Preventing illnesses is an essential aspect of healthcare, and vaccinations play a crucial role in achieving this goal. During the early stages of life, infants acquire a level of protection against infections from their mothers and through breastfeeding, as their natural immunity develops. However, this immunity starts to decline around the age of six months. Vaccinations step in by strengthening a child's immune system, training it to recognize and respond effectively to diseases.

By exposing the child's body to a weakened or inactivated form of a disease-causing agent, vaccinations prompt the production of antibodies, which provide defence against future infections. This process is vital in safeguarding children from serious and potentially life-threatening illnesses. In Singapore, the National Childhood Immunisation Programme (NCIP) has been implemented for numerous years and has significantly contributed to the overall health of the population.

Understanding Immunity and Vaccinations

The various organs, cells, and proteins comprise our immune system. Our bodies naturally have an "innate" immune system, and an "acquired" immune system develops as a result of vaccines, exposure to viruses, bacteria, and other disease-causing pathogens, or both.

Our bodies retain these antibodies so that the next time we are exposed to certain pathogens, we have the "armour" to defend ourselves against that particular disease.

By introducing vaccinations to our bodies, which introduce a "killed" or "weakened" version of the germ in a "safe" manner, we can create vaccine-induced immunity, a type of acquired immunity.

Our immune system consists of various organs, cells, and proteins that work together to protect our bodies. It comprises both the "innate" immune system, which we naturally possess, and the "acquired" immune system, which develops through vaccines, exposure to pathogens, or a combination of both.

When we encounter viruses, bacteria, or other disease-causing agents, our bodies develop antibodies that help us fight off those specific pathogens. These antibodies are retained by our immune system, providing us with a defence mechanism for future encounters with the same pathogens.

Vaccinations play a vital role in building this acquired immunity. They introduce a "weakened" form of the disease-causing germ into our bodies in a safe manner. This exposure triggers our immune system to produce a response, including the creation of antibodies, resulting in vaccine-induced immunity. This type of acquired immunity equips our bodies with the necessary armour to effectively defend against specific diseases when we come into contact with them again.

Importance of Childhood Vaccination

Childhood vaccination plays a critical role in safeguarding children against infectious diseases that can lead to severe complications and other serious issues. Vaccines stimulate the immune system to produce specific antibodies targeted at pathogens such as viruses and bacteria. When a vaccinated child comes into contact with the virus, their immune system can rapidly generate these antibodies, effectively fighting off the infection and preventing its spread.

In addition to providing individual protection, vaccinations also contribute to herd immunity. This means that when a significant portion of the population is vaccinated, the entire community is protected against the disease. This reduces the likelihood of the disease spreading to unvaccinated individuals or those who are unable to receive the vaccine due to medical reasons. By promoting childhood vaccination, we can not only protect our children but also create a safer environment for everyone.

Types of Vaccines Offered by NCIP

Below is a list of the 10 diseases that are vaccinated against by NCIP in Singapore:

● Tuberculosis

● Hepatitis B

● Diphtheria

● Pertussis (whooping cough)

● Tetanus

● Poliomyelitis (polio)

● Haemophilus influenza type b (Hib)

● Measles

● Mumps

● Rubella

The vaccinations offered in the NCIP can be given individually or in combination. Combination vaccinations are given in order to streamline the vaccination schedule and minimize the number of doses required.

Compulsory Vaccinations for Children

In Singapore, every child follows the National Childhood Immunisation Schedule (NCIS), which sets the standard for safeguarding against vaccine-preventable diseases. The NCIS ensures that all children receive the essential childhood vaccines recommended for their age group. Additionally, the Infectious Diseases Act in Singapore legally requires children to receive vaccinations for measles and diphtheria, further emphasizing the importance of immunization in protecting children's health and well-being.

Vaccination Schedule for Children

The National Childhood Immunisation Programme (NCIP) recommends a comprehensive vaccination schedule that starts at birth and continues until the child reaches 18 years of age. This schedule is carefully designed to ensure that vaccines are administered at appropriate intervals, maximizing their effectiveness in providing protection.

The NCIP's suggested vaccination schedule is listed below:

Side Effects of Vaccination

Like any medication, vaccines can have potential side effects, although they are generally minor. Common adverse effects include a sore, red, or swollen injection site, as well as mild fever and fussiness. Serious side effects are rare but can include allergic reactions, seizures, or high fever.

If parents have any concerns or questions regarding vaccines or if their child experiences any side effects after vaccination, it is recommended that they consult their child's healthcare professional. Healthcare professionals are well-equipped to address any concerns and provide guidance to ensure the well-being of the child.


Childhood vaccination is an important public health intervention that aids in protecting kids from serious and potentially fatal illnesses. If parents have any questions or concerns, they should contact their child's healthcare professional. Parents should make sure their children receive all prescribed vaccinations on time.
