Vaccines and immunization: The past, present and future in Nigeria

Abstract

Vaccines are arguably the most important public health tools available today. Since the successful eradication of smallpox with the use of the vaccine, many vaccines have become available to man. Of great importance to public and child health are the vaccines against the so-called six killer diseases of childhood-measles, pertussis, diphtheria, tetanus, tuberculosis and poliomyelitis. In the last 2 decades, effective vaccines against the major causes of pneumonia, another childhood killer, have become available. Data from many parts of the world including African countries have shown the benefits of the pneumococcal and Haemophilus influenzae type b vaccines. The scientific world is still searching for appropriate candidate vaccines for malaria and HIV infection. Despite the availability and effectiveness of many vaccines, the benefits to a country is highly dependent on a viable and sustainable health system which include adequate financing, dynamic and motivated workforce, strong partnerships and effective community participation. If well deployed, available vaccines as elucidated in this discourse can accelerate the achievements of the Millennium Development Goals in Nigeria and many other developing countries.

Key words: Vaccines, Immunizations, Nigeria.
