Immunisation of Children: A Lifesaving Choice

By Dr. Priya Sammani

It was a sunny Tuesday morning, and I had just started my clinic hours when a young mother, Emma, walked in with her four-year-old daughter, Sophie. Sophie clung tightly to her mom’s leg, looking shy but curious. Emma had a worried expression on her face.

“Dr. Priya,” she began, “Sophie is due for her vaccines, but honestly, I’m nervous. I’ve been hearing so much online—some people say vaccines are dangerous, others say they’re essential. I don’t want to make the wrong choice.”

I gestured for her to take a seat. “Emma, I understand your concerns. It’s completely normal to feel this way, especially with all the information out there. Let’s talk about it, step by step.”

Why Immunisation is So Important

I started by explaining the basics to Emma. “Vaccines are like giving Sophie an invisible suit of armor. They protect her from diseases that used to cause severe illness or even death in children.”

Emma looked thoughtful, so I continued. “When we give a vaccine, we’re teaching Sophie’s immune system how to recognize and fight a disease. It’s like showing her body a ‘wanted poster’ of the germ, so if the real thing ever shows up, her body knows how to fight it off.”

She nodded but asked, “But aren’t these diseases rare now? Why does she need protection?”

“That’s a great question,” I said. “These diseases are rare because of vaccines. For example, polio was once one of the most feared diseases worldwide. Thanks to vaccines, it’s almost eradicated. But if we stop vaccinating, these diseases can come back.”

Diseases Vaccines Protect Against

To make things clearer, I listed the diseases vaccines protect against. “Here’s what Sophie is being protected from,” I said, jotting it down for her.

DiseaseCauseWhy Vaccination Matters
DiphtheriaBacteriaCauses a thick membrane in the throat, blocking airways. Vaccination has made it almost extinct in many countries.
Whooping CoughBacteriaSevere coughing fits that make it hard for babies to breathe. Vaccines prevent life-threatening cases.
TetanusBacteriaCauses painful muscle stiffness (lockjaw). Spread through wounds. Rare due to vaccines.
PolioVirusCan cause paralysis or lifelong disability. Vaccines have almost eradicated it worldwide.
MeaslesVirusExtremely contagious; can cause brain swelling (encephalitis) and death. Prevented by the MMR vaccine.
MumpsVirusCauses swollen glands and, in some cases, brain infections or infertility. Part of the MMR vaccine.
RubellaVirusCan cause birth defects if contracted during pregnancy. Vaccination protects future mothers.
ChickenpoxVirusCauses itchy rashes and fever, but severe cases can lead to pneumonia. Vaccine prevents complications.
PneumococcusBacteriaCauses severe respiratory infections like pneumonia. Vaccines save thousands of lives annually.
Hepatitis BVirusCan cause liver disease later in life. Vaccination starts at birth to ensure lifelong protection.
RotavirusVirusThe most common cause of severe diarrhea in babies and young children. Vaccines prevent dehydration and complications.

Emma studied the table carefully. “I didn’t realize there were so many diseases these vaccines protect against,” she said softly.

A Real-Life Story: Why Vaccines Matter

Just then, another patient, Olivia, walked in with her six-year-old son, Ethan. Olivia overheard our conversation and chimed in. “Dr. Priya, can I share what happened with Ethan?”

“Of course,” I said, knowing her story would resonate with Emma.

Olivia took a deep breath. “When Ethan was just three months old, he caught whooping cough. He was too young to finish all his vaccines at that point, and he got it from another child at a daycare. He coughed so much he couldn’t breathe, and we had to rush him to the hospital. It was the scariest week of my life.”

Emma looked horrified. “Did he recover?”

“Yes,” Olivia said, smiling. “But it was a close call. That experience taught me how important vaccines are—not just for my kids but for everyone around them.”

How Vaccines Protect the Community

“That’s a great point, Olivia,” I said. Turning to Emma, I added, “Vaccines don’t just protect Sophie. They protect the whole community, especially babies like Ethan who are too young to be fully vaccinated.”

Emma raised an eyebrow. “How does that work?”

“It’s called herd immunity,” I explained. “When most people in a community are vaccinated, it’s harder for diseases to spread. This protects vulnerable people like newborns, pregnant women, or those with weak immune systems.”

Common Concerns About Vaccines

Emma still seemed a little unsure. “But what about side effects? Are vaccines really safe?” she asked.

“Vaccines are among the safest medical interventions we have,” I reassured her. “Most side effects are mild, like a sore arm or a low fever. These are signs that Sophie’s immune system is working. Serious side effects are extremely rare.”

“What if she’s unwell on the day of her vaccine?” Emma asked.

“If she has a mild cold, it’s fine to go ahead,” I said. “But if she has a fever or seems very unwell, it’s better to reschedule.”

What to Expect After Vaccination

I noticed Sophie looking up at me curiously. “Sophie, do you know what happens when you get a vaccine?” I asked with a smile.

She shook her head. I turned back to Emma. “After Sophie gets her shot, she might feel a bit cranky or have a slight fever. This is normal and goes away quickly. You can give her paracetamol if needed. Just keep her hydrated and let her rest.”

Emma smiled, visibly more at ease. “That doesn’t sound too bad.”

Realistic Tips for Parents

Before Emma left, I shared some practical tips:

  • Stick to the schedule: Vaccines work best when given on time. Delays can leave your child unprotected.
  • Keep a record: Use a vaccination booklet or app to track Sophie’s shots.
  • Comfort your child: Bring her favorite toy or snack to the appointment to keep her calm.
  • Ask questions: If you’re ever unsure, talk to your doctor.

Key Takeaways About Immunisation

I summarized the conversation for Emma so she could leave with a clear understanding:

  • Vaccines are essential for protecting children from serious diseases.
  • Side effects are mild and temporary, while the benefits are lifelong.
  • Sticking to the schedule ensures full immunity.
  • Vaccines protect not just your child but the whole community.

FAQs About Vaccination

1. Are vaccines safe for all children?
Yes, vaccines are rigorously tested for safety. Talk to your doctor if your child has specific medical conditions.

2. What if my child misses a dose?
It’s okay. Your doctor can help you create a catch-up schedule.

3. Can vaccines cause the diseases they’re meant to prevent?
No. Vaccines use inactivated or weakened germs, so they can’t cause the illness.

4. Why are multiple doses needed?
Some vaccines need boosters to ensure long-term protection.

Final Thoughts

As Emma and Sophie left the clinic, I could see relief on Emma’s face. “Thank you, Dr. Priya,” she said. “I feel so much more confident now.”

Vaccines are one of the simplest yet most effective ways to protect children. If you’re a parent with questions, remember—it’s always better to ask. Understanding how vaccines work and why they’re necessary can make all the difference in keeping your child healthy and safe.
