Dr Samantha Potgieter.

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.”

Engaging men to act against gender-based violence in the Southern African context.

This was the theme of the second International Leah Tutu Symposium, hosted by the Gender Initiative of Trauma, Forgiveness and Reconciliation Studies of the University of the Free State (UFS) on Tuesday 24 February 2015.

What does it mean to be man? How can men become active in the fight against gender-based violence? And when does one say: enough is enough? Questions like these set the tone as highly-respected individuals such as Dr Mamphela Ramphele, Prof Rob Morrell, Lisa Vetten and Andy Kawa took to the stage in the Odeion on the Bloemfontein Campus.

Leah Tutu
Unfortunately, Mrs Leah Tutu could not attend this year’s event, but she still managed to send sparks of wit and insight into the auditorium. In her video message, Mrs Tutu referred to the fact that our country has “consigned discriminatory legislation to the rubbish bin of the past”, but we continue to inhabit a divided society.

“We have a constitution and bill of rights that should have sounded the death knell for patriarchy. But women are unsafe across the land,” Mrs Tutu said. “Our freedom cost too much to be left out in the rain,” she urged.

Ndiyindoda! Yes, you are a man
In Dr Ramphele’s keynote address, “Ndiyindoda! Yes, you are a man”, she scrutinised the dominant masculinity model that has supported an alpha-male mentality for millennia. A mentality that celebrates dominance, power and control – where the winner takes it all. How then, can we expect our young boys to embrace the value system of a human rights culture?

“Gender equality is at the heart of our constitutional democratic values. Yet, our society continues to privilege and celebrate the alpha male as a masculinity model,” Dr Ramphele said. This dissonance can only produce conflict and violence.

We encourage our young men to be gentle, communicative, caring people who show their emotions. And when they do, what do we as women do? Do we encourage them?

“Or do we join those who call them wimps, moffies, sissies? How do we respond when they are ridiculed?” Dr Ramphele asked. Are we, as mothers, fathers and grandparents willing to socialise our children to acknowledge a diversity of masculinities as equally valid in our society?

The new man and the new woman of the 21st century need to be liberated from the conflict-ridden dominant masculinity model. They need to be able to shape their identity in line with a value system of human rights as enshrined in our constitution.

Perhaps Dr Ramphele’s message could be summed up by one sentence: You cannot find Ubuntu in a culture of dominance.
