Immunization for infants provides some protection from a few serious diseases at a young age. As babies’ immune systems are quiet developing, it is essential to ensure that they are vaccinated at the right time.
Under the Universal Immunization Programme (UIP) every child is vaccinated based on the National Immunization Schedule in India. Vaccines administered at birth and infancy and further at certain ages.
Parents might hear the terms immunization and vaccination used interchangeably. But they can have different meanings. Knowing these terms and maintaining an up-to-date immunisation record can help you to manage your baby’s health care plan.
What Is Infant Immunization?
Infant immunization is the act of assisting an infant through vaccination and other immunizing measures in protecting him or her from certain infectious diseases.
Vaccines stimulate the immune system to learn how to fight against specific parts or organisms that cause a disease without actually triggering the disease itself.
The infant vaccination is part of the National Immunization Schedule in India. Vaccines may be given to babies and could include: BCG, Hepatitis B, Oral Polio Vaccine, Pentavalent vaccine, Fractional IPV, Rotavirus vaccine, Pneumococcal conjugate vaccine, depending on the age of the baby and which programme it’s part of.
Certain vaccines are suggested at certain ages or certain areas. Parents are therefore advised to stick to the current official timetable and following their child’s healthcare professional’s advice.
Immunization vs Vaccination
Immunization and vaccination are very similar, but aren’t the same.
Generally, vaccination involves getting a vaccine.
The term immunization is used more generally to describe the condition of being immune to a disease, typically achieved by vaccination.
| Term | Simple Meaning |
| Vaccination | Receiving a vaccine |
| Immunization | Developing protection against a disease |
| Vaccine | A biological preparation that helps train the immune system |
| Immunity | Protection developed by the body’s immune system |
Doctors and parents might interchangeably use the words, vaccination and immunization in their everyday health discussions.
The most critical thing parents need to know is what vaccines are recommended for the baby’s age and to follow this schedule.
Why Immunization Is Important During Infancy
Infant is an important window for protection against vaccine-preventable diseases. In some cases, infections may lead to severe infections in young children.
By sticking to the suggested schedule, babies can receive their vaccines as recommended by health officials.
Immunization for babies can help:
- Lower the threat of some disease-causing organisms.
- Develop immunity in childhood.
- Provide support for community level disease control.
- Contribute to the control of some vaccine-preventable infections.
- Support to protect babies who are more susceptible to certain infections.
- Getting babies vaccinated is just one step in maintaining good health.
- Good nutrition, hygiene, safe sleep, regular health checks and medical treatment are also key.
- Parents not to delay a recommended vaccine if their baby looks healthy. If in doubt, ask the health care provider if a vaccine is needed.
Understanding Infant Immunization Schedules
Infant immunization schedule is the recommended ages and intervals for immunizations.
Vaccines are prescribed in the National Immunization Schedule starting from birth and continuing throughout infancy and childhood in India.

Keeping Immunization Records
One of the most convenient ways to stay organized is to keep an up-to-date immunization record.
Parents should store a copy of the baby’s vaccination card or other official record in a safe place. Make sure to document vaccinations as soon as possible.
Useful information includes:
- Vaccine name
- Date of vaccination
- Dose number
- Healthcare facility
- Next scheduled dose
- Any directions from the health care provider
Simple Immunization Record
| Information | Example |
| Vaccine | Vaccine name |
| Date given | Day, month, year |
| Dose | First, second, third, etc. |
| Health facility | Clinic or health centre |
| Next visit | Recommended date |
| Notes | Relevant instructions |
India has also launched U-WIN, a digital platform to facilitate the documentation and monitoring of immunization services under the Universal Immunization Programme (UIP).
Even if you have your baby’s vaccination information electronically, it’s important to maintain physical copies as well. It can help if you have to see a new doctor or travel away from home or look for missing doses.
Preparing for Immunization Appointments
There is a little preparation that can make vaccination appointments easier.
Before the appointment:
- Look at your baby’s immunisation history.
- Double check the date and time of the appointment.
- Compile a list of questions.
- Let the health care provider know of any previous severe reactions.
- Talk about any relevant medical conditions or medicines.
- Carry the baby’s health and immunisation records.
- Follow the instructions of the health care provider following vaccination.
Your health care provider may give you information after vaccination about what reactions to expect and what to do if you are worried about reactions.
Some vaccines may have mild reactions, but parents should seek advice from a health care professional if they are concerned about their baby’s reaction or their baby develops a serious reaction.
