IMMUNIZATION IN CHILDREN: A CLEAR MESSAGE TO PARENTS AND THE PUBLIC

As a paediatrician, one of my most important responsibilities is to guide parents in protecting their children’s health. Among all preventive measures available today, immunization remains one of the safest, most effective, and most impactful interventions in modern medicine. Childhood vaccines have saved millions of lives worldwide and continue to protect children from serious illness, disability, and death.

What is immunization and why is it essential?
Immunization helps a child’s immune system recognize and fight dangerous infections by safely exposing it to weakened or inactive parts of germs. This allows the body to build protection without causing the disease itself. Before vaccines were widely used, diseases such as measles, polio, diphtheria, whooping cough, tetanus, tuberculosis, and hepatitis were common and often fatal. Today, many of these diseases are rare—but they still exist and can return if vaccination rates fall.

Children are most vulnerable to infections in the early years of life. The recommended immunization schedule is carefully designed to provide protection at the right age, before children are exposed to these diseases. Delaying or missing vaccines leaves children unprotected and increases the risk of outbreaks in the community.

Important facts for parents to know
All vaccines recommended for children undergo extensive testing for safety and effectiveness before approval. After approval, they are continuously monitored worldwide. Most children experience only mild side effects, such as pain or swelling at the injection site, mild fever, or temporary irritability. These reactions are usually short-lived and resolve on their own.

Serious side effects are extremely rare. In contrast, vaccine-preventable diseases can cause pneumonia, brain infections, paralysis, hearing loss, long-term disability, or death. The benefits of vaccination far outweigh the risks.

Common myths and the facts behind them

Myth 1: Vaccines cause autism.

Fact: Large scientific studies involving millions of children have clearly shown that vaccines do not cause autism. This myth arose from a study that was later found to be false and withdrawn. There is no credible evidence linking vaccines to autism.

Myth 2: Natural immunity is better than vaccine-induced immunity.

Fact: Natural infection may lead to immunity, but at a very high cost. Diseases like measles or polio can result in severe complications or death. Vaccines provide strong protection without exposing children to these dangers.

Myth 3: Too many vaccines overload a child’s immune system.
Fact: A child’s immune system handles thousands of germs every day. The number of antigens in vaccines is very small in comparison and well within the immune system’s capacity.

Myth 4: Vaccines are no longer needed because these diseases are rare.

Fact: These diseases are rare because vaccination coverage has been high. When immunization rates decline, outbreaks occur, as seen with measles and diphtheria in recent years.

Myth 5: A child should not be vaccinated if they are sick.
Fact: Minor illnesses such as a mild cough, cold, low-grade fever, loose motions, or mild diarrhea are not contraindications to vaccination. Children with these mild conditions can be safely vaccinated. Only moderate or severe illness may require temporary postponement, as advised by a healthcare professional. Unnecessary delay can leave a child unprotected.

Myth 6: If a child misses a vaccine, they cannot be vaccinated later.
Fact: If any vaccine dose is missed, the child can and should be vaccinated. Parents should contact their paediatrician as soon as possible for rescheduling the vaccine at the earliest appropriate time. There is no need to restart the entire immunization schedule. Catch-up vaccination schedules are safe, effective, and widely used.

Immunization protects the whole community
Vaccination is not only an individual decision—it is a shared responsibility. Some children, such as newborns or those with weakened immune systems, cannot be vaccinated and depend on others for protection. High vaccination coverage creates herd immunity, reducing the spread of disease and protecting the most vulnerable members of society.

In conclusion
As a paediatrician, I strongly encourage all parents and caregivers to follow the recommended immunization schedule and seek information from trusted healthcare professionals. Questions and concerns are natural, and open discussion is always welcome. However, fear and misinformation should never stand in the way of protecting a child’s health.

Immunization is one of the greatest achievements of modern medicine—safe, effective, and essential. By vaccinating children on time and catching up on missed doses, we protect not only their future, but the health and safety of our entire community.
