Vaccination is one of the simplest and most effective ways to protect children from serious infectious diseases.
Nigeria’s routine immunization programme provides vaccines against illnesses such as tuberculosis, hepatitis B, polio, diphtheria, tetanus, whooping cough, pneumonia, meningitis, rotavirus diarrhoea, measles and yellow fever. HPV vaccination is also part of the national programme for eligible girls.
Yet many children still miss their first vaccines or fail to complete all recommended doses. Some parents face distance, transport costs, vaccine shortages or conflicting information. Others delay because a child appears healthy or because of rumours about vaccine safety.
This guide explains the immunization schedule in Nigeria in 2026, what each visit is meant to achieve, common concerns parents raise and where families can access vaccination services.
Nigeria’s Recommended Childhood Immunization Schedule
The NPHCDA-branded national schedule currently available through UNICEF lists vaccines at birth, 6 weeks, 10 weeks, 14 weeks, 6 months, 9 months, 12 months and 15 months. It also includes HPV vaccination for eligible girls.
Because Nigeria is introducing or transitioning some vaccines during 2025 and 2026, parents should take their child’s immunization card to every appointment and confirm the current schedule with the health worker in their state.
At Birth
A newborn should receive the following as soon as possible after delivery:
BCG vaccine
BCG helps protect children against severe forms of tuberculosis, particularly tuberculosis meningitis and widespread tuberculosis in young children.
Oral polio vaccine, birth dose
The birth dose of oral polio vaccine is commonly written as OPV0.
Hepatitis B birth dose
The hepatitis B vaccine should be given as early as possible after birth, ideally within the first 24 hours. It helps protect against hepatitis B infection, which can later cause chronic liver disease and liver cancer. The national schedule includes a hepatitis B birth dose in addition to later hepatitis B protection contained in the pentavalent vaccine.
Parents should ask about these vaccines before leaving the hospital, maternity centre or primary healthcare facility.
At 6 Weeks
The national schedule lists:
- Pentavalent vaccine, first dose
- Pneumococcal conjugate vaccine, first dose
- Oral polio vaccine, first routine dose
- Rotavirus vaccine, first dose
- Inactivated polio vaccine, first dose
The pentavalent vaccine protects against five diseases:
- Diphtheria
- Tetanus
- Pertussis, also called whooping cough
- Hepatitis B
- Haemophilus influenzae type b
The pneumococcal vaccine helps protect against serious illnesses caused by pneumococcal bacteria, including some forms of pneumonia, meningitis and bloodstream infection.
Rotavirus vaccination helps protect infants from severe diarrhoea caused by rotavirus. Nigeria introduced rotavirus vaccine into the routine schedule at 6, 10 and 14 weeks.
At 10 Weeks
The recommended vaccines include:
- Pentavalent vaccine, second dose
- Pneumococcal conjugate vaccine, second dose
- Oral polio vaccine, second routine dose
- Rotavirus vaccine, second dose
This visit is important because one dose is not enough to provide the intended level of protection from vaccines that require a series.
At 14 Weeks
The national schedule lists:
- Pentavalent vaccine, third dose
- Pneumococcal conjugate vaccine, third dose
- Oral polio vaccine, third routine dose
- Rotavirus vaccine, third dose
- Inactivated polio vaccine, second dose
Nigeria’s schedule uses two inactivated polio vaccine doses in infancy, alongside oral polio vaccination. Two fractional IPV doses at 6 and 14 weeks are recognised as an effective way to strengthen protection against poliovirus.
Completing the 6, 10 and 14-week visits is essential. A child who receives only the first vaccine visit remains incompletely vaccinated.
At 6 Months
The national schedule includes the first vitamin A dose at six months.
Vitamin A is not a vaccine, but it supports vision, immunity and healthy growth. It is included in child-survival services and is usually given orally.
Some Nigerian states are also introducing malaria vaccination for eligible children. The malaria vaccine is not yet delivered identically across every state, so parents should ask their local primary healthcare centre whether it is available and when their child should begin. In Bauchi State, for example, malaria vaccination was being delivered to eligible children aged 5 to 21 months during a 2026 intensification campaign.
At 9 Months
The national schedule currently available lists:
- First measles-containing vaccine
- Yellow fever vaccine
- Meningitis vaccine
However, Nigeria began a major measles-rubella campaign in 2025 and early 2026 and is preparing to incorporate the combined measles-rubella vaccine into routine immunization. During this transition, the vaccine offered may be labelled measles vaccine or measles-rubella vaccine, depending on location and implementation stage.
Parents should not reject a measles-rubella vaccine because an older card or schedule says “measles.” The combined vaccine protects against both measles and rubella.
Yellow fever vaccination is especially important in Nigeria because yellow fever can cause severe illness and outbreaks.
The meningitis vaccine listed in the schedule helps protect children against meningococcal meningitis, an important concern in parts of Nigeria located within Africa’s meningitis belt.
At 12 Months
The schedule includes the second vitamin A dose.
Vitamin A supplementation normally continues at recommended intervals during early childhood through child-health services. Parents should ask the health worker when the next dose is due.
At 15 Months
The schedule lists the second dose of measles-containing vaccine.
This second-year-of-life visit is important because the first dose does not produce adequate immunity in every child. A second dose helps close that protection gap.
Nigeria’s current immunization strategy is strengthening second-year-of-life vaccination and measles-rubella protection.
HPV Vaccination for Girls
Nigeria introduced HPV vaccination into the national routine immunization programme to protect girls from the types of human papillomavirus responsible for most cervical cancers.
The current routine focus is on girls aged nine years, while catch-up campaigns have reached girls aged 9 to 14 years. Nigeria adopted a single-dose HPV vaccination approach for girls in this age group.
The HPV vaccine does not treat an existing infection. It provides the greatest benefit when given before exposure to HPV later in life.
Parents should ask their child’s school, primary healthcare centre or state immunization team about availability.
| Child’s age | Vaccines or services commonly due |
|---|---|
| At Birth | BCG, OPV0, hepatitis B birth dose |
| 6 weeks | Pentavalent 1, PCV 1, OPV 1, rotavirus 1, IPV 1 |
| 10 weeks | Pentavalent 2, PCV 2, OPV 2, rotavirus 2 |
| 14 weeks | Pentavalent 3, PCV 3, OPV 3, rotavirus 3, IPV 2 |
| 6 months | Vitamin A; malaria vaccine where introduced |
| 9 months | Measles or measles-rubella 1, yellow fever, meningitis vaccine |
| 12 months | Vitamin A |
| 15 months | Second measles-containing or measles-rubella dose |
| Girls aged 9 years | HPV vaccine under routine delivery |
This summary reflects the national schedule currently published through official partner channels, alongside 2026 programme changes. Parents should follow the dates written on the child’s immunization card and confirm any local variation with a qualified health worker.
Why Does My Child Need Several Vaccination Visits?
Some vaccines require more than one dose because the immune system needs repeated exposure to build strong and lasting protection.
The first dose introduces the immune system to the disease antigen. Later doses strengthen and extend the protection. NPHCDA explains that completing every recommended dose gives children the best possible protection.
Missing later doses can leave a child only partially protected.
What If a Child Misses a Vaccine Appointment?
A delayed appointment does not usually mean the entire vaccine series must be restarted.
Parents should return to the health facility with the child’s immunization card as soon as possible. The health worker will review the vaccines already received and arrange catch-up doses based on the child’s age and the national schedule.
Catch-up vaccination means giving missed or delayed vaccines so that a child can become appropriately protected.
Do not avoid the clinic because you feel embarrassed about missing an appointment. Health workers would rather help the child catch up than leave the child unprotected.
Common Immunization Myths and the Facts
Myth 1: “My child is healthy, so vaccination is unnecessary.”
A healthy appearance does not protect a child from future exposure to measles, polio, whooping cough, meningitis or other infectious diseases.
Vaccines are given before exposure because young children can become seriously ill very quickly. NPHCDA notes that the schedule is designed to provide protection early in life, before children encounter life-threatening infections.
Myth 2: “Vaccines cause the diseases they are meant to prevent.”
Routine vaccines are designed to teach the immune system how to recognise and fight specific germs.
They do not give a child the full disease in the way natural infection does. Some vaccines contain weakened or inactive organisms, while others contain only parts of the germ.
A child may develop temporary fever, soreness or swelling after vaccination. These mild reactions are not the same as developing the disease itself.
Myth 3: “Too many vaccines at once will overwhelm the child.”
Children encounter thousands of substances and microorganisms in their environment every day.
Vaccines are carefully scheduled and assessed for use together. Receiving several vaccines during one visit reduces missed opportunities and protects the child earlier.
The immune system can respond to the small number of vaccine antigens without becoming overwhelmed.
Myth 4: “Vaccines cause infertility.”
There is no credible evidence that routine childhood vaccines or the HPV vaccine cause infertility.
The HPV vaccine helps prevent infections that can cause cervical cancer. Nigeria introduced it after regulatory and programme review, and millions of Nigerian girls have received it through national delivery efforts.
Myth 5: “HPV vaccination encourages early sexual activity.”
The HPV vaccine is a cancer-prevention vaccine.
Giving it before possible future exposure does not encourage sexual activity, just as giving hepatitis B vaccination does not encourage behaviours associated with hepatitis transmission.
Vaccination protects the child before exposure can occur.
Myth 6: “Vaccination campaigns are different from routine immunization, so one can replace the other.”
Campaign vaccines and routine vaccines may overlap, but a campaign dose does not always replace every scheduled routine dose.
Parents should allow eligible children to participate in approved campaigns while continuing routine appointments and keeping the immunization card updated.
Myth 7: “A vaccinated child can never become ill.”
No vaccine prevents every possible cause of fever, diarrhoea, pneumonia or meningitis.
Different germs can cause similar illnesses. For example, pneumococcal and pentavalent vaccines protect against important causes of pneumonia and meningitis, but they do not prevent every infection that can affect the lungs or brain.
Vaccination greatly reduces the likelihood of certain serious diseases and often lowers the risk of severe complications.
Are Vaccines Safe?
Vaccines used in Nigeria go through safety, quality and regulatory processes before being included in public programmes.
Mild reactions may include:
- Pain at the injection site
- Mild swelling
- Temporary fever
- Irritability
- Reduced appetite for a short period
These symptoms usually settle without serious problems.
Parents should remain at the vaccination site for the period advised by the health worker and report any unusual or severe reaction immediately.
Seek urgent medical attention if a child develops:
- Difficulty breathing
- Severe weakness or loss of consciousness
- Persistent convulsions
- Extensive swelling
- A very high or persistent fever
- Any symptom that seriously worries the parent
Serious vaccine reactions are uncommon, while the diseases vaccines prevent can cause disability or death.
Can a Child Be Vaccinated During a Mild Illness?
A mild cold, cough or low-grade fever does not always require postponing vaccination.
However, the child should be assessed by the health worker before vaccines are given. Parents should explain any symptoms, recent medicines, allergies or previous reactions.
A child with a serious acute illness may need clinical assessment and temporary postponement, depending on the circumstances.
Parents should not decide to skip vaccination for months without speaking to a qualified professional.
Where Can Parents Access Immunization Services in Nigeria?
Routine immunization is available through many:
- Government primary healthcare centres
- Public hospitals
- Maternal and child health clinics
- Outreach vaccination sessions
- Mobile vaccination teams
- Approved campaign sites
- School-based HPV vaccination programmes
NPHCDA’s primary healthcare system includes routine immunization as a core service, and the agency provides a facility dashboard for locating primary healthcare centres.
Parents can also ask:
- The ward development committee
- A community health worker
- The local government immunization officer
- The State Primary Health Care Development Agency or Board
- A recognised public health facility
- The child’s school during HPV or campaign activities
Routine vaccines supplied through Nigeria’s public immunization programme are intended to be provided without charge at government delivery points. Parents should report unofficial vaccine charges through appropriate state or facility channels. The rotavirus vaccine, for example, was introduced into routine services as a free vaccine for eligible infants.
What Parents Should Take to the Clinic
Bring:
- The child’s immunization card
- The child’s birth information where available
- Any referral or clinic documents
- Details of previous vaccine reactions
- Information about medicines or current illness
The immunization card is important. It shows what the child has received and what is still due.
Take a clear photograph of the card and store it securely as a backup, but continue bringing the original to appointments.
What Should Parents Ask the Health Worker?
Useful questions include:
- Which vaccines is my child receiving today?
- What diseases do they prevent?
- When is the next appointment?
- What mild reactions should I expect?
- Which symptoms require urgent medical attention?
- Has my child missed any dose?
- Is catch-up vaccination required?
- Is the measles-rubella vaccine now being used in this state?
- Is malaria vaccination available here?
- Is my daughter eligible for HPV vaccination?
Before leaving, ask the health worker to write the next appointment date clearly on the card.
How Parents Can Reduce Missed Appointments
Parents can:
- Set a phone reminder immediately after each visit
- Write the next date on a visible household calendar
- Ask a partner or relative to remember the appointment
- Keep transport money aside when possible
- Identify the nearest alternative clinic
- Attend outreach sessions when offered
- Inform the health worker if relocation or travel may interrupt appointments
- Return for catch-up vaccination as soon as possible after a missed date
Vaccination works best when every child receives the full recommended series.
Frequently Asked Questions
Is childhood immunization free in Nigeria?
Vaccines provided under the government routine immunization programme are generally offered free at public vaccination points. A facility may have separate charges for unrelated private services, but parents should ask for clarification if they are asked to pay for a routine vaccine.
Can vaccines be given together?
Yes. Several routine vaccines are designed to be given during the same visit. This protects children earlier and reduces the number of separate clinic trips.
What happens when a child loses the immunization card?
Return to the facility where the vaccines were given. Staff may be able to check facility records and issue a replacement or reconstruct the child’s history. Do not guess which vaccines the child received.
Does a child need routine vaccines after receiving campaign vaccines?
Usually, yes. Campaigns help close population immunity gaps, but children should still complete the routine schedule written on their cards.
Is measles-rubella vaccination replacing the measles vaccine?
Nigeria is transitioning toward the combined measles-rubella vaccine. Implementation may differ by state and timing during 2026. Parents should accept approved measles-rubella vaccination when offered and confirm the next routine dose with the health worker.
How many HPV doses do Nigerian girls need?
Nigeria adopted a single-dose HPV schedule for girls aged 9 to 14 years, with routine delivery currently centred on girls aged nine. Girls with certain immune conditions may require individual medical advice.
Should vaccination stop if the child cries or develops mild fever?
No. Crying, mild fever and soreness can occur after vaccination. Ask the health worker how to keep the child comfortable and when to seek medical attention.
Final Thoughts
The Nigerian immunization schedule begins at birth and continues through infancy, the second year of life and adolescence.
Parents should not wait until a disease outbreak occurs before seeking vaccination. The safest approach is to begin on time, keep every appointment, retain the immunization card and return promptly for catch-up doses after any delay.
Nigeria’s programme is also evolving. Measles-rubella vaccination is being integrated, HPV vaccination is reaching eligible girls, and malaria vaccines are expanding in selected states.
The most reliable schedule for an individual child is the one confirmed by a trained health worker and recorded on the child’s immunization card.
