8-1 RESEARCH AND DEVELOPMENT OF CONTRACEPTIVE VACCINE

8-1


Project Scope and Relationship to China's Agenda 21

This project is designed to lead to the development of a safe, simple, effective, economical, and reversible contraceptive vaccine for women and ultimately for men as well. The project has been developed in accordance with programme area 7A of China's Agenda 21 - Population Growth Control - and will contribute to poverty alleviation and improvement of every aspect of human life and sustainable development (all chapters).

1. Background

Population concerns play a decisive role in all human endeavours and are a crucial part of any strategy for achieving sustainable development. This is particularly true for China, the most populous country in the world, whose population of almost 1.2 billion constitutes 22 percent of the global total.

China has made remarkable progress in family planning during the last twenty years, with the total fertility rate, birth and death rates, and average expected life span approaching the average standards of developed countries. Its population growth during the past years has been 0.2 billion less than projected. Yet even if China's long-term population control strategy is fully successful, its population will not reach a stable level until the middle of the next century, after the population has already reached 1.6 billion.

Such intense population pressures will place enormous strains on every aspect of human life and development, accelerate the decline of China's limited natural resource base, and adversely affect sustainable development throughout the world. As a result, China is now seeking to develop additional methods of controlling population in a safe, effective, economic, and equitable manner.

China has the ability to produce and provide most of the contraceptive agents and devices which have been marketed internationally. Yet the devices currently available in clinical practice cannot satisfy the various needs of people at different economic and education levels and with differing access to health services. Research is therefore under way at 20 different family planning institutes throughout China to develop alternative methods of fertility regulation. Yet money for such research is severely limited due to the enormous amount of funds needed to provide free family planning services to all in China. In fact, funding for research, development constitutes only 0.25 percent of the total family planning budget.

China is one of only three countries in the world (along with the United States and India) now working on development of a contraceptive vaccine, a new generation method of birth control. It is expected that one dose of such a vaccine would last 1 to 1.5 years, thus proving simpler, more economical, and more effective than other alternatives, yet still reversible. Although most of the work to date has been on developing a vaccine for women, progress has also been made, and will continue on the more difficult task of isolating antigens to be used in a vaccine for men. China hopes to continue its work and eventually be able to provide these vaccines to other developing countries.

The research program for a contraceptive vaccine has been included in the Seventh and Eighth Five-Year plans, as well as on a list of the Hi-Tech Research and Development Programme. Safety and toxicological studies on three kinds of contraceptive vaccines have been conducted on primates, and a phase I clinical trial is scheduled to begin next year.

Yet because of the shortage of funds and lack of necessary equipment, China lags behind in such fields as the expression of glycoprotein using bioengineering technologies, the synthesis of biodegradable polymers, and pharmacological and toxicological evaluation methods. China is therefore seeking technical cooperation in research methodology as well as assistance in upgrading its equipment, instruments, and communication system. It also hopes that by building its capacity to perform research and development of alternative contraceptive methods, it will be able to attract the return home of overseas Chinese scientists who are presently training to work in this important field.

5. Benefits

Successful completion of the project will enable China to make available a safe, simple, effective, and economical vaccine throughout China as well as other countries. The resulting population control benefits could have widespread implications for alleviating poverty, reducing the burden on the national and global environment, and further every aspect of sustainable development.
