1. Congratulations on attaining a C2 rating Prof, how do you feel about it and did you expect to make it?

I am very grateful and also excited about the news of having received a C2 rating from the NRF. When you apply for an NRF rating, you have to be confident that you will receive a rating, because if you do not receive a rating, then there is a waiting period before you are allowed to apply again. I anticipated a C3 rating, so receiving a C2 rating was really a bonus for me.

2. Take us through the process this went through until you were eventually given a rating by NRF?

The NRF rating process is very lengthy and rigorous, taking approximately a year to complete, including 4-6 external expert reviews and final discussion by an assessment panel. The rating is based on research output and impact over the past eight years, as perceived by national and international peer reviewers, with the quality of your research benchmarked against researchers at a national and international level. The application itself is very detailed and requires you to use critical thinking and apply your mind. It is not something that can be done overnight! In preparation for applying for an NRF rating, you have to ensure that you consistently publish high quality research output and in high impact journals, over a period of at least eight years. Establishing an academic profile takes years, hence you need to have a main focus area of research, with long- and short-term research objectives to guide your own research, post-graduate student research and collaborations. I also strongly believe in collaboration, not only with colleagues at our own institution, nationally and internationally, but also with people in practice, where you actually do your research. The more you collaborate, the more you learn and progress. Helen Keller’s powerful quote has certainly stood the test of time for me, “Alone we can do so little; together we can do so much”.

3. What does it mean for you as a researcher?

As a researcher with a C2 rating it means that you are recognised as an established researcher with a sustained record of productivity in your field of expertise, as recognised by your peers, and that you engage with and are recognised by the international science community. Apart from recognition, acquiring an NRF rating also means that this rating must be
maintained, hence you should maintain your research focus, sustain your research activities and work towards achieving your long-term gaols. An advantage of an NRF rating is that it could be beneficial for you when you apply for grant funding, awards and promotion. In essence, you have to remain committed to your research career, which requires far more than a 40- or 45-hour working week! ”.

4. What is your field of specialty and please give a brief explanation of it?

Since 2014, as an advocate for public health pharmacy, my focus is directed towards the macro-level activities of public health, specifically strengthening the WHO building block of ‘medical products, technologies, and vaccines’, to ensure people have sustained access to, and appropriately use essential medical products, vaccines and technologies that are safe, effective, and of assured quality. The main goals of my research are to strengthen healthcare services, improve public health, and contribute towards reaching the sustainable development goal of good health and well-being, focusing on vaccination as a vital pillar of antimicrobial stewardship and the rational use of medicines.

5. You have been doing a lot of work around vaccines and Covid-19 lately, what is science telling us about vaccination?

History has shown that vaccination is the most significant global health intervention ever, second to clean water, saving millions of lives each year. The main goal of vaccination is to protect people throughout the life course against severe disease and death, thereby reducing suffering and improving quality of life. Over the last 18 months, science has clearly
shown that the COVID-19 vaccines are effective at protecting against severe disease, hospitalisation, and death, caused by the different variants of SARS-CoV-2. Furthermore, science has also shown that COVID-19 vaccines are safe to use and that the benefits of vaccination by far outweigh any possible risks of adverse effects.

6. What can you tell the readers about the recently discovered Omicron variant?

Currently the data about the Omicron variant is still limited and more information should become available in the very near future. Once a new variant is identified, it could impact on how easily the virus spreads (transmissibility), the severity of illness it may cause and the effectiveness of the existing COVID-19 vaccines in protecting against infection, severe disease and death. What we have observed from recent data, especially in the Gauteng Province, is that the rate of new cases of SARS-CoV-2 is much higher compared to previous weeks, with a positivity rate as high as 30-35%, suggesting that Omicron is more transmissible than the Delta variant. Although hospitalisation is also increasing, it is low relative to the community case rate. It also seems as though symptoms are milder, compared to symptoms caused by the Delta variant, with patients testing positive for COVID-19 coincidently when admitted to hospital for another illness or surgical procedure. The duration of hospital stay is much shorter compared to previous waves, with few patients requiring mechanical ventilation. Data has also shown that hospitalisation for severe COVID-19 is mainly amongst unvaccinated people. Preliminary evidence also suggests an increased risk of reinfection amongst people who have already had COVID-19. We have seen a similar situation with the Delta variant where people who were previously infected with the Beta variant were not protected from re-infection with the Delta variant.

7. What is it that people have to do to survive under the difficult circumstances of Covid-19?

At this stage of the pandemic we all have to be very vigilant in a number of ways. The most important action to take is to get vaccinated against COVID-19, as vaccination is the most powerful tool we currently have. Data on the Omicron variant is still limited, but it has already been shown that protection against COVID-19 infection is reduced, because the virus has a mutated spike protein that evades neutralisation by the antibodies that were produced by both previous natural infection and vaccination. However, you are still protected against severe disease and death because, as illustrated by laboratory-based studies, the T-cell response does not appear to be badly affected by the mutations, hence clearing infected cells and preventing viral replication. Recent data released by Discovery, has shown a decrease in protection against infection from 80% against Delta to 33% against Omicron, amongst people vaccinated with two doses of the Pfizer vaccine. Also, protection against severe disease and hospitalisation decreased from 93% against Delta, to 70% against Omicron, with lower protection for the elderly (60-69 years: 67%; 79-79 years: 60%). In addition to vaccination, we have to adhere to public health measures to protect ourselves and those around us. These include wearing a mask, sanitising or washing hands, social distancing, avoiding large crowds and making sure that indoor spaces are well ventilated, including when travelling, by keeping doors and windows open at all times.

8. A lot of people ask questions about variants, it was Delta the other time and now Omicron, what is happening as the virus mutates?

What we know about the new Omicron variant is that it has at least 50 mutations, some of which are concerning. There are more than 30 genetic mutations affecting the spike protein, which is the part of the virus that binds to human cells, allowing it to gain entry. Some of these mutations have also been found in other variants such as the Delta variant, but those variants had far fewer mutations. Viruses will always mutate, and mutations will give rise to new variants. This can be avoided when vaccination coverage is high, because the higher the proportion of vaccinated people, the smaller the chance for the virus to spread and the fewer opportunities for the virus to multiply, mutate and eventually give rise to a new variant.

9. Any further information you wish to share with the readers?

Unfortunately, people who are at highest risk of contracting the new variant are those who are not vaccinated, and who are not adhering to public health measures to protect themselves. Research has shown that natural and vaccine-induced immunity wane over time due to a decrease in neutralising antibodies. Although we are expecting to see more breakthrough infections with the Omicron variant, we expect people to be less infectious because of underlying T-cell responses which are still reserved, hence clearing infected cells and preventing viral replication. Booster doses will be needed in future, as they will provide longer-term protection against serious COVID-19 disease. Recent data on the Delta variant has shown that a third dose of the Pfizer vaccine increased protection against symptomatic SARS-COV-2 infection from 62% to 94%, in people who had previously received the primary series of two doses at least 20 weeks prior to boosting.

10. How would you use your new status as a NRF rated researcher to make a difference in your field?

In light of the COVID-19 pandemic, research in my focus areas of rational medicine use, and vaccination as a pillar for antimicrobial stewardship for AMS, will continue, and specifically address concerns raised about antimicrobial resistance potentially causing the next pandemic. I have been awarded a competitive NRF grant for a project, ‘Leveraging COVID-19 to build confidence in vaccination and promote antimicrobial stewardship in South Africa’. This project includes developing and testing educational interventions to empower healthcare providers to promote vaccination with confidence, thereby increasing public demand for vaccination as a human right. In addition to SMU-based co-investigators and students, I have already established international and national collaborations for this project, including co-investigators from University of Strathclyde, UK; Network for Education and Support in Immunisation, University of Antwerp, Belgium; East Africa Centre for Vaccines and Immunization (ECAVI), Egerton University, Kenya; SA Medical Research Council; University of Cape Town; University of the Witwatersrand; and University of Pretoria. I will continue to use my own enthusiasm for research in public health pharmacy to build capacity and inspire students to disseminate their work to the scientific community. Lastly, I consider the relationship and connection between research, education and community engagement as indispensable. This belief informs my social responsibility to focus my research towards achieving universal healthcare and health for all by 2030, in line with the National Development Plan of South Africa. I therefore always aim to integrate theory and practice, and to instil into students the principles of social responsibility. To achieve this, I have to set an example to my students, provide service and research within my discipline and stay abreast of new developments in practice. I quote Mahatma Gandhi who said, “The best way to find yourself, is to lose yourself in the service of others.”

Portfolio Committee on Higher Education Science and Innovation Upbeat on Developments at SMU

by Lorato | Oct 22, 2021 | All News, SMU Media

The Portfolio Committee on Higher Education Science and Innovation conducted an oversight visit at the Sefako Makgatho Health Sciences University on 19 October 2021. In attendance were members of the SMU Council led by Ms Mmanare Mamabolo (Deputy Chairperson of Council), University Management led by the Vice-Chancellor Professor Peter Mbati, representatives of organised labour and members of the Student Representative Council. Other members of Council in attendance were Mr Thabiso Lekoana and Dr Mangaliso Mahlaba. The Portfolio Committee was led by its Chairperson, Honorable Nompendulo Mkhatshwa accompanied by Honorable Tebogo Letsie.

The Committee embarked on a tour of the Campus to inspect both infrastructure and research facilities, which included the construction site of the new 2,000 bed student residence, the new boundary wall, NHLS laboratories, Virology/ Microbiology laboratories and the new Entrepreneurship Incubation Centre. Following the Campus tour, the Vice-Chancellor made a presentation to the Committee on the University’s five year Strategic Plan, the progress made as well as prospects and challenges.

As part of securing the future of SMU, Prof Mbati explained to members of the Portfolio Committee that Council had approved a New Business Model to ensure the financial sustainability of the University. Key to this model is increasing the numbers of students to 13,500, exploring new options for student funding, commercialization initiatives and a strong third stream income strategy. Such initiatives are important, according to the Vice-Chancellor, given some of the challenges related to student funding, student debt, backlog maintenance, and the dire need for additional office space.

Mbati added that the University had made significant strides in creating a new institutional culture preceded by the signing of a Culture Compact by all stakeholders (management, labour and SRC) committing themselves separately and collectively to work for the good of the University. It was also emphasized that the roll out of the Performance Management System has been given sufficient attention for all employees to continuously contribute to a high performance culture. Professor Mbati emphasized the importance of every stakeholder playing their specified roles and not conflating them, in order for SMU to be successful.

Honorable Letsie emphasized the importance of stability on campus as an important recipe for success. He further cautioned that factionalism and lack of cohesion in the governance and management of institutions leads to dysfunctionality and ultimately universities being placed under administration. The Chairperson of the Parliamentary Committee said it is their responsibility to ensure that the higher education sector delivers on its promises and mandate, and visits such as this provides them with an opportunity to get first-hand experience on how institutions are delivering on their mandates. The Committee was generally upbeat on the progress and developmental trajectory of SMU and promised to embark on future visits to check progress on the many exciting initiatives currently being undertaken at the University.
