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.”

Lecture by Judge Albie Sachs: ‘Sites of memory, sites of conscience’
2015-03-23

Judge Albie Sachs

Human rights activist and former Constitutional Court Judge, Albie Sachs, will deliver a public lecture on the Bloemfontein Campus. The topic of his discussion will be ‘Sites of memory, sites of conscience’. This lecture will form part of a series that focuses on how the creative arts represent trauma and memory – and how these representations may ultimately pave the way to healing historical wounds.

The details of the event are:
Date: Thursday 26 March 2015
Time: 12:30
Venue: Albert Wessels Auditorium, Bloemfontein Campus
RSVP: Jo-Anne Naidoo at Naidooja@ufs.ac.za
A South African Sign Language interpreter will be present at the event.

Joining Judge Sachs on stage as respondent will be Dr Buhle Zuma, a young scholar and lecturer at the University of Cape Town's Psychology Department.

Expressing experiences of trauma
Judge Sachs is no stranger to the use of the arts as a way of expressing the inarticulable and overwhelming experiences of trauma. Targeted as an anti-apartheid freedom fighter, he lost his right arm and was blinded in one eye in a car bomb attack in 1988. As a judge of the Constitutional Court, he spearheaded conversations about the role of the arts in our constitutional democracy. This has led to the installation of some of the best artworks by South African artists at the Constitutional Court.

Vice-Chancellor’s Lecture Series on Trauma, Memory, and Representations of the Past
This lecture will launch of the Vice Chancellor’s Lecture Series on Trauma, Memory and Representations of the Past. It forms part of a five-year research project led by Prof Pumla Gobodo-Madikizela, funded by the Mellon Foundation. The event is hosted by the UFS Trauma, Forgiveness and Reconciliation Studies.

“One of the most remarkable aspects of trauma,” Prof Gobodo-Madikizela says, “is the loss of language, a moment of rupture that produces what some scholars have referred to as ‘speechless terror’. The arts, in all its forms – literary, performance, and visual – are a viable mechanism through which the unspeakable, traumatic past may be represented.”

These artistic forms of representing trauma are at the heart of this Vice-Chancellor’s Lecture Series. “We are interested not only in how experiences that transcend language are represented through the arts,” Prof Gobodo-Madikizela explains, “but also in probing the limits of trauma theory, and how the creative arts might be employed to bear witness in a way that may open up the possibility of healing.”

Dr Buhle Zuma
Former Mandela Rhodes scholar and one of the 2011 Mail & Guardian’s 200 Young South Africans, Dr Zuma is particularly interested in issues at the heart of our rainbow nation. His current research revolves around the question of freedom: what it means to be human for black people after centuries of dehumanisation, and the role of desire and fantasy in the political imagination of post-apartheid South Africa.
