Vaccination is the process of introducing a vaccine into the body to help the immune system build resistance against specific diseases. Rather than waiting for illness to strike, vaccination for kids prepares the body in advance — equipping it with the antibodies it needs to fight off infections before they take hold.
A vaccine contains the disease-causing microorganism in a weakened or inactive form. It does not cause the disease — but it does trigger the immune system to recognise and respond to it. So if the actual infection enters the body in the future, the immune system is already prepared to tackle it effectively.
For children, whose immune systems are still developing, this protection is not just advisable. It is essential.
