Parents often strive hard to keep up with their baby’s vaccination schedule, but vaccination may be missed for several reasons: the appointment may have been forgotten, the baby may have been unwell, the family may have been travelling, or the vaccination centre may have been inaccessible. Remember that missing a routine vaccine does not mean you failed as a parent.
The good news is that in most situations, a missed vaccine can be administered via catch-up immunisation. The World Health Organisation (WHO) recommends catch-up immunisation for children who have missed doses and stresses that they should be vaccinated at the earliest opportunity.
Remember not to panic or wait for the next routine appointment. Ask your child’s paediatrician to review your baby’s vaccination record and develop a catch-up plan[1].
Routine childhood vaccines are administered at specific ages to protect babies from serious infections. A missed vaccine means your baby did not receive a recommended dose at the specific age or time mentioned in the immunisation schedule. A routine vaccine may be missed because the immunisation appointment was forgotten, the baby was travelling, the baby was sick at the time of appointment, the vaccine was unavailable, the family moved to another city or country, the parents found it challenging to access healthcare services, or the parents were unaware that another vaccine dose was due.
Missing a scheduled date does not necessarily mean that the vaccine can no longer be given. Catch-up vaccination involves administering eligible vaccine doses to people who have missed or delayed them according to the national immunisation schedule.
Usually, it is not required. Parents should know that a delayed vaccination series does not need to be restarted merely because there has been a gap. An interruption in the immunisation course does not require repetition of the previous doses. For example, if your baby received the first two doses of a vaccine but missed the last dose, the paediatrician will determine when the next dose can be given rather than restarting the entire series.
However, developing a catch-up plan depends on your child’s age, the type of vaccine missed, the number of doses already received, dates of previous doses, minimum gap between doses, the respective country’s immunisation schedule, and the child’s medical history.
Never try to recreate the schedule yourself. Always show the vaccination record to your paediatrician to create a catch-up plan.
In general, the sooner the child is eligible to receive a missed vaccine, the sooner they can be protected. Timely immunisation protects babies against vaccine-preventable diseases. A catch-up immunisation plan should be created without delay so that children can be vaccinated at the earliest opportunity.
Call your child’s paediatrician, inform them about the missed vaccine, and ask them to check the vaccination record to determine when the catch-up dose can be given.
Even if your baby is significantly behind their immunisation schedule, you can still give catch-up doses. Catch-up immunisation should be an important part of routine immunisation programs[2] rather than organising special immunisation campaigns, as babies who miss the dose can be identified and vaccinated at the earliest.
The catch-up schedule may differ from the original schedule because your baby’s age has changed. Some vaccines have age limits or different recommendations depending on when vaccination is started. Thus, do not assume that you are “too late” to vaccinate your child and immunisation is no longer useful.

Do not be overwhelmed if your baby has missed multiple vaccines. Consult your paediatrician with your baby’s vaccination record. They can determine which doses have been given and which ones are still needed. In some cases, multiple vaccines can be given in one visit. This can help the baby catch up without unnecessary delays. The paediatrician will consider the baby’s age, previous doses, and the minimum intervals between vaccines when preparing a catch-up schedule.
Don’t panic. If you have lost the immunisation card, contact the paediatrician who may have a record of the vaccines your baby has received at their clinic. If the previous vaccination record cannot be obtained, the paediatrician will try to reconstruct the records (e.g., using hospital discharge documents, previous immunisation receipts, images of vaccination records) in accordance with the applicable national guidelines.
Do not guess which vaccines your baby received. After the records are reconstructed, keep the updated vaccination information in a safe place and save a digital photograph as a backup.
Parents sometimes postpone vaccination because their baby is ill (e.g., a cold, mild cough, etc.). Consult your paediatrician to determine whether your baby can get the vaccine or should it be postponed to the next scheduled date. Postponing immunisation can cause unnecessary gaps in protection
Some babies develop temporary reactions following immunisation, such as soreness at the injection site, mild fever, irritability, or sleepiness. Although these are short-lived reactions, follow the paediatrician’s advice.
If the baby had a reaction in the previous dose, it does not mean that future doses should be skipped. However, if your baby had a severe or unusual reaction after a previous vaccine, inform the paediatrician before another dose is given. The paediatrician will decide whether the vaccine should be given or whether any additional precautions are required.
In many vaccination programs, babies can receive multiple recommended vaccines during the same visit. This can be particularly useful for children who are catching up after missed doses. It can reduce the number of visits needed and help bring the child closer to being fully protected. However, this depends on the child’s age, previous vaccination history, and national guidelines. Do not skip a vaccine because several injections are scheduled for the same appointment unless the paediatrician advises otherwise.
Vaccination schedules vary between countries and can also get updated as national recommendations change. In India, the Government of India’s National Immunisation Schedule includes vaccines given at different stages, beginning at birth and continuing through infancy and childhood.
However, the schedule varies depending on factors such as previous vaccines, medical conditions, and whether vaccines were received through the national program or privately.
Parents should therefore use the current schedule recommended by their child’s paediatrician or the relevant health authority, rather than relying on an old vaccination chart found online.
Moving between countries can make vaccination records confusing because immunisation schedules are not identical everywhere. Take complete vaccination records and consult the paediatrician in your new country. The doctor can compare previous vaccines with the local schedule and determine which doses are still required.
Do not assume that a vaccine given in another country “does not count.” Your paediatrician can review the vaccine name, dose, date, and other information to determine how it fits into the local schedule.
Vaccines used for catch-up vaccination are part of established immunisation programs. However, whether a particular vaccine is appropriate depends on the child’s age, health, and vaccination history. Tell the paediatrician if your baby has had a serious allergic reaction to a previous vaccine, has a significant medical condition, takes medicines that affect the immune system, has an immune-system disorder, or has recently been seriously ill. This will help the paediatrician decide whether the vaccine should be given, delayed, or modified.
The main reason is protection. Vaccines protect children against diseases that can cause serious illness, disability, or death. Delaying vaccination leaves a child without the intended protection for longer. Timely vaccination is important to protect babies against vaccine-preventable diseases.
Measles is a good example. It is highly contagious, and gaps in vaccination coverage cause outbreaks. Measles cases have increased substantially in recent years, highlighting the consequences of immunity gaps. Catching up not only protects your child but also helps protect the vulnerable population who may not be able to receive certain vaccines.
The process is simple.
Missing a routine vaccine is generally not an emergency by itself. However, seek prompt medical care if your baby is currently unwell for example, if the baby has difficulty breathing, is unusually difficult to wake, is not feeding adequately, has signs of dehydration, has a seizure, or appears seriously ill.
If your baby has potentially been exposed to a vaccine-preventable infection, contact your paediatrician promptly. Depending on the disease and circumstances, additional preventive measures may sometimes be available.
If you missed your baby’s routine vaccine, don’t panic and don’t give up on the vaccination schedule. Most missed vaccine doses can be addressed through an appropriate catch-up plan, and interrupted vaccination courses generally do not need to be restarted from the beginning.
The next step is to contact your baby’s paediatrician, show the vaccination record, and ask for a catch-up schedule. Vaccination schedules are designed to protect at the appropriate ages[6], so getting back on track as soon as possible is important. Parents should not feel guilty about a missed appointment. What matters most is recognising the gap and taking the next step.
Remember, a missed vaccine is a reason to catch up, not a reason to give up.
