NeisVac-C is a vaccine, a type of medicine used to protect against infectious diseases. NeisVac-C is used to prevent invasive disease caused by bacteria called Neisseria meningitidis group C.
The Neisseria meningitidis bacteria can cause serious and sometimes life-threatening infections such as meningitis and septicaemia (blood poisoning). NeisVac-C will only protect against invasive disease caused by the meningococci group C bacteria. It will not protect against other groups of meningococci or other organisms that cause meningitis and blood poisoning.
When a person is given NeisVac-C, the immune system (the body's natural defence system) will produce its own protection (antibodies) against disease.
Your body usually takes several weeks after vaccination to develop protection against invasive meningococcal disease. Most people will produce enough antibodies to protect them against invasive meningococcal disease. However, as with all vaccines, 100% protection cannot be guaranteed.
NeisVac-C will not give you or your child meningococcal disease.
The chance of a severe reaction from NeisVac-C is very small, but the risks from not being vaccinated against invasive meningococcal disease may be very serious.
NeisVac-C is given to children from 8 weeks of age, adolescents and adults.
