Understanding the Child Immunization Schedule: A Parent's Guide

The child immunization schedule is a series of recommended vaccines designed to protect your child from serious and potentially life-threatening diseases. Understanding this schedule is crucial for ensuring your child's health and well-being. This guide will walk you through the basics, covering common vaccines, their timing, and what to expect.

Why is the Child Immunization Schedule Important?

Vaccines work by exposing your child's immune system to a weakened or inactive form of a disease-causing agent. This allows their body to develop antibodies, providing immunity without actually contracting the illness. Following the recommended schedule ensures your child receives protection at the optimal age, when they are most vulnerable to these diseases.
