Immunology and world health: key contributions from the global community.

The contributions of immunology to world health must be seen in the context of the severe disadvantage prevailing in many countries. Low life expectancy, high infant and maternal mortality rates, and continued prevalence of infections as causes of preventable deaths highlight what vaccines can do to improve the situation. This paper will briefly review some major new international health programs, including the GAVI Alliance; the Global Polio Eradication Initiative; the Global Fund to Fight AIDS, Tuberculosis and Malaria; the President's Emergency Plan for AIDS Relief; and the Global Malaria Action Plan.

Vaccines of the future.

Vaccines of the future can be divided into three broad groups, namely those of the near future (<10 years); the medium-term future (10-19 years); and the long-term future (20-50 years). For the near future, there is some "low hanging fruit" which is clearly on the horizon, such as a Vi-conjugate vaccine for typhoid or a protein-based vaccine for Neisseria meningitidis serogroup B. Just slightly more distant will be vaccines for shigellosis and a common protein vaccine for Streptococcus pneumoniae.

Vaccines and future global health needs.

Increased international support for both research into new vaccines and their deployment in developing countries has been evident over the past decade. In particular, the GAVI Alliance has had a major impact in increasing uptake of the six common infant vaccines as well as those against hepatitis B and yellow fever. It further aims to introduce pneumococcal and rotavirus vaccines in the near future and several others, including those against human papillomavirus, meningococcal disease, rubella and typhoid not long after that.

Festschrift for Professor Margaret Burgess AO.

In honour of the retirement of our director Margaret Burgess, National Centre for Immunisation Research and Surveillance (NCIRS) held a Festschrift on 5th to 6th February 2004. The themes of the event were Vaccines for the 21st Century and Congenital and Neonatal Infections. International guests attended the Festschrift, as well as over 180 colleagues and co-workers from across Australia.

A healthier climate for the funding of vaccine research.

Vaccination is a marvel of scientific endeavor that benefits the masses. Yet the laissez-faire economy may not provide a sufficient push for vaccine research and development. The current climate that drives this globally important venture is examined here.

The double helix and immunology.

The immune system can recognize and produce antibodies to virtually any molecule in the Universe. This enormous diversity arises from the ingenious reshuffling of DNA sequences encoding components of the immune system. Immunology is an example of a field completely transformed during the past 50 years by the discovery of the structure of DNA and the emergence of DNA technologies that followed.

Gates, GAVI, the glorious global funds and more: all you ever wanted to know.

Global immunization programmes have achieved some remarkable successes. In 1977, Frank Fenner's Commission declared smallpox to have been eradicated by an 11-year-long intensive campaign. The Expanded Programme on Immunization encompassed six important childhood vaccines and reached over three-quarters of the world's children.

One cell, one antibody: prelude and aftermath.

This essay seeks to summarize one scientist's pilgrim's progress through the world of antibody formation, attempting to capture the flavor of problems as encountered within their times. It seeks to portray a world where the direct template hypothesis ruled the day, where the function of lymphocytes was unknown, let alone the difference between T and B cells, and where antibody genes were but a dream. Struggles to establish the credentials of the clonal selection hypothesis are presented in some detail, as are the implications which followed the 'one cell - one antibody' discovery.

Funding options for research: facing the market as well as government.

Parasitology is a challenge. At one level, the structural and genetic complexities of parasites provide ample technical challenges in regard to an understanding of parasite variability and adaptability, epidemiological diversity, drug resistance, etc. The intricacies of host parasite relationships including the immunology of parasitism will continually surprise yet frustrate the vaccine developer and keep the bravest immunoparasitologist busy and creative for decades.
