce the harm of meningococcal meningitis to patients, my country began to develop meningococcal vaccine in the 1960s, but it was not successful until the 1980s when the meningococcal vaccine was successfully used clinically. So far, the meningococcal vaccine has been widely used, and many people are concerned about the adverse reactions of the meningococcal vaccine.

After receiving the meningococcal vaccine, some people will experience mild reactions, such as redness, swelling, pain, and transient fever at the injection site, and rarely, swollen axillary lymph nodes. These reactions will generally disappear after 24 hours, so don't worry about them. Those with high fever can receive antipyretic and symptomatic treatment under the guidance of a doctor, and their condition will generally improve quickly. Some people with allergic constitutions may experience allergic reactions, such as rash, allergic purpura, etc., but severe allergic reactions rarely occur. If you have an allergic reaction, you should see a doctor immediately. Another thing that needs to be noted is that patients with a history of central nervous system diseases may experience epilepsy and convulsions after being injected with meningococcal vaccine.

Types and specifications of meningococcal vaccines

Group A meningococcal vaccine: After vaccination, this vaccine can produce humoral immune response in the body and is used to prevent epidemic meningitis caused by group A meningococci. Since the use of meningococcal vaccine, it has played a very important role in controlling and reducing the spread of meningococcal disease, and the epidemic has been basically controlled. Group A+C meningococcal vaccine: Group A+C meningococcal vaccine is generally used for children or adults over 2 years old. Group A+C meningococcal vaccine should not be used for children under 2 years old.

The meningococcal vaccine has been clinically tested to be safe and reliable. It can be used for both infants and adults. Children use group A meningococcal vaccine, and adults can be injected with group A+C meningococcal vaccine. The meningococcal vaccine has no major adverse reactions. We hope that the general public can use it with confidence without worrying about adverse reactions to the influenza vaccine.
