Childhood vaccination schedule across Arab countries: what your child needs and when

What vaccines does your child need, and when?

The core immunisation programme recommended by the World Health Organisation covers at least ten diseases in the first two years of life. These include polio, measles, tetanus, diphtheria, pertussis (whooping cough), hepatitis B, Haemophilus influenzae type b (Hib), and others. The schedule starts at birth with the first hepatitis B dose and oral polio vaccine, and builds systematically through the first year and a half.

The primary doses at two, three and four months complete what is known as the pentavalent vaccine series, covering five diseases in one injection. Booster doses then follow at around 18 months and again before school entry. The MMR vaccine protecting against measles, rubella and mumps is given at 12 to 15 months, with a second dose before school age.

Understanding why timing matters helps you take it seriously. The schedule is designed around the periods when a young immune system is most vulnerable and when maternal antibody protection inherited at birth is fading. A child fully vaccinated on schedule builds layered protection. A child with gaps remains genuinely at risk during those gaps, not just theoretically.

How do schedules differ across Arab countries?

The core differences between countries are mostly about timing and optional additions, not about the fundamental vaccines. Saudi Arabia and the UAE include pneumococcal (PCV) and rotavirus vaccines in their national schedules, covering causes of pneumonia, meningitis, and severe infant diarrhoea that are not yet on all regional government schedules. These vaccines are available privately in most Arab countries but at a cost.

Egypt added Hib to its national pentavalent schedule in 2014 and has progressively strengthened its programme through the Ministry of Health. Jordan's schedule closely mirrors WHO recommendations with the addition of rotavirus vaccine in recent years. Lebanon's core vaccines align with regional neighbours though availability varies by health sector.

In Syria, years of conflict caused severe disruption to what was once one of the strongest immunisation programmes in the region. A 2025 review published in Frontiers in Public Health confirmed that armed conflict sharply reduces vaccination coverage and leaves communities without adequate immunity for years. This is why catch-up immunisation campaigns after ceasefires are treated as a health emergency priority.

What happens if your child has missed doses?

The reassuring truth is that you do not need to start over. Health systems and paediatricians use what are called catch-up schedules, which ensure that any child, at any age, can complete their protection against diseases they missed. A 2026 systematic review in Vaccine examining catch-up immunisation among displaced and refugee populations found that organised interventions can achieve good coverage even in very difficult circumstances.

The practical guidance is straightforward. Keep your child's vaccination record somewhere safe, whether a physical card or a photo on your phone. If the record is lost, tell the doctor what you remember and which country the vaccines were given in. When there is genuine uncertainty, repeating some doses is safe, because repetition does no harm but gaps can.

Children displaced from Syria, Iraq, Yemen and Sudan are the most likely to have immunisation gaps. If you are responsible for a child who has come from a conflict zone, ask the nearest health centre to assess their vaccination status as a priority before school enrolment. Many host countries offer this assessment free of charge.

Why measles vaccination is the most urgent priority

Measles is the most contagious of all vaccine-preventable diseases. It can travel through the air of a room and remain infectious for up to two hours after an infected person has left. In a community where fewer than 95% of people are immunised, a single measles case can infect between 12 and 18 others. To put that in perspective, the early Covid-19 virus infected around 2 to 3 people per case. No other common infectious disease comes close to measles in its capacity to tear through an under-immunised population.

The MMR vaccine protects against three diseases simultaneously: measles, rubella (which causes serious birth defects, particularly heart and brain abnormalities, when a pregnant woman is infected in her first trimester), and mumps. The second dose before school age raises measles protection from around 93% after the first dose to over 97%. That small numerical difference translates into a meaningful reduction in community vulnerability when populations are large.

In recent years the Arab region has seen measles outbreaks in areas where conflict or vaccine hesitancy reduced coverage below the critical threshold. A 2021 systematic review on pertussis in the Middle East by Macina and Evans highlighted how reduction in booster coverage creates vulnerability in older children and adults, a pattern that applies equally to measles. The danger of measles is not only the rash: the virus suppresses the immune system for weeks afterwards, opening the door to pneumonia, encephalitis and death, particularly in malnourished children. If your child has not had both MMR doses, addressing that is the single most important thing you can do for their health.

One point worth knowing for mothers: if you were vaccinated against measles yourself, you pass some protection to your baby through the placenta and through breast milk. That protection fades after a few months, which is why the first MMR dose at 12 months is timed for when maternal antibody levels have dropped enough not to interfere with the vaccine's effect. Do not be tempted to give the vaccine earlier thinking it will provide better protection.

Oral versus injectable polio vaccine: what is the difference?

Polio vaccine comes in two forms: oral (OPV), given as drops into the mouth, and injectable (IPV), given as an injection. The oral vaccine is cheaper and easier to distribute, and spreads gut immunity through communities in a helpful way. In very rare cases, however, OPV can cause vaccine-derived polio in unimmunised contacts. IPV is completely safe and highly effective but does not produce the same community gut immunity.

Current WHO guidance recommends at least one IPV dose alongside multiple OPV doses. Most Arab countries now follow this approach. If your child received only OPV doses, that still represents good protection and there is no urgent need to repeat with IPV if the series was complete.

The global goal is the total eradication of wild poliovirus. The Arab region is close to this goal, but immunisation gaps created by conflict keep the virus viable wherever community immunity is incomplete. Every unimmunised child is an opportunity for the virus to return.

What additional vaccines are available privately?

Beyond the government core schedule, paediatricians recommend additional vaccines that may not be offered free at government centres. The pneumococcal vaccine (PCV) protects against bacterial meningitis, pneumonia and ear infections caused by Streptococcus pneumoniae. It is included in government schedules in Saudi Arabia and the UAE but is available privately across the region.

The rotavirus vaccine protects against the leading viral cause of severe infant diarrhoea and is given as drops in the mouth at two and three months. Chickenpox (varicella) vaccine reduces complications particularly in children with chronic illness. Meningococcal vaccine is recommended in Saudi Arabia before Hajj and for students in boarding settings.

If you are not sure whether your child has had any of these additional vaccines, raise it with their paediatrician. The decision depends on your child's age, health status, country of residence and what is affordable. The priority is always to complete the government core schedule first before adding extras.

Common vaccine concerns that worry parents

Many parents ask whether a vaccine can cause the disease it is meant to prevent. For the vast majority of vaccines, the answer is no. Inactivated vaccines and subunit vaccines contain killed organisms or fragments that are biologically incapable of causing infection. Live attenuated vaccines such as MMR contain weakened viruses and may cause very mild symptoms in five to fifteen percent of children one to two weeks after the jab, because the weakened virus triggers a small immune response. This is normal and expected, and it is not the disease itself. A faint rash or low-grade temperature in the week after MMR is a sign that the immune system is working.

On the question of autism and vaccines, the answer from the science is definitive: no link exists between MMR or any other vaccine and autism spectrum disorder. The 1998 paper that claimed such a link was retracted in full, and its author lost his medical licence after investigation found data manipulation. Denmark, the UK and Japan subsequently conducted studies covering millions of children and found no connection. Autism typically becomes noticeable at the age when the early childhood vaccines are being given, and that timing coincidence is not causation.

A practical question families often raise is whether a sick child can be vaccinated. If your child has a mild illness such as a runny nose or mild cough with no fever, vaccination is usually safe to proceed. If they have a temperature above 38.5 degrees Celsius or a clearly debilitating acute illness, postponing until recovery is the right call. Do not delay vaccination for minor symptoms, because every day of delay is a day of genuine risk, especially for the youngest children.

Some families ask about reducing injection pain in infants. Breastfeeding during or immediately after the vaccination has been shown to reduce crying and distress noticeably. Gentle massage of the injection site after the needle is removed helps. At home, a cloth-wrapped ice pack on a red or swollen spot provides comfort. Age-appropriate paracetamol at the weight-correct dose can be given if the child is uncomfortable in the hours after vaccination.

When should you go to emergency after a vaccine?

Most reactions after vaccination are mild and temporary: soreness at the injection site, redness, a low-grade temperature, or a fretful night. These do not need emergency attention and settle within a day or two. A weight-appropriate dose of paracetamol can help with discomfort and mild fever.

Severe allergic reactions (anaphylaxis) are extremely rare but happen within 15 minutes of vaccination. This is why you are asked to wait in the clinic or health centre for a quarter of an hour after the jab before leaving. If you notice swelling of the face or lips, difficulty breathing, or a rapidly spreading rash after you have left, go to an emergency department immediately.

Inconsolable crying for more than three hours, neck stiffness, a seizure, or any clear deterioration in your child's level of consciousness after vaccination all require prompt medical assessment. These are rare events, but they are serious ones and should not be managed with a wait-and-see approach at home.
