Vaccination is one of the most effective ways to protect children from serious infectious diseases. By helping the body’s immune system recognize and fight harmful germs, vaccines have significantly reduced illnesses and deaths caused by diseases that were once common.
Health experts encourage parents to follow their country’s routine childhood immunisation schedule to ensure children receive protection at the recommended ages.
How Vaccines Work
Vaccines train the immune system to recognize specific viruses or bacteria without causing the disease itself. If a vaccinated child is later exposed to the infection, the body can respond more quickly, reducing the risk of severe illness.
Some vaccines require more than one dose to provide long-lasting protection.
Vaccines Commonly Given During Childhood
Although immunisation schedules vary by country, many routine childhood vaccination programmes include protection against the following diseases:
Tuberculosis (BCG)
The BCG vaccine helps protect children from severe forms of tuberculosis, particularly those affecting the brain and other organs.
Hepatitis B
The hepatitis B vaccine protects against a viral infection that affects the liver and can lead to chronic liver disease later in life.
Polio
Polio is a highly infectious disease that can cause permanent paralysis. Vaccination has greatly reduced the number of cases worldwide.
Diphtheria, Tetanus and Pertussis (Whooping Cough)
These vaccines protect against three serious bacterial diseases that can cause breathing difficulties, muscle spasms, and life-threatening complications in children.
Haemophilus influenzae type b (Hib)
The Hib vaccine helps prevent infections that can cause meningitis, pneumonia, and other serious illnesses in young children.
Pneumococcal Disease
Pneumococcal vaccines protect against bacteria that can cause pneumonia, bloodstream infections, and meningitis.
Rotavirus
Rotavirus vaccination helps prevent severe diarrhoea and dehydration in infants and young children.
Measles, Mumps and Rubella (MMR)
The MMR vaccine protects against three contagious viral diseases that can lead to serious complications, including hearing loss, brain inflammation, and birth defects if rubella occurs during pregnancy.
Why Childhood Vaccination Is Important
Vaccines offer several important benefits, including:
- Protecting children from serious diseases.
- Reducing the risk of disability and death.
- Preventing outbreaks within communities.
- Protecting babies and individuals with weakened immune systems through community immunity.
- Reducing healthcare costs associated with preventable illnesses.
Are Vaccines Safe?
Vaccines undergo extensive testing before approval and are continuously monitored for safety after they are introduced.
Like any medicine, vaccines may cause mild side effects such as soreness at the injection site, slight fever, or temporary fussiness. Serious side effects are rare, and the benefits of vaccination generally far outweigh the risks.
Parents who have concerns should discuss them with a qualified healthcare professional.
What If a Child Misses a Vaccine?
If a child misses a scheduled vaccination, parents should contact their healthcare provider as soon as possible. In many cases, the child can receive a catch-up vaccination without restarting the entire schedule.
Keeping accurate immunisation records helps ensure children receive all recommended doses.
The Bottom Line
Vaccination is one of the safest and most effective ways to protect children from preventable diseases. Following the recommended immunisation schedule helps safeguard not only individual children but also families and communities by reducing the spread of infectious diseases.
