Infantile immunisation is the process of making babies or toddlers resistant or immune to certain infections or diseases. It is vaccinating babies and young children to protect their health from serious and potentially life-threatening diseases. Immunisation gives infants the immunity to fight diseases that can cause long-term health issues or even death.

According to the United Nations Children’s Fund (UNICEF) in 2019, Vaccines are products usually given in childhood to protect against serious, often deadly diseases. By stimulating the body’s natural defences, they prepare the body to fight the disease faster and more effectively.

Infantile immunisation is important because infants are vulnerable to infections, and their immune systems are not fully developed. Immunisation provides them with protection during this critical period of their lives. Vaccines are given to babies to protect them against serious illnesses like polio, which can cause paralysis; measles, which can cause brain swelling and blindness; whooping cough (pertussis); and tetanus, which can cause painful muscle contractions and difficulty eating and breathing, especially in newborns.

Abdullah Sani, a 39-year-old survivor of polio, said, “Growing up, I realised I couldn’t do what children my age could do with their legs. I wanted to run, jump, play with my friends and do everything my peers were doing, but I couldn’t. I felt terrible.

At the age of three, doctors told my parents that I would never walk again. My mum cried profusely as she resolved with my dad to fight the disease that had disabled me. I was taken to many hospitals and traditional healers in search of a cure, but the search was fruitless as there was no cure for polio. The disease took my ability to walk.”

World Health Organisation (WHO) stated in 2024 that vaccines and immunisation currently prevent 3.5 million to 5 million deaths yearly from diseases like diphtheria, tetanus, pertussis, influenza, and measles globally.

In Nigeria, the National Programme on Immunization (NPI) in the year 2014 stated that routine immunisation of children in Nigeria is carried out using the following vaccines: BCG ( Bacilli Calmette Guerin) at birth or as soon as possible after birth; OPV (Oral Polio Vaccine) at birth and 6, 10, and 14 weeks of age; DPT (Diphtheria, pertussis, tetanus) at 6, 10, and 14 weeks of age; Hepatitis B at birth, 6 and 14 weeks; Measles at 9 months of age; Yellow Fever at 9 months of age and Vitamin A at 9 months and 15 months of age.

Nigerian Federal Ministry of Health states that a child is considered fully vaccinated if they have received a BCG vaccination against tuberculosis; three doses of DPT to prevent diphtheria; pertussis (whooping cough); tetanus and at least three doses of polio vaccine; and one dose of measles vaccine. All these vaccinations should be received for five visits during the first year of life, including the doses delivered at birth. According to this schedule, children between 12–23 months would have completed their immunisations and be fully immunised.

According to UNICEF, in 2019, infantile immunisation was one of the most effective ways to protect babies from preventable diseases. Health experts say that vaccinating your child not only safeguards their health but also contributes to the overall well-being of the community.

 Vaccines are safe and effective and have played a crucial role in reducing and eradicating dangerous diseases. By following the recommended immunisation schedule, parents can protect their babies from the serious risks of infectious diseases, giving them the best possible start in life.
