Vaccination

Missed a vaccine date? Your child does not need to start again

If a vaccine was missed on its due date, the doses already given still count. The missed dose is given at the next visit and the schedule simply continues from there.

Travel, a family function, a busy month or a child who was unwell: many children miss a vaccine on the exact date written on their card. Parents often worry that the whole course must now be repeated. In almost all cases, it does not.

The doses already given still count

Protection builds dose by dose. When a dose is late, the earlier doses are not wasted. The doctor continues the course from where it stopped; it is not restarted. Once the course is completed, a longer gap between doses does not lower the final protection.

Until the missed dose is given, though, your child is not yet fully protected against that disease. So the next convenient visit is better than waiting for a "perfect" date.

One exception to keep in mind: the oral rotavirus vaccine has an upper age limit for its doses. If a rotavirus dose has been missed, do not wait long to show the card to your child's doctor.

What you can do

  1. Find your child's vaccination card, or the vaccination record in your phone.
  2. Look for the vaccines that were due but have no date written against them.
  3. Take the card with you to your child's doctor. The doctor will plan which doses to give now and when the next ones fall due.
  4. Ask for the next due date to be written on the card before you leave.

More than one vaccine on the same day is usually fine

Catching up often means two or more vaccines at one visit. Almost all vaccines can safely be given on the same day, and doing so protects your child sooner. A few combinations need a gap; your doctor will tell you if that applies.

A mild cold is usually not a reason to wait

A runny nose, mild cough, mild loose motions or a low fever do not usually mean the vaccine has to be postponed. If your child is moderately or severely unwell, the doctor may advise waiting until your child is better.

Missed a dose at birth?

Some vaccines are meant to be given soon after birth. If the birth dose of hepatitis B vaccine was missed, the Indian Academy of Pediatrics advises giving it at the first contact with a health facility.

Keep the record safe. Take a photo of every page of the vaccination card after each visit, and set a phone reminder for the next due date.
