Childhood Vaccines: All You Need to Know


Why Should Your Children Get Vaccinated? 

Vaccines are important to keep your little one safe from infections as they grow up. When your baby is immunised, his body produces antibodies to fight off that disease. . Childhood immunisation also protects others who are around your child, and vice versa. This is a concept known as herd immunity. 

What is herd immunity? 

When a large number of a certain area or country is immune to a specific disease and is resistant to the causes of a certain virus or bacteria, it has no way to spread. 

The infection rates drop, and the disease slowly dies off. Herd immunity protects those at risk, such as babies and young children, whose immune systems are weak and can’t resist the disease on their own. 

How Do Vaccines Work?

Germs (viruses and bacteria) are all around us, externally, and in our own bodies. Getting vaccinated will stimulate your immune system to produce antibodies, exactly like it would if you were exposed to the disease. 

These antibodies then remain in our bloodstream, protecting our bodies against future infections from the same germs. This is also known as immunity. For example, if you get measles, your body may produce antibodies to fight off the virus, and those antibodies will remain in your body, making you immune to measles in the future. 

The Idea Behind Vaccines

Vaccines are made from the same viruses (or parts of them) that cause the disease. However, in vaccines, the viruses are altered in such a way that they cannot cause illnesses.

Our immune system, however, still reacts to the virus or bacteria in the same way, by creating the same antibodies that protect us and provide immunity to the diseases.

The main difference between getting vaccinated and not getting vaccinated is that your child doesn’t have to get sick in the first place, to be protected against the disease. 

Vaccines are usually introduced into our bodies via injection. While some vaccines give us immunity for life, others may require repeated booster shots to maintain immunity.

Will there be any side effects after my child’s vaccination?

As parents, you may be worried about the visit to the paediatrician when it is time for your child’s vaccination. It is definitely normal for your baby to cry a little after the injection, and your baby might feel a little sore on the injection site. There may also be slight redness and a small lump on the injection site, which should clear within a few days. 

In some cases, your baby might also develop a slight fever for a day or two after the injection. Most babies are fit for immunisation, but if you noticed that your baby is having a high fever, or had a serious reaction from previous vaccination, you need to consult your paediatrician for medical advice.

Child Vaccination In Singapore

Compulsory Vaccinations For Children In Singapore

Every child in Singapore is vaccinated according to the National Childhood Immunisation Schedule (NCIS), comprising childhood vaccinations recommended as the standard of care for protection against vaccine-preventable diseases.

In Singapore, vaccinations against measles and diphtheria are compulsory for children under the Infectious Diseases Act.

There are other vaccinations that are not compulsory but highly recommended by the Ministry of Health, based on recommendations from the Expert Committee on Immunisation (ECI), which takes into consideration elements such as local disease burden, vaccine safety, efficacy and cost-effectiveness of the vaccines: 

  • Hepatitis B
  • Mumps
  • Pertussis 
  • Pneumococcal
  • Polio
  • Rubella
  • Tetanus

Combination Vaccines

Today, vaccines are combined into a single injection. These 5-in-1 or 6-in-1 vaccines means fewer injections for children.

  • The 5-in-1 injection combines vaccines against Diphtheria/Pertussis/Tetanus (DPT), Polio and Haemophilus Influenzae type B (Hib) in 1 injection.
  • The 6-in-1 injection combines vaccines against Diphtheria/Pertussis/Tetanus (DPT), Polio, Haemophilus Influenzae type B (Hib) and Hepatitis B in 1 injection.  
  • The MMRV vaccine combines vaccines against four common childhood diseases, Measles, Mumps, Rubella and Varicella (also known as chickenpox).

Additional Vaccines Covered Under the NCIS

Currently, the NCIS covers vaccinations against 12 diseases – tuberculosis, hepatitis B, diphtheria, tetanus, pertussis, poliovirus, Haemophilus influenza type b, measles, mumps, rubella, pneumococcal disease and human papillomavirus. 

From 1 November 2020, the NCIS will also cover vaccinations against two more diseases, i.e. varicella (chickenpox) and influenza.
