Patient's question:
Now it is one year and one month. My baby received the A+C meningococcal vaccine at nine months. Recently, I looked up relevant information and found that children under two years old are prohibited from receiving the A+C vaccine. What harm could this cause?Doctor's answer:
Meningococcal meningitis is a respiratory infectious disease caused by Neisseria meningitidis infection. Its clinical manifestations include high fever, headache, projectile vomiting, and neck stiffness. It can also cause sepsis, purpuric congestion, and skin purpura. Meningitis can lead to brain damage, leaving behind sequelae such as hearing loss or deafness, intellectual disability, etc. The mortality rate is 5% to 10%. The incidence of meningococcal meningitis is high during winter and spring. Generally, cases begin to increase from November to December, with the peak period from February to May of the following year. This disease is a highly prevalent and high-risk infectious disease that severely harms children's health.
