To debunk myths and manage expectations around the vaccine, Investec Life invited Professor Francois Venter, one of South Africa’s foremost experts on the virus, to share his insights on a webcast. A Professor of Medicine at Wits University, Francois is also a leading light in the fight against HIV/Aids.
Joining Francois in the conversation, moderated by Kalay Maistry, is Sinenhlanhla Nzama, Head Product Actuary at Investec Life, who offered his views on how the vaccine could impact life insurance and the "uncertainty mindset" the pandemic has helped us adopt.
When will things return to normal?
But how soon with things normalise? Francois gives three scenarios on how the virus will play out:
The best-case scenario, that the scientific community strongly predicts is the most likely, is the "common cold scenario", where you will occasionally get the virus and your body will learn to fend it off like the common cold. "There’ll be Covid circulating in the air and on surfaces, but it won’t be life threatening," explains Francois. In this case, things could return to normal sooner rather than later.
The second scenario is less than ideal and will occur if Covid-19 immunity wanes quicker than we think. This would mean that you'd need to get an updated vaccine every three to five years, and drug researchers would need to stay one step ahead of the virus.
Finally, there’s the worst-case “Armageddon” scenario, where the virus becomes so mutagenic that most people will require a new vaccine each year to avoid getting too sick. The most vulnerable among us – like the elderly and diabetics – will live in continual fear of getting infected and face masks and social distancing will stay with us indefinitely.

The "South African variant" is a misnomer
"There are probably thousands of variants all competing with each other to be the next most effective and fit version that's going to take over," says Francois.Even then, naming mutations by their location is problematic: the place where a mutation occurs and the place where it’s picked may be different; it also wrongly inculcates the kind of irrational prejudice that continues to drive Sinophobia and finger pointing in many parts of the world.
Herd immunity unlikely
“There will be no herd immunity, there will be just a circulating virus going round and round that we'll all get every couple of months,” explains Prof Venter.So, the goal isn’t herd immunity but rather individual immunity. Much like the flu, this means acquiring the ability to cope with the range of illnesses caused by Covid-19 rather trying to eradicate the virus completely.
This is particularly important for those with high-risk comorbidities like diabetes. Current clinical reports show that diabetics with Covid-19 are twice as likely to need intensive hospitalisation.
“The vaccines are not going to give you sterilising immunity, they’re not going to protect you absolutely from infection, but they are going to stop all the horrible things that can happen,” says Francois, like hospitalisation, sever illness and long Covid.
The rise of vaccine nationalism
The rise of vaccine nationalism, where some countries buy-up and hoard more vaccines than they require, is ugly but "depressingly predictable", says Francois, and until that self-corrects we should continue to maintain physical distancing and wear masks as we always have since the pandemic started.
With first world countries moving quickly towards vaccinating 90%–100% of their populations, and third world countries still at less than ten percent, it raises an ethical dilemma, says Sinenhlanhla. "You still have the elderly and people with chronic conditions who are actually last in line compared to someone who stays in a first world country who's 20 and has got a fighting chance against the virus.”

How vaccines might impact your insurance cover
“It’s still uncertain. One thing with insurance is that we deal very well with risk where you know the possible outcomes and the probability of those outcomes. Here we know the possible outcomes but not much about the probabilities, that's why it's uncertain,” says Sinenhlanhla.
These probabilities include the possibility that even if you don't have the vaccine, you will be protected because of a strong population immunity.
“But the question for us as an insurer to consider is will there be any substantial risk differential between those who are vaccinated and those who are not? Does this risk differential change for future strains or variants of the coronavirus?” Not to mention the mystery surrounding long Covid and the potential impact to insurers down the line.
If it does become possible to quantify the risk, then antivaxxers may face increased premiums – a principle that’s universally well accepted in risk underwriting for everything from heart conditions to smoking, says Sinenhlanhla.

Lessons learned from the HIV/Aids crisis
Another lesson we've learned from the HIV Aids is that that health is actually a moral imperative. “I think too often over the last 20 to 30 years, it's been kind of the economy is the most important thing, I think we've seen now the economy is actually at the mercy of populations being healthy.”
One of the biggest lessons we've learnt from the current crisis is that it's given us a better understanding of how to deal with uncertainty. "We’re living in a very volatile and uncertain world and I think as we evolve as societies, some of the key lessons we’re learning from this virus is how do you respond to such uncertainty especially if it's so widespread,” says Sinenhlanhla. The answer, he says, is closer collaboration between government, business and Individuals.
