Your child's vaccination date is coming up, but then the questions start.

What if the child has a mild cold? What happens if a vaccine was missed? Are all vaccines really necessary? And should you postpone the appointment because your child is slightly unwell?

These are common concerns. We hear them from parents regularly, and the answer is rarely as simple as “yes” or “no.”

Vaccination decisions should be based on the child's age, health, vaccination history, and the specific vaccine involved—not on advice from a neighbour or a social media post.

Why Are Childhood Vaccines Important?

Vaccines prepare the immune system to recognise certain infections before the child encounters them.

They help reduce the risk of serious diseases and also contribute to protecting communities, particularly people who cannot receive certain vaccines or who are more vulnerable to infections.

The important point is that vaccines work best when children receive recommended doses at the appropriate ages.

When Should Your Child Get Vaccinated?

The vaccination schedule begins from birth and continues throughout childhood.

Depending on the vaccine and local recommendations, children may need:

  • Vaccines shortly after birth

  • Infant vaccinations

  • Multiple doses of certain vaccines

  • Booster doses later in childhood

  • Vaccines for specific risks or age groups

The exact schedule can vary based on national recommendations, the child's medical history, previous doses, and other factors.

That is why keeping a written or digital vaccination record is so useful.

What If a Vaccine Was Missed?

This is one of the most common concerns we hear.

Parents sometimes think that missing one dose means the entire vaccination schedule must be restarted.

In many situations, that is not necessary. A pediatrician can review the child's previous vaccination record and advise on a catch-up plan.

The important thing is not to ignore the missed dose simply because the original date has passed.

Can a Child Be Vaccinated With a Mild Cold?

A mild runny nose or minor cold does not automatically mean vaccination must be postponed.

However, whether vaccination should proceed depends on the child's overall condition and the specific circumstances.

If your child has a significant illness, high fever, or another medical concern, discuss it with the pediatrician before vaccination.

Rather than making the decision based on a blanket rule, consider the child's actual health on the day.

What Side Effects Should Parents Expect?

Most vaccine reactions are mild and temporary.

A child may experience soreness where the injection was given, mild fever, tiredness, or irritability.

Parents should know what reactions are expected and which symptoms require medical attention. Your pediatrician can explain this based on the specific vaccine your child receives.

The goal is not to pretend that vaccines have no side effects. Honest counselling means discussing both benefits and possible reactions.

A Real-World Example

A common situation is a child who has missed one or more vaccines because the family moved, travelled, or simply lost track of dates.

The parents may feel embarrassed and delay the appointment further.

We tell our clients not to think that way.

Once the available vaccination records are reviewed, the pediatrician can determine which doses have already been given and what remains due. A clear catch-up plan can turn a confusing situation into a manageable one.

Missing a vaccine is a problem to solve—not a reason to avoid the doctor.

The Contrarian Insight: Don't Turn Vaccination Into a Competition

Parents sometimes compare vaccination schedules between children.

“My neighbour's child received this vaccine earlier.”

“My relative says her child got a different number of doses.”

This comparison can create unnecessary confusion because vaccination needs can differ depending on age, health conditions, previous doses, local recommendations, and other factors.

The right question is not “What did another child receive?”

It is “What does my child's vaccination record show, and what is recommended next?”

A 2024 Vaccination Statistic

According to WHO and UNICEF estimates released in 2025, global coverage for the third dose of the diphtheria, tetanus, and pertussis-containing vaccine reached 85% in 2024.

However, approximately 20 million infants missed at least one DTP-containing vaccine dose during the year.

The numbers show both progress and the continuing importance of keeping children on schedule.

How to Prepare for a Vaccination Appointment

Before visiting the pediatrician, keep your child's vaccination record available.

Tell the doctor about:

  • Previous vaccine reactions

  • Current medicines

  • Allergies or known medical conditions

  • Recent illness

  • Previous vaccination dates

  • Any vaccines received elsewhere

You can also write down your questions before the appointment.

Don't hesitate to ask which vaccine is being given, why it is needed, what reactions are expected, and when the next dose is due.

Frequently Asked Questions

1. What happens if my child misses a vaccine?

Don't panic and don't simply abandon the schedule. Bring the child's vaccination record to a pediatrician. The doctor can review previous doses and recommend an appropriate catch-up plan.

2. Can my child get vaccinated if they have a cold?

A mild illness does not always require vaccination to be postponed. However, a child with significant illness or other concerning symptoms should be assessed by a healthcare professional before vaccination.

3. Are vaccines safe for children?

Vaccines are carefully evaluated and monitored for safety. Like medicines, they can cause side effects, most of which are mild and temporary. Your pediatrician can explain the benefits and possible reactions for each vaccine.

Keep the Vaccination Record Simple and Up to Date

You don't need to memorise every vaccine your child has received.
