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.”

Workplace discrimination and unfair practices explored in new book

Two law scholars, Dr Denine Smit and Dr Damian Viviers, from the Faculty of Law at the University of the Free State (UFS) recently launched a book titled Vulnerable Employees, which was inspired by their interest in researching, creating awareness and providing a legal exposition in relation to employees who are vulnerable and experience prejudice and dignity violations in the workplace. These include workplace bullying, appearance-based discrimination, those who are gender fluid or have mental-health conditions.
“Dr Viviers, who is also a former student of mine, and I, have been working together for years and share a common understanding in relation to our various topics of interest. We often share the same train of thought. This is how we came to work together to produce this book,” said Dr Smit.


Research focused on employee challenges in the workplace

The book expands on the field of knowledge regarding certain categories of employees who, as a consequence of various mutable, immutable and semi-immutable characteristics, as well as behavioural experiences, are rendered vulnerable in their employment relationships. The book draws on various social, psychological and other empirical considerations, as well as comparative legal research from foreign and international law, in order to expand on the legal position under the South African legal framework governing these conditions. While the book first and foremost constitutes a compendium of research to be used for this purpose, it also serves as a practical guide for all legal practitioners, human resources managers, other labour stakeholders and the judiciary.

Book draws strength in other academic fields
Vulnerable Employees was launched on 28 July 2017 at the UFS library, to an audience of academics and students, with a panel discussion made up of the authors and two other panellists. One of the panellists was Dr Katinka Botha, a leading psychiatrist in the Free State who has a wealth of experience in this field. “Her selection as a panellist was motivated by the various significant inter-disciplinary considerations and intersections between psychology, psychiatry and law, contained in the book,” said Dr Smit. 
“Dr Botha’s expertise was invaluable in shedding light on mental-health considerations during the panel discussion.” 
Mr Lesley Mokgoro, the other panellist, is a leading labour law practitioner, as well as director and head of the Dispute Resolution Practice Group at Phatshoane Henney Attorneys. “His years of experience working with all role players in the employment domain, as well as his extensive legal knowledge and expertise, made him uniquely qualified to serve on the panel and deliver an opinion of the practical and academic value of the book,” said Dr Smit.


Workplace policies key to securing employee rights

There are a number of growing trends in the workplace that could shape the practice of labour law or workplace policies. Dr Smit said the need for employers to regulate workplace culture, particularly in relation to bullying, harassment and unfair discrimination, in line with the South African legal framework, was a fundamental need in all workplaces. Effective workplace policies may be used to clearly outline the relevant “dos and don’ts” to employees, as well as the procedures and processes that may be followed in order to address such conduct. Workplace policies serve to advance legal certainty and efficiency, since the rights and obligations of all role players are clearly demarcated, or should be, in terms of a well-drafted and considered policy. 
The book is one of several publications produced by Dr Smit in collaboration with Dr Viviers on the topic of workplace discrimination and the law. The two scholars are working on another book to be published at the end of 2017.
