Vaccination is one of the most effective ways to protect children from serious infectious diseases. It helps strengthen your baby’s immune system, reduces the risk of life-threatening illnesses, and also protects the community through herd immunity.
In this guide, Dr. Gouda Ankula Prasad, Consultant Neonatologist and pediatrician in Pune at Momstory, answers common questions about vaccines, their safety, side effects, and the recommended immunization schedule.
What is Vaccination?
Vaccination is the process of introducing a harmless form of a virus or bacteria (or a part of it) into the body to stimulate the immune system.
Once vaccinated, the body produces antibodies that help recognize and fight the infection if the child is exposed to it in the future.
Vaccines are one of the safest and most cost-effective methods of preventing infectious diseases.
Why is Vaccination Important?
According to health data, a significant number of deaths in children under five years of age are caused by vaccine-preventable diseases.
Timely vaccination helps:
- Protect babies from serious infections
- Reduce the risk of hospitalization
- Prevent disease outbreaks
- Build herd immunity within the community
- Improve long-term child health
Every baby vaccine in Pune should be administered according to the recommended immunization schedule to ensure maximum protection.
Types of Vaccines
Vaccines are broadly classified into two categories.
1. Live Vaccines
These contain weakened forms of the virus or bacteria.
Examples include:
- BCG
- Oral Polio Vaccine (OPV)
- Rotavirus Vaccine
- Measles Vaccine
- Chickenpox (Varicella) Vaccine
- Live Hepatitis A Vaccine
2. Inactivated (Killed) Vaccines
These contain killed organisms or specific components of bacteria or viruses.
Examples include:
- Diphtheria
- Pertussis
- Tetanus (DPT)
- Pneumococcal Vaccine
- Meningococcal Vaccine
- Hepatitis A (Inactivated)
- Japanese Encephalitis Vaccine
Are Vaccines Safe?
Yes. Vaccines undergo extensive testing before they are approved and are considered very safe.
While most children experience only mild side effects, serious reactions are extremely rare.
Common Side Effects of Vaccination
Mild side effects usually resolve within a day or two and may include:
- Pain at the injection site
- Mild swelling or redness
- Low-grade fever
- Fussiness or irritability
- Temporary discomfort while moving the vaccinated limb
These reactions are a normal sign that the immune system is responding.
Rare but Serious Side Effects
Although uncommon, parents should seek immediate medical attention if their child experiences:
- Difficulty breathing
- Severe allergic reaction (Anaphylaxis)
- Persistent high fever
- Seizures associated with fever
- Extreme drowsiness or reduced activity
Such reactions are very rare, but prompt evaluation is essential.
Government Immunization Programme
India’s Universal Immunization Programme (UIP), launched in 1985, initially covered six diseases. Today, it protects children against nearly twelve major vaccine-preventable illnesses, including:
- BCG
- Polio
- Hepatitis B
- Diphtheria
- Pertussis
- Tetanus
- Pneumococcal disease
- Rotavirus
- Measles
- Rubella
- Japanese Encephalitis (in selected regions)
- HPV vaccine (introduced in some states)
Vaccines Recommended by the Indian Academy of Pediatrics (IAP)
In addition to government vaccines, the IAP recommends certain optional vaccines for better protection.
These include:
- MMR (Measles, Mumps, Rubella)
- Chickenpox (Varicella)
- Influenza (Flu)
- Typhoid
- Meningococcal Vaccine
Your child specialist in Pune can help determine which optional vaccines are appropriate based on your child’s age and health.
Why Do Babies Need Multiple Vaccine Doses?
Newborn babies have an immature immune system.
Additionally, maternal antibodies present after birth may temporarily interfere with the baby’s own immune response.
This is why many vaccines require:
- Multiple primary doses
- Booster doses later in childhood
Boosters help maintain long-term immunity as protection naturally decreases over time.
Painful vs Painless Vaccines
Many parents ask about the difference between painful and painless vaccines.
Whole-cell Pertussis Vaccine (Painful)
- Slightly stronger immune response
- Higher chance of fever, swelling, and pain after vaccination
Acellular Pertussis Vaccine (Painless)
- Fewer side effects
- Better tolerated by babies
- Slightly more expensive and generally available in private healthcare settings
Both vaccines are effective. Your pediatrician can guide you on the most suitable option for your child.
Government vs Private Vaccines
Government vaccination programmes provide highly effective vaccines free of cost.
Private vaccination schedules may include:
- Painless vaccine options
- Additional vaccines not yet included in the government programme
- Combination vaccines for greater convenience
Parents can choose the most appropriate schedule after discussing it with their doctor.
Do Vaccines Provide 100% Protection?
No vaccine offers 100% protection.
However, vaccines significantly reduce:
- The risk of infection
- Disease severity
- Hospitalization
- Serious complications
Some diseases, such as influenza, require annual vaccination because the virus changes over time.
Success Stories of Vaccination
Vaccination has transformed public health across the world.
Major achievements include:
- Eradication of Smallpox
- Elimination of Polio in India
- Elimination of Maternal and Neonatal Tetanus in India
These milestones highlight the life-saving impact of immunization.
When Should You Consult a Pediatrician?
Consult your doctor if:
- Your child misses a scheduled vaccine
- You have questions about optional vaccines
- Your child develops severe reactions after vaccination
- You are unsure about the recommended immunization schedule
Timely guidance from an experienced pediatrician ensures your child receives complete protection against preventable diseases.
Final Thoughts
Vaccination is one of the greatest achievements in modern medicine. Following the recommended immunization schedule protects not only your baby but also your family and community.
If you have questions about vaccines, their schedule, or possible side effects, consult an experienced pediatric healthcare professional for personalized guidance.
