For example, the measles vaccine is usually not given until the child is at least one year old. It may not work so well if given earlier than the recommended age.

Both doctors and parents like them because it enables a person to receive several vaccines in one go.\nThe recommended national immunisation schedule is as follows for healthy newborns starting immunisation in Singapore. For overseas-born children, please refer to individual vaccine details for minimum intervals for catch-up doses or unusual schedules.\nNational Childhood Immunisation Schedule - Singapore\n(Reference: \nNational Immunisation Registry\n)\nImmunisation records for children born on or after 1 January 1996 are retrievable at the\nNational Immunisation Registry website\n.\nFor parents who would like to obtain additional protection for your children, you may want to opt for the combination and additional optional vaccines, available at selected clinics and hospitals. An alternative schedule with combination or additional vaccines might look like this:\nSuggested Age\nWith Combination\/Additional Vaccines.\nAt birth\nBCG\nHep B1 – 1st dose\n2 Months\n6-in-1 – 1st dose \nRotavirus – 1st dose\n4 Months\n5-in-1 – 2nd dose\nRotavirus – 2nd dose\nPCV – 1st dose\n6 Months\n6-in-1 – 3rd dose \nPCV – 2nd dose\n12 Months\nPCV – booster\nMMR – 1st dose\n± VZV – 1st dose (can be given as MMRV*)\n± Hep A – 1st dose\n15 - 18 Months\n5-in-1 – booster\nMMR – 2nd dose\n± VZV – 2nd dose (can be given as MMRV)\n18 - 21 Months\n± Hep A – 2nd dose (six months from first dose)\n9 years onwards\nHPV: 2 doses or 3 doses depending on the age\n10 - 11 Years\nTdAP\nOPV\/IPV second booster\nImmunisation Agent:\nVZV: Varicella Zoster\nHep A: Hepatitis A vaccine\nHPV: Human papilloma virus\n*Please discuss with your doctor on the benefits and concerns regarding MMRV.\nPlease enquire at your clinic or hospital for more information.\nVaccination Checklist ?\nSometimes a child should not be given a particular vaccine or it should be given at a later date. Therefore tell your doctor if your child:\nIs sick today\nHas any allergies e.g. egg allergy\nHas developed a severe reaction after being vaccinated previously\nHas ever had a seizure or any kind of disorder of the nervous system\nDoes not seem to be developing normally\nHas a weakened immune system e.g. on steroids or has a cancer\nHas any household contacts with a weakened immune system e.g. on steroids or has a cancer\nHas received any blood transfusion (e.g. immunoglobulins) recently\nIt will be necessary to bring along the child’s past immunisation record.\nIs Vaccination Safe?\nVaccination is generally a very safe procedure. Like other medications, they can occasionally cause reactions. Most of these are mild, such as a sore arm or mild fever. Serious reactions are rare.\nVaccination with BCG produces a small raised bump 2 weeks later. The raised bump ulcerates within weeks to months later, and heals slowly with scarring. For MMR (measles, mumps and rubella) vaccine, fever and\/or mild rash may occurs after 5 days from the time of vaccination. One can also develop a mild chicken pox-like rash after being vaccinated against chicken pox.\nIf there are any serious reactions, see your doctor as soon as possible. Your doctor can discuss the risks before vaccinating your child. Remember that getting the disease is generally much more serious than the side-effects of the vaccine.\nWill Vaccines Always Work?\nVaccinations work most of the time, about 90-99% of the children will develop immunity to them. However, occasionally a child may not respond to a vaccine. This is another reason why all children need to be vaccinated. A child who has not responded to a particular vaccine could be infected by a child who is not vaccinated, but not by one who is immune.","attrs_markdown":"SingHealth Institutions will NEVER ask you to transfer money over a call.

Combination Vaccines Combination vaccines such as measles, mumps, rubella (MMR) are a few vaccines given together in a single shot. Both doctors and parents like them because it enables a person to receive several vaccines in one go. The recommended national immunisation schedule is as follows for healthy newborns starting immunisation in Singapore. For overseas-born children, please refer to individual vaccine details for minimum intervals for catch-up doses or unusual schedules. **National Childhood Immunisation Schedule - Singapore  (Reference: *[*National Immunisation Registry*](https:\/\/www.nir.hpb.gov.sg\/nirp\/eservices\/immunisationSchedule)*)![National Childhood Immunisation Schedule - Singapore](https:\/\/www.singhealth.com.sg\/content\/dam\/singhealth-web\/common\/imported-assets\/assets\/conditions-treatments\/images\/kkh\/vaccinations-national-childhood-immunisation-schedule-kkh.jpg)** Immunisation records for children born on or after 1 January 1996 are retrievable at the  [National Immunisation Registry website](https:\/\/www.nir.hpb.gov.sg\/nirp\/eservices\/login). For parents who would like to obtain additional protection for your children, you may want to opt for the combination and additional optional vaccines, available at selected clinics and hospitals.

Please enquire at your clinic or hospital for more information. Vaccination Checklist ? Sometimes a child should not be given a particular vaccine or it should be given at a later date. Therefore tell your doctor if your child: Is sick today Has any allergies e.g. egg allergy Has developed a severe reaction after being vaccinated previously Has ever had a seizure or any kind of disorder of the nervous system Does not seem to be developing normally Has a weakened immune system e.g. on steroids or has a cancer Has any household contacts with a weakened immune system e.g. on steroids or has a cancer Has received any blood transfusion (e.g. immunoglobulins) recently It will be necessary to bring along the child’s past immunisation record. Is Vaccination Safe? Vaccination is generally a very safe procedure. Like other medications, they can occasionally cause reactions. Most of these are mild, such as a sore arm or mild fever. Serious reactions are rare. Vaccination with BCG produces a small raised bump 2 weeks later. The raised bump ulcerates within weeks to months later, and heals slowly with scarring. For MMR (measles, mumps and rubella) vaccine, fever and\/or mild rash may occurs after 5 days from the time of vaccination. One can also develop a mild chicken pox-like rash after being vaccinated against chicken pox. If there are any serious reactions, see your doctor as soon as possible. Your doctor can discuss the risks before vaccinating your child. Remember that getting the disease is generally much more serious than the side-effects of the vaccine. Will Vaccines Always Work? Vaccinations work most of the time, about 90-99% of the children will develop immunity to them. However, occasionally a child may not respond to a vaccine. This is another reason why all children need to be vaccinated. A child who has not responded to a particular vaccine could be infected by a child who is not vaccinated, but not by one who is immune.","meta_canonical":null}

For example, the measles vaccine is usually not given until the child is at least one year old. It may not work so well if given earlier than the recommended age. Some vaccines such as \DTaP / IPV / Hib need to be given as a series of injections to work best. 1. \Diphtheria/Pertussis/Tetanus (DTaP) 2. Inactivated Polio (IPV) 3. Haemophilus Influenzae type B (HiB) ### What Happens If My Child Misses A Shot? If your child did not get her shots on time, it is not too late. If your child has gotten some of her shots and then fallen behind schedule, she can catch up without having to start the whole schedule again. ### Combination Vaccines Combination vaccines such as measles, mumps, rubella (MMR) are a few vaccines given together in a single shot. Both doctors and parents like them because it enables a person to receive several vaccines in one go. The recommended national immunisation schedule is as follows for healthy newborns starting immunisation in Singapore. For overseas-born children, please refer to individual vaccine details for minimum intervals for catch-up doses or unusual schedules. *National Childhood Immunisation Schedule - Singapore (Reference: [National Immunisation Registry](https://www.nir.hpb.gov.sg/nirp/eservices/immunisationSchedule)) ![National Childhood Immunisation Schedule - Singapore](https://www.singhealth.com.sg/content/dam/singhealth-web/common/imported-assets/assets/conditions-treatments/images/kkh/vaccinations-national-childhood-immunisation-schedule-kkh.jpg)* Immunisation records for children born on or after 1 January 1996 are retrievable at the [National Immunisation Registry website](https://www.nir.hpb.gov.sg/nirp/eservices/login). For parents who would like to obtain additional protection for your children, you may want to opt for the combination and additional optional vaccines, available at selected clinics and hospitals. An alternative schedule with combination or additional vaccines might look like this: \| Suggested Age \| With Combination/Additional Vaccines. \| \|---\|---\| \| At birth \| BCG Hep B1 – 1st dose \| \| 2 Months \| 6-in-1 – 1st dose Rotavirus – 1st dose \| \| 4 Months \| 5-in-1 – 2nd dose Rotavirus – 2nd dose PCV – 1st dose \| \| 6 Months \| 6-in-1 – 3rd dose PCV – 2nd dose \| \| 12 Months \| PCV – booster MMR – 1st dose ± VZV – 1st dose (can be given as MMRV\) ± Hep A – 1st dose \| \| 15 - 18 Months \| 5-in-1 – booster MMR – 2nd dose ± VZV – 2nd dose (can be given as MMRV) \| \| 18 - 21 Months \| ± Hep A – 2nd dose (six months from first dose) \| \| 9 years onwards \| HPV: 2 doses or 3 doses depending on the age \| \| 10 - 11 Years \| TdAP OPV/IPV second booster \| Immunisation Agent: VZV: Varicella Zoster Hep A: Hepatitis A vaccine HPV: Human papilloma virus \Please discuss with your doctor on the benefits and concerns regarding MMRV. Please enquire at your clinic or hospital for more information. ## Vaccination Checklist ? Sometimes a child should not be given a particular vaccine or it should be given at a later date. Therefore tell your doctor if your child: - Is sick today - Has any allergies e.g. egg allergy - Has developed a severe reaction after being vaccinated previously - Has ever had a seizure or any kind of disorder of the nervous system - Does not seem to be developing normally - Has a weakened immune system e.g. on steroids or has a cancer - Has any household contacts with a weakened immune system e.g. on steroids or has a cancer - Has received any blood transfusion (e.g. immunoglobulins) recently It will be necessary to bring along the child’s past immunisation record. ## Is Vaccination Safe? Vaccination is generally a very safe procedure. Like other medications, they can occasionally cause reactions. Most of these are mild, such as a sore arm or mild fever. Serious reactions are rare. Vaccination with BCG produces a small raised bump 2 weeks later. The raised bump ulcerates within weeks to months later, and heals slowly with scarring. For MMR (measles, mumps and rubella) vaccine, fever and/or mild rash may occurs after 5 days from the time of vaccination. One can also develop a mild chicken pox-like rash after being vaccinated against chicken pox. If there are any serious reactions, see your doctor as soon as possible. Your doctor can discuss the risks before vaccinating your child. Remember that getting the disease is generally much more serious than the side-effects of the vaccine. ## Will Vaccines Always Work? Vaccinations work most of the time, about 90-99% of the children will develop immunity to them. However, occasionally a child may not respond to a vaccine. This is another reason why all children need to be vaccinated. A child who has not responded to a particular vaccine could be infected by a child who is not vaccinated, but not by one who is immune. ##### Contributed by ##### [Infectious Disease Service](https://www.kkh.com.sg/our-specialties/infectious-disease.html), [KK Women's and Children's Hospital](https://www.kkh.com.sg/) The information provided is not intended as medical advice.

Combination Vaccines Combination vaccines such as measles, mumps, rubella (MMR) are a few vaccines given together in a single shot. Both doctors and parents like them because it enables a person to receive several vaccines in one go. The recommended national immunisation schedule is as follows for healthy newborns starting immunisation in Singapore. For overseas-born children, please refer to individual vaccine details for minimum intervals for catch-up doses or unusual schedules. *National Childhood Immunisation Schedule - Singapore (Reference: [National Immunisation Registry](https://www.nir.hpb.gov.sg/nirp/eservices/immunisationSchedule))![National Childhood Immunisation Schedule - Singapore](https://www.singhealth.com.sg/content/dam/singhealth-web/common/imported-assets/assets/conditions-treatments/images/kkh/vaccinations-national-childhood-immunisation-schedule-kkh.jpg)* Immunisation records for children born on or after 1 January 1996 are retrievable at the [National Immunisation Registry website](https://www.nir.hpb.gov.sg/nirp/eservices/login). For parents who would like to obtain additional protection for your children, you may want to opt for the combination and additional optional vaccines, available at selected clinics and hospitals. An alternative schedule with combination or additional vaccines might look like this: Suggested Age With Combination/Additional Vaccines. At birth BCG Hep B1 – 1st dose 2 Months 6-in-1 – 1st dose Rotavirus – 1st dose 4 Months 5-in-1 – 2nd dose Rotavirus – 2nd dose PCV – 1st dose 6 Months 6-in-1 – 3rd dose PCV – 2nd dose 12 Months PCV – booster MMR – 1st dose ± VZV – 1st dose (can be given as MMRV\) ± Hep A – 1st dose 15 - 18 Months 5-in-1 – booster MMR – 2nd dose ± VZV – 2nd dose (can be given as MMRV) 18 - 21 Months ± Hep A – 2nd dose (six months from first dose) 9 years onwards HPV: 2 doses or 3 doses depending on the age 10 - 11 Years TdAP OPV/IPV second booster Immunisation Agent: VZV: Varicella Zoster Hep A: Hepatitis A vaccine HPV: Human papilloma virus \Please discuss with your doctor on the benefits and concerns regarding MMRV. Please enquire at your clinic or hospital for more information. Vaccination Checklist ? Sometimes a child should not be given a particular vaccine or it should be given at a later date. Therefore tell your doctor if your child: Is sick today Has any allergies e.g. egg allergy Has developed a severe reaction after being vaccinated previously Has ever had a seizure or any kind of disorder of the nervous system Does not seem to be developing normally Has a weakened immune system e.g. on steroids or has a cancer Has any household contacts with a weakened immune system e.g. on steroids or has a cancer Has received any blood transfusion (e.g. immunoglobulins) recently It will be necessary to bring along the child’s past immunisation record. Is Vaccination Safe? Vaccination is generally a very safe procedure. Like other medications, they can occasionally cause reactions. Most of these are mild, such as a sore arm or mild fever. Serious reactions are rare. Vaccination with BCG produces a small raised bump 2 weeks later. The raised bump ulcerates within weeks to months later, and heals slowly with scarring. For MMR (measles, mumps and rubella) vaccine, fever and/or mild rash may occurs after 5 days from the time of vaccination. One can also develop a mild chicken pox-like rash after being vaccinated against chicken pox. If there are any serious reactions, see your doctor as soon as possible. Your doctor can discuss the risks before vaccinating your child. Remember that getting the disease is generally much more serious than the side-effects of the vaccine. Will Vaccines Always Work? Vaccinations work most of the time, about 90-99% of the children will develop immunity to them. However, occasionally a child may not respond to a vaccine. This is another reason why all children need to be vaccinated. A child who has not responded to a particular vaccine could be infected by a child who is not vaccinated, but not by one who is immune.
