He received the degree PhD in Medical Virology (h.c.) during the Faculty of Health Sciences graduation ceremony.

With the case study of Caprise 256, a young woman in his AIDS study, and her potent antibody that kills HIV, Prof Salim S Abdool Karim, honorary doctorate recipient, conveyed the message of the power of science, knowledge and discovery to motivate the graduates from the Faculties of Health Sciences and Theology and Religion at the University of the Free State (UFS).

Prof Karim, renowned for his ground-breaking research in AIDS and COVID-19, received the degree PhD in Medical Virology (h.c.) during Thursday’s (18 April 2024) graduation ceremony.

From humble beginnings

“It is great honour and privilege to be here and accept this honorary doctorate. I first went to university in 1978 and wanted to study engineering but did not have the money to pay for registration as I come from a poor background. So, I attended classes anywhere. But then I was accepted to study medicine at the University of Natal with a full scholarship and that was the end of my career in engineering.

“From that humble beginning to today where you might have watched me on TV trying to share with you what we know about COVID-19 and other infectious diseases, is a great culmination of a career and I am deeply honoured and privileged to receive this honorary doctorate”, he said shortly after accepting his fifth honorary degree.

Prof Abdool Karim, a clinical infectious disease epidemiologist who is widely recognised for scientific contributions to AIDS and COVID-19, also shared with graduates the last 20 years of his academic journey with an example to illustrate how exciting the acquisition of knowledge and thrill of discovery can be. He talked about his work with AIDS and says it remains one of the world’s greatest challenges. Last year, he said, there were 1.3 million new infections and over 700 000 deaths as a result of AIDS.

Caprisa 256’s antibody

“I have devoted almost 40 years of research to looking for solutions for the AIDS problem and one of the biggest problems we are dealing with is the high rate of HIV, particularly in young girls. In 2003 we started a study to begin to understand why young women are at such a high risk of HIV.

“We enrolled hundreds of young women without HIV. We provided them with all kinds of knowledge to try and keep them HIV-free. Amongst those women we enrolled was participant 256, a young lady and she acquired HIV infection two years later in 2005.”

It would later turn out that this young woman, codename Caprisa 256, has a very special antibody – the kind that can kill a wide range of HIV – which is referred to as a broadly neutralising antibody. It is an antibody researchers tried to ellicit in making vaccine.

It turned out that not only is her antibody able to kill a wide range of HIV, it is a highly potent antibody. After testing and cloning a cell in the blood and growing it in a culture and harvesting the antibody, it was genetically manipulated to get a better antibody.

The Director of the Centre for the AIDS Programme of Research in South Africa (Caprisa), explained that it took two-and-a-half years to manufacture this antibody in the US and the first South African was injected with it in 2020. They enrolled over 1 000 women in a study with half of the women receiving the placebo and half the antibody. The question whether it works, or protects humans from the HIV will only be answered next year, Prof Abdool Karim explained. 

The 3 Ps

“What I am trying to convey to you, it’s the power of science, the power of knowledge, the power of discovery and when each of you goes out into the world, I want to leave you with the message that there are three valuable lessons that I have learned in this 20-year journey of Caprisa 256.

“The first one is find your passion, find something that excites you when you wake up in the morning. There will be people that would want to pull you down, you will have to stand firm. You have to show that you are passionate and committed and regardless of the obstacles, you will persevere. Find your passion and persevere. And as you do that, always remember the pursuit of excellence. I know that each of you will bring to this world your own humanity, your own values, and we are in this world, in a situation where we are in desperate need of people who will bring their humanity and their wisdom to bear.”

Prof Francis Petersen, Vice-Chancellor and Principal of the UFS, congratulated Prof Abdool Karim on his honorary degree and praised his groundbreaking research on Aids and COVID-19, as well as his exceptional work in medical virology over the years. “Prof Abdool Karim led the South African response to COVID-19, providing us as the public, as well as the government with scientific advice on the virus, new variants, and flattening the curve. Prof Abdool Karim has the ability to easily explain complex science to members of the general public in such a way that they are able to understand it. He played a critical role during the pandemic, and for this as well as for his research on Aids, South Africa is indebted to him.

Stem cell research and human cloning: legal and ethical focal points
2004-07-29

   

(Summary of the inaugural lecture of Prof Hennie Oosthuizen, from the Department of Criminal and Medical Law at the Faculty of Law of the University of the Free State.)

 

In the light of stem cell research, research on embryo’s and human cloning it will be fatal for legal advisors and researchers in South Africa to ignore the benefits that new bio-medical development, through research, contain for this country.

Legal advisors across the world have various views on stem cell research and human cloning. In the USA there is no legislation that regulates stem cell research but a number of States adopted legislation that approves stem cell research. The British Parlement gave permission for research on embryonic stem cells, but determined that it must be monitored closely and the European Union is of the opinion that it will open a door for race purification and commercial exploitation of human beings.

In South Africa the Bill on National Health makes provision for therapeutical and non therapeutical research. It also makes provision for therapeutical embryonical stem cell research on fetuses, which is not older than 14 days, as well as for therapeutical cloning under certain circumstances subject to the approval of the Minister. The Bill prohibits reproductive cloning.

Research on human embrio’s is a very controversial issue, here and in the rest of the world.

Researchers believe that the use of stem cell therapy could help to side-step the rejection of newly transplanted organs and tissue and if a bank for stem cell could be built, the shortage of organs for transplants would become something of the past. Stem cells could also be used for healing of Alzheimer’s, Parkinson’s and spinal injuries.

Sources from which stem cells are obtained could also lead to further ethical issues. Stem cells are harvested from mature human cells and embryonic stem cells. Another source to be utilised is to take egg cells from the ovaries of aborted fetuses. This will be morally unacceptable for those against abortions. Linking a financial incentive to that could become more of a controversial issue because the woman’s decision to abort could be influenced. The ideal would be to rather use human fetus tissue from spontaneous abortions or extra-uterine pregnancies than induced abortions.

The potential to obtain stem cells from the blood of the umbilical cord, bone-marrow and fetus tissue and for these cells to arrange themselves is known for quite some time. Blood from the umbilical cord contains many stem cells, which is the origin of the body’s immune and blood system. It is beneficial to bank the blood of a newborn baby’s umbilical cord. Through stem cell transplants the baby or another family member’s life could be saved from future illnesses such as anemia, leukemia and metabolic storing disabilities as well as certain generic immuno disabilities.

The possibility to withdraw stem cells from human embrio’s and to grow them is more useable because it has more treatment possibilities.

With the birth of Dolly the sheep, communities strongly expressed their concern about the possibility that a new cloning technique such as the replacement of the core of a cell will be used in human reproduction. Embryonic splitting and core replacement are two well known techniques that are associated with the cloning process.

I differentiate between reproductive cloning – to create a cloned human embryo with the aim to bring about a pregnancy of a child that is identical to another individual – and therapeutically cloning – to create a cloned human embryo for research purposes and for healing human illnesses.

Worldwide people are debating whether to proceed with therapeutical cloning. There are people for and against it. The biggest ethical objection against therapeutical cloning is the termination of the development of a potential human being.

Children born from cloning will differ from each other. Factors such as the uterus environment and the environment in which the child is growing up will play a role. Cloning create unique children that will grow up to be unique individuals, just like me and you that will develop into a person, just like you and me. If we understand this scientific fact, most arguments against human cloning will disappear.

Infertility can be treated through in vitro conception. This process does not work for everyone. For some cloning is a revolutionary treatment method because it is the only method that does not require patients to produce sperm and egg cells. The same arguments that were used against in vitro conception in the past are now being used against cloning. It is years later and in vitro cloning is generally applied and accepted by society. I am of the opinion that the same will happen with regard to human cloning.

There is an argument that cloning must be prohibited because it is unsafe. Distorted ideas in this regard were proven wrong. Are these distorted ideas justified to question the safety of cloning and the cloning process you may ask. The answer, according to me, is a definite no. Human cloning does have many advantages. That includes assistance with infertility, prevention of Down Syndrome and recovery from leukemia.
