As COVID-19 vaccines continue to be a topical issue in South Africa and indeed in the world itself, the Department of Human Resources held a webinar for the UFS community on 10 September that delved deeper into the questions surrounding the vaccine. 

Dr Samantha Potgieter, infectious disease expert at the Universitas Academic Hospital and affiliated Lecturer in the Department of Internal Medicine at the University of the Free State, addressed some commonly raised concerns about the COVID-19 vaccine and how it affects us.

Dr Potgieter started off by saying that coronaviruses have been causing outbreaks among humans for millennia. While COVID-19 is relatively mild and self-limiting in 80% of patients, 20% of patients are at risk of developing severe disease.
She said before a vaccine could be introduced to a population, it had to go through rigorous testing and clinical trials. Only once safety has been confirmed, it can be released and distributed. 

“This process usually takes about ten years; this is what we are used to. But it has happened much quicker for the COVID-19 vaccine, and I think this is a fact that many people misinterpret – that the evidence might not be that robust, which is certainly not the case. COVID-19 vaccines have gone through all this rigorous testing, thousands of patients had volunteered for trial testing studies. The point is that we already had the technology, vaccination is not something new to humans. So, these preclinical trials were able to happen very quickly, and because of the large number of infections and because the focus of the entire world was on finding a cure, it was a very set process to get these trials through the adequate phases.” 

She said the COVID-19 vaccine was approved by national regulators, manufactured to exacting standards, and only thereafter distributed – as is the case for all drugs released into the market.

How does the vaccine work?

Dr Potgieter said the vaccine works by producing antibodies against the COVID-19 virus. If you are infected with the COVID-19 virus after getting vaccinated, these antibodies bind to the virus and stop it from replicating.

“When you get infected with a disease such as COVID-19, natural antibodies are produced by the immune system to fight the disease. If you get infected again, the immune system will remember how to respond, and quickly destroy the virus. A vaccine can do the same, but without the risk of disease from natural infection. Vaccines work by imitating a bacteria or virus using either mRNA in the case of the COVID-19 vaccine, or a dead or weakened version of the bacteria or virus. The vaccine raises the body’s alarm. It trains the body to recognise and fight the virus. When the body encounters the real-deal virus, it is primed and ready to fight for the body’s health.”

She said South Africa had the mRNA vaccine in the form of the Pfizer vaccine, and the adenoviral vector vaccine in the form of the Johnson & Johnson vaccine.

Why should you get the vaccine?

Dr Potgieter said vaccines are safe and effective, and the most compelling reasons for getting vaccinated are the following:

-To protect yourself from severe disease
-To protect those around you who may be at risk of severe disease
-To restore the social and economic platforms of the country, and the world at large.
She said that while the vaccine does not prevent you from getting COVID-19, it offers better protection against the development of severe disease, and vaccinated people had 50% less chance of spreading the virus.
The most common side effects of the vaccine are the following:
-Pain at the injection site
-Swollen lymph nodes
-Fever
-Fatigue
-Headache
-Myalgia (muscle pain)

“These are indications that the immune system is mounting a response. When it mounts a response, it produces antibodies,” she said.

Answers to commonly asked questions are the following:

1. Can the vaccine alter my DNA?
“No, it goes nowhere near the nucleus of the cell.”

2. What happens when you get COVID in between the first and second doses?
“Some protection is conferred after the first dose, but maximum protection is conferred two weeks after the second dose. Vaccination is still advised.” 

Dr Potgieter said patients who were between vaccinations still show better recovery results than those without.

3. What about natural immunity?
“Natural immunity might confer better protection, but it runs the risk of severe disease. Yes, immunity can be gained through natural immunity, it can be gained through vaccination, and it can certainly be gained by a combination of the two.”

4. What about long-term side effects?
“Serious side effects that cause long-term health problems following any vaccination are very rare, including the COVID-19 vaccination.”

Gender bias still rife in African Universities

Gender bias still rife in African Universities

Women constitute about 30% of student enrolment in African universities, and only about 6% of African professors are women. This is according to the chairperson of Gender Studies at the University of Cape Town, Prof Amina Mama.

Prof Mama was delivering a lecture on the topic “Rethinking African Universities” as part of Women’s Day celebrations at the University of the Free State (UFS) today.

She says the gender profile suggests that the majority of the women who work in African universities are not academics and researchers, but rather the providers of secretarial, cleaning, catering, student welfare and other administrative and support services.

She said that African universities continue to display profound gender bias in their students and staffing profiles and, more significantly, are deeply inequitable in their institutional and intellectual cultures. She said women find it difficult to succeed at universities as they are imbued with patriarchal values and assumptions that affect all aspects of life and learning.

She said that even though African universities have never excluded women, enrolling them presents only the first hurdle in a much longer process.

“The research evidence suggests that once women have found their way into the universities, then gender differentiations continue to arise and to affect the experience and performance of women students in numerous ways. Even within single institutions disparities manifest across the levels of the hierarchy, within and across faculties and disciplines, within and between academic and administrative roles, across generations, and vary with class and social background, marital status, parental status, and probably many more factors besides these”, she said.

She lamented the fact that there is no field of study free of gender inequalities, particularly at postgraduate levels and in the higher ranks of academics. “Although more women study the arts, social sciences and humanities, few make it to professor and their research and creative output remains less”, she said.

Prof Mama said gender gaps as far as employment of women within African universities is concerned are generally wider than in student enrolment. She said although many women are employed in junior administrative and support capacities, there continues to be gross under-representation of women among senior administrative and academic staff. She said this disparity becomes more pronounced as one moves up the ranks.

“South African universities are ahead, but they are not as radically different as their policy rhetoric might suggest. A decade and a half after the end of apartheid only three of the 23 vice-chancellors in the country are women, and women fill fewer than 30% of the senior positions (Deans, Executive Directors and Deputy Vice-Chancellors)”, she said.

She made an observation that highly qualified women accept administrative positions as opposed to academic work, thus ensuring that men continue to dominate the ranks of those defined as ‘great thinkers’ or ‘accomplished researchers’.

“Perhaps women simply make realistic career choices, opting out of academic competition with male colleagues who they can easily perceive to be systematically advantaged, not only within the institution, but also on the personal and domestic fronts, which still see most African women holding the baby, literally and figuratively”, she said

She also touched on sexual harassment and abuse which she said appears to be a commonplace on African campuses. “In contexts where sexual transactions are a pervasive feature of academic life, women who do succeed are unlikely to be perceived as having done so on the basis of merit or hard work, and may be treated with derision and disbelief”, she said.

She, however, said in spite of broader patterns of gender and class inequality in universities, public higher education remains a main route to career advancement and mobility for women in Africa.

“Women’s constrained access has therefore posed a constraint to their pursuit of more equitable and just modes of political, economic and social development, not to mention freedom from direct oppression”, she said.

Prof Mama concluded by saying, “There is a widely held agreement that there is a need to rethink our universities and to ensure that they are transformed into institutions more compatible with the democratic and social justice agendas that are now leading Africa beyond the legacies of dictatorship, conflict and economic crisis, beyond the deep social divisions and inequalities that have characterised our history”.

She said rethinking universities means asking deeper questions about gender relations within them, and taking concerted and effective action to transform these privileged bastions of higher learning so that they can fulfil their pubic mandate and promise instead of lagging behind our steadily improving laws and policies.
