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.”

UFS Council confirms decision to integrate student residences
2007-09-14

At its quarterly meeting held today (Friday, 14 September 2007) the Council of the University of the Free State (UFS) confirmed the decision taken at its previous meeting that the student residences of the UFS should be racially integrated.

The decision was taken with an overwhelming majority with only one vote against it and will be implemented in January 2008.

The Council tabled and noted the resolution of the Convocation of 11 September 2007 concerning the Council’s initial decision of 8 June 2007 and urged the management to continue to be sensitive, empathetic and inclusive in dealing with the concerns and views of all stakeholders.

The Council also gave all interested parties the assurance that any suggestions that could assist in the successful implementation of its decision would be considered and called once again on all stakeholders to make proposals to the management of the UFS so as to ensure a well-managed process of integration and managing diversity in residences.

In this regard it welcomed the suggestion made by the alumni of the UFS for the introduction of a Diversity Scorecard for residences which would include a multi-dimensional range of indicators and incentives for residences. This could include the diversity profile of a residence, the academic performance of the students in a residence, inter-residence activities and community service projects launched by students.

According to the Rector and Vice-chancellor of the UFS, Prof. Frederick Fourie, the Council hereby also restated the educational motive for the integration of residences, which meant that from an educational point of view, students who had the knowledge and skills to manage diversity would have a distinct advantage in the workplace and in life.

“Today’s decision is a major step forward for the Council and the UFS to achieve a broad consensus around the promotion of diversity at the UFS and in its residences, as the institution has always been committed to giving the best education to students in a diverse and non-racial environment. I would like to call on current students, prospective students, parents, alumni and other stakeholders to make this work in the best interests of the university and its students,” Prof. Fourie said.

He added that the UFS had established several task teams comprising staff and students to implement the Council’s decision of 8 June 2007 and that much work had already been done to identify critical areas and tasks ahead of implementation in January 2008.
