What are the adverse reactions after meningococcal vaccination?

It is said that some people will experience some adverse physical reactions after receiving the meningococcal vaccine. Therefore, if we find that our bodies have adverse reactions or slight changes after receiving the vaccine, we must go to the hospital for medical treatment in time. Otherwise, the consequences will be very serious. We need to understand this. What are the adverse reactions after meningococcal vaccination? Let’s take a look.

Meningococcal meningitis refers to "epidemic cerebrospinal meningitis". This disease is a type of purulent meningitis caused by infection with meningococci or transmitted through the respiratory tract. In order to prevent such diseases from occurring or spreading in winter and spring, vaccination is necessary. However, adverse reactions after meningococcal vaccination sometimes occur. Symptoms include high fever, severe headache, projectile vomiting, small bleeding spots on the skin, stiff neck, coma, convulsions, shock, etc., and the mortality rate is relatively high. In China, children account for more than 90% of all meningococcal cases. Vaccination against meningococcal meningitis is the most direct and effective way to prevent meningococcal meningitis.

General reaction. After vaccination with the meningococcal vaccine, the reaction is mild, and there are generally no serious local or systemic reactions. After vaccination, some children may experience local redness and mild pain for 1-2 days; systemic reactions include low fever, with 1%-4% of recipients experiencing a fever exceeding 38.5°C; allergic reactions may occasionally occur. Most recipients experience symptoms 10-24 hours after vaccination and generally recover on their own within 1-2 days. Symptomatic treatment may be provided if necessary. Patients with a history of central nervous system diseases may experience epilepsy and convulsions after injection of meningococcal vaccine. It is necessary to avoid repeated injections of meningococcal vaccine within three years. If injected, symptoms such as fever and allergies may occur.

Abnormal reaction to vaccination. Abnormal reactions to vaccination refer to adverse drug reactions caused by qualified vaccines during or after standardized vaccination, which cause damage to the recipient's body tissues, organs, and functions, and are not the fault of any of the parties involved.

There are many adverse reactions after vaccination with meningococcal vaccine, and if there are adverse reactions to this type of vaccination with meningococcal vaccine, people will experience local pain in their bodies, and sometimes, it will be accompanied by swelling, redness or fever. We need to understand these situations and go to the hospital for medical treatment in time.
