Meningococcal vaccines in children

Meningococcal vaccines are vaccines to protect against serious infections caused by bacteria called meningococcus. Meningococcal bacteria can cause serious infections such as meningitis and septicemia, which can progress quickly and be fatal.

Meningococcal vaccines generally protect against 2 different types: MenACWY and MenB. The MenACWY vaccine protects against four strains of meningococcal bacteria, including types A, C, W, and Y. The MenB vaccine provides protection against type B of meningococcal bacteria.

Children are usually recommended to be vaccinated with the MenACWY vaccine at 11-12 years of age and the MenB vaccine. In some cases, earlier vaccination or additional doses may be needed, especially if children live in crowded environments or are traveling.

Meningococcal vaccines are generally safe and serious side effects are rare. The most common side effects may include mild fever, pain, and swelling. In some rare cases, vaccines can cause allergic reactions, but these cases are very rare.

Meningococcal vaccines help protect children from serious infections caused by meningococcal bacteria and can prevent serious health problems from occurring. However, vaccines do not completely eliminate the risk of meningococcal infection. Therefore, it is also important to take other measures such as improving children's handwashing habits, avoiding dirty surfaces and limiting contact with sick people.
