Opinion article by Angie Vorster, Clinical Psychologist in the School of Clinical Medicine, University of the Free State.


The World Mental Health Day campaign has chosen ‘Mental Health in an Unequal World’ as the theme for 2021. This is partly to raise awareness of the distinct polarisation between countries and individuals that has been highlighted by the COVID-19 pandemic over the past two years.  Access to health-care resources is significantly impinging the ability of countries across the world to address the effects of the pandemic, and stark inequality regarding pivotal elements such as access to vaccines has become visible. Obtaining, storing, and distributing vaccines has proven to add another burden to countries that are already financially and resource-impeded. Yet, once South Africa was lucky enough to secure adequate amounts of vaccines, we were faced with a baffling dilemma. How to get our residents to actually take it? In trying to understand the psychology behind vaccine hesitancy, it is interesting to note that the World Health Organisation listed vaccine hesitancy (delaying or refusing vaccination) as one of the top ten threats to global health – well before the outbreak of the COVID-19 virus. 

Understanding why people refuse or resist vaccination

To understand why people – who are otherwise reasonable, conscientious, and informed individuals – would refuse or resist vaccination, it is helpful to look at the 5C model. The first aspect is confidence – the extent to which the person trusts that the vaccine is safe and will in fact do what it is said to do. Confidence is also affected by the level of trust that the individual has in the system that dispatches the vaccine – consequently, individuals who are hesitant to vaccinate are likely to be suspicious of authority figures and structures. Another factor is the number of constraints that individuals face in accessing the vaccine. If there are many barriers (e.g., unable to afford transport to the vaccination site, unable to take time off work, etc.) in terms of the calculation of costs versus benefits, obviously it would be easier to delay or refuse vaccination. Interestingly, perceived scarcity makes items/events more desirable. Perhaps it is the very fact that the vaccine is free and available that makes people not interested in receiving it. 

Having a sense of collective responsibility and altruism are important characteristics in those who submit to vaccination. People who refuse vaccination tend to be more individualistically orientated and less motivated by the greater good of all, than by their own personal preferences. And this brings us to the final C, which is complacency. People who perceive the risk of COVID-19 as low tend to feel less urgency to vaccinate. Unfortunately, these are the patients who admit to COVID ward front-line workers that they now regret not getting vaccinated when they had the chance; instead, they frequently come to this realisation once their prognosis is terminal and they are facing the harrowing reality of dying, separated from their loved ones. 

And then we all know someone who believes in an ‘alternative’ explanation for the COVID-19 virus and its vaccine. There are many hypotheses as to why people prefer conspiracy theories over scientific truth – some of which include the fact that the science behind understanding viruses and their prevention is quite abstract and too complicated for lay people to understand. Unless they witness the devastating impact of the virus first-hand – it may be difficult to comprehend that an invisible entity can do so much damage. Another explanation is that the truth of a natural disaster such as a pandemic, which can occur at any time, randomly, and without warning, catching humanity off guard, is just too frightening to accept. So, it makes us feel safer to believe that humans ARE in fact in control and actually created COVID-19 for some larger sinister goal. Otherwise, we are left to contemplate how utterly vulnerable we all really are. Instead, we deny reality and substitute it with something that makes us feel a bit better. 

How to encourage all citizens to get vaccinated

So, how do we encourage all citizens to get vaccinated in order for our society to regain some pre-pandemic normality? Force, anger, and frustration (which are undoubtedly justified, particularly by those who work on the front line, and by those who have lost loved ones due to this virus) are not going to get us there. Instead, we need religious and other leaders to set the example and publicly advocate for vaccination. We need to tailor the information to the vast majority of South Africans who are not science-literate, making it accessible and understandable in their home language. Unfortunately, there is a significant percentage who will not be swayed by these actions, and for these fellow South Africans I have the following message:

It does not matter anymore whether or not COVID-19 is in fact the product of a global conspiracy and whether or not the companies that create vaccines do so only for financial gain. It does not matter that this all happened very fast and that we all realised how terribly weak and vulnerable the human body is. What does matter is that this virus is here. In our homes, our schools, cities, and country. And the only way to get rid of it, or at least to continue our lives alongside it, is for all of us to be vaccinated. We have science – facts, not opinions or feelings or theories or beliefs – to tell us that vaccines are safe and effective. In ten years from now, this will be the plague of 2020. I hope that you will be able to say that you were brave, even though you were scared, even though you were unsure, even though you might have been fine without the vaccine, but that you were strong enough and kind enough and human enough to do this small thing for the greater good of humanity. And our children will thank you for restoring connection and hugs, concerts, and playtime at school without distancing and sanitiser and masks. You will have done something important. For your community and your country and in fact, the world. This is your chance to be part of a great victory of humanity over a seemingly insurmountable tide of death and suffering. Our hope lies in you. Take this great responsibility, wear it with pride and importance, and meet us at the other side of COVID-19.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
