Childhood Vaccination Schedule Guide

Vaccination is one of the most effective public health interventions ever developed. This guide explains the routine schedule and what each vaccine protects against.

Standard schedule
8 weeks to teenage years
Most vaccines
Given in combination
Herd immunity threshold
~95% for measles
Safety monitoring
Extensive ongoing surveillance

Vaccine Safety

Vaccines undergo extensive testing before approval and continued safety monitoring afterward. Common side effects (mild fever, soreness at injection site) are expected immune responses and far outweigh the risks of the diseases prevented. Serious adverse events are rare and are actively monitored by health authorities worldwide.
Catch-Up Vaccination Is Always AvailableIf your child has missed vaccinations for any reason, it's never too late to catch up — contact your GP practice to arrange a catch-up schedule at any age.
Do vaccines overload a baby's immune system?
No — babies' immune systems handle thousands of antigens daily from their environment. The number of antigens in the entire childhood vaccine schedule is a tiny fraction of what a baby's immune system manages routinely.
Can my child have vaccines if they have a mild cold?
Yes, generally — mild illness without fever is not a reason to delay vaccination. If your child has a high fever or is more significantly unwell, your GP or nurse may advise postponing.
Are combination vaccines safe?
Yes — combination vaccines (like the 6-in-1) have been extensively studied and are safe and effective, and reduce the number of injections needed.
